Re: Oconee Unit 1 Docket No. 50-269
Dear Mr. Giambusso:
On November 25, 1974, the annual in=pection of Oconee Unit 1 Reactor Building was completed, pursuant to Technical Specification 4.1.1.4.
The inspection was performed in accordance with approved test pro-cedure PT/0/A/0150/16, Reactor Building Inspection Test.
A visual examination was made of accessible interior and exterior surfaces of the containment structure and its components. The following are discrepancies found during the inspection:
(1) Three surface cracks were found on the bottom surface of the Reactor Building base slab. These cracks appear to be shrinkage cracks and have not shown any displa?ement. They will be re-checked during the next annual inspect? n of the Reactor Building.
(2) Several tendon grease caps were found to have grease leakage around gaskets, caps and filler plugs. The grease caps are being repaired by applying a sealant tape to the grease plug threads and retorquing the bolts.
From this inspection no evidence of deterioration was found which could affect the containment's structural integrity or leak tightness.
Very truly yours, f
