The following items were evaluated in accordance with the provisions of the Code of Federal Regulations 10CFR50.59.

The Station Operations Review Committee has reviewed and concurs with these evaluations.

ITEM A. Design Change Packages lEC-3252 Pkg 1 lEC-3340 Pkg 1

SUMMARY

"Reracking Of spent Fuel Pool For Increased Storage Capacity" -This DCP will remove nine existing Exxon racks and replace then with nine maximum density Holtec racks. Relocate three Exxon racks in the spent fuel pool. In the reracked pool racks are located closer to the wall. The hook of the FH crane will not reach the first row of cells near the North wall and the first two rows of cells near the North wall and first two rows of cells near the East wall. For this purpose a new off set tool will be procured and used. This DCP will also modify the skimmers and strainer and make them removable for future access to the cells directly under these items. New Holtec racks may require use of a funnel for inserting spent fuels. The spent fuel storage capacity will run out in 1998 if this change is not made. After this modification, the storage capacity in the spent fuel pool will be available until 2008 *. There is no reduction in the margin of safety as defined in the basis for any Technical Specification. (SORC 94-056) "Waste Gas System Setpoint Modification" -1. The following setpoints will be verified and adjusted as necessary during DCP installation in order to assure optimum system operation:

1WG8 control, Auto Waste Gas Decay Tank (WGDT) swap-over, Compressor Auto Start and Compressor Auto Stop. 2. A Special Test Procedure (STP) will be created as part of this DCP which will include, but will not be limited to, provisions for optimum test conditions, test procedures, calibrations and adjustments.

Also, steps for adjustments of proportional band and reset for the 11WG22 and 12WG22 controllers will be provided in the STP in addition to the 1WG8 controller.

The goal of this DCP is to maintain a suction header pressure of 0.5 to 2.0 psig as described in UFSAR (Section 11. 3)

SUMMARY

50-272 SALEM 1 AUGUST 10, 1994 R. HELLER (609)339-5162 while operating in the automatic mode. Vendor recommended setpoint changes for the Waste Gas Compressors will be made so that the Waste Gas Compressors can be operated in the automatic mode, as described in the SAR. In addition, the vendor recommended setpoint changes will be used to improve the reliability of the Waste gas Compressors.

The changes performed by this modification to the WGS do not affect any credible failure modes. All plant modifications for this DCP are confined to the recalibration of selected Waste Gas instrumentation.

There no is no increased potential for WGDT rupture since the output of the compressors is reduced in regard to _the design limits of the tanks. The modification involves non-safety related instrumentation and does not involve any Category 1E systems. No active or passive failure modes are associated with this change, and the electrical performance in regard to failure (e.g., hot shorts, grounded shorts, etc.) is not affected by this modification.

There is no reduction in the margin of safety as defined in the basis for any Technical Specification. (SORC 94-060) B. Procedures and Revisions LOCA 3 & LOCA 4 "EOP & FSAR Changes for Recirculation Mode" -There have been several performance issues identified over the years related to the operation of the Residual Heat Removal System (RHRS) during the Recirculation Mode following a Loss Of Coolant Accident (LOCA). These issues include: 1.) Unintended flow paths and their consequences; 2.) Excessive RHRS pump flows during Hot Leg Recirculation; 3.) Excessive suction boost to the Charging/Safety Injection pumps and Intermediate Head Safety Injection pumps. PSE&G and Westinghouse have worked together to develop changes for Salem Units 1 and 2 to address these issues. The scope of this safety evaluation includes an assessment of the following changes: 1.) Modification of the RHR pump design basis for

SUMMARY

50-272 SALEM 1 AUGUST 10, 1994 R. HELLER (609)339-5162 net positive suction head (NPSH) to take credit for Containment air pressure; and 2.) Selected Emergency Operating Procedure (EOP) step changes. The first is necessary to justify an increase in RHR pump "worst-case" maximum flow potential and address Containment Sump level setpoint accuracy.

The changes identified in Item 2 are being made to preclude undesirable RHR pump flow alignments and to enhance RHRS long term availability.

No Technical Specification flow limits are affected by these changes. There is no reduction in the margin of safety as defined in the basis for any Technical Specification. (SORC 94-057) "Performance Indicator Program" -This proposal deletes Nuclear Administrative Procedure NC.NA-AP.ZZ-0034(Z), Performance Indicator Program. The Performance Indicator Program has been incorporated into the Business Plan. The Operational Quality Assurance Program does not apply to this procedure.

Although this procedure is briefly described in the UFSAR (Section 13.5.1 (Hope Creek), Plant Procedures, and Section 13.5.1.1 (Salem), Nuclear Administrative Procedures), it performs no function relative to the safe operation of either Hope Creek or Salem Stations.

Therefore, deleting this procedure will have no affect on the safe operation of either Hope Creek or Salem Stations.

UFSAR Change* Requests for Hope Creek and Salem UFSARs are being concurrently submitted with this proposal to remove the description of this procedure from the UFSAR. This procedure does not affect the operation of any equipment, either safety related or non-safety related. Therefore, deleting this procedure will have no effect on any equipment important to safety. There is no reduction in the margin of safety as defined in the basis for any Technical Specification.

SUMMARY

50-272 SALEM 1 AUGUST 10, 1994 R. HELLER (609)339-5162 "Quality Assurance During the Operations Phase" -The proposed changes: 1.) Reflect current organizational structure; 2.) Make editorial enhancements, and 3.) Provide clarifications.

Additionally, the changes effect selected Quality Assurance (QA) oversight practices for monitoring implementation of the Nuclear Department Procedure System. Changes in QA practices will now utilize the assessment process to evaluate the effectiveness of Nuclear Department groups implementation of the Nuclear Department Procedure System. The assessment approach expands the scope of QA to evaluate process requirements for preparing, reviewing, revising and issuing departmental administrative and implementing procedures.

There are no credible failure modes associated with this change. There is no reduction in the margin of safety as defined in the basis for any Technical Specification. (SORC 94-058}

SALEM UNIT NO. 1 SALEM GENERATING STATION MONTHLY OPERATING

SUMMARY

-UNIT 1 JULY 1994 The Unit began the period operating at full power and continued to operate at essentially 100% power until July 14, 1994, when operators manually tripped the reactor due to loss of all circulators.

An electrical storm in the area caused a bus voltage perturbation which activated the protective relays on the bus feeding the Circulating Water Pumps. A time delay has been installed to prevent a future similar occurrence.

The Unit was returned to 100% power on July 20, 1994, and continued to operate at essentially 100% power throughout the remainder of the period.
