Contrary to Section 21.6 of 10 CFR Part 21, neither Section 206, 10 CFR Part 21, nor the permitted substitute notice were posted at the Fort Collins, Colorado, plant.

OTHER FINDINGS OR COMMENTS:
1.
Initial Management Meetino - Met with management and those persons responsible for the administration of the QA Program, explained NRC direct inspection program, organization, inspection methods, and documentation.
2.
Quality Assurance Program Review - Reviewed QA program, QA manual, general inspection procedure, and eight customer purchaser orders.
The QA manual states that the WGC QA system is equal or superior to MIL-Q-9858A.
None of the purchase orders reviewed by the inspector imposed Appendix B of 10 CFR Part 50 on WGC.
The QA program had been audited by twenty utilities and six original equipment manu-factures since 1977.
3.
Construction Deficiency Report by Duke Power Company - Problem reported was the failure of droop lever spring in governor for emergency diesels.
Three hundred-thirty droop lever springs were returned by WGC to their spring vendor because the hooks were misaligned.
The misalignment was corrected by the vendor and the springs were returned to WGC for instal-lation in governors.
A total of 308 governors with springs from this lot were shipped to customers.
Subsequently, two governors were returned to WGC for repair.
The governors were disassembled and inspected, and it was found that the droop lever springs were broken.
It was determined that these springs were from the reworked lot. WGC contacted their spring vendor and was informed that the springs had been reworked by cold bending. WGC performed vibration testing on a sample of springs from this lot which resulted in a high failure rate.
WGC notified those customers who had received the other 306 governors.
At this time, WGC redesigned and manufactured 298 springs, incorporated them in replacement kits, and sent them to the affected customers.
