g UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20566 February 14, 1990 Docket No. 50-298 Mr. George A. Trevers, Division Manager - Nuclear Support Nebraska Public Power District Post Office Box 499 Columbus, Nebraska 68601-0499 l

SUBJECT:

REVIEW OF NEBRASKA PUBLIC POWER DISTRICT'S RESPONSE TO GENERICLETTER88-01(TAC.NO.69131)

)

The staff, with the assistance of its contractor, Viking $ystems International, has completed its review of Nebraska Public Power District's (NPPD) responses to Generic Letter 88-01 dated August 3 December 19, and July 24, 1989. We find that your responses to the requirements are acceptable, with the exception of the following:

1.

Your responses concerning intergranular stress corrosion cracking (IGSCC) classifications and accessibility contain conflicting snd inconsistent information.

The staff will find these responses acceptable, provided that the< recourendations described in Section 2.3.5 of the enclosed TechnicalEvaluationReport(TER)areimplemented.-

2.

.Your responses declined to propose a Technical Specification change that includes a statement on inservice inspection (ISI) as required by this generic letter. This position is not acceptable. NPPD should propose an amendment to the Cooper Technical Specifications as i

required by Generic Letter 88-01. The model specification for boiling water reactors that was provided in Attachment B to the generic letter should be utilized unless -changes are necessary to accommodate plant specific differences at Cooper Nuclear Station.

3.

NPPD has also declined to propose an amendment to the Technical Specifications that limits the increase in unidentified leakage to 2_gpm over a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or less, as required by Generic Letter 88-01.

Your position is unacceptable. NPPD should propose the required Technical Specification.

4.-

HPPD's position on reporting of flaws and flaw evaluation is not in i

conformance with the NRC staff position stated in Generic Letter 88-01.

NPPD should modify its position on reporting requirements and repair criteria to conform to the NRC staff position as required in Generic Letter 88-01.
