Subject:
Submittal Supporting Accelerated ABWR Schedule - P&R Comment Incorporation on Technical Specification LC0 3.8.1, AC Sources-Operating
Dear Chet:
Enclosed find Technical Specification LC0 3.8.1, AC Sources-0perat',ng. This version incorporates review comments discussed between GE and NRC staff on 9/30/93 in San Jose. We have added a new Condition to address the inoperability of one unit auxilary transformer, as discussed during the meeting in a telecon with Messrs. John Knox and Jim Lazevnick.
We have also enclosed a load list for the CVCF 120 VAC and the DC loads. We would like to arrange a conference call to discuss these loads and the effect of power loss and the appropriate A0Ts for the electrical technical specifications. It is important to have A0T consistency between the electrical LCOs, the C&I LCOs, and the supported or actuated system A0Ts. For the ABWR, great improvements have been made in the areas of redundant safety systems and instrumentation and controls for these systems. Traditional A0Ts for the electrical system LCOs l'ased on a typical BWR/6 are not entirely applicable.
Please provide a copy of this transmittal to Mark Reinhart, Jim Lazevnick, and ,
John Knox.
i Sincerely,
