The objective of Temporary Instruction (TI) 2015/191 "Inspection of the Implementation of Mitigation Strategies and Spent Fuel Pool Instrumentation Orders and Emergency Preparedness Communication/Staffing/Multi
-Unit Dose Assessment Plans" is to verify that licensees have adequately implemented the mitigation strategies as described in the licensee's Final Integrated Plan (ADAMS Accession No.
ML15364A034) and the NRC's plant safety evaluation (ADAMS Accession No. ML16088A261) and to verify that the licensee installed reliable water
-level measurement instrumentation in their spent fuel pools. The purpose of this TI is also to verify the licensees have implemented Emergency Preparedness (EP) enhancements as described in their site
-specific submittals and NRC safety assessments, including multi
-unit dose assessment capability and enhancements to ensure that staffing is sufficient and communications can be maintained during such an event.
The inspection verifies that plans for complying with NRC Orders EA 049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond
-Design-Basis External Events (ADAMS Accession No. ML12229A174) and EA 051, Order Modifying Licenses With Regard to Reliable Spent Fuel Pool Instrumentation (ADAMS Accession No. ML12056A044) are in place and are being implemented by the licensee. Additionally, the inspection verifies implementation of staffing and communications information provided in response to the March 12, 2012 request for information letter and multiunit dose assessment information provided per COMSECY-13-0010, Schedule and Plans for Tier 2 Order on Emergency Preparedness for Japan Lessons Learned, dated March 27, 2013 (ADAMS Accession No. ML12339A262).
The team discussed the plans and strategies with plant staff, reviewed documentation, and where appropriate, performed plant walk downs to verify that the strategies could be implemented as stated in the licensee's submittals and the NRC staff prepared safety evaluation. For most strategies, this included verification that the strategy was feasible, procedures and/or guidance had been developed, training had been provided to plant staff, and required equipment had been identified and staged. Specific details of the team's inspection activities are described in the following sections.
1. Mitigation Strategies for Beyond
-Design-Basis External Events
a. Inspection Scope
The team examined the licensee's established guidelines and implementing procedures for the beyond
-design-basis mitigation strategies. The team assessed how the licensee coordinated and documented the interface/transition between existing off
-normal and Emergency Operating Procedures with the newly developed mitigation strategies. The team selected a number of mitigation strategies and conducted plant walk downs with licensed operators and responsible plant staff to assess: the adequacy and completeness of the procedures; familiarity of operators with the procedure objectives and specific guidance; staging and compatibility of equipment; and the practicality of the operator actions prescribed by the procedures, consistent with the postulated scenarios.
The team verified that a preventive maintenance program had been established for the FLEX portable equipment and that periodic equipment inventories were in place and being conducted. Additionally, the team examined the introductory and planned periodic/refresher training provided to the Operations and Fire Protection staffs most likely to be tasked with implementation of the FLEX mitigation strategies.
The team also reviewed the introductory and planned periodic training provided to the Emergency Response Organization personnel. Documents reviewed are listed in the attachment.
b. Assessment Based on samples selected for review, the inspectors verified that the licensee satisfactorily implemented appropriate elements of the FLEX strategy as described in the plant specific submittals and the associated safety evaluation and determined that the licensee is generally in compliance with NRC Order EA 049. The inspectors verified that the licensee satisfactorily:
Developed and issued FLEX Support Guidelines (FSG) to implement the FLEX strategies for postulated external events
- Integrated their FSGs into their existing plant procedures such that entry into and departure from the FSGs are clear when using existing plant procedures
- Protected FLEX equipment from site
-specific hazards
- Developed and implemented adequate testing and maintenance of FLEX equipment to ensure their availability and capability
- Trained their staff to assure personnel proficiency in the mitigation of beyond-design-basis events; and Developed means to ensure that the necessary off
-site FLEX equipment will be available from off
-site locations
. The inspectors verified that non
-compliances with current licensing requirements, and other issues identified during the inspection were entered into the licensee's corrective action program.
c. Findings
No findings identified.
. Spent Fuel Pool (SFP) Instrumentation
a. Inspection Scope
The team examined the licensee's newly installed spent fuel pool instrumentation. Specifically, the inspectors verified the sensors were installed as described in the plant specific submittals and the associated safety evaluation and that the cabling for the power supplies and the indications for each channel are physically and electrically separated. Additionally, environmental conditions and accessibility of the instruments were evaluated. Documents reviewed are listed in the attachment.
b. Assessment Based on samples selected for review, the inspectors determined that the licensee satisfactorily installed and established control of the SFP instrumentation as described in the plant specific submittals and the associated safety evaluation and determined that the licensee is generally in compliance with NRC Order EA 051. The inspectors verified that the licensee satisfactorily:
Installed the SFP instrumentation sensors, cabling and power supplies to provide physical and electrical separation as described in the plant specific submittal and safety evaluation
- Installed the SFP instrumentation display in the location, environmental conditions and accessibility as described in the plant specific submittals; and Trained their staff to assure personnel proficiency with the maintenance, testing, and use of the SFP instrumentation.
The inspectors verified that non
-compliances with current licensing requirements, and other issues identified during the inspection were entered into the licensee's corrective action program.
c. Findings
No findings identified.
3. Staffing and Communication Request for Information
a. Inspection Scope
Through discussions with plant staff, review of documentation and plant walk downs, the team verified that the licensee has implemented required changes to staffing, communications equipment and facilities to support an Extended Loss of All AC Power (ELAP) scenario as described in the licensee's staffing assessment and the NRC safety assessment. The team also verified that the licensee has implemented dose assessment (including releases from spent fuel pools) capability using the licensee's site-specific dose assessment software and approach as described in the licensee's dose assessment submittal. Documents reviewed are listed in the attachment.
b. Assessment The inspectors reviewed information provided in the licensee's multi
-unit dose submittal and in response to the NRC's March 12, 2012, request for information letter and verified that the licensee satisfactorily implemented enhancements pertaining to Near
-Term Task Force Recommendation 9.3 response to a large scale natural emergency event that results in an extended loss of all ac power to the site and impedes access to the site.
The inspectors verified the following:
Licensee satisfactorily implemented required staffing change(s) to support an ELAP scenario; Emergency preparedness communications equipment and facilities are sufficient for dealing with an ELAP scenario; and Implemented dose assessment capabilities (including releases from spent fuel pools) using the licensee's site
-specific dose assessment software and approach.
The inspectors verified that non
-compliances with current licensing requirements, and other issues identified during the inspection were entered into the licensee's corrective
action program.
c. Findings
No findings identified.
