December 28, 1978 Docket No. 50-155 Mr. David Bixel Nuclear Licensing Administrato Consumers Power Company 212 West Mi:higan Avenue Jackson, Michiga: 49201
Dear Mr. Bixel:
RE: PIPE BREAKS INSIDE CONTAINMENT FOR THE BIG ROCK P0 INT FACILITY General Design Criterion 4 of Appe_ndix A to Title 10, Code of Federal Regulations, Part 50, requires in p' art that:
... structures, systems and components shall be designed to accomodate the effects of loss-of-coolant accidents and shall be appropriately protected against dynamic effects... ".
Acceptable methods of complying with this regulation are, in part, provided in the Standard Review Plan Section 3.6.2 and Regulatory Guide 1.46 (Protection Against Pipe Whip Inside Containment).
As you are aware, the Systematic Evaluation Program includes a topic on the Effects of Pipe Break on Structures, Systems and Components Inside Cor.cainment (III 5.A) which stems from this basic regulation and current licensing criteria.
Our review of material currently in your docket has not revealed sufficient infomation for technical evaluation of the subject.
As we have previously stated, it would be necessary for the licensees to provide some evaluation for our review of certain SEP topics.
We have determined that your assistance is needed to supply technical information which will allow us to compare your plant design to current criteria and to evaluate the significance of potential deviations. Enclosed is a copy of a letter you received earlier;.
which summarized current criteria and discusses the SEP review approach presently planned.
A meeting will be scheduled to oiscuss this topic with,/ou.
As soon as possible, but at least two weeks prior to that meeting, you should provide any pertinent infomation you may have, by reference to docketed material or copies of additional relevent studies or analyses which may not have been docketed. At this meeting, yr.u should be prepared to discuss a program for resolving this topic.
Based upon the lack of docketed information, we expect this program may require substantial effort on your part.

Mr. David Bixel Decenber 28, 1978 If you have any questions prior to the meeting, please call the assigned Project Manager.
Sincerely, C/
