ENCL'OS'URE PHIPPS BEND NUCLEAR PLANT. UNIT 1 OMITTED REBAR FROM UNIT 1 SHIELD WALL PBRD-50-553/81-09 REPORT NO. 1 (INTERIM)-
Description of Deficiency Beinforcing bars shown on C. F. Braun drawings Y-010 and Y-013 between Azimuth 105 and 1?50 were omitted'from.the reactor _ shield building.
The design drawings were not consistent between elevations. Design drawing Y-010 shows rebars terminating at an elevation 5'-2", and design drawing Y-013 shows~rebars cadwelded at an elevation of 15'-2". The apparent cause of thia deficiency was a drawing discrepancy between-design drawings. TVA inspectors, however, did not identify the discrepancy and the rebar was'placed.and inspected in accordance with drawing' Y-010','
Corrective Actions TVA will drill h' oles in the ceactor shield wall and grout in 16'-9"-long splice bars (44 #11AW), 6'-9" below elevation 5'-2". A rebar verification group has.been instituted to work directly with the construction trade forces during rebar installation'.' This group is structured within the project engineering /ci.vil unit and has the function to guide construction personnel and correct . discrepancies before they become a problem of complex nature or have reached a stage of nonconformance. Verification before final inspection should eliminate errors caused within the rebar, structure. TVA.has notified GE/C. F. Braun of this nonconforming condition and has requested they.
provide steps to be taken to prevent recurrence'of similar drawing errors.
