) SU:iMARY OF INVESTIGATION:
j s
This concern is not substantiated.
The investigation involved steamfitter personnel employed at the Sequoyah Nuclear. Plant during 1977-78.
FINDINGS:
An investigation at the Watts Bar Nuclear Plant (HI-85-013) substantiated an employee concern in which a
Steamfitter General Foreman had instructed steamfitter welders to repair welds contrary to requirements of the weld repair procedure.
The Steamfitter General Foreman was quoted as saying "that this (type of weld repair) was done a lot at SON, and we did not squeal on each other for doing it; we took care of one another."
This individual was employed at SON as a Steamfitter Foreman in 1977-78 cnd in 1979 he became a superintendent. Objective evidence could not be obtained that could identify individuals who may have been under the direction of the subject individual.
Interviews identified that the i
cubject individual was a-foreman of the -Hanger Fabrication Shop at SQN, i
- however, no one had direct knowledge of the content of his directions relative to improper weld repairs.

PROGRAM SUPftARIZATION OF WELD PROJECT (WP) EVALUATION This package summarizes the actions taken by the Welding Project (WP) to evaluate and disposition the subject SQN-specific employee concern which was previously evaluated by NSRS/QTC/ERT and summarized in WP Phase I and Phase II reports.
The Welding Project analyzed each SQN-specific employee concern to determine the statement (s) being voiced by these individuals.
These statements were then evaluated both individually and collectively to develop issues.
Each issue was then incorporated into the WP review activities of Phase I,
" Procedural Assessment" and Phase II, " Procedural Implementation."
Duriang Phase I, each issue was analyzed against requirements of the applicable QA program, policies, NSRS/QTC/ERT Investigation Reports, and other relevant information to determine if program elements were deficient when evaluated i
against upper-tier requirements.
Phase II consisted of a sample reinspection of hardware and independent program audit by Bechtel.
In each area analyzed by Bechtel, the auditors found no objective evidence to s'ubstantiate the employee concerns considered. The following areas directly related to employee concerns were investigated by the audit team:
1.
Walder qualification and attendant records 2.
Welder qualification and attendant on-the-job-training 3.
Welding inspections l
4.
Welding inspectors training programs 5.
Weld material traceability 6.
Welding inspections by craft personnel l
r 7.
Weld material control Each of these areas was investigated by the auditors-for both construction and operations phases.
In all cases, there was no objnctive evidence to l
substantiate the employee concerns. The audit report concludes that both construction and operations phases have had and now have a functioning Welding Quality Assurance Program which meets code, standard, and regulatory requirements and that the employee concerne considered were found to be j
-unsubstantiated and without technical merit.

d The results of the reinspection program at SQN also give another, additional verification of the Welding Quality Assurance Program for both construction and operations phases and serve to establish additional confidence in the accuracy and implementation of these programs through hardware inspections and attendant document reviews. In all cases, the components and items were found i
to be acceptable upon initial reinspection or found to be acceptable after engineering analysis.
The WP analysis of SQN-Specific Employee Concerne supplemented by the independent Bechtel Audit, reinspection of installed components and system, and independent (NSRS) overview and investigations has not revealed any significant or generic inadequacies in the welding programs for either the construction or operations phase at SQN which have been directly identified through the Employee Concern Program. The Employee' Concern Program has simply reiterated problems which have been or are now being resolved through existing corrective action programs in the overall Nuclear Quality Assurance Program.
A summary analysis of the WP evaluations and recomm6ndations is included in Attachment.
