Docket No:
50-358 Mr. Earl A. Borgnann Vice President - Engineering i
Cincinnati Gas & Electric Company P. O. Box 960 Cincinnati, Ohio 45201
Dear Mr. Borgmann:
SUBJECT:
CRACKING OF BWR JET PUMP HOLDDOWN BEAMS The Office of Inspection and Enforcement recently issued Bulletin 80-07 l
concerning the observed cracking of the jet pump holddown beams at Dresden 3.
This bulletin required a written response from all operating BWR's but not from BWR's under construction.
We have decided that this subject should be considered an open issue in our operating license review of BWR's such as Zinner and LaSalle. We understand that I&E and GE are developing a long term ger.eric fix for this problem. However, we believe that the BVR's under construction should document their actions being taken with respect to this problem and demon-strate that a level of safety sufficient for licensing has been achieved.
Therefore, we would appreciate your response to the enclosed request.
Sincerely, WAV g
A. S'chwencer, Chief Licensing Branch No. 2 Division of Licensing

.i All BWR's Not Yet Licensed To Operate:
You recently received Inspection & Enforcement Bulletin 80-07, dated April 4,1980, concerning the cracking of the jet pump holddown beams at Oresden 3.
Operating BWR's were requested to provide a v ritten response to this bulletin. BWR's not yet operating were issued this bulletin for information only.
Our Office of Inspection and Enforcement is currently monitoring the efforts of Ger.eral Electric and various BWR Licensees for developing a long-term solution 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 aid us in our licensing reviews of BWR's, you are requested to provide the following information to us.
1.
Describe those actions being taken by you to preclude the occurrance of cracking such as described in IE Bulletin 80-07.
2.
Provide a commitment to adopt whatever long-term solution is approved.
3.
For BWR's which 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 is found.
