.VI'OLATION Is I 10 CFRL50', Appendix B, Criterion V, requires' that activities.af fecting

. quality be prescribed by a'ppropriate procedures and accomplished in accordance with these procedures.

.Bechtel Power' Corporation, Job Rule M-21 is the procedure established to provide direction ~ to construction personnel regarding cleanliness controls on systeas which have been turned-over to the licensee's Startup Organization.

Contrary to the above,' as of November 30, 1983, Job Rule M-21 had not been ef fectively implemented as evidenced by the f ailure to provide suitable cleanliness controls following disassembly of' a feedwater system contairment isolation valve IN41-1F010A. The valve body was ,

open, the internal surfaces of- the valve anJ its atuched piping were exposed to tha containment; environment, and standing water of undetermined quality had accumulated in the valve.

RESPONSE TO VIOLATION I Cleanliness controls associated with the identified valve and for

- Startup Work. Orders in progress at that time were corrected as' necessary to identify cleanliness- requirements _ to meet the. requirements 1 of Job Eule M-21.

To prevent recurrence of this condition, several! actions have been taken:

1)~ Post Turnover Maintenance field engineers, superintendents, and craf t personnel have been reinstructed in.the; requirements 3 of Job. Rule M-21 (Performing Work on Flushed Systems) .

2) Job Rules which contain references to Post Turnover -Maintenance have been revised 'to also apply to Startup Work Orders.
3) A Quality' Control Engineer hasbeen assigned full' time to -

oversee construction and housekeeping practices associated

. with the requirements' of , Job Rule M-21.~ '

j RESPONSE TO APPENDIX A .;

VIOLATION 2

- 10 CFR 50, Appendix B, Criterion X requires the establishment of a program that assures that examinations, measurements, or tests of caterials or products processed be performed for each- work operation where necessary to assure quality. .

I Section.17.2A.10.of the Final Safety Analysis Report and Volume I, Section 10 of the Limerick Generating Station Quality Assurance Plan establish this program.

Contrary to the above, the progra n establishe.d for engineering and quality inspection of pipe support hangers failed to assure the quality of two -saf ety-related hangers in- that, _as of Novenber 7,1983, hangers VRR-IRS-HHA-1 and HHB-1, for ths reactor recirculation sys tem suction piping were inadequately designad and installed and the inadequacies were not . identified during the engineering and quality inspections which

, had been completed.
RESPONSE'TO VIOLATION 2 The interferences identified by the Inspector did not develop until' af ter Field Engineering and QC acceptance of HHB-1 and Field Engineering release for pre-ops of HHA-1. These interferences developed as a result of the vibration caused by the recire pump operation. . However, . subsequent

- to the interferences developing, Field Engineering performed rework on '

hanger .HHB-1 which QC inspected. The rework was limited- and did not

involve the interfering members of .the support. The interferences were .

not identified because of the apparently limited inspection of the-reworked hanger.. '

s .

The Inspector identified interferences have been resolved by implementing l

p tan option which was included in an FDDR prior to the interference- being; -

L Identified. The option was not used durit.g initial installation because i the. Field Engineers did not foresee the developement of the interferences.

t

i. To determine the ~ extent of' this condition QC completed inspectbns of the:

24 GE designed recirculation and unin steam hangers. These inspections '

U identified several nonconf ormances, the majority of which result from the lack of installation tolerances. Investigation into the-cause of -

these nonconf ormances - is..'not complete.: Theref ore, a follow-up response 4 to this violation will be.made by;3/31/84. ,

. RESPONSE TO APPENDIX A VIOLATION 3' 10 CFR 50, Appendix B, Criterion <V requires .that activities affecting quality be prescribed by documented procedures and accomplished in accordance with the established procedures.

' Project procedure PSP-G-3.1 specifies nonconformance reporting requirements

.and permits oniv one nonconforming condition to be reported in each noncon-formance report (NCR).-

Contrary to the above, the project nrocedure for NCR reporting was not followed in that. as of November ~ 30, 1983, NCR 6507 was revised to include additional nonconformances.

RESPONSE ~TO VIOLATION 3 j

The additions made to Nonconformance Report (NCR) No. 6507, although admittedly not provided for in the existing procedure, did document the nonconforming conditions and associated dispositions to adequately meet the requirements -

of 10 CFR 50, Appendix'B, Criterion XV.

To prevent recurrence and to provide for the.various situations encountered during the processing of Nonconformance Reports.(NCR's), Project Procedure 3

PSP-G-3.1.was revised to provide for reprocessing the original NCR if the existing condition was not resolved or if a new condition was created by the disposition. .The PSP was also revised-to require a.new NCR be gen-l' erated when additional nonconforming items are' discovered. The exact i instructions in the PSP are:

- "If ~" Rework" or " Repair" performed to .the original disposition did not satisfactorily resolve the existing condition
or created a' new condition, the Construction Quality Control Engin4er per-forming _ the reinspection shall document the results as a revision l to block 19 of the NCR form, and reprocess the NCR for additional disposition.

i If ' additional nonconforming items are discovered as a result of ~

the reinspection, a new Nonconformance Report shall-be initiated.

VIOLATION 2 i j

10 CFR 50, Appendix B, Criterion X requires the establishment of' a d program that assures that examinations, measu rements , or testn of materials or products processed be performed for each work operation where necessary to assure quality.

Sec tion 17.2A.10 of the l'inal Safet y Analynin Report and Volume I, Section 10 of the Limerick Cunerating Station Quality Assurance Plan ectablish this program.

Contrary to the above, the progmm established for engineering and assure the quality quality inspec tion of pipe sup.iort hangers f ailed tu of two saf ety-related hangers in that, as of Novanber 7,1983, hangers VRR-IRS-IlllA-1 and lillB-1, fur the reae tor reeI reulatIon synien sue tlun piping were inadequately designed and installed und the inadequ.seles were not identified during the engineering and quality inspections which had Seen completed.

HMSPONSM TO VIOI.ATJON 2 The interferences identified by the Inspector did not develop until af ter Field Engineering and QC aeceptance of 111lll-1 and Field Hngineering release for pre-ups of IlllA-1. These interf erences developed as a result

' of the vibration caused by the recire pump operation, llowever , subsequent to the interferences developing, Field Mngineering performed rework on innger 11118 - 1 which QC Inspected. The rework was limited and did not.

Involve the interfering members of the suppor't. '?he interferences were not identified .because of the apparently limited :41spection of the reworked hr.nger.

The Inspector identified interferences have been resuived by implementing an option which una included in an FDDR prior to the interference being identified. The option was not used during initial installation because

- the Field Engineers did not focusee the developement of the interferences.

To determine the extent of this condition QC completed inspections of the 4

24 GE designed recirculation and unin steam hangers. These inspections identified several. nonconf ormances, the majority of which result from the lack of installation tolerances. Investigation into the cause of these nonconformances is not complete. Therefore, a follow-up response -

to this violation will be made by 3/31/84.
