REQUEST FOR AMENDMENT 3 FACILITY OPERATING LICENSE DPR-70 NO. 1 UNIT SALEM NUCLEAR GENERATING STATION DOCKET NO. 50-272 In accordance with the Atomic Energy Act of 1954, as amended, and the regulations thereunder, PSE&G hereby requests that Facility Operating License DPR-70 for Salem Nuclear Generating Station, Unit No. 1, be amended as set forth below:

APPENDIX A,. TECHNICAL SPECIFICATIONS

1. Auxiliary Building Exhaust Air Filtration System, specification 3.7.7.1

a. Limiting Condition .for Operation:

This specification should be changed to read as follows:

"At least one Auxiliary Building exhaust air HEPA filter train, associated with the one charcoal adsorber bank, and at least two exhaust fans shall be OPERABLE. "

b. ACTION:

Action statement "a." should be changed to read as follows:

"With the above required HEPA filter train iriopera-ble, restore the HEPA filter train to OPERABLE

.. v status within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months ."

The above changes are required to bring the specifi-cation in conformance with the design basis of the Auxiliary Building Exhaust Air Filtration System i.e.r only one HEPA filter train is required to be opera- _

tional in conjunction with the one charcoal adsorber bank, in order to ensure that radioactive materials leaking from ECCS equipment following a LOCA are filtered prior to reaching the environment. The ACTION statement ensures that the reactor will be shut down in the event that the required HEPA filter train becomes inoperable. A second HEPA filter train is available for use in conjunction with the charcoal adsorber bank. It is expected that this HEPA filter train will be modified to meet the technical specifi-cation requirements such that it can be used inter-

changeably with the first for operating flexibility.

The above changes do not compromise the level of safety that has been designed into the system. A flow diagram is attached.

c. SURVEILLANCE REQUIREMENTS:

Specification 4.7.7.1 should be changed to read as follows:

.. "The above required Auxiliary Building exhaust air filtration system shall be demonstrated OPERABLE:

a. At least once per 31 days by initiating, from the control room, flow through the HEPA filter and charcoal adsorber train and verify-ing that the filter train and each fan operates for at least 15 minutes."

The above changes are necessary to bring these surveillance re-qul.rements in conformance with the requested changes to the LIMIT-ING CONDITIONS FOR OPERATION and the ACTION statement.

d. BASES:

3/4.;7.7.AUXILIARY BUILDING EXHAUST AIR FILTRATION SYSTEM (page B 3/ 4 7-5) : .

Add the following statement:

"ANSI N510-197S*should be used as a procedural guideline for surveillance testing."

The design of the system was completed in 1972, prior to publica-tion of ANSI NSlO in 1975, and does not provide for compliance with several requirements of the ANSI Standard. For example, filter bank velocity distribution at the center of each filter

cannot be measured upstream of each filter face, as required by the Standard, because the physital arrangement of the system does not provide for thi,,i:>. We have performed extensive testing on the system and have determined that we cannot test in accordance with ANSI N510:-1975 ."

System cannot be tested "in accordance with ANSI NSl0-1975" with-out excessive hardship or great expense, thereby making the above changes necessary.

The inclu9ion of the proposed statement in the BASES will ensure that the intent of ANSI N510-1975 is being considered in sur-veillance testing, thereby maintaining the intended quality of surveillance required in the Technical Specifications.

REFUELING OPERATIONS BASES

3/4.9.10 and. 3/4.9.11 . WATER LEVEL - REACTOR VESSEL AND STORAGE POOL The restrictions on minimum water level ensure that sufficient water depth is available to remove 99% of the assumed 10% iodine gap activity released from the rupture of an irradiated fuel assembly. The minimum water depth is consistent with the assumptions of t.he accident analysis.

3/4.9.12 FUEL HANDLING AREA VENTILATION SYSTEM The limitations on the fuel handling area ventilation system ensure

that all radioactive material released from an irradiated fuel assembly will be filtered through the HEPA filters and charcoal adsorber prior to discharge to the atmosphere. The OPERABILITY of this system and the resulting iodine removal capacity are. consistent with the assumptions of the accident analyses. ftAJ.5.I )Js-jo ~/'7 ?.r" ~~ 4e ~a.,.,
