ENCLOSURE 1 LR-N14-0187 Salem Generating Station Units 1 and 2 Third Six-Month Status Report for the Implementation of Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events Salem Generating Station Units 1 and 2 PSEG Nuclear LLC

ENCLOSURE 1 LR-N14-0187 1 Introduction PSEG Nuclear LLC (PSEG) developed an Overall Integrated Plan (OIP) (Reference 1) for the Salem Generating Station (SGS) Units 1 and 2, documenting the diverse and flexible coping strategies (FLEX) in response to NRC Order EA-12-049 (Reference 2).

References 3 and 4 transmitted the first and second SGS FLEX six-month status reports, respectively. This report is the third six-month status report, which provides implementation status as of July 31, 2014. This update follows the guidance in Section 13.2 of Nuclear Energy Institute (NEI) Report 12-06 (Reference 5), which states that the six-month status reports should include an update of milestone accomplishments since the previous report, changes to the compliance method, schedule, and the need for relief and the basis for relief, if applicable. Sections 2 and 3 of this status report include milestone accomplishments and milestone schedule status, respectively. Section 4 identifies changes to the method of compliance with NEI 12-06.

Section 5 describes the request for schedule relaxation (Reference 6) for Salem Unit 1 associated with reactor coolant pump seal leakage.

2 Milestone Accomplishments The following milestones have been completed since the development of the SGS FLEX OIP, and are current as of July 31, 2014.

• Submit Integrated Plan: PSEG submitted the SGS FLEX OIP to the NRC.

• Develop FLEX Strategies: PSEG has developed SGS Units 1 and 2 FLEX strategies as described in the SGS FLEX OIP and has identified design, analysis, procurement, and programmatic actions necessary to achieve compliance with Order EA-12-049. Changes to the FLEX strategies involving changes to methods of compliance with NEI 12-06 are described in Section 4.

• Perform Staffing Analysis - PSEG completed an analysis of the staff needed to implement the SGS FLEX strategies during a beyond-design-basis external event, and transmitted the staffing assessment report to the NRC via Reference 7.

• Develop Training Plan - PSEG developed training materials and schedules, and has begun training personnel on the SGS mitigation strategies.

3 Milestone Schedule Status The following table provides an update of SGS FLEX OIP milestones. The table provides the milestone activity status and indicates whether the original expected completion date has changed. The dates are planning dates subject to change as design and implementation details are developed. The revised milestone target completion dates reflect the pending NRC Order EA-12-049 compliance schedule relaxation request for Salem Unit 1 (Reference 6).

ENCLOSURE 1 LR-N14-0187 Section 3 Table Notes (continued)

4) The original EP communications improvement milestone is the target completion date associated with the milestone to complete installation, procedure revision, and training for satellite phone base units and antennae (Reference 9). The revised milestone is based on PSEG's regulatory commitment in Reference 10, to complete communications improvements prior to restart from the Salem Unit 1, 23rd Refueling Outage (S1R23) in Fall 2014.

5) The Salem Unit 1 milestone for affirming full compliance with NRC Order EA-12-049 is consistent with the pending schedule relaxation request to address reactor coolant pump seal leakage (Reference 6).

4 Changes to Compliance Method PSEG has made changes to the method of compliance with NEI 12-06 subsequent to the February 2014 status report (Reference 4). These changes continue to meet the requirements of NRC Order EA-12-049, as summarized below.

The SGS Phase 1 strategy is based on an alternative to initial conditions 1 and 3 of NEI 12-06 Section 3.2.1. 3. Initial condition 1 states that no specific initiating event is used, and initial condition 3 states "Cooling and makeup water inventories contained in systems or structures with designs that are robust with respect to seismic events, floods, and high winds, and associated missiles are available." The SGS FLEX strategy includes event-dependent consideration of cooling water availability, e.g., the Seismic Class I auxiliary feedwater storage tank (AFST) is assumed to remain available following a seismic event, but may become unavailable due to tornado missile damage.

Based on the capability to align diverse water supplies depending on the specific hazard, the SGS FLEX strategy is consistent with the overarching goal of reasonable protection of equipment such that no single event results in failure of the strategy.

SGS is using an alternative to the criteria of NEI 12-06 Section 7.3.1, "Protection of FLEX Equipment," which recommends protection of FLEX equipment from high wind hazards via storage in a structure or in diverse locations. Two FLEX DGs, electrical connections and distribution equipment will be stored in the canyon area (i.e., the area between the Salem Unit 2 fuel handling building and auxiliary building). This equipment and their associated connections will be stored outdoors and provided with protection from external hazards to minimize the probability that a single event would damage all of the FLEX equipment needed to mitigate the event.

SGS is using an alternative to the criteria of NEI 12-06 Section 8.3.1, "Protection of FLEX Equipment," which recommends storage of the N FLEX equipment within a structure to provide protection against snow, ice and extreme cold hazards. Outdoor storage locations are within the protected area and consist of the following:

• canyon area

• west of SGS

• east of the Salem Unit 1 condensate polisher building

• near the Hope Creek Unit 2 reactor building west wall, north of SGS 4 of 6

ENCLOSURE 1 LR-N14-0187 FLEX equipment stored outdoors will be protected as required by the manufacturer, e.g., equipped with direct heating features (e.g., engine block heater, etc.) to ensure it will function when called upon.

5 Need for Relief/Relaxation and Basis for the Relief/Relaxation The current schedule requirement for SGS Unit 1 implementation of NRC Order EA-12-049 is prior to restart from the 23rd refueling outage (S1R23) in Fall 2014.

PSEG requested schedule relaxation via Reference 6, to defer full implementation of NRC Order EA-12-049 by one refueling outage, i.e., prior to restart from S1R24 in Spring 2016. The requested relaxation would enable PSEG to address recently recalculated RCP seal leakage rates that exceed the Westinghouse generic values assumed in the SGS FLEX 01 P, by developing and implementing plant changes to reduce RCP seal leakage rates to values that are compatible with the assumptions of the SGS mitigation strategies. PSEG is proceeding with completion of other design, equipment procurement and programmatic changes to support the ability to implement the SGS Unit 1 mitigation strategies.

6 Open Items from Overall Integrated Plan and Draft Safety Evaluation Resolution of items identified in the NRC's interim staff evaluation for SGS (Reference 11) is being addressed as part of the mitigation strategies audit process.

7 Potential Draft Safety Evaluation Impacts Impacts to the NRC Safety Evaluation of SGS compliance with Order EA-12-049 are being addressed as part of the mitigation strategies audit process.
