Subject:
Interim Report - DER 85-32 A 50.55(e) Potentially Reportable Deficiency Relating To Seismic Separation Between Buildings.
File: 85-006-216; D.4.33.2
Reference:
Telephone Conversation between A. Hon and T. Siegfried on September 17, 1985.
Dear Sir:
The NRC was notified of a potentially reportable deficiency in the ref-erenced telephone conversation. At that time, it was estimated that a determination of reportability would be made within thirty (30) days, (October 17, 1985).
Due to the extensive investigation and evaluation required, an Interim Report is attached.
It is now expected that this information will be finalized by November 1, 1985, at which time a complete report will be submitted.
Very truly yours, bd h44.

I.
Potential Problem 1
The original design intent at building interfaces was that a six inch seismic gap be maintained as indicated on Civil / Structural concrete and steel lay out design drawings to allow unrestricted relative building motions.
In Units 2 and 3 several hundred locations exist where the required s!x inch seismic separation has not been maintained j
between adjacent buildings and/or their attachments (Reference i
SCIP 667.0).
The majority of the structural components with less than the specified six inch separation have previously been identified on FCR's and NCR's.
Unit 1 is being evaluated
)
under EER 85-ZZ-058.
II.
Approach To and Status of Proposed Resolution Bechtel is currently studying this problem to determine reportability, root cause, and technical justification for corrective action.
III.
Projected Completion of Corrective Action 3
and Submittal of the Final Report The complete evaluation and final report are forecast to be completed by November 1, 1985.
