20555 IE Bulletin No. 80-02 Date:
January 21, 1980 Page 1 of 2 INADEQUATE OUALITY ASSURANCE FOR NUCLEAR SUPPLIED E0UIPMENT Description of Circumstances:
The Marvin Engineering Company (MEC) of Inglewood, California was the subject of a special NRC inspection conducted on September 18-21, 1979 to evaluate their overall QA and QC programs which had come under severe criticism by a former Marvin Engineering employee.
The special inspection was judged necessary since the Marvin Engineering Company was a known subcontractor and supplier to General Electric of BWR reactor internal feedwater spargers and feedwater thermal sleeves.
The results of the NRC's inspection established that serious deficiencies exist in the implementation of the MEC quality assura.1ce program relative to the manufacture of these components.
During this inspection, twenty seven deviations from applicable codes, and contractual and regulatory requirements were documented in the areas of material identification and control, process control, welding and nondestructive examination.
Corrective Action The Marvin Engineering Company has been issued the NRC's detailed inspection report of the Company, and given 30 days to inform the NRC how the deviations discussed in the report will be corrected and preventive action taken.
Action To Be Taken All BWR licensees and construction permit holders shall supply the following information within 90 days for operating plants and 120 days for plants under construction.
1.a. Have reactor feedwater spargers and thermal sleeves manufactured and/or fabricated by the Marvin Engineering Company been purchased and/or installed in your facility? Since Marvin Engineering is principally a subcontracting Company, determine if your equipment originated with the Marvin Company and was eventually supplied to your facility through another contractor /sup-plier.
1.b. Provide a description of this equipment to include its purchase date and its design function during both normal and accident conditions.

For each piece of identified equipment, provide the performance history associated with its usage.
This should ir.clude the cause of any failures or malfunctions and the frequency of such events.
3.
Provide information on the suppliers and receiver's QA/QC program in effect at the time of purchase.
This information should be discussed in terms of it providing sufficient bases for judging that the integrity of the equipment is sufficient to permit plant operation during normal and accident conditions.
Approved by GAO, B180225 (R0072); clearance expires 7-31-80 Approval was given under a blanket clearance specifically for identified generic problems.
