IOCFR50.59 EVALUATIONS DOCKET NO:,;,,: 50-311 MONTH: MARCH 1995 UNIT NAME: SALEM2 DATE: 04/10/95 COMPLETED BY:* R.HELLER TELEPHONE: 609-339-5162 The following items were evaluated in accordance with the provisions of the Code of Federal Regulations IOCFR50.59. The Station Operations Review Committee has reviewed and concurs with these evaluations.

I. Design Change Packages (DCP) 2EE-0088, Pkg. I No. 22 Charging Safety Injection Pump Inboard Mechanical Seal Housing Replacement" Rev. 0 - This DCP entails the replacement of a leaking inboard mechanical seal assembly and seal housing on No. 22 Charging Safety Injection (C/SI) pump. The seal housing of the new replacement mechanical seal assembly, which is a later design, does not have jacket water cooling connections or a design requirement for these cooling connections. As noted in a Dresser Pacific (pump manufacturer) letter dated 8/24/84, the later design seal housings were revised to eliminate the cooling water jackets in 1976 and all pumps manufactured since have no seal housing water jackets. At this time, the proposed change to 22 C/SI pump will not change the outboard mechanical seal which still has active connections for cooling the seal housing. The operability and reliability of the C/SI pump is not affected by the installation of the replacement seal assembly. The acceptance criteria for the design basis accidents continues to be met and the margin of safety as defined in the Technical Specifications is unchanged. (SORC 95-025) 2EC-3352, Pkg. I "Waste Gas Setpoint Modification" Rev. 0 - This DCP changes the waste gas setpoints* to vendor recommended values. The overall task of this DCP is to implement the necessary setpoint and piping changes to allow stable continuous Waste Gas Compressor operation with full recirculation capability. All plant modifications for this DCP are confined to recalibration of selected Waste Gas instrumentation and rerouting of existing compressor recirculation piping. There are no additional failure modes

The Waste Gas System setpoints, compressor recirculation line, compressor output capacity and WGDT storage volume, which are changed by this DCP, are not specifically addressed in the Technical Specifications. There is no reduction in the margin of safety as defined in the bases for any Technical Specification.

(SORC 95-028) 2EC-3303, Pkg. 1 "Circulating Water Bearing Lubrication Screen Wash Setpoint & System Changes" Rev. 0 - Rev. 0 - The plant modifications to be accomplished under this DCP include:

1) recalibration of header pressures and flows of the Circulating Bearing Lubrication system and the Screen Wash system, 2) Lubrication Pump and Screen Wash Pump strainer control changed from timed to continuous, 3) replacement of the lubrication water and screen wash pressure gages, and, 4) replacement of control valves with manual valves to simplify the system. The affected components do not change in regard to their function. No new failure modes will be introduced by these modifications.

There is no reduction in the margin of safety as defined in the basis for any Technical; Specification. (SORC 95-032)

2. Temporary Modifications (T-Mods)95-022 "Boric Acid Evaporator Level Transmitter Replacement" Rev. 0 - The T-Mod will replace the level transmitter with one that does not have a sealed reference leg. The modified instrument and process sensing line will have a configuration like the 1LT3 l 5 on the Unit 1 Boric Acid Evaporator {BAE). The tubing that will now contain process fluid will be heat-traced to prevent crystallization of the boric acid, ensuring that the line does not get clogged thus rendering the instrument inoperable. The tubing for this part of the BAE is Schedule SP33C, which is non-safety related, non-nuclear, and seismic III. The operation and

HELLER TELEPHONE: 609-339-5162 control of the BAE will not be changed because of this temporary modification. No procedure changes are required. The BAE is non-safety related equipment. Neither the BAE or any associated equipment is addressed any Technical Specifications or their bases. In addition, there is no credible way in which the PASS would be affected by this*T-Mod. Thus the margin of safety is unaffected.

(SORC 95-027)

3. Safety Evaluations (S/E)

S-2-SW-MSE-0848 "Salem Unit 2 Service Water Pump Fastener Material" Rev. 0 - This S/E addresses concerns pertaining to fasteners used on four Salem Unit 2 Service Water (SW) pumps. The conditions became apparent through Problem Report No.

950119152 which described the potential for Service Water pumps having stainless steel (SS) fasteners in place of the Monel fasteners originally supplied in the pumps. The fasteners have been found to be acceptable for short term use, as discussed in this evaluation. Therefore, the condition does not reduce the margin of safety as defined in the basis for any Technical Specification. Being that the design integrity of the four applicable SW pumps is maintained and the remaining two pumps have the correct fasteners, operability of the six SW pumps is not affected by this condition. (SORC 95-031)

SALEM GENERATING STATION MONTHLY OPERATING

SUMMARY

- UNIT 2 MARCH 1995 SALEM UNIT NO. 2 The Unit began the period shutdown while No. 21 Reactor Coolant Pump seal replacement was in progress. The repairs were completed and the Unit was synchronized to the grid on 03/09/95. On 03/10/95, the power escalation was held at 81% to perform scheduled post outage testing. In addition, Nos. 22 & 23 Heater Drain Pumps (HDP) were out of service for repairs, delaying power escalation. Repairs to No. 23 HDP were completed and power was increased to 95% on 03/12/95. No. 22 HDP was returned to service and power was increased to 95% on 03/15/95. On 03/16/95, power was reduced to 77% due to the influx of grass and problems with the circulating water pump screens.

On 03/18/95, power was administratively limited due to a meadow fire underneath the Keeney Line. The line had been removed from service and required a load reduction due to system loading restrictions. Power was increased to 96% on 03/19/95, and held at 96%

to collect state point data. On 03/19/95, power was reduced to investigate problems with No. 22 Steam Generator Feed Pump (SGFP) controls. The Unit was returned to 96%

power on 03/21/95, however, No. 21 SGFP speed oscillations occurred and power was reduced to 50% on 03/23/95. The Unit continued to operate at 50% power throughout the remainder of the period, while the investigation into the SGFP control problems continued.
