"10 CFR 50, Appendix B, Criterion III, requires, in part, thnt ceasures shull be established end executed to assure that regu-latory requirements end the design basis as specified in the license application for structures cre correctly translated into specifications, drevings, procedurer end instructions.
Also, it provides thct teosures shall be estsplished for the identification and control of design interft zca and for coor-dinctes econg participating design organications.
CPCo Topical Report CFC-1-A Policy No 3, Section 3.4 stctes, in part, 'the essigned lead design group or organization (ie, the N3SS supplier, A&E, supplier or CPCo) essare that designs and materials are suitable and that they comply with design criteria and reguletory requirements. '
CPCo is committed to ANSI U45 2 (1971), Section h.1, which states, in pcrt, 'reasures chell be estchliched end documented to assure thet the applicable specified design requirements, such as a design basis, regulotcry reqairements
. are correctly tranclcted into specifications, drawings, proced ures, or instruction. '
Contrcry to the above, measures did not assure that design basis s ere included in drevings end specificctions nor did they provide for the identificction end control of design interfaces.
As e result, tuo inconsistencies were identified in the license application end in other design basic documents.
Specific exemples are set forth belev.
a.
Construction specification C-2, Rev 11, dated November 16, 1978, Section 11.1 specifies caterial for prestreccing system cheathing to conform to ASTM A-366-66 or 66,'s2 gauge cold rolled carbon steel while FSAR Section 3.C.1.o.3 indicate the sheathing meterial to be meteriel meeting the requirements of ASZ4 A-53, Type E or S, crede B.
