Crane Letter Dated May 16,1994 Gentlemen:

This letter is afollonuup to the referenced letter, in which Crane Valves Nuclear Operations advised that we were undertaking an investigation to determine if data supplied in the mid-l980's was used by Nuclear Utilities to set torque switches in biotor Operated Valves.

As described in the Afay correspondence, over 600 issues of Engineering calculations have  :

heen generated and the scope of that evaluation is even greater than we initially anticipatest 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 specsfy the objective of our earlier evaluations, it is expected that *he evaluation will be completed within the next 60 days. Any questions can he directed to my attention et 815-740-7571. l Sincerely,

SUBJECT:

INTERIM REPORT OF 10 CFR PART 21 EVALUA TION

REFERENCE:

WEAK LINK ANALYSIS FOR MOTOR OPERATED VALVES (MOV's)

Gentlemen:

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

At issue is not the analytical methods, but the use of data beyonl1 the intended scope. This issue surfaced as a result of review of revised OTC reports supplied to Florida Power Corp.

for MOV'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.

Crane Valves Nuclear Operations' representatives have meet with technical and licensing l representativesfrom I oride, Power Corp. on two separate occasions to discuss these issues and to assure that substanthi safety hazards are avoided. i 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.
