REFERENCE:

Crane Letter Dated Afay 16,1994 Gentlemen:

llas letter is afollow-up to the referenced letter, in which Crane Valves Nuclear Operations advised that we were undertaking an investigation to determine of data supplied in the mid-1980's was used by Nuclear Utilities to set torque switches in Afotor Operated Valves.

As described in the Afay correspondence, over 600 issues of Engineering calculations have been generated and the scope of that evaluation is even greater than we initially anticipateil As of this date, we have uncovered no contractual evidence to support thefact that Crane supplied erroneous data to Utilities, since most orders do not specify the objective of our earlier evaluations.

Continuedprogress reports will be provided on this project andyou can direct any questions to my attention at 815 740-7597.

SUBJECT:

INTERInf REPORT OF 10 CFR PART 21 EVALUA TION

REFERENCE:

WEAK LINK ANALYSIS FOR of0 TOR OPERA TED VAL VES (hf0V's)

Gentlemen:

In accordance with 10 CFR Part 21, Article 21.21 (a) (2), Crane Valves Nuclear Operations (formerly Crane-Aloyco) hereby advises that we are undertaking an evaluation to determine of data supplied in the mid-1980's as Crane-Aloyco "0TC" Reports has been used by Nuclear Utiliths to set torque switches in Af0V's.

At issue is not the analytical methods, but the use of data beyond the intended scope. This .

issue surfaced as a result of review of revised OTC reports supplied to Florida Power Corp.

for h10V's at Crystal River Unit #3.

To date, Crane has generated over 600 OTC reports. Accordingly, the scope of the evaluation will extend beyond the 60 day reporting period of10 CFR Part 21. As part of '

our investigation, we are considering the applicability of reporting requirements in light of '

GL 89-10 and the possibility that this circumstance has already been addressed by other NRC Communications such as IN 92-41 or IN 94-18.

f Crane Valves Nuclear Operations' representatives have meet with technical and licensing representativesfrom Florida Power Corp. on two separate occasions to discuss these issues and to assure that substantial safety hazards are avoided.

We anticipate completion of this evaluation by July 29,1994, at which time the reporting requirements of10 CFR Part 21 Paragraph 21.21 will be satisfied.
