General Electric BWR/4 STS iii Rev. 4.0

ABSTRACT

This NUREG contains the improved Standard Technical Specifications (STS) for General 

Electric Boiling Water Reactor/4 (BWR/4) plants. The changes reflected in Revision 4 result 

from the experience gained from plant operation using the improved STS and extensive public 

technical meetings and discussions among the Nuclear Regulatory Commission (NRC) staff and 

various nuclear power plant licensees and the Nuclear Steam Supply System (NSSS) Owners 

Groups.

The improved STS were developed based on the criteria in the Final Commission Policy 

Statement on Technical Specifications Improvements for Nuclear Power Reactors, dated 

July 22, 1993 (58 FR 39132), which was subsequently codified by changes to Section 36 of Part 

50 of Title 10 of the Code of Federal Regulations (10 CFR 50.36) (60 FR 36953). Licensees are 

encouraged to upgrade their technical specifications consistent with those criteria and 

conforming, to the practical extent, to Revision 4 to the improved STS. The Commission 

continues to place the highest priority on requests for complete conversions to the improved 

STS. Licensees adopting portions of the improved STS to existing technical specifications 

should adopt all related requirements, as applicable, to achieve a high degree of standardization 

and consistency.

Users may access the STS NUREGs in the PDF format at (http://www.nrc.gov). Users may 

print or download copies from the NRC Web site.

1.1 Definitions

------------------------------------------------------------NOTE-----------------------------------------------------------

The defined terms of this section appear in capitalized type and are applicable throughout these 

Technical Specifications and Bases.

-------------------------------------------------------------------------------------------------------------------------------

Term Definition

ACTIONS ACTIONS shall be that part of a Specification that prescribes 

Required Actions to be taken under designated Conditions 

within specified Completion Times.

AVERAGE PLANAR LINEAR The APLHGR shall be applicable to a specific planar height 

HEAT GENERATION RATE and is equal to the sum of the [LHGRs] [heat generation rate 

(APLHGR) per unit length of fuel rod] for all the fuel rods in the specified 

bundle at the specified height divided by the number of fuel 

rods in the fuel bundle [at the height].

CHANNEL CALIBRATION A CHANNEL CALIBRATION shall be the adjustment, as 

necessary, of the channel output such that it responds within 

the necessary range and accuracy to known values of the 

parameter that the channel monitors. The CHANNEL 

CALIBRATION shall encompass all devices in the channel 

required for channel OPERABILITY and the CHANNEL 

FUNCTIONAL TEST. Calibration of instrument channels with 

resistance temperature detector (RTD) or thermocouple 

sensors may consist of an inplace qualitative assessment of 

sensor behavior and normal calibration of the remaining 

adjustable devices in the channel. The CHANNEL 

CALIBRATION may be performed by means of any series of 

sequential, overlapping, or total channel steps.

CHANNEL CHECK A CHANNEL CHECK shall be the qualitative assessment, by 

observation, of channel behavior during operation. This 

determination shall include, where possible, comparison of the 

channel indication and status to other indications or status 

derived from independent instrument channels measuring the 

same parameter.

CHANNEL FUNCTIONAL TEST A CHANNEL FUNCTIONAL TEST shall be the injection of a 

simulated or actual signal into the channel as close to the 

sensor as practicable to verify OPERABILITY of all devices in 

the channel required for channel OPERABILITY. The 

CHANNEL FUNCTIONAL TEST may be performed by means 

of any series of sequential, overlapping, or total channel steps.
Definitions

1.1 Definitions

CORE ALTERATION CORE ALTERATION shall be the movement of any fuel, 

sources, or reactivity control components, within the reactor 

vessel with the vessel head removed and fuel in the vessel. 

The following exceptions are not considered to be CORE 

ALTERATIONS:

a. Movement of source range monitors, local power range 

monitors, intermediate range monitors, traversing incore 

probes, or special movable detectors (including 

undervessel replacement), and

b. Control rod movement, provided there are no fuel 

assemblies in the associated core cell.

Suspension of CORE ALTERATIONS shall not preclude 

completion of movement of a component to a safe position.

CORE OPERATING LIMITS The COLR is the unit specific document that provides cycle 

REPORT (COLR) specific parameter limits for the current reload cycle. These 

cycle specific limits shall be determined for each reload cycle 

in accordance with Specification 5.6.3. Plant operation within 

these limits is addressed in individual Specifications.

DOSE EQUIVALENT I-31 DOSE EQUIVALENT I-131 shall be that concentration of I-131 

(microcuries/gram) that alone would produce the same thyroid 

dose as the quantity and isotopic mixture of I-131, I-132, I-133, 

I-134, and I-135 actually present. The thyroid dose conversion 

factors used for this calculation shall be those listed in 

[Table III of TID-14844, AEC, 1962, "Calculation of Distance 

Factors for Power and Test Reactor Sites" or those listed in 

Table E-7 of Regulatory Guide 1.109, Rev. 1, NRC, 1977, or 

ICRP 30, Supplement to Part 1, page 192-212, Table titled, 

"Committed Dose Equivalent in Target Organs or Tissues per 

Intake of Unit Activity"].

EMERGENCY CORE COOLING The ECCS RESPONSE TIME shall be that time interval from 

SYSTEM (ECCS) RESPONSE when the monitored parameter exceeds its ECCS initiation 

TIME setpoint at the channel sensor until the ECCS equipment is 

capable of performing its safety function (i.e., the valves travel 

to their required positions, pump discharge pressures reach 

their required values, etc.). Times shall include diesel 

generator starting and sequence loading delays, where 

applicable. The response time may be measured by means of 

any series of sequential, overlapping, or total steps so that the 

entire response time is measured. In lieu of measurement, 

response time may be verified for selected components 

provided that the components and methodology for verification 

have been previously reviewed and approved by the NRC.

1.1 Definitions

END OF CYCLE RECIRCULA- The EOC RPT SYSTEM RESPONSE TIME shall be that time 

TION PUMP TRIP (EOC RPT) interval from initial signal generation by [the associated turbine 

SYSTEM RESPONSE TIME stop valve limit switch or from when the turbine control valve 

hydraulic oil control oil pressure drops below the pressure 

switch setpoint] to complete suppression of the electric arc 

between the fully open contacts of the recirculation pump 

circuit breaker. The response time may be measured by 

means of any series of sequential, overlapping, or total steps 

so that the entire response time is measured, [except for the 

breaker arc suppression time, which is not measured but is 

validated to conform to the manufacturer's design value].

ISOLATION SYSTEM The ISOLATION SYSTEM RESPONSE TIME shall be that 

RESPONSE TIME time interval from when the monitored parameter exceeds its 

isolation initiation setpoint at the channel sensor until the 

isolation valves travel to their required positions. Times shall 

include diesel generator starting and sequence loading delays, 

where applicable. The response time may be measured by 

means of any series of sequential, overlapping, or total steps 

so that the entire response time is measured. In lieu of 

measurement, response time may be verified for selected 

components provided that the components and methodology 

for verification have been previously reviewed and approved 

by the NRC.

LEAKAGE LEAKAGE shall be:

a. Identified LEAKAGE

1. LEAKAGE into the drywell, such as that from pump 

seals or valve packing that is captured and 

conducted to a sump or collecting tank, or

2. LEAKAGE into the drywell atmosphere from 

sources that are both specifically located and 

known either not to interfere with the operation of 

leakage detection systems or not to be pressure 

boundary LEAKAGE,

b. Unidentified LEAKAGE

All LEAKAGE into the drywell that is not identified 

LEAKAGE,

c. Total LEAKAGE

Sum of the identified and unidentified LEAKAGE, and

LEAKAGE (continued)

d. Pressure Boundary LEAKAGE

LEAKAGE through a nonisolable fault in a Reactor 

Coolant System (RCS) component body, pipe wall, or 

vessel wall.

[ LINEAR HEAT GENERATION The LHGR shall be the heat generation rate per unit length of 

RATE (LHGR) fuel rod. It is the integral of the heat flux over the heat transfer 

area associated with the unit length. ]

LOGIC SYSTEM FUNCTIONAL A LOGIC SYSTEM FUNCTIONAL TEST shall be a test of all 

TEST logic components required for OPERABILITY of a logic circuit, 

from as close to the sensor as practicable up to, but not 

including, the actuated device, to verify OPERABILITY. The 

LOGIC SYSTEM FUNCTIONAL TEST may be performed by

General Electric BWR/4 STS 1.2-1 Rev. 4.0

1.0 USE AND APPLICATION

1.2 Logical Connectors

PURPOSE The purpose of this section is to explain the meaning of logical 

connectors.

Logical connectors are used in Technical Specifications (TS) to 

discriminate between, and yet connect, discrete Conditions, Required 

Actions, Completion Times, Surveillances, and Frequencies. The only 

logical connectors that appear in TS are AND and OR. The physical 

arrangement of these connectors constitutes logical conventions with 

specific meanings.

BACKGROUND Several levels of logic may be used to state Required Actions. These 

levels are identified by the placement (or nesting) of the logical 

connectors and by the number assigned to each Required Action. The 

first level of logic is identified by the first digit of the number assigned to a 

Required Action and the placement of the logical connector in the first 

level of nesting (i.e., left justified with the number of the Required Action). 

The successive levels of logic are identified by additional digits of the 

Required Action number and by successive indentions of the logical 

connectors.

When logical connectors are used to state a Condition, Completion Time, 

Surveillance, or Frequency, only the first level of logic is used, and the 

logical connector is left justified with the statement of the Condition, 

Completion Time, Surveillance, or Frequency.

EXAMPLES The following examples illustrate the use of logical connectors.

This example represents a more complicated use of logical connectors. 

Required Actions A.1, A.2, and A.3 are alternative choices, only one of 

which must be performed as indicated by the use of the logical connector 

OR and the left justified placement. Any one of these three Actions may 

be chosen. If A.2 is chosen, then both A.2.1 and A.2.2 must be 

performed as indicated by the logical connector AND. Required 

Action A.2.2 is met by performing A.2.2.1 or A.2.2.2. The indented 

position of the logical connector OR indicates that A.2.2.1 and A.2.2.2 are 

alternative choices, only one of which must be performed.

Completion Times

1.3

General Electric BWR/4 STS 1.3-1 Rev. 4.0

1.0 USE AND APPLICATION

1.3 Completion Times

PURPOSE The purpose of this section is to establish the Completion Time 

convention and to provide guidance for its use.

BACKGROUND Limiting Conditions for Operation (LCOs) specify minimum requirements 

for ensuring safe operation of the unit. The ACTIONS associated with an 

LCO state Conditions that typically describe the ways in which the 

requirements of the LCO can fail to be met. Specified with each stated 

Condition are Required Action(s) and Completion Time(s).

DESCRIPTION The Completion Time is the amount of time allowed for completing a 

Required Action. It is referenced to the time of discovery of a situation 

(e.g., inoperable equipment or variable not within limits) that requires 

entering an ACTIONS Condition unless otherwise specified, providing the 

unit is in a MODE or specified condition stated in the Applicability of the 

LCO. Required Actions must be completed prior to the expiration of the 

specified Completion Time. An ACTIONS Condition remains in effect and 

the Required Actions apply until the Condition no longer exists or the unit 

is not within the LCO Applicability.

If situations are discovered that require entry into more than one 

Condition at a time within a single LCO (multiple Conditions), the 

Required Actions for each Condition must be performed within the 

associated Completion Time. When in multiple Conditions, separate 

Completion Times are tracked for each Condition starting from the time of 

discovery of the situation that required entry into the Condition.

Once a Condition has been entered, subsequent divisions, subsystems, 

components, or variables expressed in the Condition, discovered to be 

inoperable or not within limits, will not result in separate entry into the 

Condition, unless specifically stated. The Required Actions of the 

Condition continue to apply to each additional failure, with Completion 

Times based on initial entry into the Condition.

However, when a subsequent division, subsystem, component, or 

variable expressed in the Condition is discovered to be inoperable or not 

within limits, the Completion Time(s) may be extended. To apply this 

Completion Time extension, two criteria must first be met. The 

subsequent inoperability:

a. Must exist concurrent with the first inoperability and

b. Must remain inoperable or not within limits after the first inoperability 

is resolved.
Completion Times

1.3

General Electric BWR/4 STS 1.3-2 Rev. 4.0

1.3 Completion Times

DESCRIPTION (continued)

The total Completion Time allowed for completing a Required Action to 

address the subsequent inoperability shall be limited to the more 

restrictive of either:

a. The stated Completion Time, as measured from the initial entry into 

the Condition, plus an additional 24 hours or

b. The stated Completion Time as measured from discovery of the 

subsequent inoperability.

The above Completion Time extensions do not apply to those 

Specifications that have exceptions that allow completely separate reentry into the Condition (for each division, subsystem, component, or 

variable expressed in the Condition) and separate tracking of Completion 

Times based on this re-entry. These exceptions are stated in individual 

Specifications.

The above Completion Time extension does not apply to a Completion 

Time with a modified "time zero." This modified "time zero" may be 

expressed as a repetitive time (i.e., "once per 8 hours," where the 

Completion Time is referenced from a previous completion of the 

Required Action versus the time of Condition entry) or as a time modified 

by the phrase "from discovery . . ."

EXAMPLES The following examples illustrate the use of Completion Times with 

different types of Conditions and changing Conditions.

EXAMPLE 1.3-1

36 hours

Condition B has two Required Actions. Each Required Action has its own 

separate Completion Time. Each Completion Time is referenced to the 

time that Condition B is entered.
Completion Times

1.3

General Electric BWR/4 STS 1.3-3 Rev. 4.0

1.3 Completion Times

EXAMPLES (continued)

The Required Actions of Condition B are to be in MODE 3 within 12 hours 

AND in MODE 4 within 36 hours. A total of 12 hours is allowed for 

reaching MODE 3 and a total of 36 hours (not 48 hours) is allowed for 

reaching MODE 4 from the time that Condition B was entered. If MODE 3 

is reached within 6 hours, the time allowed for reaching MODE 4 is the 

next 30 hours because the total time allowed for reaching MODE 4 is 

36 hours.

If Condition B is entered while in MODE 3, the time allowed for reaching 

MODE 4 is the next 36 hours.

EXAMPLE 1.3-2

36 hours

When a pump is declared inoperable, Condition A is entered. If the pump 

is not restored to OPERABLE status within 7 days, Condition B is also 

entered and the Completion Time clocks for Required Actions B.1 

and B.2 start. If the inoperable pump is restored to OPERABLE status 

after Condition B is entered, Conditions A and B are exited, and therefore, 

the Required Actions of Condition B may be terminated.

When a second pump is declared inoperable while the first pump is still 

inoperable, Condition A is not re-entered for the second pump. 

LCO 3.0.3 is entered, since the ACTIONS do not include a Condition for 

more than one inoperable pump. The Completion Time clock for 

Condition A does not stop after LCO 3.0.3 is entered, but continues to be 

tracked from the time Condition A was initially entered.

EXAMPLES (continued)

While in LCO 3.0.3, if one of the inoperable pumps is restored to 

OPERABLE status and the Completion Time for Condition A has not 

expired, LCO 3.0.3 may be exited and operation continued in accordance 

with Condition A.

While in LCO 3.0.3, if one of the inoperable pumps is restored to 

OPERABLE status and the Completion Time for Condition A has expired, 

LCO 3.0.3 may be exited and operation continued in accordance with 

Condition B. The Completion Time for Condition B is tracked from the 

time the Condition A Completion Time expired.

On restoring one of the pumps to OPERABLE status, the Condition A 

Completion Time is not reset, but continues from the time the first pump 

was declared inoperable. This Completion Time may be extended if the 

pump restored to OPERABLE status was the first inoperable pump. A 

24 hour extension to the stated 7 days is allowed, provided this does not 

result in the second pump being inoperable for > 7 days.

When one Function X subsystem and one Function Y subsystem are 

inoperable, Condition A and Condition B are concurrently applicable. The 

Completion Times for Condition A and Condition B are tracked separately 

for each subsystem starting from the time each subsystem was declared 

inoperable and the Condition was entered. A separate Completion Time 

is established for Condition C and tracked from the time the second 

subsystem was declared inoperable (i.e., the time the situation described 

in Condition C was discovered).

EXAMPLES (continued)

If Required Action C.2 is completed within the specified Completion Time, 

Conditions B and C are exited. If the Completion Time for Required 

Action A.1 has not expired, operation may continue in accordance with 

Condition A. The remaining Completion Time in Condition A is measured 

from the time the affected subsystem was declared inoperable (i.e., initial 

entry into Condition A).

It is possible to alternate between Conditions A, B, and C in such a 

manner that operation could continue indefinitely without ever restoring 

systems to meet the LCO. However, doing so would be inconsistent with 

the basis of the Completion Times. Therefore, there shall be 

administrative controls to limit the maximum time allowed for any 

combination of Conditions that result in a single contiguous occurrence of 

failing to meet the LCO. These administrative controls shall ensure that 

the Completion Times for those Conditions are not inappropriately 

extended.

A single Completion Time is used for any number of valves inoperable at 

the same time. The Completion Time associated with Condition A is 

based on the initial entry into Condition A and is not tracked on a per 

valve basis. Declaring subsequent valves inoperable, while Condition A 

is still in effect, does not trigger the tracking of separate Completion 

Times.

EXAMPLES (continued)

Once one of the valves has been restored to OPERABLE status, the 

Condition A Completion Time is not reset, but continues from the time the 

first valve was declared inoperable. The Completion Time may be 

extended if the valve restored to OPERABLE status was the first 

inoperable valve. The Condition A Completion Time may be extended for 

up to 4 hours provided this does not result in any subsequent valve being 

inoperable for > 4 hours.

If the Completion Time of 4 hours (plus the extension) expires while one 

or more valves are still inoperable, Condition B is entered.

ACTIONS Table.
Completion Times

1.3

General Electric BWR/4 STS 1.3-8 Rev. 4.0

1.3 Completion Times

EXAMPLES (continued)

The Note allows Condition A to be entered separately for each inoperable 

valve, and Completion Times tracked on a per valve basis. When a valve 

is declared inoperable, Condition A is entered and its Completion Time 

starts. If subsequent valves are declared inoperable, Condition A is 

entered for each valve and separate Completion Times start and are 

tracked for each valve.

If the Completion Time associated with a valve in Condition A expires, 

Condition B is entered for that valve. If the Completion Times associated 

with subsequent valves in Condition A expire, Condition B is entered 

separately for each valve and separate Completion Times start and are 

tracked for each valve. If a valve that caused entry into Condition B is 

restored to OPERABLE status, Condition B is exited for that valve.

Since the Note in this example allows multiple Condition entry and 

tracking of separate Completion Times, Completion Time extensions do 

not apply.

qualifies for the 25% extension, per SR 3.0.2, to each performance after 

the initial performance. The initial 8 hour interval of Required Action A.1 

begins when Condition A is entered and the initial performance of 

Required Action A.1 must be complete within the first 8 hour interval. If 

Required Action A.1 is followed and the Required Action is not met within 

the Completion Time (plus the extension allowed by SR 3.0.2), 

Condition B is entered. If Required Action A.2 is followed and the 

Completion Time of 8 hours is not met, Condition B is entered.

If after entry into Condition B, Required Action A.1 or A.2 is met, 

Condition B is exited and operation may then continue in Condition A.

If after Condition A is entered, Required Action A.1 is not met within either 

the initial 1 hour or any subsequent 8 hour interval from the previous 

performance (plus the extension allowed by SR 3.0.2), Condition B is 

entered. The Completion Time clock for Condition A does not stop after 

Condition B is entered, but continues from the time Condition A was 

initially entered. If Required Action A.1 is met after Condition B is 

entered, Condition B is exited and operation may continue in accordance 

with Condition A, provided the Completion Time for Required Action A.2 

has not expired.

Frequency

General Electric BWR/4 STS 1.4-1 Rev. 4.0

1.0 USE AND APPLICATION

1.4 Frequency

PURPOSE The purpose of this section is to define the proper use and application of 

Frequency requirements.

DESCRIPTION Each Surveillance Requirement (SR) has a specified Frequency in which 

the Surveillance must be met in order to meet the associated LCO. An 

understanding of the correct application of the specified Frequency is 

necessary for compliance with the SR.

The "specified Frequency" is referred to throughout this section and each 

of the Specifications of Section 3.0.2, Surveillance Requirement (SR) 

Applicability. The "specified Frequency" consists of the requirements of 

the Frequency column of each SR as well as certain Notes in the 

Surveillance column that modify performance requirements.

Sometimes special situations dictate when the requirements of a 

Surveillance are to be met. They are "otherwise stated" conditions 

allowed by SR 3.0.1. They may be stated as clarifying Notes in the 

Surveillance, as part of the Surveillance, or both.

Situations where a Surveillance could be required (i.e., its Frequency 

could expire), but where it is not possible or not desired that it be 

performed until sometime after the associated LCO is within its 

Applicability, represent potential SR 3.0.4 conflicts. To avoid these 

conflicts, the SR (i.e., the Surveillance or the Frequency) is stated such 

that it is only "required" when it can be and should be performed. With an 

SR satisfied, SR 3.0.4 imposes no restriction.

The use of "met" or "performed" in these instances conveys specific 

meanings. A Surveillance is "met" only when the acceptance criteria are 

satisfied. Known failure of the requirements of a Surveillance, even 

without a Surveillance specifically being "performed," constitutes a 

Surveillance not "met." "Performance" refers only to the requirement to 

specifically determine the ability to meet the acceptance criteria. 

Some Surveillances contain notes that modify the Frequency of 

performance or the conditions during which the acceptance criteria must 

be satisfied. For these Surveillances, the MODE-entry restrictions of 

SR 3.0.4 may not apply. Such a Surveillance is not required to be 

performed prior to entering a MODE or other specified condition in the 

Applicability of the associated LCO if any of the following three conditions 

are satisfied:
Frequency

1.4

General Electric BWR/4 STS 1.4-2 Rev. 4.0

1.4 Frequency

DESCRIPTION (continued)

a. The Surveillance is not required to be met in the MODE or other 

specified condition to be entered; or

b. The Surveillance is required to be met in the MODE or other 

specified condition to be entered, but has been performed within the 

specified Frequency (i.e., it is current) and is known not to be failed; 

or

c. The Surveillance is required to be met, but not performed, in the 

MODE or other specified condition to be entered, and is known not 

to be failed.

Examples 1.4-3, 1.4-4, 1.4-5, and 1.4-6 discuss these special situations.

EXAMPLES The following examples illustrate the various ways that Frequencies are 

specified. In these examples, the Applicability of the LCO (LCO not 

shown) is MODES 1, 2, and 3.

EXAMPLE 1.4-1

SURVEILLANCE REQUIREMENTS

SURVEILLANCE FREQUENCY

Perform CHANNEL CHECK. 12 hours

Example 1.4-1 contains the type of SR most often encountered in the 

Technical Specifications (TS). The Frequency specifies an interval 

(12 hours) during which the associated Surveillance must be performed at 

least one time. Performance of the Surveillance initiates the subsequent 

interval. Although the Frequency is stated as 12 hours, an extension of 

the time interval to 1.25 times the interval specified in the Frequency is 

allowed by SR 3.0.2 for operational flexibility. The measurement of this 

interval continues at all times, even when the SR is not required to be met 

per SR 3.0.1 (such as when the equipment is inoperable, a variable is 

outside specified limits, or the unit is outside the Applicability of the LCO). 

If the interval specified by SR 3.0.2 is exceeded while the unit is in a 

MODE or other specified condition in the Applicability of the LCO, and the 

performance of the Surveillance is not otherwise modified (refer to 

Examples 1.4-3 and 1.4-4), then SR 3.0.3 becomes applicable.

1.4 Frequency

EXAMPLES (continued)

If the interval as specified by SR 3.0.2 is exceeded while the unit is not in 

a MODE or other specified condition in the Applicability of the LCO for 

which performance of the SR is required, then SR 3.0.4 becomes 

applicable. The Surveillance must be performed within the Frequency 

requirements of SR 3.0.2, as modified by SR 3.0.3, prior to entry into the 

MODE or other specified condition or the LCO is considered not met (in 

accordance with SR 3.0.1) and LCO 3.0.4 becomes applicable.

EXAMPLE 1.4-2

SURVEILLANCE REQUIREMENTS

SURVEILLANCE FREQUENCY

Verify flow is within limits. Once within 

12 hours after 

 25% RTP

AND

24 hours thereafter

Example 1.4-2 has two Frequencies. The first is a one time performance 

Frequency, and the second is of the type shown in Example 1.4-1. The 

logical connector "AND" indicates that both Frequency requirements must 

be met. Each time reactor power is increased from a power level 

< 25% RTP to  25% RTP, the Surveillance must be performed within 

12 hours.

The use of "once" indicates a single performance will satisfy the specified 

Frequency (assuming no other Frequencies are connected by "AND"). 

This type of Frequency does not qualify for the 25% extension allowed by 

SR 3.0.2. "Thereafter" indicates future performances must be established 

per SR 3.0.2, but only after a specified condition is first met (i.e., the 

"once" performance in this example). If reactor power decreases to 

< 25% RTP, the measurement of both intervals stops. New intervals start 

upon reactor power reaching 25% RTP.

construed to be part of the "specified Frequency." Should the 7 day 

interval be exceeded while operation is < 25% RTP, this Note allows 

12 hours after power reaches  25% RTP to perform the Surveillance. 

The Surveillance is still considered to be within the "specified Frequency." 

Therefore, if the Surveillance were not performed within the 7 day interval 

(plus the extension allowed by SR 3.0.2), but operation was < 25% RTP, 

it would not constitute a failure of the SR or failure to meet the LCO. 

Also, no violation of SR 3.0.4 occurs when changing MODES, even with 

the 7 day Frequency not met, provided operation does not exceed 

12 hours (plus the extension allowed by SR 3.0.2) with power 

 25% RTP.

Once the unit reaches 25% RTP, 12 hours would be allowed for 

completing the Surveillance. If the Surveillance were not performed 

within this 12 hour interval (plus the extension allowed by SR 3.0.2), there 

would then be a failure to perform a Surveillance within the specified 

Frequency, and the provisions of SR 3.0.3 would apply.

Example 1.4-4 specifies that the requirements of this Surveillance do not 

have to be met until the unit is in MODE 1. The interval measurement for 

the Frequency of this Surveillance continues at all times, as described in 

Example 1.4-1. However, the Note constitutes an "otherwise stated" 

exception to the Applicability of this Surveillance. Therefore, if the 

Surveillance were not performed within the 24 hour interval (plus the 

extension allowed by SR 3.0.2), but the unit was not in MODE 1, there 

would be no failure of the SR nor failure to meet the LCO. Therefore, no 

violation of SR 3.0.4 occurs when changing MODES, even with the 

24 hour Frequency exceeded, provided the MODE change was not made 

into MODE 1. Prior to entering MODE 1 (assuming again that the 24 hour

EXAMPLES (continued)

As the Note modifies the required performance of the Surveillance, the 

Note is construed to be part of the "specified Frequency." Should the 

7 day interval be exceeded while operation is not in MODE 1, this Note 

allows entry into and operation in MODES 2 and 3 to perform the 

Surveillance. The Surveillance is still considered to be performed within 

the "specified Frequency" if completed prior to entering MODE 1. 

Therefore, if the Surveillance were not performed within the 7 day (plus 

the extension allowed by SR 3.0.2) interval, but operation was not in 

MODE 1, it would not constitute a failure of the SR or failure to meet the 

LCO. Also, no violation of SR 3.0.4 occurs when changing MODES, even 

with the 7 day Frequency not met, provided operation does not result in 

entry into MODE 1.

Once the unit reaches MODE 1, the requirement for the Surveillance to 

be performed within its specified Frequency applies and would require 

that the Surveillance had been performed. If the Surveillance were not 

performed prior to entering MODE 1, there would then be a failure to 

perform a Surveillance within the specified Frequency, and the provisions 

of SR 3.0.3 would apply.

for the Frequency of this Surveillance continues at all times, as described 

in Example 1.4-1. However, the Note constitutes an "otherwise stated" 

exception to the Applicability of this Surveillance. Therefore, if the 

Surveillance were not performed within the 24 hour interval (plus the 

extension allowed by SR 3.0.2), and the unit was in MODE 3, there would 

be no failure of the SR nor failure to meet the LCO. Therefore, no

SR Applicability

3.0

General Electric BWR/4 STS 3.0-4 Rev. 4.0

3.0 SURVEILLANCE REQUIREMENT (SR) APPLICABILITY

SR 3.0.1 SRs shall be met during the MODES or other specified conditions in the 

Applicability for individual LCOs, unless otherwise stated in the SR. 

Failure to meet a Surveillance, whether such failure is experienced during 

the performance of the Surveillance or between performances of the 

Surveillance, shall be failure to meet the LCO. Failure to perform a 

Surveillance within the specified Frequency shall be failure to meet the 

LCO except as provided in SR 3.0.3. Surveillances do not have to be 

performed on inoperable equipment or variables outside specified limits.

SR 3.0.2 The specified Frequency for each SR is met if the Surveillance is 

performed within 1.25 times the interval specified in the Frequency, as 

measured from the previous performance or as measured from the time a 

specified condition of the Frequency is met.

For Frequencies specified as "once," the above interval extension does 

not apply.

If a Completion Time requires periodic performance on a "once per . . ." 

basis, the above Frequency extension applies to each performance after 

the initial performance.

Exceptions to this Specification are stated in the individual Specifications.

SR 3.0.3 If it is discovered that a Surveillance was not performed within its 

specified Frequency, then compliance with the requirement to declare the 

LCO not met may be delayed, from the time of discovery, up to 24 hours 

or up to the limit of the specified Frequency, whichever is greater. This 

delay period is permitted to allow performance of the Surveillance. A risk 

evaluation shall be performed for any Surveillance delayed greater than 

24 hours and the risk impact shall be managed.

If the Surveillance is not performed within the delay period, the LCO must 

immediately be declared not met, and the applicable Condition(s) must be 

entered.

When the Surveillance is performed within the delay period and the 

Surveillance is not met, the LCO must immediately be declared not met, 

and the applicable Condition(s) must be entered.

SR 3.0.4 Entry into a MODE or other specified condition in the Applicability of an 

LCO shall only be made when the LCO's Surveillances have been met 

within their specified Frequency, except as provided by SR 3.0.3. When 

an LCO is not met due to Surveillances not having been met, entry into a

----------------------------------------REVIEWER'S NOTE----------------------------------------

The use of any standard other than ASTM D3803-1989 to test the charcoal 

sample may result in an overestimation of the capability of the charcoal to adsorb 

radioiodine. As a result, the ability of the charcoal filters to perform in a manner 

consistent with the licensing basis for the facility is indeterminate.

ASTM D 3803-1989 is a more stringent testing standard because it does not 

differentiate between used and new charcoal, it has a longer equilibration period 

performed at a temperature of 30C (86F) and a relative humidity (RH) of 95% 

(or 70% RH with humidity control), and it has more stringent tolerances that 

improve repeatability of the test.

5.5.12 Safety Function Determination Program (SFDP)

This program ensures loss of safety function is detected and appropriate actions 

taken. Upon entry into LCO 3.0.6, an evaluation shall be made to determine if 

loss of safety function exists. Additionally, other appropriate actions may be 

taken as a result of the support system inoperability and corresponding exception 

to entering supported system Condition and Required Actions. This program 

implements the requirements of LCO 3.0.6. The SFDP shall contain the 

following:
Programs and Manuals

5.5

General Electric BWR/4 STS 5.5-10 Rev. 4.0

5.5 Programs and Manuals

5.5.12 Safety Function Determination Program (continued)

a. Provisions for cross train checks to ensure a loss of the capability to 

perform the safety function assumed in the accident analysis does not go 

undetected,

b. Provisions for ensuring the plant is maintained in a safe condition if a loss 

of function condition exists,

c. Provisions to ensure that an inoperable supported system's Completion 

Time is not inappropriately extended as a result of multiple support system 

inoperabilities, and

d. Other appropriate limitations and remedial or compensatory actions.

A loss of safety function exists when, assuming no concurrent single failure, no 

concurrent loss of offsite power, or no concurrent loss of onsite diesel 

generator(s), a safety function assumed in the accident analysis cannot be 

performed. For the purpose of this program, a loss of safety function may exist 

when a support system is inoperable, and:

a. A required system redundant to the system(s) supported by the inoperable 

support system is also inoperable,

b. A required system redundant to the system(s) in turn supported by the 

inoperable supported system is also inoperable, or

c. A required system redundant to the support system(s) for the supported 

systems (a) and (b) above is also inoperable.

The SFDP identifies where a loss of safety function exists. If a loss of safety 

function is determined to exist by this program, the appropriate Conditions and 

Required Actions of the LCO in which the loss of safety function exists are 

required to be entered. When a loss of safety function is caused by the 

inoperability of a single Technical Specification support system, the appropriate 

Conditions and Required Actions to enter are those of the support system.

2. If the as-found value of the instrument channel trip setting differs from 

the previous as-left value or the specified [LTSP or NTSP] by more 

than the pre-defined test acceptance criteria band (i.e., the specified 

AFT), then the instrument channel shall be evaluated before declaring 

the SR met and returning the instrument channel to service. This 

condition shall be entered in the plant corrective action program.

6. The minimum temperature requirements of Appendix G to 10 CFR Part 50 

shall be incorporated into the pressure and temperature limit curves.

7. Licensees who have removed two or more capsules should compare for 

each surveillance material the measured increase in reference temperature 

(RTNDT) to the predicted increase in RTNDT; where the predicted increase in 

RTNDT is based on the mean shift in RTNDT plus the two standard deviation 

value (2) specified in Regulatory Guide 1.99, Revision 2. If the measured 

value exceeds the predicted value (increase RTNDT + 2), the licensee 

should provide a supplement to the PTLR to demonstrate how the results 

affect the approved methodology.

5.6.5 Post Accident Monitoring Report

When a report is required by Condition B or F of LCO 3.3.[3.1], "Post Accident 

Monitoring (PAM) Instrumentation," a report shall be submitted within the 

following 14 days. The report shall outline the preplanned alternate method of 

monitoring, the cause of the inoperability, and the plans and schedule for 

restoring the instrumentation channels of the Function to OPERABLE status.

----------------------------------------REVIEWER'S NOTE----------------------------------------

These reports may be required covering inspection, test, and maintenance 

activities. These reports are determined on an individual basis for each unit and 

their preparation and submittal are designated in the Technical Specifications.

As provided in paragraph 20.1601(c) of 10 CFR Part 20, the following controls shall be applied 

to high radiation areas in place of the controls required by paragraph 20.1601(a) and (b) of 

10 CFR Part 20:

5.7.1 High Radiation Areas with Dose Rates Not Exceeding 1.0 rem/hour at 30 

Centimeters from the Radiation Source or from any Surface Penetrated by the 

Radiation

a. Each entryway to such an area shall be barricaded and conspicuously 

posted as a high radiation area. Such barricades may be opened as 

necessary to permit entry or exit of personnel or equipment.

b. Access to, and activities in, each such area shall be controlled by means of 

Radiation Work Permit (RWP) or equivalent that includes specification of 

radiation dose rates in the immediate work area(s) and other appropriate 

radiation protection equipment and measures.

c. Individuals qualified in radiation protection procedures and personnel 

continuously escorted by such individuals may be exempted from the 

requirement for an RWP or equivalent while performing their assigned 

duties provided that they are otherwise following plant radiation protection 

procedures for entry to, exit from, and work in such areas.

d. Each individual or group entering such an area shall possess:

1. A radiation monitoring device that continuously displays radiation 

dose rates in the area, or

2. A radiation monitoring device that continuously integrates the 

radiation dose rates in the area and alarms when the device's dose 

alarm setpoint is reached, with an appropriate alarm setpoint, or

3. A radiation monitoring device that continuously transmits dose rate 

and cumulative dose information to a remote receiver monitored by 

radiation protection personnel responsible for controlling personnel 

radiation exposure within the area, or

4. A self-reading dosimeter (e.g., pocket ionization chamber or electronic 

dosimeter) and,

(i) Be under the surveillance, as specified in the RWP or 

equivalent, while in the area, of an individual qualified in 

radiation protection procedures, equipped with a radiation 

monitoring device that continuously displays radiation does 

rates in the area; who is responsible for controlling personnel 

exposure within the area, or

(ii) Be under the surveillance, as specified in the RWP or 

equivalent, while in the area, by means of closed circuit 

television, of personnel qualified in radiation protection 

procedures, responsible for controlling personnel radiation 

exposure in the area, and with the means to communicate with 

individuals in the area who are covered by such surveillance.

e. Except for individuals qualified in radiation protection procedures, or 

personnel continuously escorted by such individuals, entry into such areas 

shall be made only after dose rates in the area have been determined and 

entry personnel are knowledgeable of them. These continuously escorted 

personnel will receive a pre-job briefing prior to entry into such areas. This 

dose rate determination, knowledge, and pre-job briefing does not require 

documentation prior to initial entry.
