INDEPENDENT DESIGN REVIEW OF LIERICK GBIERATING STATION #1 CORE SPRAY SYSTEM

.Bi-Monthly Status Report #3 Period Ending June 30, 1984 Introduction Eis report docu-his is the third of six planned bi-monthly status reports.

ments information concerning the independent design review of Limerick's Core Spray - System.

Be work performed covers the period June 16, 1984 to June 30, 1984.

N Sumary Be design procedure, design doctmient implmentation, and technical reviews are progressing and have increased in intensity with the addition of five temporary reviewers. A site visit was made to GE for Task A work to define this During the structure visit the of GE design control procedures applicable to the CSS.

implementation of procedures for design control audits was reviewed as rcquired in Task B.

A good portion of the Task C technical review for GE involved features must be conducted at the GE facility since they will not tronanit calculations, vendor reports, or electrical instrunentation drawings. Bis is further complicated by having to review calculations on microfilm or waiting for microfilm reproduc-tion.

De walkdown to determine the physical installation of selected portions of the CSS is complete with the internal summary report issued June 22, 1984.

To date, six potential findings have been initiated and are being processed as required by TPr's procedure. All have been sent to the original design-organi-zation, Bechtel, for their review and response.

Specific detailed status on each task follows:

reviewers visited GE the week of June 25, 1984 to establish the detailed structure of the design control procedures applicable to the CSS.

'A3 Bechtel and some GE procedures were transitted to TPI the week of June 18, 1984 The staff reviewers, mentioned in A2, returned with additional procedures identified during their visit. ,

A4 Bechtel design procedures are being reviewed under AS.

conformance is nearin6 completion.

l A6 Early procedure revisions are being obtained fra Bechtel and GE.

A7 No activity to date.

Task B DesiFn Procedure Imolementation Review B1 Complete - Procedure 2524-PD-2 issued.

B2 Docment ~1ists are being developed for Bechtel and GE and for specific design docments subjected to PECo review.

B3 Activity being coordinated with Gil.

Bil Review of PECo's design control audit activity was completed. Implementa-tion of GE procedures for design control audits was reviewed during the visit to GE.

B5 No activity to date.

_ Task C Technical Review C1 Complete - Procedure 2524-PD-3 issued.

C2 Completion of the design chain will be delayed until all vendors have been identified. De receipt of design docments continues as noted in C4 belcw.

C4 he Bechtel design docments that were initially requested but on hold pending execution of the nondisclosure agrement have been received during this report period. Additional docments identified as the review progresses are being obtained.

De visit to GE's facilities to screen and obtain doctuents required frm GE to initiate the review of the NSSS supplied components in the core Many of the doctments were available and spray system was productive.

were hand carried to San Diego..

However, all. calculations, vendor reports,Sme and of electrical instrmentation the analyses which are drawings will have to be reviewed at GE.

on microfilm will require one to four weeks to reproduce before they are available for review.

the contairment penetration De technical review of ASME Class 1 piping,Se review of Class 2 piping, pipe and selected instruments continues. the reactor vessel supports, the core spray pmp and ptmp anchorage, nozzle, core spray piping inside the containment, core spray sparger, and several valves in the core spray line were initiated.

O

- Many of the GE analyses for Limerick components refer to similar Verifica- analyses previously tion of similarity, performed for comparable components in other plants. cou docments discussed above, may impact the scheduled completion date for Task C. Expected doctmenation difficulties will be monitored by feature to eliminate or minimize any schedule impact.

C5 No activity to date.

C6 No activity to date.
