Biweekly Report of RFR, Ines Activities

. Regarding PGSE Independent Audit, Phase I, February 9, 1982 through February 23, 1982

-1 ~ A

Dear Mr. Cloud:

P This report covers our activities through February 23, 1982, with 'regard to our independent Quality Assurance reviews of the Diablo Canyon Unit 1 Plant.

~ ~

To summarize our activities to date, we have completed

.the 'ollowing steps in our review of the quality assurance programs of PGKE and the six primary organizations performing seismic safety-related design work under subcontract to PGEE:

(1) We have completed our reviews of PGSE's and the six subcontractors'uality assurance program manuals and procedures, using the Program Review Checklist included in our December 19, 1981 biweekly progress report.

(2) Lists of questions were generated as a result of the program reviews, and were presented to PGKE and the subcontractors, in preparation for program implementation audits. The questions were designed to clarify non-specific areas of the program manuals and to assist the audited organizations in understanding the scope of the audits to be performed. The lists of questions.

were included in our December 19, 1981 and January 4, 1982 biweekly progress reports.

(3) Detailed Audit Checklists were generated in preparation for our program implementation audits

'of PGSE and the six subcontractors. The Audit Checklists for ANCO Engineers and EDS Nuclear were included in our January 4, 1982 biweekly progress report, and the Audit Checklists for EES (Cygna), WYLE, URS/Blume, and Harding Lawson Roger I'. Rcccly, P.H. Englllccflllg Colllllllullg

~ ~

Robert L. Cloud February 23, 1982 Page Two Associates were included in our January 12, 1982 biweekly progress report. The Audit. Checklist for PGKE was included in our February 9, 1982 biweekly progress report.

(4) We have completed the design service contractor implementation audits. The Audit Reports for EDS ahd ,Harding-Lawson Associates were completed and forwarded on -January 26, 1982. 'he Audit Reports for EES, URS/Blume, WYLE, and ANCO are currently in preparation, and are nearly complete. The implementation audit of PGSE is also nearing completion..-

--Appendix A shows our schedule for completion of the implementation audits and audit reports for Phase X, as of this date.

Revision 2 P105-4 February 24, 1982 Error and Open Item Classification 1.0 Definitions An Open Item is a possible error or inconsistency that has not been veri'fied, fully understood and its signi-ficance assessed.

-1.2 An error is an incorrect result that has been verified as such. It may be due to any of. several reasons:

mathematical mistake use of wrong analytical method omission of data use of inapplicable data 1.3 Class'A An error is considered Class A if design criteria or operating limits of safety related equipment are exceeded as a result, and changes in design or operating procedures are required.

1.4 Class B An error is considered Class B if design criteria or operating limits of safety related equipment are exceeded, but are resolvable by means of more realistic calculations or retesting-~

1.5 Class C An error is considered Class C if incorrect

~ ~

t A

R'evision 2 P105-4 February 24, 1982 engineering or installation of safety related equipment is found, but no design criteria or operating limits are exceeded.

1.6 Class D An error or Open Xtem is considered Class D if safety related equipment is not affected.

ERROR AND OPEN XTEH PROCEDURE APPLICATION A. An Error and'pen Item Repoxt (EOI Repox.t, see Appendix 2)

-wil.l be fox l5% or;,greater differences in, analysis after'he RLCA'analysis has been checked and compaxed to the PGandE woxk.

An EOI Report will be filled out for differences (defined separately) between PGandE design and RLCA. as-built in-P formation after t:he specific item has been checked in the I'C field. In addition, the incorrect value will be checked I for use in the PGandE qualification calculation or against the'GandE as-built drawings.

C. An EOI Report will be filled out in other situations (spectxal differences, examination of PGandH criteria, allowables. exceeded, etc.) as necessary.

REPORT PROCEDURES (These same basic procedur'es are applicable to QA Findings and Observations)

A. The EOI classification will be determined by the criteria in the "Error and Open Item Classification".

B- A list of items needed to close'resolve) an open item will be included in the EOI Report.

Revision 3 P105=4 February 24, 1982 C. All EOI Repoxts will be signed by an RLCA engineer. The Project Engineer will check all EOI Reports.

D.. A separate:sequential file number .will.be assigned to each EOI Report. Each EOI Repoxt is a logged and controlled document.

E. All EOI Reports will be issued as Revision 0. Any'ub-sequent changes ,. to the EOI Report will be noted by the issuance of a revision. This revision will be reported in the same manner as an EOI Report Revision 0.

'. DOCUPIENTATION A.. Each EOI Repoxt will have an individual file.

B. Each EOI Report will be released immediately to PGandE under a transmittal cover. The transmittal date will be noted on the report.

C. All EOI Reports will be attached and noted in the following RLCA Progress Repoxts.

D. All meetings and telephone convexsations wherein resolu-tion information is discussed will be documented and included in the file.

E. Copies of all documents used to resolve the error or.

open item will be included in the file.

FINAL RESOLUTION A. Resolution information will be sent to RLCA pxior to Final Resolution.

j r 'i c

1'M ~'S 0

Revision 3 + P 105- iI Rebruaxy 24, 1982 B. The Project:Engineer -; will checkc the EOX Report for resolution and adequate documentation. klis signature will appeax on the sheet and indicate RLCA approval Vi W of the resolution.

V %  !

C. The Final Resolution of an EOI will either be an error, deviation or closed item.

The error definitions are contained in the "Error and Open Item Classification"..

2.. A deviation is not an exxox in analysis, design or construction, it is a departure from standaxd procedure.

3. A closed item will result when the item identified in the EOX is found to be correct.
