SUMMARY

Inspection Report (IR) 05000440/2016009, 08/08/2016 - 08/12/2016, Perry Nuclear Power

Plant; Temporary Instruction 2515/191 Implementation of Mitigation Strategies and Spent Fuel Pool Instrumentation Orders and Emergency Preparedness Communication/Staffing/Multi-Unit Dose Assessment Plans.

This inspection was performed by four NRC regional inspectors. Two findings were identified.

The significance of inspection findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using Inspection Manual Chapter (IMC) 0609,

"Significance Determination Process," dated April 29, 2015. Cross-cutting aspects are determined using IMC 0310, "Aspects Within the Cross-Cutting Areas," dated December 4, 2014. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," dated July 2016.

Cornerstone: Mitigating Systems

Green.

A finding of very low safety significance was identified by the inspectors for failing to establish a periodic replacement program for the high-temperature rated hoses used during a mitigating strategy for suppression pool cooling. Specifically, the licensee failed to create a periodic replacement program for high temperature FLEX hoses based on the vendor recommendation of a six year shelf-life or justify deviation from the recommendation. The licensee entered this issue into the corrective action program as CR-2016-09776 with an action to generate the appropriate repetitive task for periodic replacement of the high-temperature rated hose. No violation of NRC requirements were identified.

This performance deficiency was determined to be more than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and adversely affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage), and is therefore a finding. The inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609, Significance Determination Process, appendix M, Significance Determination Process using Qualitative Criteria, informed by draft appendix O,

Significance Determination Process for Mitigating Strategies and Spent Fuel Pool Instrumentation (Orders EA-12-049 and EA-12-051). The finding screened as very low safety significance, Green, because the inspectors answered no to all Appendix O questions. This finding had a cross-cutting aspect of Procedure Adherence in the area of Human Performance because the licensee failed to follow procedural guidance to replace hoses based on vendor recommendations. (H.8) (Section 4OA5.1)

Cornerstone: Emergency Preparedness

Green.

A finding of very low safety significance was identified by the inspectors for failing to establish period tasks to check the operation of recently installed FLEX related communications equipment in accordance with the Perry Nuclear Power Plant FLEX Final Integrated Plan Report. The licensee entered this issue into the corrective action program as CR-2016-09746 and 2016-09747 to develop the appropriate periodic maintenance tasks.

The finding was determined to be more than minor because it was associated with the Emergency Preparedness Cornerstone Attribute of Facilities and Equipment which includes Maintenance Surveillance and Testing of Facilities, Equipment and Communications Systems. Specifically, communications equipment, particularly batteries, degrade over time and without periodic checks to verify functionality, the equipment might not be available for response to a potential accident. The inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609,

Significance Determination Process, appendix M, Significance Determination Process using Qualitative Criteria, informed by draft appendix O, Significance Determination Process for Mitigating Strategies and Spent Fuel Pool Instrumentation (Orders EA-12-049 and EA-12-051). The finding screened as very low safety significance,

Green, because the inspectors answered no to all Appendix O questions. This finding has a cross-cutting aspect in the area of Human Performance, Work Management because a task to create the activities was initiated, but the completion date was postponed well past the date at which the licensee declared compliance with mitigating systems orders. (H.5) (Section 4OA5.3)

REPORT DETAILS

4OA5 Other Activities (TI 2515/191)

The objective of Temporary Instruction (TI) 2515/191, 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 the licensee has adequately implemented the mitigation strategies as described in the licensees Final Integrated Plan Revision 0 (ADAMS Accession No. ML13064A243),

Revision 1 (ADAMS ML14268A214), Revision 2 (ADAMS ML15232A594), and the NRCs safety evaluation (ADAMS ML16056A560) and to verify the licensee installed reliable water-level measurement instrumentation in their spent fuel pool. The purpose of this TI was also to verify the licensee had 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 staffing is sufficient and communications can be maintained during such an event.

The inspection also verifies plans for complying with NRC Orders EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events (ADAMS Accession No. ML12229A174) and EA-12-051, 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 verified 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 inspectors discussed the plans and strategies with plant staff, reviewed documentation, and where appropriate, performed plant walk downs to verify the strategies could be implemented as stated in the licensees 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 teams inspection activities are described in the following sections.

1. Mitigation Strategies for Beyond-Design Basis External Events

a. Inspection Scope

The inspectors examined the licensees established guidelines and implementing procedures for the beyond-design basis mitigation strategies. The inspectors 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 inspectors 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 inspectors verified a preventive maintenance program had been established for the Diverse and Flexible Coping Strategies (FLEX) portable equipment and periodic equipment inventories were in place and being conducted. Additionally, the inspectors examined the introductory and planned periodic/refresher training provided to the Operations staff most likely to be tasked with implementation of the FLEX mitigation strategies. The inspectors 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 the licensee satisfactorily implemented appropriate elements of the FLEX strategy as described in the plant specific submittal(s) and the associated safety evaluation and determined the licensee is generally in compliance with NRC Order EA-12-049. The inspectors verified 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 were 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 the means to ensure the necessary off-site FLEX equipment would be available from off-site locations.

The inspectors verified non-compliances with current licensing requirements, and other issues identified during the inspection were entered into the licensee's corrective action program as appropriate.

c. Findings

(1) Failure to Implement a Periodic Replacement Program for FLEX Hoses

Introduction:

A finding of very low safety significance (Green) was identified by the inspectors for failing to establish a periodic replacement program for the high-temperature rated hoses used during a mitigating strategy for suppression pool cooling. Specifically, the licensee failed to create a periodic replacement program for high temperature rated FLEX hoses based on the vendor recommendation of a six year shelf-life or justify deviation from the recommendation.

Description:

The licensee established Flex Support Guidelines (FSG) 30.3 and 30.4 to provide instruction for the use of the Alternate Decay Heat Removal (ADHR) Pump for Suppression Pool Cooling using Residual Heat Removal (RHR) A and B, respectively.

These strategies utilize three 5 Nukflex high-temperature rated hoses that run from the connections on the discharge of the ADHR pump to the RHR system tie-in. The off-normal procedure for Station Blackout, ONI-R10-2, detailed that Suppression Pool Cleanup (SPCU) is the preferred method of cooling, however, both ADHR and SPCU are credited as viable strategies during a FLEX event.

Section 7.5 of the licensees FLEX Final Integrated Plan Report stated the licensee will create maintenance and testing programs based on NEI 12-06 guidance. Section 11.5 of NEI 12-06, Rev 0, stated, preventative maintenance should be developed based on vendor recommendations, and that any deviations should be documented. In addition, licensee fleet procedure NORM-ER-3730, Rev 1, also provided guidance, stating, in part, replace hose based on manufacturers or industry standard shelf life limits for the applicable environment.

The inspectors questioned the licensee regarding the preventative maintenance of the hoses. The licensee determined there was not a periodic replacement program in place, per both NEI and licensee guidance, and the only testing done was periodic visual inspection of the hoses. The licensee also stated they were not originally aware the vendor had a recommended shelf-life. Due to the inspectors questioning, the licensee contacted the vendor and was told the recommended shelf-life was six years. The hoses were approximately two years into their limited shelf-life; however, there was no replacement frequency specified and the licensee could not guarantee the hoses would be replaced and the strategy would be capable of fulfilling its function.

The licensee generated condition report CR-2016-09776 with a recommended action to generate the appropriate repetitive task for periodic replacement of the Nukflex high temperature hose.

Analysis:

The inspectors determined the failure to establish a periodic replacement program based on vendor recommendations or justify deviations from the recommendations was contrary to the guidance in NEI 12-06, Rev 0, and the licensees Final Integrated Plan, and therefore a performance deficiency.

The performance deficiency is more than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and adversely affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, because the licensee was unaware of the vendor requirements and had no plans to periodically replace the hoses, the licensee did not ensure the reliability of the hoses; therefore, this performance deficiency is a finding.

Issues identified through TI-191 are evaluated through a cross-regional panel using IMC 0609, Appendix M, Significance Determination Process Using Qualitative Criteria, as informed by draft Appendix O, Post Fukushima Mitigation Strategies Significance Determination Process (Orders EA-12-049 and EA-12-051) (ML16055A351). The finding was determined to be of very low safety significance (Green) because the inspector answered no to the 5 questions in the draft Appendix O. Specifically, this condition was not associated with Spent Fuel Pool Level instrumentation required by order A-12-051 and did not result in a complete loss of function to maintain or restore core cooling, containment pressure control/heat removal and/or spent fuel pooling cooling capabilities.

This finding has a cross-cutting aspect in the area of human performance, procedure adherence, which states individuals follow processes, procedures, and work instructions. Specifically, the licensee did not follow NORM-ER-3730, which provides guidance to replace hoses based on vendor recommendations. (H.8)

Enforcement:

This finding does not involve enforcement action because no violation of regulatory requirements was identified. Because the finding does not involve a violation of regulatory requirements and has very low safety significance, it is identified as FIN 05000440/2016009-01; Failure to Implement a Periodic Replacement Program for FLEX Hoses.

2. Spent Fuel Pool Instrumentation

a. Inspection Scope

The inspectors examined the licensees 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 the licensee satisfactorily installed and established control of the spent fuel pool (SFP)instrumentation as described in the plant specific submittal(s) and the associated safety evaluation and determined the licensee is generally in compliance with NRC Order EA-12-051. The inspectors verified 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(s) and safety evaluation;

• installed the SFP instrumentation display in the location, environmental conditions and accessibility as described in the plant specific submittal(s); and

• trained their staff to assure personnel proficiency with the maintenance, testing, and use of the SFP instrumentation.

The inspectors verified 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 were identified.

3. Staffing and Communication Request for Information

a. Inspection Scope

Through discussions with plant staff, review of documentation and plant walk downs, the inspectors verified the licensee has implemented required changes to staffing, communications equipment and facilities to support a multi-unit extended loss of AC power (ELAP) scenario as described in the licensees staffing assessment and the NRC safety assessment. The inspectors also verified the licensee has implemented multi-unit dose assessment (including releases from spent fuel pools) capability using the licensees site-specific dose assessment software and approach as described in the licensees multi-unit dose assessment submittal. Documents reviewed are listed in the attachment.

b. Assessment The inspectors reviewed information provided in the licensees multi-unit dose submittal and in response to the NRCs 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 all site units and impedes access to the site. The inspectors verified the following:

• the licensee satisfactorily implemented required staffing change(s) to support a multi-unit ELAP scenario;

• EP communications equipment and facilities are sufficient for dealing with a multi-unit ELAP scenario; and

• the licensee implemented multi-unit dose assessment capabilities (including releases from spent fuel pools) using the licensees site-specific dose assessment software and approach.

The inspectors verified non-compliances with current licensing requirements, and other issues identified during the inspection were entered into the licensee's corrective action program.

c. Findings

(1) Failure to Establish a Periodic Maintenance Program for Communications Equipment Associated with FLEX

Introduction:

A finding of very low safety significance (Green) was identified by the inspectors for failing to establish period tasks to check the operation of recently installed FLEX related communications equipment in accordance with the Perry Nuclear Power Plant FLEX Final Integrated Plan Report.

Description:

The inspectors reviewed activities associated with communications equipment intended for use during a potential extended loss of offsite power. The licensee had installed an uninterruptable power supply (UPS) for onsite communications equipment, and control room satellite phones to facilitate offsite communications during a potential extended loss of offsite power. The inspectors requested a listing of periodic maintenance (PM) established for these new pieces of equipment and were informed that there were no PMs established for this equipment. The inspectors were concerned that without PMs, the degradation of the equipment could go unnoticed and the equipment could be non-functional if ever required for an event.

The Perry Nuclear Power Plant (PNPP) FLEX Final Integrated Plan Report Section 12.2 states actions have been completed to place PNPP in full compliance with the communication requirements of NEI 12-01.

NEI 12-01 Guideline for Assessing Beyond Design Basis Accident Response Staffing and Communications Capabilities Section 4.8 Quality and Maintenance-Related Requirements states:

Programmatic controls should be applied to all communications-related equipment to ensure availability and reliability, including the performance of periodic inventory checks and operability testing.

Contrary to this, the licensee failed to establish periodic testing of FLEX related communications equipment.

In response to inspector concerns, the licensee initiated condition reports 2016-09746, 2016 NRC FLEX Inspection; PM Development for FLEX Communications System and 2016-09747 2016 NRC FLEX Inspection; Periodic Testing of FLEX Satellite Phones to develop periodic maintenance tasks. Prior to the end of the inspection, the licensee developed periodic maintenance tasks for the UPS.

Analysis:

The inspectors determined that failing to establish periodic testing of FLEX related communications equipment was contrary to NEI 12-01 and was a performance deficiency.

The performance deficiency was determined to be more than minor because it was associated with the Emergency Preparedness Cornerstone Attribute of Facilities and Equipment which includes Maintenance Surveillance and Testing of Facilities, Equipment and Communications Systems and adversely affect the associated cornerstone objective of ensuring the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. Specifically, communications equipment, particularly batteries, degrade over time and without a period checks to verify functionality, the equipment might not be available for response to a potential accident.

Issues identified through TI-191 are evaluated through a cross-regional panel using IMC 0609, Appendix M, Significance Determination Process Using Qualitative Criteria, as informed by draft Appendix O, Significance Determination Process for Mitigating Strategies and Spent Fuel Pool Instrumentation (Orders EA-12-049 and EA-12-051),

(ML16055A351). The finding screened as very low safety significance, Green, because the inspectors answered no to all Draft Appendix O questions. Specifically, this condition was not associated with Spent Fuel Pool Level instrumentation required by order A-12-051 and did not result in a complete loss of function to maintain or restore core cooling, containment pressure control/heat removal and/or spent fuel pooling cooling capabilities.

This finding has a cross-cutting aspect in the area of Human Performance, Work Management because the licensee did not implement a process of planning, controlling, and executing work activities such that nuclear safety is the overriding priority.

Specifically, a task to create the activities was initiated, but the completion date was postponed well past the date at which the licensee declared compliance with mitigating systems orders. (H.5)

Enforcement:

This finding does not involve enforcement action because no violation of regulatory requirements was identified. Because the finding does not involve a violation of regulatory requirements and has very low safety significance, it is identified as FIN 05000440/2016009-02, Failure to Establish a Periodic Maintenance Program for Communications Equipment Associated with FLEX.
