Dear Dr. Grace:

ADEQUACY OF THE CLINCH RIVER BREEDER REACTOR PLANT (CRBRP) REACTOR VESSEL NON-DESTRUCTIVE EXAMINATION (NDE) PROCEDURE

Reference:

Letter HQ:S:83:226, J. R. Longececker to J. N. Grace,

" Additional Inforcnation on the CRERP Non-destructive Examination (NDE) Procedu.e," dated February 28, 1983 Enclosed is a report entitled "The Adequacy of tne CI'BR? Reactor Vessel NDE Inspections" that was promised in the reference letter. Thls report supports the conclusion by the applicants that NDE performed or, the reactor vessel is adequate. Further NDE (e.g. ultrasonic examination) is not likely to make a significant contribution towards finding additional flaws other than those previously identified during the fabrication NDE. This conclusion is also believed applicable to the ex-vessel storage tank and other vessels of the primary and intermediate heat transport systems and the direct heat removal service.

Questions regarding the enclosed report should be addressed to Mr. R. Spear (FTS 626-6154) of the Project Office Oak Ridge staff.

Sincerely,

. C+
