ORDER REQUESTING LICENSEE TO SUPPLY INFORMATION BY AFFIDAVIT (June 2, 1980)

The Board is concerned about some of the implications of the Licensee's report to the NRC Region V Office of Inspection and Enforce-ment, dated May 19, 1980, regarding discovery of an Auxiliary Building wall which is not adequately connected at its top to interfacing structural elements.

Although the Licensee claims that this particu-lar wall participates only as a minor structural element in the STARDYNE finite element analysis of the Building Complex, that does not relieve our concerns about other walls that might '.tave a similar defect and contribute a larger individual or cumulative effect of much greater significance.

Accordingly, the Board requests the Licensee to supply by affidavit the following information:

(a)

The cause of the occurrence, (b)

When all other walls with similar potential defects will have been examined to determine if there are other such problems, YtY, i 7

, (c)

Report of method and timeliness of corrections'to the current identified defects and any others discovered, and (d)

Contribution to structural adequacy of 'he Building Complex for any other walls found with this deficiency.

It is so ordered.
