ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 IMPROPER USE OF ALTERNATE ANALYSIS FOR ELBOLETS NCR BLN BLP 8231 BLRD-50-438/82-78, BLRD-50-439/82-72 10 CFR 50.55(e)
THIRD INTERIM REPORT Description of Deficiency During design review, it was discovered that Bellefonte alternate analysis calculation BLN-KC-D053-11, which concerns the Component Cooling System, contains an elbolet. The Bellefonte Nuclear Plant Alternate Criteria for Piping Analysis and Support (CEB 76-11), which is the basis for this calculation, excludes any component from its scope which is not specifically listed in appendix E (Stress Intensification Factors).
Elbolets are not listed.
Interim Progress All cases where piping containing an elbolet was qualified by the Bellefonte Nuclear Plant Alternate Criteria for Piping Analysis and Support have been identified. In each case, the piping is being rerouted to eliminate the elbolet and the analysis is being revised to reflect the new pipe route.
