9 500 SOUTH 27TH STREET. DECATUR. ILUNOIS 62525 September 19, 1980 Mr. Gaston Fiorelli, Chief Reactor Construction and Engineering Support Branch U.S. Nuclear Regulatory Commission Region III 799 Roosevelt Road Glen Ellyn, Illinois 60137
Dear Mr. Fiorelli:
This is in response to your letter dated August 20, 1980, which included a Notice of Violation and Inspection Report Number 50-461/80-14.
The one item of noncompliance cited in this report states in part:
" Contrary to the above, the licensee failed to follow procedures and instructions in the implementa-tion of welding requirements of the control rod drive ho:, sing to the reactor vessel bottom head penetration,
]
in that, Reactor Controls Incorporated (RCI), Process Requirements Sheet for Reactor Pressure Vessel Internals Installation Work, Weld Number 32, required a mock-up weld using WPS 34/34-OTS-1 1G/2F position.
The Performance Qualification Records of mock-up Number WMU-32 indicated that six of the nine welders performed the mock-up using the 1G/lF position."
Investigation of this matter has shown it to be a case of documentation errors.
The CRD housing weld is actually 2F for the fillet portion of the weld and 3G for the groove portion of the weld.
All Reactor Controls Incorporated (RCI) welders per-forming CRD housing welds had been qualified in the 6G position (automatically qualifying them in the 3G position), and had per-formed additional qualification to Mock-up Procedure WMU-32.
The latter fulfilled the requiremont for the 2F, restricted access, position qualification.
Therefore, the welders performing CRD housing welds were fully qualified, however, RCI records did not reflect the proper qualifications,
$EP, 2 2 GW 8'020170 g g l
Gaston Fiorelli September 19, 1980 Specific corrective action is being taken to revise the Process Requirement Sheet and individual Performance Qualification Records to reflect the proper requirements and actual qualifications.
These records will be corrected by October 1, 1980.
To avoid recurrence of this type of documentation error, cognizant RCI personnel have been instructed on the requirement for accurately determining qualifica' ion requirements and recording them.
I trust that the above actions constitute an acceptable re-sponse and will satisfactorily complete our Corrective Action.
Sincerely, i
L J. Koch Vice President cc:
