STANDARD FORMAT AND CONTENT FOR

POST-SHUTDOWN DECOMMISSIONING ACTIVITIES REPORT

A. INTRODUCTION

Decommissioning means permanently removing a nuclear facility from service and reducing

radioactive materials on the licensee’s site to levels that would permit termination of the Nuclear

Regulatory Commission (NRC) license. On July 29, 1996, a final rule was published in the Federal

Register (61 FR 39278) amending the NRC's regulations on the decommissioning procedures that will

lead to termination of an operating license for nuclear power reactors. This rule included changes to

10 CFR Part 2, “Rules of Practice for Domestic Licensing Proceedings and Issuance of Orders”; Part 50,

“Domestic Licensing of Production and Utilization Facilities”; and Part 51, “Environmental Protection

Regulations for Domestic Licensing and Related Regulatory Functions.”

The regulation, in 10 CFR 50.82(a)(4)(i), requires the licensee, prior to or within 2 years of

permanent cessation of operations, to provide the NRC with a post-shutdown decommissioning activities

report (PSDAR). The PSDAR must include a description of the licensee's planned decommissioning

activities, a schedule for the accomplishment of significant milestones, and an estimate of expected costs.

The PSDAR should also document the results of the licensee's evaluation of the environmental impacts

associated with site-specific decommissioning activities. The evaluation should include a comparison of

the site-specific environmental impacts of the proposed decommissioning with those impacts identified in

previously issued environmental statements, the generic environmental impact statement on

decommissioning, “Final Generic Environmental Impact Statement (GEIS) on Decommissioning of
1.185-2

Nuclear Facilities” (NUREG-0586, Ref. 1), and the GEIS, “Generic Environmental Impact

Statement in Support of Rulemaking on Radiological Criteria for License Termination of NRC

Licensed Nuclear Facilities” (NUREG-1496, Ref. 2).

The purpose of the PSDAR is to provide the NRC and the public with a general overview

of the licensee's proposed decommissioning activities. The PSDAR serves to inform the NRC

staff of the licensee’s expected activities and schedule, facilitating planning for inspections and

decisions regarding NRC oversight activities. The PSDAR is also a mechanism for informing the

public of the proposed decommissioning activities before the decommissioning activities are

conducted.

The purpose of this regulatory guide is to identify the type of information to be contained

in the PSDAR and establish a standard format for the PSDAR that is acceptable to the NRC staff.

The NRC staff suggests that licensees use this standard format to facilitate the preparation of

PSDARs. This regulatory guide is being developed and issued in conjunction with Regulatory

Guide 1.184, “Decommissioning of Nuclear Power Reactors” (Ref. 3), which is also in support of

the decommissioning rule (61 FR 39278).

The information collections contained in this regulatory guide are covered by the

requirements of 10 CFR Part 50, which were approved by the Office of Management and Budget,

approval number 3150-0011. If a means used to impose an information collection does not

display a currently valid OMB control number, the NRC may not conduct or sponsor, and a person

is not required to respond to, the information collection.

B. DISCUSSION

According to 10 CFR 50.82(a)(5), the licensee is prohibited from performing any major

decommissioning activities until 90 days after the NRC has received the licensee's PSDAR

submission and until the certifications of permanent cessation of operations and permanent

removal of fuel from the reactor vessel have been submitted. Major decommissioning activities

are defined in 10 CFR 50.2 as "any activity that results in permanent removal of major radioactive

compo-nents, permanently modifies the structure of the containment, or results in dismantling

components for shipment containing greater than class C waste . . . ." Major radioactive

components are defined in 10 CFR 50.2 as “the reactor vessel and internals, steam generators,

pressurizers, large bore reactor coolant system piping, and other large components that are

radioactive to a comparable degree.”

Upon receipt of the PSDAR, the NRC will docket the PSDAR and place a notice regarding

its receipt in the Federal Register to solicit comments on the PSDAR from the public pursuant to

10 CFR 50.82(a)(4)(ii). A copy of the PSDAR will be made available to the public at the Public

Document Room and electronically through the Electronic Reading Room at the NRC’s web site,

<WWW.NRC.GOV>. The NRC will schedule a public meeting in the vicinity of the site to

describe planned activities and to hear public comments. Comments received by the NRC staff on

the PSDAR will be addressed at the public meeting, and a question and answer period will follow

the presentations. A written transcript of the meeting will be prepared and made available to the
1.185-3

public through the Public Document Room and electronically through the Electronic Reading

Room at the NRC’s web site, <WWW.NRC.GOV>. To the extent possible, the public meeting

should be held within 90 days of the NRC’s receipt of the licensee's PSDAR submittal; it

normally would be held about 30 days before the 90-day period ends.

The NRC will determine whether the licensee’s PSDAR contains the information required

by the regulation. Major decommissioning activities may not start until 90 days after the NRC

receives the PSDAR. Although NRC review and approval of the PSDAR is not required, if the

NRC determines that the information provided by the licensee in the PSDAR does not comply

with the requirements in 10 CFR 50.82(a)(4)(i), the NRC will inform the licensee in writing of the

additional information required by the regulations before the PSDAR public meeting and before

major decommissioning activities are begun. A list of factors that could cause the NRC to find

the PSDAR deficient are given in Section 5 of this guide.

The above provisions for PSDARs apply to licensees who did not have an NRC-approved

decommissioning plan by August 28, 1996, which was the effective date of the rule. For licensees

that have a decommissioning plan that was approved before August 28, 1996, the approved

decommissioning plan and the associated environmental review are considered to be the PSDAR

submittal (see 10 CFR 50.82). Decommissioning plans normally contain sufficient information to

satisfy the requirements of the PSDAR. If a licensee had submitted a decommissioning plan

before August 28, 1996, and the NRC staff had not taken final action on the plan, the staff deems

the decommissioning plan to be the PSDAR submittal. Licensees with an approved

decommissioning plan are required to submit an update to the PSDAR for activities that were not

considered in their decommissioning plan. Because of the amount of material contained in the

decommissioning plans and the requirement to update this information, and because of the

potential for a misunderstanding as to what must be updated, licensees are encouraged to replace

their decommissioning plans with a PSDAR update that uses the format and content specified in

this document.

C. FORMAT AND CONTENT OF THE POST-SHUTDOWN

DECOMMISSIONING ACTIVITIES REPORT

The purposes of the PSDAR are to (1) inform the public of the licensee’s planned

decommissioning activities, (2) assist in the scheduling of NRC resources necessary for the

appropriate oversight activities, (3) ensure the licensee has considered the costs of the planned

decommissioning activities and considered the funding for the decommissioning process, and (4)

ensure the environmental impacts of the planned decommissioning activities are bounded by those

considered in existing environmental impact statements.

Submission of the PSDAR must precede any major decommissioning activities as they are

defined in 10 CFR 50.2. The rule in 10 CFR 50.82(a)(4)(i) requires that the PSDAR include (1) a

description of the licensee's planned major decommissioning activities, (2) a schedule for

completing these activities, (3) an estimate of the expected decommissioning costs, and (4) a

discussion that provides the reasons for concluding that the environmental impacts associated with

site-specific decommissioning activities will be bounded by appropriate previously issued
1.185-4

environmental impact statements. Each of these items is discussed in further detail in the

following sections and the content expected by the NRC staff is described.

1. DESCRIPTION OF LICENSEE'S PLANNED DECOMMISSIONING ACTIVITIES

The PSDAR should include a description of the licensee's planned activities for

decommissioning. The purpose of the description is to inform the NRC and the public of the

planned decommissioning by providing a general overview of the proposed decommissioning

activities and identifying specific activities to be accomplished or performed.

The licensee should describe (in general terms) the method or combination of methods

selected for decommissioning (i.e., long-term storage followed by decontamination and

dismantlement (SAFSTOR), or prompt decontamination and dismantlement (DECON), or partial

decontamination and dismantlement followed by long-term storage and then final

decontamination and dismantlement). The licensee should also list and describe the major

activities and tasks related to decommissioning. The activities and tasks should be identified and

discussed briefly in the order in which they will occur. The level of detail of the description

provided for each of the activities will depend, in part, on the nature of the activity. Activities that

are specific and unique to the facility, and thus would require additional NRC staff oversight,

should be described in greater detail than routine activities. For example, a chemical

decontamination of a slightly radioactively contaminated system using a mild acid would require

only a short description of the process. However, it is expected that the use of a unique chemical

decontamination method on a system containing large amounts of contamination (for instance, the

primary system) would result in a more detailed description of the process for the staff to ascertain

the level of oversight that would be required. Likewise, an activity that could result in an

environmental impact that may be outside the bounds of those considered in the GEIS, such as the

removal, processing, and storage of fuel debris contained in a system or in the spent fuel pool,

would need to be discussed in greater detail.

The following are provided merely as examples and are not meant to be all inclusive or to

imply that a given licensee must include each of the activities in the decommissioning process.

The description of the licensee's planned decommissioning activities is meant to provide a

general, site-specific overview of all the activities occurring from the time of certification of

permanent removal of the fuel to the anticipated termination of the license.

For a prompt dismantlement, it is expected that activities such as the following would be

described:

 Removal of the reactor vessel and internals,

 Removal of other large components, including major radioactive components,

 Removal of the balance of the primary system (charging system, boron control system,

etc.),

 General activities related to the removal of other significant radioactive components and

any structures,

 Decontamination of radioactive components, including the use of chemical

decontamination techniques,
1.185-5

 Decontamination of structures or buildings, such as the auxiliary and fuel handling

buildings,

 Special or unusual programs (for instance, removal and processing of fuel debris from the

spent fuel pool) that might result in impacts that were not considered in the GEIS (these

activities would need to be described in greater detail),

 Onsite storage of components,

 Shipment and processing of the low-level radioactive waste, including any anticipated

compaction or incineration of the waste,

 Location (if known) of the ultimate disposal site for the low-level radioactive waste,

 Storage or removal of the spent fuel and greater-than-Class-C waste, including the use (if

planned) of an independent spent fuel storage installation (ISFSI) or wet storage facility,

 Removal of hazardous radioactive (mixed) wastes, and

 Changes in management and staffing.

If long-term storage (longer than approximately 5 years) is selected as a decommissioning

option, the activities related to preparing the facility and site for storage should be listed and

described. Activities and tasks for maintaining the facility and site in safe storage should also be

discussed. It is expected that the description of the preparation process and the storage phase

would specifically call out activities such as the following examples.

 Draining of specific systems and removal of resins from ion exchangers,

 Decontamination of specific high-dose areas,

 Removal of low-level waste that is ready to be shipped,

 Shipment and processing or storage of the fuel and greater-than-Class-C waste,

 De-energizing or deactivating specific systems,

 Reconfiguration of ventilation systems and fire protection systems for use during the

storage period,

 Inspection and monitoring plans during the storage period,

 Maintenance of any systems critical to final dismantlement during the storage period, and

 Changes in management and staffing.

The activities related to the transition from long-term storage to decommissioning and

activities related to the final decommissioning of the facility should also be described to the extent

known. According to 10 CFR 50.82(a)(3), decommissioning will be completed within 60 years of

permanent cessation of operation unless a longer term for completion is approved by the NRC as

necessary for public health and safety.

Details regarding the radiation protection plan, security plan, or discussions on quality

assurance (QA) related to decommissioning are not required or expected in the PSDAR; however,

this information may be required in periodic updates to the Final Safety Analysis Report.

2. SCHEDULE OF PLANNED DECOMMISSIONING ACTIVITIES

The purpose of the schedule is to provide information to the NRC and the public on the

anticipated timing of decommissioning events, as well as to allow the NRC to schedule resources

necessary for appropriate oversight activities. The relationship between the activities should be
1.185-6

shown for the major activities described in Section 1, so the reader understands the sequence of

events as well as the timing of the events.

Schedules or diagrams should clearly indicate the estimated initiation and completion of

the major decommissioning activities with potential increased risk to the workers, public, or

environment, or those that are unique to the facility. Any activities that will require a significant

NRC licensing effort should be identified, including the start and desired end dates for activities

such as the submission of defueled technical specifications, the approval and licensing of an

ISFSI, the licensing activities associated with a certificate of compliance for transportation of

major components, or the approval of the license termination plan. Changes to the schedule

following submission of the PSDAR are addressed in Section 6 of this guide, “Changes to the

PSDAR.”

The level of detail of the schedule will depend on the timing of the activity and will assist

the NRC in determining the degree of oversight required. The schedule for major activities in the

near term should be given to the nearest month and year. Activities that will follow a storage

period of at least 5 years may be scheduled to the closest year.

3. ESTIMATE OF EXPECTED DECOMMISSIONING COSTS

The PSDAR should include an updated estimate of the expected decommissioning costs.

The updated cost estimate required by 10 CFR 50.82(a)(4)(i) may be (1) the amount of

decommissioning funds estimated to be required pursuant to 10 CFR 50.75(b) and (c) as currently

reported on a calendar-year basis at least once every 2 years to the NRC according to 10 CFR

50.75(f)(1), (2) a site-specific cost estimate that is based on the activities and schedule discussed

in Sections 1 and 2 above, (3) an estimate based on actual costs at similar facilities that have

undergone similar decommissioning activities, or (4) a generic cost estimate. The licensee’s

decision on which type of estimate to include in the PSDAR should be based on specific plans for

decommissioning. If a licensee has chosen extended safe storage of the facility followed by

decontamination and dismantlement, generic information would be acceptable to the NRC staff as

cost estimates of final dismantlement could occur far in the future. The licensee is reminded that

a site-specific cost estimate is required within 2 years of permanently ceasing operation

(10 CFR 50.82(a)(8)(iii)). The licensee may consider submitting site-specific cost estimate data in

the PSDAR if it is planning immediate decontamination and dismantlement and is planning to

spend more than 23 percent of the decommissioning funds.

For generic cost estimate methods, see NUREG/CR-0672 (including Addenda 1 through

4), “Technology, Safety and Costs of Decommissioning a Reference Boiling Water Reactor Power

Station” (Ref. 4); NUREG/CR-0130, “Technology, Safety and Costs of Decommissioning a

Reference Pressurized Water Reactor Power Station” (Ref. 5); NUREG/CR-5884, “Revised

Analysis of Decommissioning for the Reference Pressurized Water Reactor Power Station” (Ref.

6); NUREG/CR-6174, “Revised Analyses of Decommissioning for the Reference Boiling Water

Reactor Power Station” (Ref. 7); and NUREG-0586, “Final Generic Environmental Impact

Statement on Decommissioning of Nuclear Facilities” (Ref. 1).
1.185-7

The cost estimate presented in the PSDAR could be a combination of any of these or other

methods, but the amount estimated cannot be less than the amount estimated by the method in 10

CFR 50.75(c). If the cost estimate is less than the amount estimated by the method in 10 CFR

50.75(c), the PSDAR would be considered to be deficient. Also, in accordance with 10 CFR

50.75(b)(2), the licensee must annually adjust the minimum amounts required by 10 CFR

50.75(c)(2).

Following the submission of the site-specific cost estimate that is required by 10 CFR

50.82(a)(8)(iii), if the licensee’s PSDAR specifies delayed completion of decommissioning, the

licensee must provide a means of adjusting cost estimates and associated funding levels over the

duration of the storage or surveillance period to ensure that the appropriate amount of funding will

be available to terminate the license [see 10 CFR 50.82(a)(8)(iv)]. That mechanism should be

described in the PSDAR. If the licensee has submitted a site-specific estimate as required by 10

CFR 50.82(a)(8)(iii), the means of adjusting the cost estimates should be described in the cost

section of the PSDAR as well as in the site-specific cost estimate.

Additional regulatory guidance on cost estimates is being developed and will be provided

in a regulatory guide.

4. ENVIRONMENTAL IMPACTS

The PSDAR should include a discussion of the reasons for concluding that the

environmen-tal impacts associated with site-specific decommissioning activities will be bounded

by previously issued environmental impact statements. Prior to preparing the PSDAR, the

licensee should evaluate the potential environmental impacts associated with the site-specific

decommissioning activities, including those activities listed in Section 1 of this guide. The

potential environmental impacts associated with decommissioning should be compared with

similar impacts given in the Final Environmental Statement (FES) for the plant (as supplemented),

in the GEIS on decommis-sioning (NUREG-0586) (Ref. 1), site-specific environmental

assessments, and the GEIS on radiological criteria for license termination (NUREG-1496) (Ref.

2). The comparison with impacts in the GEIS should recognize the unique nature of the site. If

the postulated impacts associated with decommissioning have already been considered in the

plant-specific FES as supple-mented, or the GEIS, the licensee should state this in the PSDAR

[see 10 CFR 50.82(a)(4)(i)]. An analysis of the specific environmental impacts associated with

decommissioning activities need not be included in the PSDAR. For those activities determined

to have impacts greater than those evaluated in the GEIS, FES, site-specific analysis, or

NUREG-1496, a supplement to these documents must be completed prior to the initiation of the

activities. The analysis of the specific environmental impacts associated with decommissioning

activities need not be included in the PSDAR; however, supporting documentation and analyses

must be available at the reactor site for inspection by the NRC staff.

Potential impacts include both radiological and nonradiological impacts. Examples of

potential impacts that should be examined to ensure they are within the envelope of impacts

predicted in the GEISs on decommissioning or radiological criteria for license termination, FES,

or site-specific analysis include occupational dose; environmental releases to air, water, and soil

and the resulting population doses; quantity of low-level radioactive waste generated;
1.185-8

transportation impacts; and impacts from nonradiological hazards such as dust, noise, water use,

and hazardous (nonradiological) waste. The licensee’s dose estimates should be for Total

Effective Dose Equivalent (TEDE). The licensee should briefly describe how these estimates of

TEDE compare to or are different from the GEIS or FES whole body and organ dose estimates.

Impacts to endangered and threatened species should be examined specifically. In many cases, the

list of endangered or threatened species has changed since the most recent FES; a current list

should be obtained from the appropriate U.S. Fish and Wildlife Service office. A determination

should be made as to the likelihood that a protected species is found on the site. If any species is

likely to be affected by the decommissioning of the facility, this potential should be identified in

the PSDAR.

Any planned decommissioning activity using a method not considered in the GEIS on

decommissioning (NUREG-0586, Ref. 1) could cause an environmental impact that has not been

considered and should be specifically examined. For example, the explosive destruction of

buildings that have not been decontaminated to levels that allowed their free release would likely

result in environmental impacts not considered in the GEIS or the site-specific FES.

If significant environmental impacts are identified that have not been considered in the

plant-specific FES or in the GEISs on decommissioning (Ref. 1) and on radiological criteria for

license termination (Ref. 2), the licensee is prohibited by 10 CFR 50.82(a)(6)(ii) from undertaking

the activity that would result in such an impact without first complying with 10 CFR Part 51. The

licensee must submit a supplement to its environmental report that relates to the additional

impacts under 10 CFR Part 51.

For plants that do not have an FES, an environmental assessment such as that prepared for

the change from a provisional operating license to a full-term operating license is appropriate.

5. FACTORS THAT COULD CAUSE THE NRC TO FIND THE PSDAR DEFICIENT

A number of factors could cause the NRC to find the PSDAR deficient. These factors are

directly related to the topics included in the PSDAR, as discussed above. The NRC could find the

PSDAR deficient in the following circumstances.

 The licensee’s plan for decommissioning could not be completed as described, for

example, if the plan called for immediate decontamination and dismantlement of the

facility and there were no waste disposal facilities available for the facility to use.

 The schedule included a decommissioning process that could not be completed within 60

years of the permanent cessation of operations as required by 10 CFR 50.82(a)(3), unless it

were shown that a longer decommissioning period is necessary to protect public health and

safety (if so, approval would be made on a case-by-case basis).

 The licensee’s decommissioning plans, as presented in the PSDAR, included a

decommissioning process that could not be completed for the estimated cost using the

generic guidelines in the GEIS and using previous facility decommissioning costs or if the

estimated costs were less than the amount estimated by the method in 10 CFR 50.75(c).
1.185-9

 The PSDAR included activities that would endanger the health and safety of the public by

proposing activities that do not comply with the NRC’s health and safety regulations or

would result in a significant detrimental impact to the environment that is not bounded by

the current environmental impact statements.

6. CHANGES TO THE PSDAR

According to 10 CFR 50.82(a)(7), the licensee must notify the NRC, in writing with a copy

to the affected States, before performing any significant decommissioning activity that could be

considered to be inconsistent with, or a significant schedule change from, the list of planned

decommissioning activities or schedules described in the PSDAR. Changes to the PSDAR may be

in the form of a written letter to NRC or may be an actual revision to the PSDAR. Changes that

result in any type of environmental impact not bounded by previously issued environmental impact

statements would need a supplement to the Environmental Report. The supplement should be

submitted to the NRC, with a copy sent to the affected States. Changes that significantly increase

the decommissioning costs also require notification to the NRC with a copy sent to the affected

States.

The PSDAR may be changed by the following process. Significant changes in major

schedules or the cost estimate require written notification to the NRC. Changes to the milestone

schedule will be used by the NRC staff to schedule NRC inspections of the licensee’s activities

and to provide assurance that decommissioning is being conducted safely and in accordance with

regulatory requirements. Examples of changes in activities and schedule include, but are not

limited to, changing from long-term storage to active dismantlement, changing the method used to

remove the reactor vessel or steam generators from cutting and segmenting to intact removal, or

changing the schedule to affect major milestones. Changes regarding the removal of structures,

systems, or components that do not pose a direct or indirect potential radiological hazard need not

be reported. Examples of significant increases in cost associated with decommissioning the

facility would include a new estimated cost greater than 20 percent above the site-specific cost

estimate or the PSDAR cost estimate, or a 25 percent increase in cost above a major milestone

estimate. The significant increase in cost would require written notification to the NRC.

Notification should be made only if cost changes occur as a result of changes in the timing of

activities or if planned decommissioning activities result in a significant increase in

decommissioning costs. Notification of increased decommissioning costs is not necessary if the

increases are simply because of higher estimated costs caused by inflation.

Changes in decommissioning activities should be evaluated as to their potential

environmental impact. If the expected impact is greater than that predicted in the GEIS or the

site-specific FES, or is outside the bounds of these documents, the licensee must notify the NRC in

writing and provide a supplement to the Environmental Report for the facility that evaluates the

impact of the change.

For facilities that either have an approved decommissioning plan or have submitted a

decommissioning plan before the effective date of the rule, August 28, 1996, the decommissioning

plan is deemed to be the PSDAR submittal according to 10 CFR 50.82. This is appropriate since
1.185-10

the decommissioning plan was required to contain all the information required by the PSDAR, but

in greater detail.

For facilities with approved decommissioning plans, decommissioning can proceed under

the associated decommissioning order. Significant changes in major milestones, schedules, or cost

estimates require written notification to the NRC. For facilities that submitted a decommissioning

plan for NRC approval prior to the issuance of the 1996 rule but the NRC had not yet approved

their plan, the 90-day period prior to initiation of major decommissioning activities began August

28, 1996.

Since the level of detail required in the PSDAR is significantly less than that required in

decommissioning plans, licensees who have submitted a decommissioning plan for approval or

licensees with an approved decommissioning plan are encouraged to extract the pertinent detail

from the decommissioning plan and submit a PSDAR update in the format and content specified

by this regulatory guide.

Written notifications to the NRC made under 10 CFR 50.82(a)(7) do not require a 90-day

waiting period prior to initiation of activities. Typically, the staff would not require a public

meeting to discuss the proposed changes. If, however, the licensee proposes changing the method

of decommissioning, for example, from long-term storage followed by decontamination and

dismantlement to prompt decontamination and dismantlement, a public meeting may be held.
