BELLEFONTE NUCLEAR PLANT UNITS 1 AND.2 B&W PLANT INTERNAL BOLT FAILURES BLRD-50-438/83-35, BLRD-50-439/83-31 l

10 CFR 50.55(e)

NCR R-30 FIRST INTERIM REPORT Description of Deficiency The Babcock and Wilcox (B&W) Owners Group has opened issue R-30 " Internals Bolting Failures" documenting a potential safety concern with B&W plants.

Specifically, there have been failures or A-286 bolts used in various reactor internals applications at Oconee-1, Rancho Seco and Crystal River-3 Although B&W contends that the problem is not applicable to Bellefonte, TVA has questioned B&W's determination and is awaiting a reply from B&W. Until such time that R-30 is determined to not be a concern at Bellefonte, TVA considers the condition to be a potentially reportable nonconformance. Consequently, this NCR is intended to track the potential concern for Bellefonte.

Interim Progress B&W and the B&W Owners Group are assessing the situation to determine the scope of the problem and recommended corrective actions. TVA will provide additional details upon conclusion of this review.
