DCP 94-021 DCP 93-075-3 DCP 92-68-3 DCP 94-056 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR:

March, 1995 Design Change Package (Safety Evaluation No.94-114) e Surry Monthly Operating Report No. 95-03 Page 10 of 19 3-02-95 Design Change Package 94-021 de-terminated the unused average temperature -input signal to the Rod insertion Limit modules. The signal is not used in the development of the Rod Insertion Limits. Disconnecting the unused wiring will not affect the average temperature input signal to the Rod Control, Pressurizer Level, Steam Dump or Feedwater Isolation systems. The change will eliminate electrical cross-talk that causes a spurious annunciation following an operational switching evolution.

Since the input is unused and no safety related functions are affected, an unreviewed safety question does not exist. Design Change Package (Safety Evaluation No.93-228) 3-02-95 Design Change Package 93-075 replaced the Steam Generator (SG) Channel Head Drain Lines utilizing butt welded joints. The previous joints were socket welded. The use of butt welded joints eliminates the corrosive environment in the joints of the drain lines. The replacements were performed at cold shutdown conditions and the SG was drained. The modification improves the reliability of the drain line welded joints and therefore does not represent and unreviewed safety question.

Design Change Package (Safety Evaluation No.93-190) 3-03-95 Design Change Package 92-068 installed a bypass line with a flow restricting orifice around certain main steam check valves in steam supply piping to the steam driven auxiliary feedwater (AFW) pump turbine for Unit 1 and Unit 2. The change is designed to eliminate damage induced by low flow conditions which cause chattering of the check valves resulting in damage to the valves. The design will allow a limited bypass flow around the check valve to prevent the chattering.

The bypass lines do not affect the ability of the AFW pump to perform their safety function.

The reliability of the check valves will be improved.

The lines are fabricated in accordance with the appropriate codes and standards.

Therefore the design change does not represent an unreviewed safety question.

Design Change Package (Safety Evaluation No.93-182) 3-06-95 Design Change Package 94-056 connected the compensating lead to one of the two normal leads for Unit 2 Reactor Coolant System (RCS) "C" 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.

TM 82-95-03 TM 82-95-04 e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR:

March, 1995 Temporary Modification (Safety Evaluation No.95-031) Surry Monthly Operating Report No. 95-03 Page 11 of 19 3-07-95 Temporary Modification (TM) 82-95-03 removed inside trip valve 2-DA-TV-200A"for maintenance, installed a spool piece to maintain an operable flowpath from the Unit 2 containment sump pumps 2-DA-P-4A/B, and maintained an operable flowpath for the containment sump sample pump. Installation of electrical jumpers allowed 2-DA-P-4A/B to operate with the limit switches for 2-DA-TV-200A removed. This activity will not affect the operability of the containment sump pumps, nor the operability of the containment sump sample pump. Leakage into the containment due to spool piece failure could be isolated by the pump discharge valves and the outside trip valve 2-DA-TV-2008.

Containment integrity is not required by Technical Specification (TS) 3.8 when the Unit is at COLD SHUTDOWN.

If refueling integrity is required in accordance with TS 3.10, 2-DA-TV-2008 can be maintained operable or closed. This TM is required to be removed prior to exceeding 200°F. Since the system will be returned to its design condition following repairs and prior to operation, an unreviewed safety question does not exist. Temporary Modification (Safety Evaluation No.95-032) 3-07-95 Temporary Modification (TM) 82-95-04 will remove the Unit 2 "B" Circulating Water (CW) pump upper guide bearing alarm module which is inoperable and must be removed from the alarm circuit to be repaired.

In order to maintain the remainder of the alarm module circuits operable while the module is being removed, a jumper will be installed between thermocouples TC-CW-201 C and TC-CW-200C.

When the module is removed, the 200C and 201 C leads will be shorted together to restore and maintain circuit continuity.

The module alarm functions do not provide any control or interlock functions for the CW pump motor supply breakers and will not prevent the start or cause the trip of a CW pump. Since the components affected by this activity perform no protective or mitigating functions and are not part of the safety-related Emergency Service Water pump controls, an unreviewed safety question is not created.

TM S2-95-06 TM S2-95-05 TM S2-95-07 e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR:

March, 1995 Temporary Modification (Safety Evaluation No.95-033) Surry Monthly Operating Report No. 95-03 Page 12 of 19 3-08-95 Temporary Modification (TM) S2-95-06 will remove the Unit 2 "A" Circulating Water (CW) pump upper guide bearing alarm module which is inoperable and must be removed from the alarm circuit to be repaired.

In order to maintain the remainder of the alarm module circuits operable while the module is being removed, a jumper will be installed between thermocouples TC-CW-201 A and TC-CW-200B.

When the module is removed, the 200B and 201 A leads will be shorted together to restore and maintain circuit continuity.

The module alarm functions do not provide any control or interlock functions for the CW pump motor supply breakers and will not prevent the start or cause the trip of a CW pump. Since the components affected by this activity perform no protective or mitigating functions and are not part of the safety-related Emergency Service Water pump controls, an unreviewed safety question is not created. Temporary Modification (Safety Evaluation No.95-034) 3-09-95 Temporary Modification (TM) S2-95-05 will replace relay 2-RP-RL Y-TTXA. Three jumpers are required to perform this task. Two of the jumpers will provide closed contacts to the steam dump and turbine trip circuits during the relay replacement in order to maintain the relay's output signal. The third jumper is used to keep the train "A" reactor protection circuit intact during the relay replacement.

This task will be performed on train "A" only while train "B" will remain unaffected during relay replacement.

The module alarm functions do not provide any control or interlock functions for the CW pump motor supply breakers and will not prevent the start or cause the trip of a CW pump. Since Unit 2 will be at COLD SHUTDOWN with the reactor trip breakers open while the work is performed, an unreviewed safety question is not created. Temporary Modification (Safety Evaluation No.95-035) 3-09-95 Temporary Modification (TM) S2-95-07 will install electrical jumpers to allow manual operation of the containment sump pumps 2-DA-P-4A/B.

Also this activity will defeat the low level cutoff for 2-DA-P-4A/B and local sump level observation will be required during the pumping evolution.

Operability of the sump pumps is not affected by this maintenance activity since manual operation is an original design feature. Sump pump and level indications will be restored prior to exceeding 200°F. Since the system will be returned to its design condition following repairs and prior to operation, an unreviewed safety question does not exist.

DCP 94-009 DCP 91-06-2 SES95-037 e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR:

March, 1995 Design Change Package (Safety Evaluation No.94-128) Surry Monthly Operating Report No. 95-03 Page 13 of 19 3-10-95 Design Change Package 94-009 changes the thermal overloads for a number-of safety related motor operated valves (MOVs) to a different size and setting to assure operation of the MOV under conditions in accordance with the requirefl1ents of Generic Letter (GL) 89-10. The change implements industry standards to assure that the thermal overloads are set to assure that the MOV motor will not experience failure as a result of operation during accident conditions.

The change will improve the reliability of the MOV by improving the ability for the MOV to be operated additional times. This change does not affect the ability of the valve to perform its safety function or reduce the margin of safety. Therefore, an unreviewed safety question is not created. Design Change Package (Safety Evaluation No.92-190) 3-12-95 Design Change Package 91-06-2 removed the Unit 2 resistance temperature device (RTD) bypass piping system and replaced it with thermowell mounted RTDs directly in the RCS hot and cold leg pipes. The modification did not degrade the performance or increase the challenges to equipment assumed to function during an accident condition.

Therefore, an unreviewed safety question did not exist. Safety Evaluation 3-17-95 Safety Evaluation S95s037 assessed the acceptability of "as-left" leakage testing results for valves in piping from the refueling water storage tank (RWST) and the high head safety injection pump suction prior to commencing startup following Unit 2 refueling.

The leak rate results were found to be unacceptably high by current 1ST test criteria in 2-0PT-81-012. This condition provides a leak path back to the RWST during Post-LOCA conditions when the Safety Injection System is operating in Recirculation Mode Transfer.

The evaluation concluded that additional back leakage to the RWST will not have a significant effect on on-site and off-site doses. However, local radiation doses may be higher in the vicinity of the subject piping. Existing post-accident HP practices will ensure increased radiological monitoring of potentially affected components.

The probability of a large break LOCA will not be affected by the as-left leak rates. The as-left leakage is bounded by existing calculations.

Based on a licensing design basis review, the check valve 2-81-25 may be used as single isolation for the RWST and its failure to open or close is not considered credible.

Therefore, an unreviewed safety question does not exist.

SE 95-038 DCP 93-017 e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR:

March, 1995 Safety Evaluation Surry Monthly .Operating Report No. 95-03 Page 14 of 19 3-18-95 Safety Evaluation 95-038 assessed the continued operation of Residual Heat Removal (RHR) System suction isolation valve 2-RH-MOV-2701-with its torque switch inoperable in the closing direction.

This valve is a normally closed de-energized valve in series with 2-RH-MOV-2700 to provide isolation from the 'A' Loop Hot Leg. The operation of 2-RH-MOV-2701 is enabled on decreasing RCS pressure sensed by a pressure transmitter.

A jumper was installed around a limit switch contact and a torque switch contact to fully close the isolation valve, and then removed. No other limit switches were affected by this activity.

The postulated malfunction for this valve is failure to open. Neither the capability of this valve to open, nor the pressure interlock which prevents the opening of this valve will be affected.

The capability of the RHR system to perform its function is likewise not affected.

Therefore, the reliable operation of the valve has been maintained, and an unreviewed safety question does not exist. Design Change Package (Safety Evaluation No.93-118) 3-21-95 Design Change Package 93-017 modified the Unit 1 and 2 condenser inlet circulating water motor operated valves (MOV) to qualify them for operation while submerged.

The modifications are considered a plant design enhancement that will improve isolation capability during a postulated flood and will provide additional operational flexibility.

The modifications did not change the function, operation, or performance of the MOVs or the circulating water systems. Therefore, an unreviewed safety question does not exist.

2-EPT-0903-01 CH-31.940 e Surry Monthly Operating Report No. 95-03 Page 15 of 19 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR:

March, 1995 Electrical Periodic Test (Safety Evaluation No.95-030) 03-07-95 Temporary modifications will be implemented to facilitate testing of the containment fire detectors in each reactor coolant pump cubicle. The fire detector element leads and alarm output leads will be lifted and test equipment installed to test the circuit. The fire detector control module is tested by simulating the detector element and verifying the actuation of the alarm to the control box for annunciation in the control room. System operation is verified upon removal of the test equipment by pushing the local test button on the control panel to ensure circuit continuity, and by monitoring the alarm response in the control room. To ensure that a fire in the RCP cubicles during the test would be detected, a Technical Specification limiting condition for operation will be entered that requires monitoring of the RCP pump bearing and motor temperature or containment RTDs during performance of the procedure on an hourly basis, or perform containment walkdowns once every eight hours. This will ensure a fire in the RCP cubicle will not go undetected.

Therefore, an unreviewed safety question does not exist. Chemistry Procedure (Safety Evaluation No.95-040) 03-23-95 To enable chemicals to be added to the Component Cooling System in a more efficient manner, a mobile chemical addition system will be attached to the component cooling heat exchangers outlet header drain valve 1-CC-1179.

The chemical addition system includes a pump, hose, tank and discharge check valve. The pump is rated at a discharge pressure of 150 psig, which is well above normal CC operating pressure.

The installed check valve prevents back leakage from the CC system and the procedure requires personnel to be at the pump during any pumping operations to ensure the pump does not lose suction. Condensate quality makeup water will be used to flush the chemical addition tank, which is normal makeup to the CC system. Therefore, an unreviewed safety question does not exist.
