FIFTH INTERIM REPORT Description of Deficiency INRYCO, Incorporated, is the contractor, contract No. 75C53-85380, for supplying and installing the prestressing system for the primary containments at Bellefonte Nuclear Plant units 1 and 2.
On April 15, 1981, INRYC0 informed TVA that a shophead/ bushing failure had occurred during stressing operations on March 19, 1981 at the Braidwood Nuclear Plant and that INRYC0 had submitted a report in accordance with 10 CFR Part 21 to the Nuclear Regulatory Commission to document this failure. As a result of this failure, INRYC0 began measuring the unstressed anchorage material at Bellefonte. Several cases have been documented whereby the dimensions measured do not fall within the tolerances established by the shop fabrication manual. In some instances, the anchorage material is oversized and in other instances, the anchorage material is undersized.
Interim Progress TVA is awaiting Inryco's submittal of all anchorage measurements before finalizing a disposition of this deficiency. All anchorages are measured, and Inryco is preparing to transmit these measurements to TVA.
All NCR's concerning dimensionally nonconforming anchorage material will be hanaled under this report (BLRD-50-438/81-33, -439/81-36). To date these include 1447, 1457, 1461, 1469, 1473, 1474, 1475, 1485, 1491, 1502, 1510, 1511, 1521, 1523, 1542, 1547, 1558, 1562, 1571, 1590, 1591, 1628, 1629, 1630, 1642, 1643, 1650, 1657, 1670, 1678, 1698, 1704, 1712, and 1724.
