Subject:

Braidwood Station Units 1 and 2 Response to IE Inspection Report Nos. 50-456/78-06 and 50-457/78-06 NRC Docket Nos. 50-456 and 50-457 Reference (a) : September 7, 1978 letter from Cordell Reed to James G. Keppler

Dear Mr. Keppler:

Per Reference (a), Commonwealth Edison Company requested that the NRC place an item of noncompliance in abeyance until Commonwealth Edison Company received a response on a code inquiry to the American Society of Mechanical Engineers (ASME) Committee. Your September 25, 1978 letter concurrad.

Enclosed for your review as Attachment 1 is the ASME response to Commonwealth Edison's inquiry regarding your apparent noncompliance on the radiographic procedure used on material outside the thickness range permitted in Paragraph T-243 of Article 2,Section V, 1974 Edition of the ASME Code.

Also enclosed for your ipZormation, as Attachments 2 and 3, are copies of the ASME Committee's acknowledgment of Commonwealth Edison's inquiry and Commonwealth Edison's inquiry of the subject matter.

Since the ASME response supports Commonwealth Edison's contention that an additional "special" procedure was not intended by the code when an existing procedure produces radiographs of acceptable sensitivity, commonwealth Edison requests that the NRC reexamine this apparent item of non-compliance and consider changing this infraction to an observation.

This same paragraph in the 1977 Edition of Section V says "when it is not practical to perform radiography within the limitations outlined in M41 or T-242 or whe n radioactive isotopes other than ,
