• FACILITY CHANGES THAT DID NOT tlurry Monthly Operating Report No. 94-12 Page 11 of 19 REQUIRE NRC APPROVAL MONTH/YEAR: December, 1994 DR S-94-2132 Deviation Reports 12-06-94 DR S-94-2138 (Safety Evaluation No.94-208)

Safety Evaluation 94-208 assessed the condition addressed by Deviation Reports S 2132 and S-94-2138 concerning the operation of Unit 1 with hot leg loop stop valve 1-RC-MOV-1594 fixed on its backseat with the disc assembly wedged between the seat ring and the backseat.

A UT examination was performed on the hot leg loop stop valve to ensure the stem' was free of cracks. The valve manufacturer was contacted and concurred that no additional valve damage would result from leaving the valve in the fixed position during unit heat-up and operation. The subject configuration was determined to be acceptable since the loop stop valves are used for maintenance isolation and are not required for accident mitigation. Therefore, an unreviewed safety question does not exist.

TM S1-94-038 Temporary Modification 12-06-94 (Safety Evaluation No.94-210)

Temporary Modification (TM) S1-94-038 failed Primary Drains Transfer Tank (POTT) pressure control valve, 1-DG-PCV-100, in the open position to eliminate spurious High Flux at Shutdown alarms caused from electrical noise generated when 1-DG-SOV-100 energizes to open 1-DG-PCV-100.

The TM was in place while the unit was at Cold Shutdown (CSD) with the containment at atmospheric conditions. At these conditions, the Primary Drains System functioned normally. Containment isolation capability was maintained and unaffected by this TM.

Therefore, an unreviewed safety question did not exist.

DR S-94-2248 Deviation Report 12-16-94 (Safety Evaluation No.94-211)

Safety Evaluation 94-211 assessed the condition identified by Deviation Report S 2248 concerning the induction of pieces of 1.5 inch rubber hose ~ six inches per steam generator) into the secondary side of the Unit 1 steam generators (SG) during the SG chemical cleaning process.

An evaluation of Unit 1 operation with the SGs containing the foreign objects was performed by Westinghouse Nuclear Safety. The evaluation concluded that the presence of the objects is not expected to have an adverse effect on the primary pressure boundary integrity of the SGs. Therefore, an unreviewed safety question does not exist.

tlurry Monthly Operating Report No. 94-12 Page 12 of 19 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: December, 1994 FS 94-01 Updated Flnal Safety Analysls Report Change 12-19-94 (Safety Evaluation No.93-212)

UFSAR Change 94-01 revised Section 6.3, "Consequence-Limiting Safeguards,n to identify the types of fibrous material used inside containment and added a section to discuss how the containment design reduces the potential for significant debris buildup on the containment sump screens during a loss of coolant accident or high energy line break.

This change was administrative in nature and did not involve any physical changes to the plant. Therefore, an unreviewed safety question does not exist.

DCP94-56 Design Change Package 12-23-94 (Safety Evaluation No.93-182)

Design Change Package 94-56 connected the compensating lead to one of the two normal leads for Unit 2 Reactor Coolant System (RCS) "Cn hot leg wide range temperature indication spare element, 2-RC-TE-2433-2. This configuration allows the compensating lead to be used in lieu of a failed normal lead, enabling 2-RC-TE-2433-2 to be returned to service.

The associated transmitter was adjusted, based on previous measurements, to offset the change in lead resistance and ensure the accuracy of the subject temperature indicator.

This modification did not affect other RCS temperature indication. Therefore, an unreviewed safety question does not exist.

DCP88-24 Design Change Package 12-30-94 Design Change Package 88-24 modified or replaced various indicators, recorders, and controllers in the Main Control Room and Emergency Switchgear Room to correct Human Engineering Deficiencies (HED).

These modifications correct HEDs identified during the Control Room Design Review that was required by NUREG-0737. Implementation of these modifications did not affect the operation of safety-related equipment or systems or the availability of safety-related power sources. Therefore, an unreviewed safety question does not exist.

DCP93-53 Design Change Package 12-30-94 (Safety Evaluation No.94-142)

Design Change Package 93-53 corrected Human Engineering Deficiencies (HED) including the labeling of the auxiliary shutdown panel, certain heat tracing, and emergency diesel generator switches and indicators and respective panels. The titles of certain control room status tiles were also changed to improve clarity.

These modifications correct HEDs identified in the Control Room Design Review Reassessment Report that was required by NUREG-0737. Implementation of these modifications did not affect the operation of safety-related equipment or systems or the availability of safety-related power sources. Therefore, an unreviewed safety question does not exist.

Temporary Modification (TM) S1-94-39 installed an individual rod position indication (IRPI) rod bottom bistable module with a soldered jumper which defeats the IRPI dropped control rod turbine runback and rod stop for Unit 1 control rod K-2. This modification will prevent a spurious turbine runback and allow continued operation of Unit 1.

Other IRPI turbine runback and rod stop circuits, as well as nuclear instrument, over-pressure delta temperature and over-temperature delta temperature turbine runback and rod stop circuitry remain operable while this modification is installed. Therefore, an unreviewed safety question does not exist.

Operations Periodic Test Procedures 1-0PT-Sl-005 and 2-0PT-Sl-005, "LHSI Pump Test" were temporarily revised to permit the use of temporary transmitters to enable the measurement of low head safety injection pump discharge pressure during the few seconds following pump start.

The use of the temporary safety-related transmitters does not affect the operation of the subject pumps or the ability of the safety injection system to perform its required safety function. Therefore, an unreviewed safety question does not exist.
