Cornerstone: Emergency Preparedness

1 EP 1 Exercise Evaluation (71114.01

- 1 sample)

a. Inspection Scope

On November 14, 2017, Exelon conducted a biennial emergency preparedness exercise at the Limerick Generating Station. The NRC inspectors evaluated the adequacy of Exelon's conduct of the exercise and its capability to assess staff performance via a formal critique process, as required by Title 10 of the Code of Federal Regulations (10 CFR) 50.47(b)(14). This overall exercise inspection activity represented the completion of one sample on a biennial cycle.

T o evaluate the exercise, t he inspectors reviewed

The adequacy of Exelon's performance in the biennial full

-participation exercise regarding the implementation of the planning standards described in 10 CFR 50.47(b)(4), (5), (9), and (10), which are: emergency classification, offsite notification, radiological assessment, and onsite and public protective action recommendations, respectively.

The overall adequacy of Exelon's emergency response facilities with regard to Limerick emergency plan commitments. The inspectors assessed the following facilities: the simulator control r oom, the technical support center, the operations support center, and the emergency operations facility.

Exelon's performance in other areas, such as: the emergency response organization's (ERO) recognition of abnormal plant conditions, command and control, communications both within and between facilities, prioritization of mitigation activities, utilization of repair and field monitoring teams, interface with offsite agencies, staffing and procedure adequacy, and the overall implementation of the Limerick emergency plan and its implementing procedures.

A review of past performance issues from the last biennial exercise inspection report and Exelon's emergency preparedness drill reports, to determine the effectiveness of corrective actions as demonstrated during the November 14, 2017, exercise and to ensure compliance with 10 CFR 50.47(b)(14), which requires licensees to conduct periodic drills and exercises and to correct any deficiencies identified

.

The post-exercise critiques, to evaluate Exelon's self

-assessment of its ERO performance during the November 14, 2017, exercise and to ensure compliance with 10 CFR Part 50, Appendix E, Section IV.F.2.g.

Documents reviewed for each section of this inspection report are listed in the Attachment.

This overall exercise inspection activity represented the completion of one sample on a biennial cycle.
