l SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 46 -TO FACILITY OPERATING LICENSE NO. NPF-43 DETROIT EDISON COMPANY WOLVERINE POWER SUPPLY COOPERATIVE. INCORPORATED f

FERMI-2 DOCKET NO. 50-341

1. 0 INTRODUCTION By letter dated November 15, 1988, the Detroit Edison Company (DECO or the' licensee) requested amendment to the Technical Specifications (TS) appended

to Facility Operating License No.-NPF-43 for Fermi-2.

The proposed amendment would delete references in the TS to Special Test Exception-0xygen Concentration 3/4.10.5, because the period for which'this exception was valid has passed.. The exception expired on May 23, 1988, after 120 Effective Full Power Days of Operation.

2.0 EVALUATION i

Special Test Exception-Oxygen Concentration TS 3.10.5.has been a part of the Fermi-2 TS'since original licensing to allow relief from the oxygen concen-tration specifications in order to provide access'to the primary containment-during the-initial startup and testing phase of operation. ' Since-the period for which this exception was valid has passed,-the licensee has-proposed a change to the TS to-remove all reference to the' exception.

Specifically, the proposed revision would delete a footnote to the requirement for Drywell Oxygen Concentration in< Table 3.3.7.5-1,: Accident Monitoring Instrumentation, which references Specification 3.10.5, Special Test Exceptions-0xygen Concentration.

- o

- This test exception was applicable-with reactor operational exposure up to 120 Effective Full Power Days (EFPD). ' Fermi-2 has operated greater than this limit,.

and thus the exception is no longer valid.

The special test exception is also footnoted in Specification 3.4.6.6.2,' Orywell and Suppression Chamber Oxygen Concentration.

Deletion of Specification 3.10.5 and corresponding references to 3.10.5 are included in this proposed change. Deletion of the corresponding Bases for the Special Test Exception is also proposed.

The special test exception is no longer applicable since 120 EFPD has been exceeded.

2.2 3/4.10.5, Oxygen Concentration Current:

The provisions of Specification 3.6.6.2 and the OPERABILITY requirements of the Drywell Oxygen Concentration instrument of Specification 3.3.7.5 may be suspended during the performance of the Startup Test Program until either the required 100% of RATED THERMAL POWER trip tests have been completed or the reactor has operated for 120 Effective Full Power Days.

Proposed: The exception is no longer valid due to the plant exceeding 120 EFPD, this entire specification is proposed to be deleted.

2.3. 3.6.6.2, APPLICABILITY Current:

OPERATIONAL CONDITION 1*, during....

• See Special Test Exception 3.10.5 Proposed: OPERATIONAL CONDITION 1, during....

The footnote *, in the proposed amendment is being deleted since the APPLICABILITY requirements to apply the exception (less than 120 EFPD) has been exceeded.

2.4 Conclusion Since, the special test exception for oxygen concentration expired after 120 EFPD, on May 23, 1988, the TS require a change to reflect the expiration of the exception.

The proposed amendment removes all references to the exception for oxygen concentration.

The staff has reviewed the proposed amendment and finds the elimination of the sections in the TS, including the Bases, which are referenced to the special exception to be acceptable.

3.0 ENVIRONMENTAL CONSIDERATION

This amendment involves change in a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes to the surveillance requirements.

The staff has

. determined that this amendment involves no.significant increase in the amounts, and no significant change in the types, of any effluents which may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission 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 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 this amendment.

4.0. 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 L

endangered by operation in the proposed manner, and (2).such activities will be conducted in compliance with the Commission'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, i
