APPENDIX A NOTICE OF VIOLATION Tennessee Valley Authority License Nos. CPPR-162 Phipps Bend
& CPPR-163 Based on the NRC inspection November 5-8, 1979, certain of your activities were apparently not conducted in full compliance with NRC requirements as indicated below. These items have been categorized as described in correspondence to you dated December 31, 1974.
As required by Criterion V of Appendix B to 10 CFR 50, implemented by PSAR Section 17.1A.5, " Activities affecting quality shall be prescribed by docu-mented instructions, procedures or drawings...and shall be accomplished in accordance with these instructions, procedures, or drawings." Procedure QCI-C-208 specifies that concrete cylinders shall be stored in accordance with requirements of ASTM C-31.
ASTM C-31 requires cylinders to be moist cured until time of testing. ASTM C-31 defines moist curing as a condition in which the concrete cylinders have free water maintained on the entire surface at all times. Procedure QCI C-208 specifies that concrete test cylinders shall be tested in accordance with requirements of ASTM C-39.
ASTM C-39 requires that the rate of loading during testing of the concrete cylinders be applied within the range of 20 to 50 psi per second.
Contrary to the above, the following examples of failure to follow procedures were identfiied.
1.
On November 7, 1979, the surfaces of concrete cylinder numbers 1308 F, 1371 E, 1371 F, 1378 E, 1378 F and 1434 F stored in the concrete laboratory curing room were dry.
2.
On November 7, 1979, during testing of concrete cylinder numbers 1174 E, 1173 F, 1175 E, 1175 F, 1176 E, 1176 F, and 1170 E, the rate of loading was applied in the range of 60 to 70 psi per second.
This is a deficiency.
