FACIIJTY CHANGES REQUIRING NRG APPROVAL MONTH/YEAR JANUARY 1988 NONE DURING THIS PERIOD

F ACIUTY .NGES THAT DID NOT REQUIRE C APPROVAL MONTH/YEAR Jartuary 1988 EW.R 87-331 ADDITION OF FP CARDOX ODORIZER UNITS 1 & 2 1/29/88 This engineering work request added an odorizer to the Cardox System to enhance worker safety by providing another means of detecting a discharge of the system.

The addition of odorizers does not effect the function of the Cardox System. Therefore, the enhancement does not impact plant or public health and safety nor result in an unreviewed safety question.

EWR 87-400 REPLACE MAIN STEAM VALVE (1-MS-104) UNIT 1 1/12/88 This engineering work request installed an equivalent safety related gate valve to replace l-MS-104, an isolation globe valve for the auxiliary feedwater pump steam flow transmitter which had a bonnet steam cut.

The replacement valve is of the same pressure class and material as the original valve. Therefore, there are no changes in the probability or consequences of accidents analyzed in the UFSAR, nor has the possibility of a new accident being created. The margin of safety is not affected.

EWR 87-403 MODIFY FEEDWATER VALVES UNITS 1 & 2 1/05/88 (1/2-FW-MOV-lSOA, B/250A, B)

This engineering work request evaluated modifications to the Unit 1 and 2 feedwater pump discharge valves (1-FW-MOV-150 A/B and 2-FW-MOV-250 A/B) to prevent the operator mounting studs from pulling loose from the operator body.

The installation of: 1) all thread rod studs to ensure thread engagement, 2) one new stud between existing holes for support and 3) a new yoke flange will not result in an unreviewed safety question.

EWR 87-410 EVALUATE GLAND BOLT MATERIAL CHANGE 1/05/88

{1-CH-163, 164) UNIT 1 This engineering work request compared chemical and* mechanical properties of the old (A 19 3) and the new (A582) gland bolt materials for Westinghouse valves (2 11 - T58) to determine if the new material was acceptable.

An analysis of the impact of the valve failure as analyzed in UFSAR was mad.e. As the material's properties are equivalent, there is no effect on the UFSAR analyses.

FACILITY IANGES THAT DID NOT REQUIRE.C APPROVAL MONTH/YEAR ) anuary I 988 N/A SCAFFOLD REQUEST 1/29/88 A temporary scaffold platform was constructed in

1. 1 EDG Room to work # 1 Diesel Room Dampers.

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

N/A SCAFFOLD REQUEST 1/20/88 A temporary scaffold platform was constructed in Auxiliary Building to work FT-VS-118 and FT-VS-218.

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

TM Sl-88-2 TEMPORARY MODIFICATION 1/29/88 Temporary modification removed and blanked the piping connection on the PG tank heat exchanger thermal relief valves, l-RV-BR-114A, B.

It was determined that maintaining the PG tank heat exchanger inlet and outlet isolation valves open prevents heat exchanger overpressurization while the thermal relief valves are removed. Therefore, the radioactive liquid release probability is not increased.

TM S2-88-2 TEMPORARY MODIFICATION 1/07 /88 This temporary procedure closed manual valve 2-SW-117 and placed it under administrative control to prevent over-cooling of lube oil for 2-CH-P-lB while the pump is off.

Closure of 2-SW-117 does not constitute an unreviewed safety question because it is under administrative control ensuring it will be opened if needed before operability of any plant equipment is affected.

FACIIJTY 'ANGES THAT DID NOT REQUIRE MONTH/YEAR January 1988 le APPROVAL TM S2-88-3 TEMPORARY MODIFICATION 1/11/88 This temporary modification closed manual valve 2-SW-168 (lube oil cooler SW isolation) under administrative control to prevent over cooling of lube oil for 2-CH-P-IA while the pump is shut down.

Closure of 2-SW-168 does not constitute an unreviewed safety question since it is under administrative control ensuring it will be opened, if required, before operability of any plant equipment is affected.

TM S2-88-5 TEMPORARY MODIFICATION l/26/88 This temporary modification placed the emergency borate valve, 2-CH-MOV-2350, under administrative control because the normal boric acid flow path from the blender was inoperable due to a heat tracing failure.

Placing 2-CH-MOV-2350 under administrative control will ensure two boric- acid flow paths are available to the charging pump suction as required.

TM S2-88-7 TEMPORARY MODIFICATION 1/26/88 This temporary modification locked closed 2-RC-133 to isolate containment penetration #57 and the pressurizer vent and vapor space sample.

The pressurizer vent system is used as a backup bleed path in case of a loss of heat sink transient. However, the preferred path remained available. The pressurizer vent system can also be used to vent non-condensible gases from the pressurizer vapor space. However, the PORV's remain available if this function is required.

PROC.URE OR METHOD OF OPERATIO-HANGES THAT DID NOT REQUIRE NRG APPROVAL MONTH/YEAR January 1988 2-TOP-2015 AUXIUARY FEEDWATER CHECK VALVE 1/05/88 LEAKAGE GUIDEIJNES UNIT 2 This temporary operating procedure isolated steam generator auxiliary feedwater flow paths on Unit 2 to determine potential check valve leakage paths.

Since the flow paths were under administrative control during the temporary operations and since automatic actuation will return the system to the required operating condition, it was determined that an unreviewed safety question was not created.

2-TOP-2015 AUXIIJARY FEEDWATER CHECK VALVE 1/26/88 LEAKAGE GUIDEIJNE UNIT 2 The temporary operating procedure was revised to extend the implementation date.

'.fhe administrative control and automatic actuations remain in place; therefore, the evaluation above remains valid.

SUADM-ADM-21 STATION PROCEDURES 1/26/88 This procedure revision updated the procedure deviation process to reflect the 10CFRS0.59 screening and review process.

The updated procedure incorporated more stringent requirements governing procedure deviations than outlined in the administration section of Technical Specification (section 6.4)
