SUBJECT: USE OF TRADITIONAL ENFORCEMENT FOR THE BROWNS FERRY

NUCLEAR PLANT, UNIT 1 RESTART

PURPOSE:

The purpose of this paper is to inform the Commission of the staff’s intent to apply traditional

enforcement during the restart process for Browns Ferry Nuclear Plant, Unit 1 (BFN1). The

staff does not plan to use the Reactor Oversight Process (ROP) for inspection and oversight of

BFN1 during the extended process now underway to return the unit to operation. The ROP

generally prescribes staff responses based on increases in public health and safety risk due to

core damage accident probability. The unique circumstances involved with the defueled BFN1

make the application of the ROP problematic until the unit returns to power operations. In the

interim, the staff proposes to use “traditional enforcement” to determine the significance of

violations involving reactor safety, and the resultant enforcement actions, instead of the

Significance Determination Process (SDP).

BACKGROUND:

Browns Ferry Units 1, 2, and 3 were voluntarily shut down in March 1985 for management and

regulatory issues. The Tennessee Valley Authority (TVA) submitted its Nuclear Performance

Plan, Volume 3, in August 1986, outlining the steps needed to obtain the Nuclear Regulatory

Commission’s (NRC) approval to restart each of the Browns Ferry units. The Browns Ferry

Units 2 and 3 were restarted in the 1990s prior to the implementation of the ROP. In May

of 2002, the licensee commenced a 5-year program to restart BFN1. Due to the extensive

modifications and upgrades required for BFN1, the staff developed a new inspection manual

chapter to govern the inspection of BFN1 restart activities and its transition to the ROP. The

staff has also determined that “traditional enforcement,” similar to the enforcement employed

during the BF2 and BF3 restarts, would be more appropriate for all violations identified during

BFN1's restart, as evidenced by its successful application during these previous restarts. 

DISCUSSION:

A. Bases for not Initially Applying the ROP During BFN1’s Restart

The ROP, which is governed by Inspection Manual Chapter (IMC) 2515, “Light-Water Reactor

Inspection Program,” IMC 0608, “Performance Indicator Program,” IMC 0609, “Significance

Determination Process,” IMC 0305, “Operating Reactor Assessment Program,” and the

Commission’s current Enforcement Policy, is not initially appropriate for the staff to use to

monitor BFN1 during its restart for the following reasons.

First, the inspection program described in IMC 2515 assumes that a licensed nuclear facility is

capable of operating safely within currently required safety margins. That assumption is not

valid for BFN1 because it is more comparable to a plant under construction than an operating

plant. Since its shutdown in March 1985, the reactor for BFN1 has been defueled, systems

have not operated and have generally been maintained in a lay up condition. In addition,

outstanding licensing actions and regulatory requirements have not been fully incorporated into

the design basis. Since BFN1 is currently not yet in full compliance with the regulations for

power operations, IMC 2515 is not currently applicable to BFN1. 

Second, the performance indicator (PI) program described in IMC 0608 applies to all operating

commercial nuclear power reactors. In preparation for the start of the implementation of the

ROP, licensees were requested to submit historical PI data on January 21, 2000. That

information was not submitted for BFN1. Since BFN1 has not operated for 18 years and any PI

data that old, if it exists, would not be valid for the intended purpose under the ROP, IMC 0608

is not currently applicable to BFN1.

Third, the SDP is used to evaluate inspection findings to determine their safety significance.

Each of the cornerstones or key strategic performance areas has one or more SDPs. The

SDPs for reactor safety in IMC 0609 are designed to provide a risk-informed framework to

estimate an actual increase in core damage frequency (CDF) and/or large early release

frequency (LERF) during at-power operations. Currently, BFN1 is defueled and, therefore, 

inspection findings associated with reactor safety for the initiating events, mitigating systems,

and barrier integrity cornerstones cannot represent an increase in these incremental risks. 

However, the other SDPs (i.e., for emergency preparedness (EP), radiation protection (RP),

etc.) may still be applied to findings within their respective cornerstones, when such

cornerstones are considered adequately monitorable and appropriate for using ROP baseline

inspections and performance indicators.

Fourth, the purpose of IMC 0305 is to enable the NRC to annually assess a licensee’s safety

performance based on information collected from baseline inspections and PIs. The Action

Matrix in this manual chapter is then used to determine a graded regulatory response based

upon safety significance. Given that PI and SDP inputs would not be available for all the

cornerstones, IMC 0305 cannot be used to determine a licensee’s overall performance. Since

complete information on the licensee’s performance would not be available for all the

cornerstones, the Action Matrix would provide inconclusive results. Therefore, the requisite

regulatory response would have to be based on staff review/evaluation and not the Action

Matrix. Under the ROP there is no other recourse than the Action Matrix for initiating the

appropriate regulatory response without taking a deviation. The latter would not be an efficient

means of dealing with inspection findings since each staff response to a significant finding

would require a deviation from the ROP.

B. Bases for Departure from the Commission’s Current Enforcement Policy for Browns Ferry 1

The General Statement of Policy and Procedure for NRC Enforcement Actions, NUREG-1600

(The Enforcement Policy), specifies that for certain types of violations at commercial nuclear

power plants, the NRC relies on information from the SDP. The only violation types whose full

significance cannot be evaluated via the SDP (the SDP exceptions) are those involving

willfulness (including discrimination), those impacting the NRC’s ability for oversight of licensed

activities, and those involving actual radiological consequences. Absent its unique situation the

significance of violations identified at BFN1 would be expected to be evaluated via the SDP

because BFN1 has maintained an operating license and is, therefore, classified as a

commercial nuclear power plant.

Nonetheless, at present there is no reactor-safety SDP available to determine the significance

of violations that occur during an extended defueled shutdown or during the construction or

extensive modification of a nuclear plant. The ROP is specifically intended and designed for

application at operating plants because of the readily apparent risks associated with nuclear

plant operation. All the ROP provisions associated with reactor safety, including data gathering,

collection, and assessment, are focused on the performance of a plant during operation. 

Because of the present need for a means to categorize the significance of violations identified

during the restart of BFN1, the staff concludes that a customized revision to the ROP, including

the development of such an SDP, would be neither timely nor a prudent action to take.

Therefore, until the staff determines that BFN1 is totally monitorable under the ROP, an

alternative approach is needed to assess the significance of violations and determine

appropriate enforcement actions and appropriate regulatory response. “Traditional

enforcement” is the best candidate for an alternative approach since it is currently available and

in use by the staff for a variety of other licensees, and has been routinely utilized at commercial

nuclear power plants for the SDP exceptions, noted above. Further, Supplement II to the

Enforcement Policy, Part 50 Facility Construction, has been retained and may be appropriate

for determining the significance of some violations at BFN1 due to the nature of the activities

planned during preparations for restart, i.e., major upgrades and modifications more

comparable to “construction” than to routine operations.

SUMMARY:

The staff intends to make a temporary departure from the current Enforcement Policy in the

case of BFN1. This departure will entail not initially using the SDP for the determination of the

significance of violations at BFN1 during the restart process but, rather, using the “traditional

enforcement” provisions of the Enforcement Policy, including the appropriate Supplements

(e.g., Supplement II). Since it is the intent of the new manual chapter for the BFN1 inspection

program that ROP baseline inspections, SDP, and review of PI data be applied on a

cornerstone-by-cornerstone basis as specific cornerstones become monitorable by the ROP,

traditional enforcement will only be utilized for a given cornerstone until such time that the staff 

places that cornerstone under the ROP baseline inspection, SDP, and PIs. Once all

cornerstones are monitorable by the ROP, BFN1 will transition to the full oversight of the ROP

and the Action Matrix will govern agency response to licensee performance at Unit 1. 

RESOURCES:

Resources have been budgeted for FY 2003 in the Office of Nuclear Reactor Regulation (NRR)

to support this task. Resources have also been included in the budget requests for FY 2004

through FY 2006 to support the task for those years. No additional resources are required.

COORDINATION:

The Office of the Chief Financial Officer has reviewed this paper and concurs.

The Office of the General Counsel has reviewed this paper and has no legal objection.
