DETAILS SECTION A.
Persons Contacted
- C.
V. Prestowitz, Technical Director
- H. G. Meehan, Quality Assurance Manager
- Indicates personnel present at the Exit Interview (See paragraph D.).
g B.
Material Identification and Control 1.
Objective The objective of this area of the inspection was to verify that material identification and control during manufacturing is in accordance with the ASME Code and applicable NRC regulations.
2.
Method of Accomolishment The objective of this area of the inspection was accomplished by:
a.
Review of the ASME accepted Quality Assurance Manual, Revision N, dated March 1978, to verify that procedures had been established for material identification and control during manufacturing.
b.
Review of the following procedure 3.4.1, Revision J, dated November 1976, Titled " Maintenance of Wire Identification,"
to verify it provides for the identification and control of purchased materials, requires the retaining of positive identification of materials throughout the manufacturing cycle, and provides for segregation and disposition of nonconforming materials.
c.
Reviewed selective certified material test reports to verify they conformed with ASME Code requirements, applicable material specifications, and/or special requirements specified in referenced procurement documents.
d.
Examined representative material in various stages of manufactring and verified identification and traceability to the certified mill test report.
e.
Interivews with personnel to verify they were knowledgeable in the procedures applicable to material identification and control.
- 3.
Findings No deviations or unresolved items were identified.
C.
Special Meeting (Report No. 99900036/78-03.)
The purpose of this special meeting with the Arcos' Technical Director, Mr. Prestowitz, was to determine if the Combustion Engineering (CE) inconel electrode problem, identified in Report No. 99900036/78-03, is generic to other nuclear componet manufacturers.
Mr. Prestowitz explained that his organization was promptly advised of the CE identified welding problem and that he had visited the CE facilities to assist in an early resolution of the problem.
He further advised the inspector that the CE technical and management personnel had subsequently visited the Arcos facility to conduct mutual weld test plates and perform a records audit.
The inspector asked for and received a list of manufacturers that had received shipments of the suspected inconel electrodes produced by Arcos after October, 1977.
It was also verified that Arcos has not received from their customers any information relating to similar electrode problem other than CE.
However, Mr. Prestowitz did state that should his organization receive any information regarding this matter, it would be provided to CE, who in turn, will keep the NRC inspector informed. A review of material records indicated that Arcos has, at the request of CE, developed an electrode chemistry that it is believed will eliminate cracking problems identified in the CE shop. To date, several of these developed chemistry lots have been tested to the additional CE requirements, qualified, and shipped to CE for use.
As a result of the meeting it was determined that, while Arcos has supplied the CE referenced " suspect" inconel electrodes to various other nuclear componet manufacturers, generic considerations are not germaine at this time due to:
1.
The CE referenced ' suspect" inconel electrodes have met all AWS, ASME, and CE purchase order requirements and, to date, have not been conclusively proven to be the cause of the weld cracking problem.
2.
All Class I and II Componets intended for use in nuclear facilities receive one or more nondestructive examinations, any one of which readily detects the referenced weld cracking condition.
The inspector has no further questions relative to this matter at this time.
s D.
Exit Interview The inspector met with managerrent representatives (denoted in para-graph A.) at the conclusion of the inspection on October 19, 1977.
The management representatives had no further questions regarding the inspection.
