o ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 FAILURE TO PERFORM ANALYSIS CHECKS ON IS0 METRICS AND LOAD TABLES BLRD-50-438/82-75 AND BLRD-50-439/82-69 NCR BLN CEB 8215 10 CFR 50.55(e)
FOURTH INTERIM REPORT Description of Deficiency Problems N4-1KE-F, N4-2KE-F, N4-1NK-B, and N4-2NK-B isometrics and load tables were signed out and issued befbre the analysis check was performed.
On problems N4-1KE-F and N4-2KE-F, the analysis check has now been performed and several analysis errors have been found which are significant. The cited isometrics and load tables are used in the design of essential c:w cooling water (ERCW) pipe supports and reactor coolant drains and vents (NK) cystem supports.
The cause of this deficiency can be attributed to a lack of procedural controls on checking activities.
Interim Progress TVA has completed the review of most of the problems within the scope of this de ficiency. Some support redesign has been required as a result of our review. However, TVA has not reviewed problems N4-1NK-E and N4-2NK-E, which were included in the scop.e of this nonconformance in our third report.
The rigorous analysis handbook has been updated to include a policy statement (section X, policy statement 21) which clarifies the items requiring completion before management review and endorsement.
TVA will provide a final report documenting our review of these problems upon completion but no later than six months before fuel load.
