REQUEST FOR ADDITIONAL INFORMATION FOR TECHNICAL SPECIFlCATION (TS) CHANGE - ELECTRICAL POWER SYSTEMS PALISADES NUCLEAR PLANT DOCKET NO. 50-255 1.0 The Bases associated with the TS Surveillance Requirement Section 4.7.3.1 indicate that the fuel oil storage tank (T-10) is also used as fuel oil for the diesel fire pumps, heating boilers and waste evaporators, and as lube oil for the emergency diesel generators (EDGs).

Provide the following information:

a.

the provision in the emergency operating procedures for isolating these components/systems following a loss-of-coolant accident (LOCA},

or

b.

detailed calculations to demonstrate that the fuel oil stored in T-10 and the day tank will be sufficient to support the operation of these components and EOG for 7 days following a LOCA.

Information to be provided should include:

Fuel oil consumption rate for each of the above cited components.

Methodology/assumptions used to calculate the fuel oil consumption rates.

Since the calculated EOG fuel oil consumption rate is based on the time dependence of EOG loads, has a minimum margin of 10% been added to the calculated storage requirement?

2.0 Section 8.4.1.3 of the FSAR states that the plant modification reported in Facility Change FC-889 provides the capability to transfer fuel oil from the fuel oil storage tank (T-926) to T-10 and enables a backup fuel supply to T-ld from another onsite source.

Provide the following information:

a.

Discuss the procedure established to transfer fuel oil from T-926 to T-10 following a LOCA.

b.

Discuss the equipment (portable or permanent) to be used for fuel oil transfer from T~926 to T-10.

If portable equipment is utilized for the fuel oil transfer, discuss the provision for maintaining the readiness of this portable equipment.

c.

Discuss the administrative control and amount of fuel oil reserved in T-926 for the operation of EOG following a LOCA.

3.0 The response to the staff's comment (Q-4) states that the proposed 24-hour allowed outage time (AOT) for P-18A was not based on the.DG run time (15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />) due to the available fuel oil stored in the day tank.

It was based on a judgement of the relative severity of both DGs being inoperable or both offsite sources being inoperable and was intended to allow a reasonable time for repair of P-18A prior to declaring DG-12 to be inoperable.

Discuss in detail how the relative severity of both DGs being inoperable or both offsite sources being inoperable is determined.

ENCLOSURE

' Discussion should include the assumptions and the justifications for the assumptions used to make this determination.

(We find that the fuel oil stored in day tank is only sufficient to support DG-12 operation for 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />, therefore, the AOT for P-18A should be less than 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />.)

4.0 To be consistent with the guidance described in NUREG-1432, "Standard Technical Specifications, Combustion Engineering Plants," the following should be included in the TS Action Sections:

- The minimum inventory of fuel oil required to be maintained in the DG day tank.

The minimum air pressure required to be maintained in the DG starting tank.*
