PAGE 10 OF 21 e.

.F ACIUTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR FEBRUARY 1988 T-MOP-2007 REPLACEMENT OF RV-BR-109 02-12-88 This temporary operating procedure involved the temporary hookup of fill and vent hoses from the gas stripper feed heat exchangers (HX) to the overhead gas compressors suction to evacuate the stripper feed HX while RV-BR-109 was replaced.

This change will not have an effect on the volume control tank (VCT) or waste gas decay tank (WGDT) rupture analyses as the gas concentration and release rates are unaffected and no condition exists wherein the relief capacities of the tanks relief devices are exceeded.

TM-Sl-88-3 TEMPORARY CCW MAKEUP SUPPLY FROM PG 02-01-88 A temporary modification connected a hose from a primary grade water service connection to a connection at the component cooling water (CCW) pump suction header in order to work l-CD-372.

Since a source of makeup is provided to CCW system and CCW remains operable and reliable, accidents are not affected or created.

TM-Sl-88-06 TRANSFER OF ION EXCHANGE RESIN 02-23-88 A temporary modification installed a fitting and flexible hose for transfer of ion exchange resin.

This modification does not constitute an unreviewed safety question because its probability of failure was not increased (due to appropriate pressure rating of components and pre-use testing of installation) and consequences of failure are previously evaluated.

TM-S2-88-8 ADMINISTRATIVE CONTROL OF TV-SS-202A & TV-SS-202B 02-02-88 11 This temporary modification failed closed (by lifting solenoid valve leads and isolating instrument air) and placed under administrative control the sample trip valves TV-SS-202 A/B.

No unreviewed safety question exists due to this modification because alternate PASS flowpaths via RHR sample lines, RCS - Loop Hot Leg Sample lines and eves demineralized sample lines will remain available.

PAGE 11 OF 21 e.

FACILJTY CHANGES THAT DID NOT REQUIRE NRG APPROVAL MONTH/YEAR FEBRUARY 1988 TM-S .2-88-10

• CORROSION PRODUCT STUDY 02-25-88 A temporary modification installed sampling lines for the following Unit 2 components/systems: A and C blowdown, feedwater, and 2A feedwater heater.

No

• unreviewed safety question exists due to this modification since additional sampling lines do not increase probability of tube rupture and consequences of main steam line rupture are previously analyzed*

. SP-88-08 PLANT COASTDOWN 02-25-88 Setpoints of various plant instruments* were changed to allow an end of cycle plant coastdown.

Accidents and equipment were reviewed for the proposed average temperature. Proposed reduction was within previously reviewed range resulting

• in no unreviewed safety question.

SCAFFOLD REQUEST 02-10-88 A temporary scaffold platform was constructed in the Unit 2 Main Stearn valve house at 27 1 elevation to work on 2-MS-176 (steam supply check valve to 2-FW-P-2).

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability/function. Conclusion is that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

I I

ADMINISTRATIVE CONTROL OF CH HEAT TRACING 02-22-88 !

Heat tracing circuit 2Al-25 (CH) was placed under administrative control to provide increased surveillance of the heat tracing circuit and, if required, manual operation of the circuit to maintain temperature within the required band.

Manual control of CH heat tracing does not constitute an unreviewed safety question because it will be under administrative control ensuring that fluid temperatures are maintained between l 20°F and l B0°F.

PAGE 12 OF 21 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL e .

MONTH/YEAR FEBRUARY 1988

. SCAFFOLD REQUEST 02-23-88 A temporary scaffold. platform was constructed in the Auxiliary Building at ten feet elevation to work a vertical ladder.

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability/function. Conclusion is that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

SCAFFOLD REQUEST 02-23-88 A temporary scaffold platform was constructed in the Auxiliary Building at five feet elevation to work on a vertical ladder.

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability/function. Conclusion is that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

• SCAFFOLD REQUEST 02-26-88 A temporary scaffold platform was constructed in the Turbine Building Basement .at nine feet elevation to work on 1-CW-MOV-lOOA.

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability/function. Conclusion is that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

PAGE 13 OF 21 PROCEDUREORMETHOI> OF-QPERATION-GHANGES THAT-DID NOT-REQUIRE NRG APPROVAL MONTH/YEAR FEBRUARY 1988 EMP-P-RT-13 PROTECTIVE RELAY MAINTENANCE FOR CB I5Hl 02-25-88 A procedure deviation was approved to place the H and J bus cross connect breaker in test to perform the preventive maintenance procedure while at power; Placing the H and J cross_ connect breaker in test while at power will have no effect on the H & -J buses because the breaker will not be placed in the connect position; IMP-C-RPI-32 ROD POSITION INDICATION SYSTEM MAINTENANCE UNIT 2 02-10-88 Procedure deviation to allow use of the Prodac 250 computer to monitor control bank 'B' rod positions during repair of benchboard !RPI.

• Control rod position indication from the P-250 computer is an acceptable substitute for benchboard !RPI provided that T.S. 3~12.E is complied with and duration of substitute is minimized.

MOP-12.4 RETURN OF RM-SS-113 TO SERVICE UNIT-I 02-16-88 Procedure deviation to align blowdown of two steam generators (B & C) through RM-SS-113 which contradicted UFSAR 11;3;3~8; UFSAR 11~3;3~8 states that all three steam generator blowdown flows are through one radiation monitor~

Changing the UFSAR assumed alignment of steam generator blowdown flow through the radiation monitors enhances the ability to detect primary-to-secondary leakage. Therefore; SGTR accident analyses and consequences are not adversely affected;
