ARLINGTON. TEXAS 70011 APR 2 81983 MEMORANDUM FOR:
Docket File 99900330, Westinghouse Switchgear Division FROM:
U. Potapovs, Chief, Vendor Program Branch, Division of Vendor and Technical Programs
SUBJECT:
MEETING ON REACTOR TRIP BREAKER PROBLEMS On April 22, 1983, a meeting was held at the Westinghouse Switchgear Division, East Pittsburgh facility between T. Ippolito, R. LaGrange, and U. Potapovs of NRC and Westinghouse personnel identified in the attached attendance list to discuss possible contributing factors to the recent malfunctions of Westinghouse Reactor Trip Breakers with under voltages (UV) devices.
This memorandum addresses primarily the quality assurance and manufacturing process control aspects of the items discussed.
Over the past several years there has been a gradual tightening of QA measures within the Switchgear Division including both procurement and manufacturing controls for Class 1E equipment.
This process is still continuing and some of the recently adopted measures have not yet been finalized in a formal QA program document with implementing procedures.
As an example, during the pre-Salem supply period, the only major difference in procurement of commercial and Class 1E switchgear components was that a certificate of compliance was issued for the 1E devices.
The significance of this certificate was primarily that special care and attention was given to these parts during assembly and testing although no additional processing or inspection requirements were applied or documented for these items as compared to parts manufactured for commercial application.
Nuclear orders (1E) could be identified by "YN" designation in the order number.
This designation, however, was applied to the entire switchgear assembly and not necessarily to the UV devices.
During the manufacturing and assembly of these devices all inspections including dimensional were performed on a sampling basis only.
(NOTE:
At least some of the recent functional problems were directly attributed to improper dimensions).
During the " post-Salem" period, the following changes were instituted in the procurement and manufacturing practices for 1E " equipment:

effective configuration control). unseated shaft retaining rings, i
3.
Critical dimensions identified for individual parts and assemblies which are required to be 100% inspected during the manufacturing pro for Class 1E components.
t While the above changes are reportedly being implemented, formal Q procedural modifications have not been completed at this time for all of thes ram /
items.
Additionally, based on a policy letter dated April Westinghouse Nuclear Service Integration Division (NS 21, 1981, all orders for i
by utilities or others directly with the Switchgear Division are returned tall i
the originator with instructions to reorder through NSID who then provid o
a technical /QA overview for the procurement of these items.
es Switchgear Division essentially as an outside vendor in the procurement NSID treats the in that they conduct QA audits, product surveillance audits process releases for specific items prior to the shipment of these items to the u and execute QA Historically, all DB undervoltage devices (manufactured from 1950'on) since 1970) have been assembled at the Puerto ve been Division providing the overall QA management function.
In summary, it would appear that the outlined changes in the manu and QA program, if properly implemented should provide reasonable as controls that the manufactured equipment will tre capable of performing its i t function.
devices appears to be the need for the purchaser to c n ended as Class 1E otherwise the order may well be filled from commercial stock em i

Memo to Docket File,
Additionally, the list of critical dimensions designated for 100% inspection should be broadened to include configuration verification (ex., proper installa-tion and seating of retaining rings) as well as at least a visual verification of the absence of significant defects in critical areas such as the cold formed tab on the trip bracket stamping.
