NCRs -R-30 AND BLN NEB 8413 THIRD INTERIM REPORT
'Descriotion 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 of 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 As indicated in the second interim report on this deficiency, TVA is proceeding with the replacement of all A-286 bolts in reactor internals applications. B&W has submitted portions of the field' d1ange package (FCP) required for the replacement of the unit 1 A-286 material. TVA will submit a final report upon receipt, review, and approval of the entire units 1 and 2 FCPs.
