SUMMARY

OF NRC BULLETIN 2011-01 "MITIGATING STRATEGIES" RESPONSE REVIEW PSEG NUCLEAR LLC HOPE CREEK NUCLEAR GENERATING STATION, UNIT 1 DOCKET NO. 50-354

1.0 INTRODUCTION

On May 11, 2011, the U.S. Nuclear Regulatory Commission (NRC) issued Bulletin (BL) 2011-01, "Mitigating Strategies," (Agencywide Documents Access and Management System (ADAMS) Accession No. ML111250360) to all holders of operating licenses for nuclear power reactors, except those that have permanently ceased operation and have certified that fuel has been removed from the reactor vessel.

BL 2011-01 required two sets of responses pursuant to the provisions of with Title 10 of the Code of Federal Regulations (10 CFR) Section 50.54(f). The first set of responses were due 30 days after issuance of BL 2011-01.

By letter dated June 9, 2011 (ADAMS Accession No. ML111600253), Hope Creek Nuclear Generating Station (Hope Creek) provided its response to this first set of questions (first response). The second responses were due 60 days after issuance of the bulletin. By letter dated July 11, 2011 (ADAMS Accession No. ML111930027), Hope Creek provided its response to this second set of questions (second response). By letter dated November 14, 2011 (ADAMS Accession No. ML113110248), the NRC sent a request for additional information (RAI) on the second response. Hope Creek responded to the RAI by letter dated December 12, 2011 (ADAMS Accession No. ML113470207). As summarized below, the NRC staff has verified that Hope Creek provided the information requested in the bulletin.

2.0 BACKGROUND

On February 25, 2002, the NRC issued EA-02-026, "Order for Interim Safeguards and Security Compensatory Measures" (ICM Order). Section B.5.b of the ICM Order required licensees to develop specific guidance and strategies to maintain or restore core cooling, containment, and spent fuel pool cooling capabilities using readily available resources (equipment and personnel),

that can be effectively implemented under the circumstances associated with the loss of large areas of the plant due to explosions or fire.

By letter dated August 9, 2007 (ADAMS Accession No. ML072180018), the NRC staff issued its Safety Evaluation (SE) to document the final disposition of information submitted by Hope Creek regarding Section B.5.b of the ICM Order. Along with the SE, the NRC staff issued a conforming license condition to incorporate the B.5.b mitigating strategies into the licensing basis.

Enclosure

-2 On March 27, 2009, the NRC issued 10 CFR SO.S4(hh)(2) as a new rule, in order to capture the B.S.b mitigating strategies and related license conditions as regulatory requirements for both current and future licensees. At that time, licensee compliance with the conforming license conditions was sufficient to demonstrate compliance with 10 CFR SO.S4(hh)(2) (74 FR 13926);

therefore, no further actions were required on the part of current licensees.

3.0 TECHNICAL EVALUATION

3.1 30-Day Request In order to confirm continued compliance with 10 CFR SO.S4(hh)(2), BL 2011-01 requested that licensees address the following two questions within 30 days of issuing the bulletin:

1. Is the equipment necessary to execute the mitigating strategies, as described in your submittals to the NRC, available and capable of performing its intended function?
2. Are the guidance and strategies implemented capable of being executed considering the current configuration of your facility and current staffing and skill levels of the staff?

The NRC staff reviewed Hope Creek's first response to determine if it had adequately addressed these questions, as summarized below.

3.1.1 Question 1: Availability and Capability of Equipment In its first response, Hope Creek confirmed that equipment it needs to execute the 10 CFR SO.S4(hh)(2) mitigating strategies is available and capable of performing its intended function. The NRC staff verified that this confirmation covered equipment needed for each of the three phases of the B.S.b mitigation strategies. Therefore, the NRC staff finds that Hope Creek has adequately responded to Question 1.

3.1.2 Question 2: Guidance and Strategies Can Be Executed In its first response, Hope Creek confirmed that the guidance and strategies it has implemented for 10 CFR SO.S4(hh)(2) are capable of being executed considering the current facility configuration, staffing levels, and staff's skills. Since Hope Creek has considered its current facility configuration, staffing levels, and staff's skills, and confirmed that it can execute its implemented guidance and strategies, the NRC staff finds that Hope Creek has adequately responded to Question 2.

3.2 60-Day Request BL 2011-01 required a response to the following five questions within 60 days of issuing the bulletin:

1. Describe in detail the maintenance of equipment procured to support the strategies and guidance required by 10 CFR SO.S4(hh)(2) in order to ensure that it is functional when needed.

-3

2. Describe in detail the testing of equipment procured to support the strategies and guidance required by 10 CFR 50.54(hh)(2) in order to ensure that it will function when needed.
3. Describe in detail the controls for ensuring that the equipment is available when needed.
4. Describe in detail how configuration and guidance management is ensured so that strategies remain feasible.
5. Describe in detail how you ensure availability of offsite support.

The NRC staff reviewed Hope Creek's submittals to determine if it had adequately addressed these questions, as summarized below. The NRC staff also reviewed the August 9,2007, SE to determine what equipment, training, and offsite resources at Hope Creek were relied upon by NRC staff to conclude that Hope Creek's actions would ensure compliance with Section B.5.b of the ICM Order and the conforming license condition.

3.2.1 Questions 1 and 2: Maintenance and Testing of Equipment Questions 1 and 2 of the 60-day request required licensees to describe in detail the maintenance and testing of equipment procured to support the strategies and guidance required by 10 CFR 50.54(hh)(2), in order to ensure that it is functional when needed. In its second response, Hope Creek listed the equipment used to support the 10 CFR 50.54(hh)(2) mitigating strategies which receives maintenance or testing. For each item, Hope Creek described the maintenance and testing performed, including the frequency and basis for the maintenance or testing activity.

The NRC staff verified that Hope Creek listed equipment that typically requires maintenance or testing which was relied upon to make conclusions in the SE or commonly needed to implement the mitigating strategies. In its second response, Hope Creek stated that the fire truck, portable pump, portable power supplies, hoses, and communications equipment receive maintenance or testing. Hope Creek did not identify maintenance or testing of monitor nozzles, spray nozzles, or similar devices in its second response. In its RAI response, Hope Creek stated that its refuel floor monitor nozzle, portable spray nozzles, and fire truck mounted spray nozzle do not receive periodic maintenance or testing, but are included in the inventory. The monitor nozzle was tested prior to installation. In its RAI response, Hope Creek described how it ensures there is sufficient fuel for the portable pump. Hope Creek also identified other items that support the mitigating strategies that receive maintenance or testing.

The NRC staff verified that Hope Creek described the process used for corrective actions and listed the testing performed to ensure that the strategies were initially feasible. Hope Creek stated in its second response that its corrective action program is used to document equipment failure, establish priorities, and perform trending.

Based upon the information above, the NRC staff finds that Hope Creek has provided the information requested by Questions 1 and 2.

-4 3.2.2 Question 3: Controls on Equipment Question 3 of the 50-day request required licensees to describe in detail the controls on equipment, such as inventory requirements, to ensure that the equipment is available when needed. A list of inventory deficiencies and associated corrective actions to prevent loss was also requested.

The NRC staff verified that Hope Creek described its process for ensuring that B.S.b equipment will be available when needed. In its second response, Hope Creek identified equipment included in its inventory, the inventory frequency, and storage requirements. Hope Creek indicated that its inventory verifies that the equipment listed is available. Hope Creek stated that at the time of its second response, there were no outstanding inventory deficiencies that would render the strategies not viable.

The NRC staff verified that Hope Creek inventoried equipment which was relied upon to make conclusions in the SE or commonly needed to implement the mitigating strategies. In its second response, Hope Creek stated that procured non-permanently installed B.S.b equipment is inventoried at least annually in accordance with station procedures. The second response specifically stated that the following items are included in the inventory: portable pump; fire truck; portable power supplies; hoses; communications equipment; nozzles; and adapters.

Hope Creek also identified other items that support the mitigating strategies that are inventoried.

Based upon the information above, the NRC staff finds that Hope Creek has provided the information requested by Question 3.

3.2.3 Question 4: Configuration and Guidance Management Question 4 of the 50-day request required licensees to describe in detail how configuration and guidance management is assured so that the strategies remain feasible.

The NRC staff verified that Hope Creek described its measures to evaluate plant configuration changes for their effects on the mitigating strategies and to ensure its procedures are current.

In its second response, Hope Creek stated that plant configuration changes are procedurally evaluated against the licensing basis, which includes the B.S.b mitigating strategies. Hope Creek stated that the design change process requires a review of affected procedures and guidelines and that guideline changes are validated to ensure that the B.S.b mitigating strategies remain viable.

The NRC staff verified that Hope Creek described measures it has taken to validate the procedures or guidelines developed to support the mitigating strategies. In its second response, Hope Creek identified testing in response to Question 2 that demonstrated the ability to execute some strategies. Hope Creek also stated that, "Initially, mitigating strategies were validated by walkdowns, engineering evaluations and/or table top reviews," and they were similarly revalidated in 2011.

The NRC staff verified that Hope Creek described the training program implemented in support of the mitigating strategies and how its effectiveness is evaluated. In its second response, Hope Creek identified the training provided to its operations personnel, emergency response

-5 organization, and fire brigade. Hope Creek also identified the frequency with which each type of training is provided and the methods for evaluating the training.

Based upon the information above, the NRC staff finds that Hope Creek has provided the information requested by Question 4.

3.2.4 Question 5: Offsite Support Question 5 of the SO-day request required licensees to describe in detail how offsite support availability is assured.

The NRC staff verified that Hope Creek listed the offsite organizations it relies upon for emergency response, including a description of agreements and related training. The NRC staff compared the list of offsite organizations that Hope Creek provided in its second response with the information relied upon to make conclusions in the SE. Hope Creek stated that it maintains a memorandum of understanding with these offsite organizations, which are reviewed at least biennially, and that these agreements were current at the time of its second response. Hope Creek also described the training and site familiarization it provides to these offsite organizations. Hope Creek stated that it reviewed its corrective action program back to 2008 and found no issues involving lapsed agreements related to offsite support for B.5.b events.

Based upon the information above, the NRC staff finds that Hope Creek has provided the information requested by Question 5.
