SUBJECT:

CRACKING OF BRR JET PUMiP HOLDDONN BEAMS You recently received Inspection 5 Enforcement Bulletin 80-07, dated April 4, 1980, concerning the cracking of the jet pump holddown beams at Dresden 3.

Operating BWR's were requested to provide a written response to this bulletin.

BllR's not yet operating were issued this bulletin for information only.

Our Office of Inspection and Enforcement is currently monitoring the efforts of General Electric and various BklR Licensees to develop a long-term solution to the cracking problem.

Operating BhJR's are being required to take certain short-term actions such as inservice inspection to preclude excessive cracking awhile a 'long-term solution is developed.

It is expected that this long-term solution will be applicable to both operating and non-operating Bl~R's To aid us in our licensing review of the hlNP-2 facility, you are requested to provide the folio>ling information to us:

1.

Describe those actions being taken by you to preclude the occurrence of cracking similar to that described in IE Bulletin 80-07.

2.

Provide a commiitment to adopt whatever 'long-term solution is approved.

3. If you anticipate receiving an Operating License before a long-term solution is agreed upon, describe any short-term actions which you will take to prevent or detect excessive cracking.

Provide a rationale as to why these actions are sufficient to justify plant operation until a Iong-term solution is found.
