Response to NRC Report No. 50-341/78-14 Statement of infraction 78-14-02 Paragraph 4 (a-d)
Infraction:
. Contrary to 10CFR50, Appendix B, Criteria XVI, the Wismer and Becker Company (W & B) failed to take adequate corrective action to correct deficiencies identified on both Parson and Wismer and Becker Installed pipe hangers.
In addition, no plans exist to prevent recurrence.
Corrective Action Taken and Results Achieved The Halt Work Directive, which was issued at the time of your inspection, to stop work on Q.A. Level I hangers is still in effect.
As a result of issuing the Stop Work Directive, two (2) basic requirements were imposed on the Wismer and Becker (W & B) construction personnel involved with the hanger program.
The following requirements will be complied with prior to releasing the Halt Work Directive:
1.
Additional training in the requirements of the revised procedure will be given to the responsible personnel from the Superinterdent/ Foreman level down to the personnel actually performing installation activities.
2.
Proficiency at installing hangers correctly must be demonstrated in limited quantities, initially in groups of ten (10), before any additional hangers are released for installation.
(10) hangers have been accepted and ten (10) hangers are As of this date, ten The inspection of hangers in groups of ten (10) will currently being installed.
be continued until a high confidence level is obtained in the quality of the work being performed.
Procedure WB-C-Il4 (Field Fabrication and Erection of Pipe Hangers and Restraints) is currently being revised by a task force of Edison, Daniel, and W & B personnel.
An audit of the W & B hanger program was completed by the Edison site Q.A. auditors on October 10, 1978.
A schedule for audits has been formalized for the balance of 1978.
Corrective Action Taken to Avoid Further Noncompliance Wismer and Becker Procedure WB-C-Il4 is being reviewed and extensively rewritten at this time.
Wismer and Becker Q.C. will do a final acceptance inspection as per the checklist in Wismer and Becker Procedure WB-C-ll4.
If the final Q.C. acceptance inspection U

,y,
- yields a rejectable hanger, the procedure will state that a Deviation Disposition Request (DDR) or a Surveillance Report i s to be generated.
A 30-day turnaround period will be allowed for initiation of corrective action necessary to repelr, rework, or replace deficient hangers.
Specification 3071-31 will be revised by a Design Change Request (DCR) to clarify allowable weld tolerances.
In addition, a program is being devised which will assure that Q.C. Inspectors have adequate knowledge of specified welding tolerances prior to starting work.
DDR and Surveillance Report results will be included in trend analysis to alert management of the need for them to take action.
Date When Full Compliance Will be Achieved The revised procedure WB-C-Il4 is expected to be approved and implemented by November 1, 1978.
The new training program will be implemented by November 30, 1978.
