ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 GROUTED ANCHOR INSPECTION RECORDS ARE INADEQUATE BLRD-50-438/85-07 AND BLRD-50-439/85-07 NCR 3714 10 CFR 50.55(e).
FINAL REPORT Description of Deficiency During a review of all grout cards issued to install grouted anchors at Bellefonte Nuclear Plant (ELN), it was discovered that numerous anchors were not inspected to the requirements of BLN site quality control procedure (QCP) 2.8, " Bolt Anchors Set in Hardened Concrete." However, it is evident that some of these anchors had received inspection in accordance with the specifications denoted on construction documents such as work releases 'or drawings.
The apparent cause of this deficiency was a lack of understanding of QCP 2.8 by. the applicable engineering units.
Safety Implications Failure to inspect grouted anchors in accordance with the pertinent criteria could result in the acceptance of grouted anchors that do not meet design standards. Substandard anchors could fail under design conditions and adversely affect the performance of a safety-related system, and thus the operation of the plant.
Corrective Action TVA's Office of. Engineering (OE) has evaluated all of the grouted anchor installations identified by the Office of Construction (OC) personnel and dispositioned the deficient installations. The applicable engineering units are in the process of evaluating all the grout records for adequacy based on OE's disposition. At the present time, no grout records have been rejected.
If any grout records are found to be unacceptable, the corresponding installation will be reinspected.
To prevent recurrence of this deficiency,- the responsible unit personnel will be retrained to the applicable requirements of BLN QCP 2.8, " Bolt Anchors Set in Hardened Concrete," This will be documented in accordance with BLN QCP 10.29, " Quality Assurance Training Program," and BLN QCP 10.50, "QA Training Program for Engineering Personnel." In addition, the procedure has been revised to clarify responsibilities and criteria concerning grouted anchor installation.
All actions were completed September 5, -1985.
