50-311 SALEM 2 JUNE 10, 1993 R. HELLER TELEPHONE: (609)339-2212 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

SUMMARY

A. Design Change Packages 2EE-0016 Pkg 1 11 21 Component Cooling Heat Exchanger Modifications"

- The purpose of this modification is to install a 2 11 drain valve, 21SW241 in the 20 11 service water supply line to 21 Component Cooling Heat Exchanger (CCHX). This valve was to be installed by DCP 2SC-2018, but was not available in time to support implementation of this DCP. A blind flange was installed in place of this valve by MCR 2sc-201a-011, with the valve to be installed at a later date. This valve is a flanged (bolt on) installation, with no welding or system modification of any kind required. Implementation of this DCP will occur during refueling outage Modes 5 or 6 with 21 CCHX out of service. The service water header will be taken out of service and drained down to allow installation of this valve. All applicable Technical Specification requirements will be complied with. This minor configuration change has no effect on the function or reliability of the service water system. Therefore, this DCP does not reduce the margin of safety as defined in the basis for any Technical Specification. (SORC 93-041) 2EC-3216 Pkg 1 "E/C Fitting Replacement" Rev. 2 - The purpose of this DCP is to replace various pipe segments due to normal wear, resulting in pipe wall approaching code minimum thickness values. This DCP replaces existing carbon steel fittings with 2 1/4% Cr - 1%

Mo materials, and, in some cases, heavier wall material. The design requirements of the replaced piping material are not changed and the replacement piping material meets or exceeds the design requirements of the original material specifications. There is no reduction in the margin of safety as defined in the basis for any Technical Specification. (SORC 93-042)

ITEM

SUMMARY

2EC-3148 Pkg 1 "Replace Containment Isolation Valves" - This DCP replaces pressure regulator 2NT31 with a higher range regulator, modify high pressure nitrogen containment isolation valve 2NT32 internals, and modify control air containment isolation valves 21CA330, 22CA330 and high pressure nitrogen containment isolation valves 2NT34 to accept soft seats. All changes are confined to component and do not affect component function. They also remove the external control pressure connection on the 2NT31 nitrogen pressure regulator. Valve 1NT901 will be deleted and valve 2NT54 will be replaced with a higher pressure class valve. There is no change in the function of the valves and the Technical Specification requirements will still be met.

Therefore the proposal does not reduce the margin of safety as defined in the basis for any Technical Specification. (SORC 93-046)

B. Safety Evaluations NFS93-259 "Salem Unit 2 Cycle 8 Reload Safety Evaluation for Operation in all Modes and NRC Notification" - The safety evaluation for operation of Salem Unit 2 Cycle 8 in all modes have been completed and supersede the previous Cycle 8 safety evaluations covering only Mode 6 and Modes 5 & 4, which were presented and approved by SORC on April 22, 1993 and April 29, 1993 respectively. Issues previously identified regarding Auxiliary Feedwater flow rates and Main steam Safety Valve blowdown have been addressed and resolved. The affects that these issues have upon safety analysis inputs were quantified and provided to Westinghouse for incorporation into Cycle 8 safety analyses. The attached safety analyses demonstrate the acceptability of Salem Unit 2 Cycle 8 operation with the current AFW system configuration (up through Mode 2) and with modifications in the AFW and the MSSVs in all Modes. The margin of safety as defined in the Technical Specification bases is not

reduced. The Cycle 8 core design meets all applicable design criteria and ensures that all pertinent licensing basis acceptance criteria are met. (SORC 93-042)

C. Temporary Modifications TMOD # 93-030 "Temporary Modification for lSC-2297 11 - This TMOD installs pressure switches and gages for Unit 2 circulating water pump control, screen wash pressure alarms and to monitor circulating water bearing lube and screen wash header pressure. This TMOD will provided for continued operation of the Unit 2 circulating water pump permissive circuits and the screen wash pump low header pressure alarm circuits. It will also provide for continued monitoring of the circulating water bearing lube screen wash header pressures. This modification does not reduce the margin of safety as defined in the basis for any Technical Specification. This modification increases the margin of safety since the new equipment will maintain the system in the normal operating condition during the installation of lSC-2297. (SORC 93-041)

TMOD # 93-052 "Temporary Circulating Water Bus Tie disconnect Switch" - The purpose of this modification is to install a disconnect switch to provide electrical isolation of Unit 1 and Unit 2 circulating Water Switchgear. This modification does not reduce the margin of safety as defined in the basis for any Technical Specification. This modification only installs a temporary disconnect switch to provide electrical isolation required during the installation of DCP lSC-2297. (SORC 93-041)
