UNITED STATES t NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT N0.85 TO FACILITY OPERATING LICENSE NO. NPF-21 WASHINGTON PUBLIC POWER SUPPLY SYSTEM NUCLEAR PROJECT NO.
2 DOCKET NO. 50-397
- 1. 0 INTRODUCTION By letter dated February 5, 1990, the licensee for Washington Public Power Supply System Nucl'ear Plant 2 (WNP-2) proposed changes to the surveillance test frequency and the failure reporting requirements for the emergency diesel generators contained in Table 4.8.1.1.2-1 and Section 4.8.1.1.3, respectively, of the plant's Technical Specifications.
These requested changes provide for an increase in the number of valid test failures before an increase in test frequency is required as recommended in Generic Letter (G.L.) 84-15.
The proposed changes and our evaluation of these changes are as follows.
- 2. 0 EVALUATION The licensee proposed the following changes to Table 4.8.1.1.2-1 which we find acceptable on the basis that they are consistent with the example technical specifications contained in G. L. 84-15:
~Chan e 1: In the first sentence of Footnote *, delete "last 1DD tests are determined on a per nuclear unit basis" and substitute "number of tests and failures is determined on a per diesel generator basis."
~Chan e 2: Delete all the existing entrees from the table and substitute:
Number of Failures in Last 20 Valid Tests*
Number of Failures in Last 100 Valid Tests*
Test Fre uenc Greater than or equal to 2**
Greater than or equal to 5
Less than or equal to 1 Less than or equal to 4 At least once per 31 days At least once per 7 days
~Chan e 3:
Add the following as a
new footnote: "** Once this test frequency is required, it shall be maintained until seven consecutive failure free valid tests have been performed and the number of failures in the last 20 demands has been reduced to one."
9006070082 900S3l PDR ADOCK 0 000397 PDC 3.0 The licensee proposed the following change to Section 4.8.1.1.3 which we find acceptable on the basis that it fol]ows the intent of G.L. 84-15.
~Chan e 4: In the third sentence delete "per nuclear unit basis" and substitute "per diesel generator basis."
ENVIRONMENTAL CONSIDERATION This amendment involves a change in requirements with respect to the surveillance of facility components located within the restricted area as defined in 10 CFR Part 20.
The staff has determined that this amendment involves no significant increase in the amounts, 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 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 connec-tion with the issuance of this amendment.
4.0 CONTACT WITH STATE OFFICIAL 5.0 The Commission made a proposed determination that the amendment involves no significant hazards consideration (55 FR 10548, March 21, 1990) and consulted with the State of Washington.
No public comments were received, and the State of Washington did not have any comment.
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 will be conducted in compliance with the Commission s regula-tions and (3) the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
