10 CFR 50, Appendix B, Criterion 111, as implemented by Commonwealth Edison Company's Quality Assurance Manual, Quality Requirement 3.0, requires that:
a.
Measures shall provide for the verification and the checking of the adequacy of a design such as by the performance of design reviews or by the use of alternate or simplified calculational methods, b.
Design changes, including field changes, shall be subject to design control measures commensurate with those applied to the original design.
l ASME NQA1 " Quality Assurance Program Requirements for Nuclear Facilities, L
Supplement 35-1", Section 4, Design Verification, states that:
a.
Measures shall be applied to verify the adequacy of design.
i b.
Results of design verification efforts shall be clearly documented.
c.
Acceptable verification methods include but are not limited to:
design reviews, alternate calculations, or qualification testing.
l Contrary to the above, the licensee failed to:
Identify durin l
a.
Reviews (OSR) g the design review process documented in the On-Site for calculation 19-D-15 that the minimum temperature correction factor for the 125 Vdc station battery electrolyte did not agree with the Technical Specifications. As a result of the incorrect temperature correction factor, Byron Batteries 111, 112 and 212 were not designed at the proper size for a DC crosstie configuration between Unit 1 and 2 with a minimum electrolyte temperature of 60 degrees F. as specified in the Byron's Technical Specification.
b.
Review calculation 19-D-15, that was utilized to justify Battery 111 l
operability with 57 cells versus 58 cells, prior to the calculation's use in an OSR. The review and approval was approximately 7 weeks after the calculation was used in OSR 89-127 for determining Battery 111 operability with 57 cells.
