INSPECTION REPORT 05000456/2010503(DRS); 05000457/2010503(DRS)

AND NOTICE OF VIOLATION

Dear Mr. Pacilio:

On February 10, 2011, the U. S. Nuclear Regulatory Commission (NRC) completed an in-office

inspection of your Braidwood Station, Units 1 and 2. The purpose of the inspection was to

review the facts and circumstances concerning Unresolved Item 05000456/2009005-07;

05000457/2009005-07, Changes to Emergency Action Level HU6 Potentially Decrease the

Effectiveness of the Plans without Prior NRC Approval. The enclosed report documents the

inspection results, which were discussed by telephone on February 10, 2011, with

Mr. D. Enright and other members of your staff.

The inspection examined activities conducted under your license as they relate to safety and

compliance with the Commissions rules and regulations and with the conditions of your license.

The inspectors reviewed selected procedures and records, observed activities, and interviewed

personnel.

The report documents one NRC-identified finding of very low safety significance (Green). The

finding was determined to involve a violation of NRC requirements. Based on the results of the

inspection and following consultation with the NRC Office of Enforcement staff, we categorized

the violation at Severity Level IV. The violation was evaluated in accordance with the NRC

Enforcement Policy. The current Enforcement Policy is included on the NRC=s Web site at

(http://www.nrc.gov/about-nrc/regulatory/enforcement/enforce-pol.html).

The violation is cited in the enclosed Notice of Violation (NOV) and the circumstances

surrounding it are described in detail in the subject inspection report. The violation is being

cited in the Notice and a response is required because no corrective action had been taken to

restore compliance since the issue was entered in your corrective action program in

December 2009.

M. Pacilio -2-

You are required to respond to this letter and should follow the instructions specified in the

enclosed Notice when preparing your response. The NRC will use your response, in part, to

determine whether further enforcement action is necessary to ensure compliance with

regulatory requirements. In particular, the NRC is interested in any human performance issues

associated with performance of 10 CFR 50.54(q) reviews of Emergency Plan and Emergency

Action Level changes for all Exelon facilities.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter,

its enclosure, and your response, will be available electronically for public inspection in the NRC

Public Document Room or from the Publicly Available Records System (PARS) component of

NRC's Agencywide Documents Access and Management System (ADAMS), accessible from

Braidwood Station, Units 1 and 2 License Nos. NPF-72; NPF-77

EA-10-220

During a U. S. Nuclear Regulatory Commission (NRC or Commission) inspection completed on

February 10, 2011, a violation of NRC requirements was identified. In accordance with the NRC

Enforcement Policy, the violation is listed below:

Title 10 CFR 50.54(q) requires, in part, AA licensee authorized to possess and operate a

nuclear power reactor shall follow and maintain in effect emergency plans which meet

the standards in '50.47(b) and the requirements in Appendix E of this part. The

licensee may make changes to these plans without Commission approval only if the

changes do not decrease the effectiveness of the plans and the plans, as changed,

continue to meet the standards of '50.47(b) and the requirements of Appendix E.

Title 10 CFR 50.47(b)(4) requires, in part, A standard emergency classification and

action level scheme, the bases of which include facility system and effluent parameters,

is in use by the nuclear facility licensee, and State and local response plans call for

reliance on information provided by facility licensees for determinations of minimum

initial offsite response measures.@

Contrary to the above, as of March 28, 2008, the licensee made a change to its

emergency plan which decreased the effectiveness of the plan and caused the

emergency plan to no longer meet the standards of 50.47(b) and Appendix E to this part

without Commission approval. Specifically, the licensee modified the Emergency Action

Level (EAL) Basis in EAL HU6, Revision 21, to delay the 15-minute classification time by

the dispatching of personnel, reporting the notification of a fire from the field, and

extinguishing the fire. As a result, this change indefinitely extends the start of the

15-minute emergency classification clock beyond a credible notification that a fire is

occurring or indication of a valid fire detection system alarm. This change decreased the

effectiveness of the emergency plan by reducing the capability to perform a risk

significant planning function in a timely manner.

This is a Severity Level IV Violation (Section 6.6).

This violation is associated with a Green SDP finding.

Pursuant to the provisions of 10 CFR 2.201, Exelon Generation Company, LLC is hereby

required to submit a written statement or explanation to the U. S. Nuclear Regulatory

Commission, ATTN: Document Control Desk, Washington, DC 20555-0001 with a copy to the

Regional Administrator, Region III, and a copy to the NRC Resident Inspector at the Braidwood

facility, within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This

reply should be clearly marked as a Reply to a Notice of Violation; EA-10-220 and should

include for each violation: (1) the reason for the violation, or, if contested, the basis for disputing

the violation or severity level; (2) the corrective steps that have been taken and the results

achieved; (3) the corrective steps that will be taken; and (4) the date when full compliance will

be achieved. Your response may reference or include previous docketed correspondence, if

the correspondence adequately addresses the required response. If an adequate reply is not

Notice of Violation -2-

received within the time specified in this Notice, an Order or a Demand for Information may be

issued as to why the license should not be modified, suspended, or revoked, or why such other

action as may be proper should not be taken. Where good cause is shown, consideration will

be given to extending the response time.

If you contest this enforcement action, you should also provide a copy of your response, with

the basis for your denial, to the Director, Office of Enforcement, U. S. Nuclear Regulatory

Commission, Washington, DC 20555-0001.

Because your response will be made available electronically for public inspection in

the NRC Public Document Room or from the NRCs Agencywide Documents Access

and Management System (ADAMS), accessible from the NRC Web site at

http://www.nrc.gov/reading-rm/adams.html, to the extent possible, it should not include

any personal privacy, proprietary, or safeguards information so that it can be made available

to the public without redaction. If personal privacy or proprietary information is necessary to

provide an acceptable response, then please provide a bracketed copy of your response

that identifies the information that should be protected and a redacted copy of your response

that deletes such information. If you request withholding of such material, you must specifically

identify the portions of your response that you seek to have withheld and provide in detail the

bases for your claim of withholding (e.g., explain why the disclosure of information will create

an unwarranted invasion of personal privacy or provide the information required by

10 CFR 2.390(b) to support a request for withholding confidential commercial or financial

information). If safeguards information is necessary to provide an acceptable response, please

provide the level of protection described in 10 CFR 73.21.

In accordance with 10 CFR 19.11, you may be required to post this Notice within two working

days.

SUMMARY OF FINDINGS

Inspection Report (IR) 05000456/2010503(DRS), 05000457/2010503(DRS); 06/16/2010 -

02/10/2011; Braidwood Station, Units 1 and 2; results of U. S. Nuclear Regulatory Commission

(NRC) Emergency Action Level and Emergency Plan Changes Inspection and Follow-up of

Unresolved Item (URI)05000456/2009005-07; 05000457/2009005-07.

This report covers an approximate 6-month period of follow-up inspection and review of the

licensees emergency action level and plan changes. One Green finding was identified by the

inspector. The finding involved a Severity Level IV Cited Violation (NOV) of NRC regulations.

The significance of most findings is indicated by their color (Green, White, Yellow, Red) using

Inspection Manual Chapter (IMC) 0609, Significance Determination Process. Findings for

which the Significance Determination Process does not apply may be Green or be assigned a

severity level after NRC management review. The NRCs program for overseeing the safe

operation of commercial nuclear power reactors is described in NUREG-1649, Reactor

Oversight Process, Revision 4, dated December 2006.

A. NRC-Identified and Self-Revealed Findings

Cornerstone: Emergency Preparedness

  • Severity Level IV/Green. A Green finding involving a Severity Level IV, Cited Violation of

10 CFR 50.54(q) was identified by the inspector for the licensees change to the

emergency plan which decreased the effectiveness of the plan without NRC approval.

Specifically, the licensee modified the Emergency Action Level (EAL) Basis in EAL HU6,

Revision 21, to delay the 15-minute classification time by the dispatching of personnel,

reporting the notification of a fire from the field, and extinguishing the fire. As a result,

this change indefinitely extends the start of the 15-minute emergency classification clock

beyond a credible notification that a fire is occurring or indication of a valid fire detection

system alarm. This change decreased the effectiveness of the emergency plan by

reducing the capability to perform a risk significant planning function in a timely manner.

The violation affected the NRCs ability to perform its regulatory function because it

involved implementing a change that decreased the effectiveness of the emergency plan

without NRC Commission approval. Therefore, this issue was evaluated using

Traditional Enforcement. The NRC determined that a Severity Level IV violation was

appropriate due to the reduction of the capability to perform a risk significant planning

standard function in a timely manner. The violation is cited because no corrective action

had been taken to restore compliance since the issue was entered in the licensees

corrective action program in December 2009.

The performance deficiency was more than minor and of very low safety-significance

using Manual Chapter (MC) 0612 and MC 0609, Appendix B, because it is associated

with the emergency preparedness cornerstone attribute of procedure quality for EAL and

emergency plan changes, and it adversely affected the cornerstone objective of ensuring

that the licensee is capable of implementing adequate measures to protect the health

and safety of the public in the event of a radiological emergency. Therefore, the

performance deficiency was a finding. Using MC 0609, Appendix B, the inspector

determined that the finding had a very low safety significance. The inspectors also

determined that the finding had a cross-cutting aspect in the area of Human

Performance, decision-making because the licensee did not recognize that the change

.1 Emergency Action Level and Emergency Plan Changes

a. Inspection Scope

This inspection was a follow-up review of Unresolved Item (URI)05000456/2009005-07;

URI 05000457/2009005-07. The issue was identified in December 2009 during a routine

review of changes implemented to the Braidwood Station Emergency Plan Annex

Emergency Action Level (EAL) and EAL Basis. The inspector reviewed applicable

licensee documents and had discussions with licensee personnel.

b. Findings

Introduction:

A Green finding involving a Severity Level IV, Cited Violation of 10 CFR 50.54(q) was

identified by the inspector for the licensees change to the emergency plan which

decreased the effectiveness of the plan without U. S. Nuclear Regulatory Commission

(NRC) approval.

Description:

The Radiological Emergency Plan Annex for Braidwood Station, Revision 20, EAL HU6

provided the basis for declaring an Unusual Event due to a fire in the protected area not

extinguished within 15 minutes of detection. The EAL HU6 Basis, Revision 20, stated in

part: The 15-minute period begins with a credible notification that a fire is occurring or

indication of a valid fire detection system alarm. A verified alarm is assumed to be an

indication of a fire unless personnel dispatched to the scene disprove the alarm within

the 15-minute period. The report, however, shall not be required to verify the alarm.

On March 28, 2008, Braidwood Station staff implemented Revision 21 of the EAL HU6

Basis which added the following text: The 15-minute period to extinguish the fire begins

with a credible notification that a fire is occurring or indication of a valid fire detection

system alarm. If the alarm cannot be verified by redundant Control Room or nearby fire

panel indications, notification from the field that a fire exists starts the 15-minute

classification and fire extinguishment clocks. The 15-minute period to extinguish the fire

does not start until either the fire alarm is verified to be valid by utilization of additional

Control Room or nearby fire panel instrumentation, or upon notification of a fire from the

field.

Revision 21 of the EAL HU6 Basis allowed delay of the 15-minute classification time by

the dispatching of personnel, reporting the notification of a fire from the field, and

extinguishing the fire. As a result, this change indefinitely extended the start of the

15-minute emergency classification clock beyond a credible notification that a fire is

3 Enclosure 2

occurring or indication of a valid fire detection system alarm. This was determined to be

a decrease in effectiveness of the licensees emergency plan because the change

reduced the capability to perform a risk significant planning standard function in a timely

manner. This change was not submitted to the NRC for prior approval.

Analysis:

The inspector determined that the change made by the licensee to the EAL HU6 Basis

decreased the effectiveness of the Emergency Plan and the change was implemented

without prior NRC approval. The issue was determined to be a licensee performance

deficiency that impacted the regulatory process and, in accordance with Manual Chapter

(MC) 0612 Power Reactor Inspection Reports, was evaluated using the NRCs

traditional enforcement policy as well as the Reactor Oversight Process (ROP).

Using the NRCs Enforcement Policy, this violation met Example c.2 in Section 6.6: A

licensees ability to meet or implement any regulatory requirement related to assessment

or notification is degraded such that the effectiveness of the emergency plan decreases.

Although the regulatory requirement could be implemented during the response to an

actual emergency, the implementation would be degraded (e.g., not fully effective,

inappropriately delayed). Specifically, the change made to the EAL Basis directly

affected the Risk Significant Planning Standard Classification, which affected

assessment of event conditions. Therefore, this violation met the example for Severity

Level III. However, the NRC has classified this violation as a Severity Level IV, after

determining that its actual and potential safety significance was very low based on the

following considerations: (1) the issue involved only one Unusual Event EAL, and not

any of the other higher event classifications; and (2) the issue could delay classification

but would not prevent classification.

Using MC 0612 Power Reactor Inspection Reports, Appendix B, Issue Screening, the

performance deficiency was determined to be more than minor and, therefore, a finding,

because it is associated with the emergency preparedness cornerstone attribute of

procedure quality for EAL and emergency plan changes, and it adversely affected the

cornerstone objective of ensuring that the licensee is capable of implementing adequate

measures to protect the health and safety of the public in the event of a radiological

emergency. Specifically, the licensee made a change to its EAL Basis, which was a

decrease in effectiveness, because the change indefinitely extended the start of the

15-minute emergency classification clock beyond a credible notification that a fire is

occurring or indication of a valid fire detection system alarm. Also, this change was

made without prior NRC approval.

The inspector determined the finding could be evaluated using the Significance

Determination Process (SDP) in accordance with Inspection Manual Chapter (IMC) 0609, Significance Determination Process, Appendix B, Emergency Preparedness

Significance Determination Process. The finding is a failure to comply with

10 CFR 50.54(q) involving the risk significant planning standard 50.47(b)(4), which, in

this case, is not considered degraded. This EAL Classification finding is Green because

it involved one Unusual Event classifications (EAL HU6).

This finding has a cross-cutting aspect in the area of human performance,

decision-making, because the licensee failed to use conservative assumptions when

making decisions and did not demonstrate that nuclear safety was an overriding priority.

4 Enclosure 2

Specifically, the licensee changed its EAL Basis to indefinitely extend the start of the

15-minute emergency classification clock beyond a credible notification that a fire is

occurring or indication of a valid fire detection system alarm for one EAL HU6. This

change was screened through the licensees 50.54(q) process and was not identified as

a decrease in effectiveness. However, after evaluation by the inspector, this change

was determined to be a decrease in effectiveness of the emergency plan which was not

approved by the NRC before the change was implemented.

Enforcement:

Title 10 of the CFR 50.54(q) states, in part, AA licensee authorized to possess and

operate a nuclear power reactor shall follow and maintain in effect emergency plans

which meet the standards in '50.47(b) and the requirements in Appendix E of this part.

The nuclear power reactor licensee may make changes to these plans without

Commission approval only if the changes do not decrease the effectiveness of the plans

and the plans, as changed, continue to meet the standards of '50.47(b) and the

requirements of Appendix E to this part.

Title 10 CFR 50.47(b)(4) states, in part, A standard emergency classification and action

level scheme, the bases of which include facility system and effluent parameters, is in

use by the nuclear facility licensee, and State and local response plans call for reliance

on information provided by facility licensees for determinations of minimum initial offsite

response measures.@

Contrary to the above, as of March 28, 2008, the licensee made a change to the

emergency classification process which decreased the effectiveness of their emergency

plan and caused the emergency plan to no longer meet the standards of 50.47(b) and

Appendix E to this part without Commission approval. Specifically, the licensee modified

the EAL Basis in EAL HU6, Revision 21, to delay the 15-minute classification time by the

dispatching of personnel, reporting the notification of a fire from the field, and

extinguishing the fire. As a result, this change indefinitely extended the start of the

15-minute emergency classification clock beyond a credible notification that a fire is

occurring or indication of a valid fire detection system alarm. This change decreased the

effectiveness of the emergency plan by reducing the capability to perform a risk

significant planning function in a timely manner.

This violation impacted the regulatory process, was of very low safety significance and

was also entered into the licensees corrective action program as IR 01008718 dated

December 22, 2009. The violation is being cited in the Notice and a response is

required because no corrective action had been taken to restore compliance since the

issue was entered in your corrective action program in December 2009. This violation is

determined to be a Severity Level IV Cited Violation, consistent with Section 2.3.3 of the

NRC Enforcement Policy (NOV 05000456/2010503-01; NOV 05000457/2010503-01).

This issue has also been dispositioned as a Finding of very low safety significance

(Green) (FIN 05000456/2010503-01, FIN 05000457/2010503-01).
