JAMES A. FITZPATRICK NUCLEAR POWER PLANT DOCKET NO.60-333 i
INTRODUCTION By letter dated March 13, 1990, the Power Authority of the Sate of New York i
(PASNY Jr the licensee) submitted an amendment for chances to the Technical Specifications (TS) for the James A. FitzPatrick Nuclear Power Piant. The change would revise Surveillance Requirement 4.9.T.6 to correctly identify the location of the circuit breakers used to perform the monthly operdmty test.
.of the Independent Power Supply (IPS) associated witn each Low Pressure Coolant Injection'(LPCI) system. The present TS indicate that the circuit bre d es are located on the output of the IPS batter located at the alternating current (AC)y chargers. However, they are actually input to the IPS battery chargers. In addition, a change to Specification
- 9.F.2.a would replace a colon with a semicolon at the end of the specification.
EVALUATION Each of the Wo IPSs consit,ts of a battery to suppl which is capa~olc of converting the direct current (y power to an inverterDC) from the battery
'e when the Residual Heat Removal system is used in the LPCI mode. Normally the battery is maintained in a charged condition by a rectifier / charger whose input breaker is powered from an emergency AC bus and opens when a condition which requires automatic startup of the LPCI system is detected.
The AC output from the respective IPS provides power, independent.of other station power supply systems, which can be used to operate the three LPCI injection motor operated valves (MOVs) in each LPCI loop OO-MOVEA.
10-MOV27A.10-MOV66A.10-MOV25B 10-M0Y27B,10-M0V66B) and the recirculttion
. loop (02-MOV43A. 02MOV53A 02-MOV43B and 02-MOV53B).
In the event of,a loss of i
coolant accident.(LOCA), the IPS rectifier / charger input breaker is automatically opened to isolate the IPS from the emergency AC power system prior to automatic ooeration of the valves.
TS Surveillance Section 4.9.F.6 requires that a monthly test of each IPS be performed to verify proper operation of the battery and inverter. The test is i
performed by opening the same AC input breaker to the rectifier / charger which would open automatically should a LPCI automatic startup condition be detected and'then verifying that proper IPS output voltage and frequency are maintained.
The present TS section incorrectly identifies this breaker as the battery chreger output breaker.

SUMMARY
The proposed change to Specification 4.9.F.6 consists of a minor correction to an error which cxists in the identification of the proper breaker that is used to perfom the surveillance test that is designed to ensure operability of the IPSs. The propcsed change is consistent with the system description and operation contained in the Final Safety Analysis Report and in system drawings and procedures.
The change does not alter the methodology or frequency of the surveillance test as detailed in the present procedures, nor does it affect plant operation.
The change is, therefore, acceptable.
i
~
The change to Specification 4.9.F.2.a to replace a colon with a semicolon at.
the end of the statement corrects r. grammatical error.
This change had no i
effect on the Federal Reaf ster notice and is acceptable.
ENVIRONMENTAL CONSIDERATION This amendment involves a change to a surveillance requirement. The sta*/f has
[
detemined that the amendment involves no significant increase in the ecunts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Comission has previously issued a proposed finding that this amendment involves no significant hazards consideration and there has.been no public comment on such finding. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in i
10 CFR Sec 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact ~
statement or environmental assessment need be prepared in connection with the issuance of this armdment.
-i CONCLUSION We have concluded, based on the considerations discussed above, that:
(1)there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities wili
+
be conducted in compliance with the Comission's regulations and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
