20555 Gentlemen:

REQUEST FOR ENFORCEMENT DISCRETION TECHNICAL SPECIFICATIONS SURVEILLANCE REQUIREMENT 4.8.2.3.2 (b) (1)

FACILITY OPERATING LICENSE DPR-70 SALEM GENERATING STATION UNIT 1 DOCKET NO. 50-272 Public Service Electric and Gas Company (PSE&G) requests Enforcement Discretion from the provisions of Technical Specification surveillance requirement 4.8.2.3.2 (b) (1),

for individual cell (no. 47) voltage on the lC 125 volt battery for a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period beginning 9:04 AM on August 24,1993.

As discussed in Attachment A to this letter, PSE&G has concluded that granting this request will not be a potential detriment to public health and safety, or involve adverse environmental consequences.

Additionally, this request does not involve a significant safety hazard.

Salem Technical Specifications state that at least once per 92 days, the voltage of each connected cell must be verified greater than or equal to 2.13 volts under a float charge.

We are requesting Enforcement Discretion because one cell of a sixty cell 125 volt battery has a voltage below the surveillance specified value of 2.13 volts.

A new replacement cell has been ordered and is expected to be installed today (8/24/93).

Jumpering out the degraded cell could resolve the issue, however, this action requires disconnecting the entire battery from the bus/battery charger while completing the single cell jumpering.

During this period when the battery charger is supplying the DC bus without the normal battery load, a loss of battery charger or*

excessive output fluctuations (charger is not designed to operate independent of the battery) could result in a plant trip.
