INSPECTION REl>0RT 50-498/85-26, 50-499/85-23
Dear-Mr. Goldberg:
This letter conveys the results and conclusions of NRC's evaluation of the
following Stone and Webster Engineering Corporation (SWEC) EAP Independent
Technical Assessment Tasks:
83-1, Soil-Structure Interaction and Seismic
Design Verification; 83-3, ASME III Pipe Stress Analysis of RHR/SI System;
84-1, Containment Analysis; 84-2, Environmental Qualification of Equipment;
and 84-3, ASME III Pipe Support Design. The inspection was conducted by a
team of personnel from the NRC's Office of Inspection and Enforcement and
consultants at the offices of Bechtel Energy Corporation (BEC), Houston,
Texas from December 2, 1985, through December 6, 1985. The objective of
this inspection was threefold:
(1) verify that the concerns developed by
the SWEC audit team had been correctly implemented as action items; (2)
determine if~the action items had been satisfactorily resolved;.and (3)
verify that the appropriate corrective actions had been implemented or, if
the corrective, actions were part of an ongoing resolution program, verify
that proper implementttion was in progress.
In addition, at the request of
Houston Lighting and Power (HL&P), four work packages in the civil / structural
area were reviewed to determine if the results of these reviews, performed by
BEC to validate the original engineering design work performed by Brown and
Root, could be used to supplement the scope of review in the civil / structural
l
area of the EAP.
Based upon our inspection, it was concluded that Tasks 83-1, 83-3, 84-1,
84-2 and 84-3 had been acceptably completed subject to the resolution of the
NRC's comments, as described in the enclosed report. The HL&P review was
comprehensive, checklists were thoroughly completed, files were in good
order, backup documentation was in good order and corrective actions were
' implemented in an auditable manner.

Mr. J. H. Goldberg
-2-
The NRC found that the work package reviews performed by BEC were thoroughly
and comprehensively performed. However, since Bechtel did not adopt all of-
Brown and Root's design methodology but instead used some alternate approaches,
it was agreed that additional supplements to the EAP in the civil / structural
area are appropriate. This work will be reviewed by the NRC, when completed.
Sincerely,
