Cornerstone: Emergency Preparedness (EP)

1EP1 Exercise Evaluation (71114.01 - 1 Sample)

a. Inspection Scope

Prior to the November 15, 2011, emergency preparedness exercise, the NRC inspectors conducted an in-office review of the exercise objectives and scenario, which Exelon had submitted to the NRC, to determine if the exercise would test major elements of the Limerick Emergency Plan as required by Title 10 of the Code of Federal Regulations (10 CFR) 50.47(bX14). This overall exercise inspection activity represented the completion of one sample on a biennial cycle.

The exercise evaluation consisted of the following review and assessment:

.

The adequacy of Exelon's performance in the biennial full-participation exercise regarding the implementation of the risk-significant planning standards (RSPS)described in 10 CFR 50.47(bX4), (5), (9), and (10), which are: emergency classification; offsite notification; radiological assessment; and protective action recommendations, respectively.

o The overall adequacy of Exelon's Limerick emergency response facilities with regard to NUREG-0696, "Functional Criteria for Emergency Response Facilities,"

and Emergency Plan commitments. The facilities assessed were the Control Room Simulator, Operations Support Center (OSC),Technical Support Center (TSC),

Emergency Operations Facility (EOF), and the Joint Information Center (JlC).

o A review of other performance areas, such as: the Limerick emergency response organization's (ERO) recognition of abnormal plant conditions; command and control; intra-and inter-facility communications; prioritization of mitigating activities; utilization of repair and field monitoring teams; interface with offsite agencies; staffing and procedure adequacy; and the overall implementation of the emergency plan and its implementing procedures.

r A review of past performance issues from the last NRC Limerick EP exercise inspection report and Exelon's Limerick EP drill reports, to determine the effectiveness of licensee corrective actions as demonstrated during the November 15, 2011, exercise and to ensure compliance with 10 CFR 50.47(b)(14).

o The licensee's post-exercise critiques, to evaluate Exelon's self-assessment of its ERO performance during the November 15, 2011, Limerick exercise and to ensure compliance with 10 CFR Part 50, Appendix E, Section lV.F.2.g.

1EP4 Emerqencv Action Level and Emeroencv Plan Changes (71114.04 - 1 Sample)a.

lnspection Scope Since the last NRC inspection of this program area, in December 2010, Exelon implemented various revisions of the different sections of the Limerick Emergency Plan.

Exelon had determined that, in accordance with 10 CFR 50.54(q), any change made to the Plan, and its lower-tier implementing procedures, had not resulted in any decrease in effectiveness of the Plan, and that the revised Plan continued to meet the requirements of 10 CFR 50.47(b) and Appendix E to 10 CFR Part 50. The inspectors reviewed all emergency action level (EAL) changes that Exelon had made since December 2010, and conducted a sampling review of other Emergency Plan changes, including the changes to lowertier erfiergency plan implementing procedures, to evaluate for any potential decreases in effectiveness of the Emergency Plan. However, this review was not documented in an NRC Safety Evaluation Report and does not constitute formal NRC approval of the changes. Therefore, these changes remain subject to future NRC inspection in their entirety.

(3) Alert and Notification System (ANS) Reliability. The last NRC EP inspection at Limerick was conducted in the fourth quarter of 2010, so the inspectors reviewed supporting documentation from EP drills, training records, and equipment tests from the fourth calendar quarter of 2010 through the third quarter of 2011, to verify the accuracy of the reported performance indicator (Pl) data. The review of these Pls was conducted in accordance with NRC Inspection Procedure 71151, using the acceptance criteria documented in NEI 99-02, "Regulatory Assessment Performance Indicator Guidelines," Revision 6.
