States Terminal B3cck disconnect link failures were identified by CPCo during the elcetrical checkout of non-O-listed start-up transformer (0XO3A). Thirty-eight (38) individual dis-connect links out of 156 examined were found to be cracked..

Subsequent investigation by Bechtel on four cubicles in 4160 volt' Switchgear 2A06 revealed seven individual States Terminal Blocks with cracked disconnect links (refertv2ce NCR 2362 issued 7/20/79._ The blocks are identifled as follows: (Continued on page 2 of 2)

• RECOMMENDED ACTION (Optional)

1. Determine what effects cracked links in States Ter=inal Blocks could have on plant safety if uncorrected.

2. Determine cause for the cracked disconnect links.

3. Determine magnitude of problem.

4. Based on the above (3) ite=s determine reportability under 10 CTP, 50.55e.(Continued on page 2 of 2)
