WASHINGTON, D.C. 20555 4 01 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 73 TO FACIllTY OPERATING LICENSE NO. NPF-62 ILLIN0IS POWER COMPANY. ET AL.
CLINTON POWER STATION. UNIT NO. 1 DOCKET NO. 50-461
1.0 INTRODUCTION
By letter dated October 16, 1992, the Illinois Power Company (IP, the licensee) requested an amendment to Facility Operating License No. NPF-62 for the Clinton Power Station (CPS).
The proposed amendment would make editorial changes to the Clinton Power Station Facility Operating License and Technical Specifications (TS) to correct typographical errors, provide clarification and remove provisions which are no longer applicable.
2.0 EVALUATION The licensee is proposing the following changes to the CPS Facility Operating License and TS:
t 1.
Delete item (b) from paragraph D of the CPS Facility Operating License and reletter the remaining items, as appropriate.
Item (b) provided exemptions from the requirements of General Design Criteria (GDC) 61 to permit the deferral of a portion of the Fuel Handling System preoperational testing until prior to off-loading fuel from the reactor vessel.
Since the testing has been completed and the system declared operable, the staff finds the deletion of this license condition acceptable.
i 2.
Revise TS 3.5.2, "ECCS - SHUTDOWN," item e.2 and TS 3.5.3, " SUPPRESSION POOL," item b.3, to delete the condition " equivalent to a level of 95%."
TS 3.5.2.e.2 and 3.5.3.b.3 identify the minimum required available volume in the Reactor Core Isolation Cooling (RCIC) system storage tank in the event the suppression pool level is less than the applicable limit during operational conditions 4 and 5.
The TS currently identify a volume of "at least 125,000 available gallons of water, equivalent to a level of 95%."
The available i
level instrumentation provides a tank level range of 0-30 feet and does not i
provide level indication in terms of percentage.
The phrase " equivalent to a level of 95%" is not defined in terms of total tank volume or usable water volume and is not meaningful to the control room operators. The licensee contends that the requirement to maintain 125,000 available gallons of water is sufficient to determine system operability and, therefore, proposes to 9305140166 930504 PDR ADOCK 0500 1
j P
, delete the phrase in question.
The staff concurs with the licensee and finds the proposed modification acceptable.
3.
Revise TS 3.8.3.2, " DISTRIBUTION - SHUTDOWN," item a.3.d to delete the
"*" attached to this item.
TS Limiting Condition For Operation (LCO) 3.8.3.2.a.3 identifies the Division III AC power distribution system equipment required to be operable during shutdown conditions.
Footnote "*", which states "When handling irradiated fuel in the secondary containment," was intended to define the "*" which appears in the LCO Applicability statement. While TS 3.8.3.2.a.3.d is applicable during the operational condition defined by "*", it was not intended that the "*" be attached to item a.3.d.
Since this change will not impact which equipment is required to be operable, and will eliminate the confusion generated by the "*" being inappropriately attached to the LCO, the staff finds this change acceptable.
4.
Rgise TS 3/4.9.12, " INCLINED FUEL TRANSFER SYSTEM," to delete footnote Delayed preoperational testing of the Fuel Handling System resulted in the addition of footnote "**" to TS 3/4.9.12 to permit an exception to the operability requirements for the blocking valve in the fuel building Inclined Fuel Transfer System hydraulic power unit and the liquid level indicator prior to off-loading irradiated fuel from the reactor vessel.
Since the testing has been completed and the system was declared operable, the staff finds the deletion of the footnote from the referenced TS acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Illinois State official was notified of the proposed issuance of the amendment. The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATI_0J This amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes surveillance requirements. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released off-site, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consider-ation and there has been no public coment on such finding (58 FR 16862).
Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 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 the amendment.

5.0 CONCLUSION
i lhe staff has 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, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
