Cornerstone: Emergency Preparedness
1EP6 Drill Evaluation
a. Inspection Scope
Resident inspectors evaluated the conduct of a routine licensee emergency drill on March 16, 2005, to identify any weaknesses and deficiencies in classification, notification, and protective action recommendations (PARs) development activities. The inspectors observed emergency response operations in the simulated control room and the technical support center to verify that event classification and notifications were done in accordance with EPIP-1, Emergency Plan Classification Matrix, Revision 36.
The inspectors also attended the licensee critique of the drill to compare any inspector-observed weakness with those identified by the licensee in order to verify whether the licensee was properly identifying failures.
b. Findings
No findings of significance were identified.
OTHER ACTIVITIES
4OA2 Identification and Resolution of Problems
Daily Review As required by Inspection Procedure 71152, Identification and Resolution of Problems, and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensees corrective action program. This was accomplished by reviewing the description of each new PER and attending management review committee meetings.
4OA3 Event Followup
Unit 2 Manual Reactor Trip With Loss of Normal Heat Sink On February 23, 2005, following a Unit 2 reactor trip due to inadvertent operation of two DC control power breakers by maintenance personnel, the inspectors evaluated plant status, mitigating actions, and the licensees classification of the event, to enable the NRC to determine an appropriate NRC response. Opening of the breakers removed control power to all four feedwater regulating valves causing them all to close simultaneously, which resulted in a loss of the normal heat sink.
The event was reported to the NRC as event notification41437 and documented in the licensee corrective action program as PER 77234. The inspectors review of the cause of the event was ongoing at the end of this report period. Disposition of the performance deficiencies that precipitated this event will be done in the subsequent integrated inspection report in conjunction with closure of the licensees pending Licensee Event Report (LER).
4OA5 Other Activities
Institute of Nuclear Power Operations (INPO) Plant Assessment Report Review
a. Inspection Scope
The inspectors reviewed the final report for the INPO plant assessment of Sequoyah conducted in August 2004. The inspectors reviewed the report to ensure that issues identified were consistent with the NRC perspectives of licensee performance and to verify if any significant safety issues were identified that required further NRC follow-up.
b. Findings
No findings of significance were identified.
4OA6 Meetings, including Exit
.1 Exit Meeting Summary
On April 1, 2005, the resident inspectors presented the inspection results to Mr. R.
Douet and other members of his staff, who acknowledged the findings.
