Dear Sir or Madam:

This letter is to advise NRC that CRANE Nuclear, Inc. (CNI) considers actions associated with the Part 21 Notification made to NRC in October of 1998 as complete. A copy of the original notification letter is attached for your use.

Our evaluation revealed that only four customers that issued a purchase order to Crane-Aloyco for the valve in question were affected. Notification letters to the following customers were sent via certified mail.

      GPU Nuclear, Inc. (see letter copy dated 10/9/98)
Westinghouse Electric Corporation (see letter copy dated 10/9/98)
Bechtel Power Corporation (see letter copy dated 10/23/98)
American Electric Power (see letter copy dated 10/28/98)

Included with this letter are copies of the notification letters issued by CNI to the affected customers and a copy of the U.S. Post Office Certified Letter Receipts returned from those same companies.

CNI has responded to a limited number of inquiries from individuals at the notified companies or from individuals that became aware of the notification on the NRC web page. CNI will continue to respond to any questions associated with the notification.

Attention: Document Control Desk
Subject: Discovery of a Defect as defined by 10CFR21

Dear Sir or Madam:

CRANE Nuclear Inc. has made a discovery of a condition or circumstance involving a basic component that could contribute to the exceeding of a safety limit.

During the manufacture of a replacement 10" figure N-2376 swing check valve, it was found that the weight of the replacement valve was significantly different from the value shown on the drawing for the original valve. The replacement valve weighs 490 lb., while the Aloyco drawing from 1970 shows the valve as 346 lb. The replacement valve did not ship to the intended customer because of this discrepancy.

Preliminary investigation suggests that the original weight value is not correct, and that the weight of the valve is close to that of the replacement. The weight of the valve from the drawing may have been used in the calculation of piping stresses or for other purposes by the utility. The discrepant weight is isolated to the 10" size of this figure number.

Crane Company acquired Aloyco in 1984. This is the first time a valve of this size and figure number has been manufactured by Crane Nuclear, Inc.

CRANE Nuclear Inc. is reviewing records to determine all customers that may be affected, and will send written notification to them in accordance with CNI procedure 15-100 and 10 CFR.Part 21.

If you have any questions concerning this matter, you may contact me by telephone at (630) 226-4940 or via E-mail at rosalie_hillis@cranevalve.com .

Sincerely,

CRANE Nuclear, Inc.
