FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTl!l!/YEAR.: DECEMBER 1990 DCP 88-01 INSIDE RECIRCULATION SPRAY PUMP FULL FLOW TEST LINE UNIT 1 This Design Change provides recirculation test piping and a temporary sump to allow full flow testing of the IRS pumps. The piping was designed to ANSI B31.l code requirements and includes flow and pressure instrumentation to meet ASME XI requirements for pump testing.

The recirculation test piping and temporary sump will be connected/installed during Unit shutdown conditions only. This modification will not affect the operation of the safety-related IRS pumps. It will not affect the design basis of the IRS system to mitigate LOCA or SLB accidents. The modified IRS pump discharge piping will meet the original station design criteria.

This modification increases the reliability of the IRS pumps since the periodic testing will be used to assess the flow capacity and operational readiness of the pumps.

The only permanent change to the IRS system piping installed under this design change is the addition of a flanged spool piece in the pump discharge line. This piping section has been designed to meet safety related and seismic requirements. There are no valves installed in the pump discharge piping which could be misaligned (closed) and prevent initiation of spray flow.

Therefore, an unreviewed safety question is not created.

EWR-89-713 ENGINEERING WORK REQUEST UNITS 1&2 12/01/90 (Safety Evaluation #N89-0036)

The valve operator spring precompression for valve l/2-RC-PCV-1455/2455 A&B will be increased such that the valve will begin to operate at 40 PSIG versus the current setting of 38 PSIG.

The increase of valve operator spring precompression is required to prevent the valve from being forced opened due to Reactor Coolant Spray (RCS) pressure during PT-11 testing and to provide additional seating force margin during normal operations. An unreviewed safety question does not exist because the design basis operation, function and level of integrity of the valves remains unchanged.

e e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTI:ll/YEAR: DECEMBER 1990 EWR-89-042 ENGINEERING WORK REQUEST UNIT 1 12/02/90 An electrical cable, l-CC-TC-114A, in the Component Cooling system was damaged and required replacement with a different qualified cable type.

An existing cable, mark number NVB, is to be replaced with a new cable, mark number NGB-35. Both cables are one pair, number 16 AWG, shielded. Only the jacket material is different. An unreviewed safety question is not created.

EWR-89-458 ENGINEERING WORK REQUEST UNIT 1&2 12/02/90 During recent testing of the Bottled Air System, the existing pressure control valves, l-VS-PCV-531/532, functioned erratically and did not properly provide the design flow rate of 300 cfm.

To assure that the design flow rate is achieved, new Fisher pressure control valves were installed as replacements. The consequences or probability of an accident were not created due to the component replacement with safety related equipment which performs in accordance with design basis requirements.

EWR-89-529 ENGINEERING WORK REQUEST UNITS 1&2 12/03/90 This request was performed to reduce spurious alarms being received on the Chemical and Volume Control System (CVCS) heat trace annunciator in the control room.

CVCS heat trace annunciator under temperature setpoint and backup control setpoints are being reviewed and reset to eliminate spurious alarms. No changes are being made to the existing equipment and the alarm will continue to communicate problems associated with the eves heat tracing. An unreviewed safety question is not created.

TM-Sl-90-052 TEMPORARY MODIFICATION (SE 90-288) 12-04-90 This temporary modification installed a test plug. The Type 'C' test valve used for penetration leak testing of the 0-rings for an electrical penetration was broken off and temporarily replaced with a test plug until the valve was replaced.

Containment integrity continued to be met during this installation. The test plug only replaces the valve which is used to perform the 0-ring leakage testing. The plug does not affect the ability of the 0-ring/flanges to perform their pressure retaining functions. An unreviewed safety question was not created.

10

FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH:l!/YEAR: DECEMBER 1990 EWR-88-587 ENGINEERING WORK REQUEST UNITS 1&2 12/06/90 This request provided generic guidance for Motor Operated Valve maintenance on spring packs. The request also established a record of correct assembly of spring packs after disassembly and cleaning.

This request does not create an unreviewed safety question.

SAFETY EVALUATION (SE 90-289) 12-06-90 This safety evaluation analyzed the loading of known failed fuel assemblies in dry storage casks. The evaluation examined the known effectiveness of vacuum drying to remove water from failed rods and the potential for release of radioactive isotopes from the fuel rod gap during the drying process. As a related issue, the release of radioactive isotopes resulting from the failure of a fuel rod during the vacuum drying of the cask cavity was evaluated.

An unreviewed safety question does not exist because the vacuum drying process for dry storage casks is effective in removing any water from the gap of the failed fuel rods. In addition, gas isotopes will not be present in the gap of failed fuel rods at levels detectable during the vacuum drying process. If a fuel rod should fail during vacuum drying, the release of Kr-85 would result in calculated doses of 0.36 rn.Rem (skin) and 0.004 mRem (whole body) at the Station Boundary.

AC-Sl-90-1207 ADMINISTRATIVE CONTROL (SE 90-290) 12-07-90 Administrative Control was established over certain normally closed and locked manual containment isolation valves while in an open position to allow supply of instrument air from the turbine building Instrument Air system. Administrative control will be established to ensure that containment integrity can be maintained in accordance with the Technical Specification (TS) definition in TS 1.0. Specifically, an operator will be stationed with instructions to close the valves immediately (within 30 seconds) upon notification from the control room. In addition, the administrative control will ensure the ability to maintain the limits for containment partial pressure in accordance with the limits of TS 3.8. Therefore, an unreviewed safety question is not created.

11

e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONT.lffi/YEAR: DECEMBER 1990 TM-Sl-90-59 TEMPORARY MODIFICATION (SE 90-292A) 12-16-90 Electrical jumpers will be installed to provide continuity through the low flow reactor trip circuitry during replacement of relay FC-434XA. The jumper is required to maintain train 'A' low flow circuitry in the energized condition while normal continuity is broken for relay replacement.

Replacement of relay FC-434XA using this jumper will affect only Train 'A' reactor trip circuitry. Further, the jumper will provide electrical continuity through the Train 'A' circuitry and failure of the jumper will result in a reactor trip.

Therefore, an unreviewed safety question is not created.

TM-Sl-90-60 TEMPORARY MODIFICATION (SE 90-293A) 12-17-90 This temporary modification is necessary to provide an electrical jumper to allow replacement of a failed relay in the reactor protection circuitry. Replacement of the relay is necessary to provide the third operable reactor protection system circuit for RCS low flow. Failure of the jumper will result in a reactor trip. The jumper will be removed before unit startup. Therefore, an unreviewed safety question is not created.

TM-Sl-90-61 TEMPORARY MODIFICATION (SE 90-293) 12-17-90 Electrical jumpers will be installed to provide continuity through the low flow reactor trip circuitry during replacement of relay FC-lXB. The jumper is required to maintain train 'B' low flow circuitry in the energized condition while normal continuity is broken for relay replacement.

Replacement of relay FC-lXB is necessary to provide redundant relay failure protection for RCS Loop 'A', Train 'B' RPS low flow protection logic. The jumper will maintain the RPS circuitry energized during relay replacement. Failure of the jumper will result in a reactor trip. Therefore, an unreviewed safety question is not created.

12

PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: DECEMBER 1990 l-PT-18.3A SURVEILLANCE TEST PROCEDURE (SE 90-291) 12-09-90 This change involved the testing methodology employed for testing the Safety Injection (SI) system check valves to the RCS cold legs. The change allowed the testing of the valves at full flow conditions with the RX head bolted.

The integrity of the RCS was the major issue evaluated. RCS temperature effects were evaluated by the NSSS vendor (Westinghouse). During the test 45 degree Fahrenheit water from the RWST will be injected into the RCS at a rate of 600 gpm at CSD conditions. The evaluation concluded that the Over Pressure Mitigation System (OPMS) and Technical Specification requirements for OPMS operation (TS 3.1.G) can be relied upon to relieve RCS pressure during the test in combination with establishing an atmospheric vent for the RCS prior to the test.

Plant operators have instructions to terminate the test if pressurizer level exceeds 80% to avoid solid plant conditions.

Therefore, an unreviewed safety question is not created.
