Dear Mr. Rhode:

g./PD&

~ebb You recently received Inspection

& Enforcement Bulletin 80-07. dated April 4,

'l980, 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.

BWR's not yet operating were issued this bulletin-f'r information only.

Our Office of Inspection and Enforcement is currently monitoring the efforts of G'eneral Electric and various BWR Licensees for developing a long-term solu-tion to the cracking problem.

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

It is expected that this long-term solution will be applicable to both operating and non-operating BWR's.

To afd us in our licensing review of Nine flfle Point No. 2, you are requested to provide the following information to us:

1.

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

2.

Provide a commitment to adopt whatever long-term solution fs 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 long term solution fs found.
