Report Details1 Summary of Plant Activities During the period covered by this inspection, the plant remained in SAFESTOR with no major decommissioning work activities in progress.
1.0 Facility Management and Control 1.1 General The inspectors conducted reviews of ongoing activities in order to assess overall management and controls. Specific events and findings are detailed in the following sections.
1.2 Plant Tours to Evaluate Material Conditions and Housekeeping a. Inspection Scope (IP 71801)
The inspectors participated in three plant tours of the Fuel Handling Building, including the spent fuel pool storage area, with the Operations/Engineering Manager to evaluate the material integrity of structures, systems, and components necessary for the safe storage of spent fuel.
b. Observations and Findings The spent fuel pool area and support systems were clear and free of obstacles and debris. No fire hazards were observed. No degradation of structures, systems, and components important to the defueled condition were observed. Monitoring systems required to maintain the Spent Fuel Nuclear Island (SFNI ) were in good working order.
Overhead lights in the spent fuel pool area were recently replaced and the lighting was good. Lights were staggered (some on/some off) so that as lights burnt out, there would be other lights available to turn on. The control room was manned and met Technical Specification requirements.
c. Conclusions The material integrity of structures, systems, and components necessary for the safe storage of spent fuel and for the conduct of safe decommissioning was being maintained. Plant housekeeping was good. Control room manning met regulatory requirements.
Note: A list of acronyms used in these Details is provided at the end of the report.
2.0 Decommissioning Support Activities 2.1 Cold Weather Preparations (71714)
a. Inspection Scope The inspectors reviewed implementation of the licensees winterization procedure, PT 35W, Winter Operation Verification.
b. Observations and Findings There were no deficiencies in the licensees implementation of the winterization procedure, PT 35W. The inspectors did not identify any adverse conditions that could affect the operation of the SFNI cooling system. Frequency of equipment monitoring and surveillance testing were adequate to maintain proper operation of SFNI cooling systems and other plant functions. The winterization procedure specifically addressed all areas critical to adequately maintaining SFNI cooling systems and monitoring functions in an operating condition. The licensees practice of maintaining lighting and heat in selected plant areas on an as-needed basis was a function of limited resources.
No problems were identified by the inspectors.
c. Conclusions The licensee adequately maintained operational safety, the station winterization checklist was comprehensive, and the SFNI was adequately monitored.
2.2 Physical Security Plan (81018)
a. Inspection Scope The inspection included an in-office review of Revision 2 to the Zion Nuclear Power Station Defueled Physical Security Plan. Revision 2 was submitted by the licensee under 10 CFR 50.54(p)(2) requirements, and was submitted by licensee letter dated November 12, 2001.
b. Observation and Findings Revision 2 was submitted to clarify licensee commitments regarding search activities of hand-carried items, to define bullet-resistant in accordance with NRC requirements, and to define the frequency for testing and inspecting certain security equipment.
These plan modifications did not constitute changes that decreased specific plan commitments or security equipment performance.
c. Conclusions The licensees security plan changes identified in Revision 2 were in accordance with 10 CFR 50.54(p)(2) regulatory requirements.
