5), 6), and 7) were interim reports on the subject condition.
l Based on the current WNP-1 slowdown, it is still not possible to provide i a final completion date for the subject design analysis. Progress
! reports have changed very little based on the reduced level of effort being expended to complete the analysis verification and redesign. As a result the Supply System will provide the next interim report when the analysis verification is completed or not later than construction restart.

-COMPLETED:
MSS 75- -LAD reanalysis for these lines has been-completed and the pipe stresses and'sup-port loads for ' this load-case must be combined with other- load-cases and the
.results evaluated.
FWS 75 ' LAD reanalysis for these lines has been
& completed and the pipe stresses and sup--
FWA port loads for this load-case must be combined- with other load-cases and the results evaluated.
DHR- 100 Pipe stresses have increased; however, Drop Line they are within acceptable limits. Due to increased loads resulting from the dynamic reanalysis, four supports out of nine were found to be unacceptable and must be modified. Nozzle (B&W) loads have exceeded the limits.
CFS & 75 LAD reanalysis for these lines has been DHR (LiI) completed and the pipe stresses and sup-port loads for this load-case have been combined with other load-cases and the stresses have been found acceptable.
Supports are being checked for accep-tance. Nozzle (CF Tank Outlet) loads have been exceeded slight?y. B&W's acceptance is required.
MUS (HPI) 0 Time history data is required from 8&W.
Reanalysis has not started.
Instrument 20 Time history data has been received from Lines (10) B&W. Reanalysis has started.
