Subject:
Auxiliary Feedwater System Project San Onofre Nuclear Generating Station Unit 1
Reference:
A. Meeting Minutes of the June 2 and 3, 1981 Meeting.
Enclosed is the following information which your requested for the subject project:
- 1. Bechtel letter BPC/SCE-81-247 dated September 18, 1981, which provides equipment loads for the turbine building complex.
- 2. Bechtel letter BPC/SCE-81-249 dated September 21, 1981, and revised sketches 14000-073-SK-C-53 (Rev.
B) through 59 (Rev.
B) and 14000-073-SK-C-68 (Rev. A) which describe the modifications to the turbine building which are being considered inconjunction with the reevaluation of tWis structure. These sketches supercede the turbine building sketches which were provided at our June 2, 1981 meeting.
Additionally, drawings describing the modifications which are being performed to the column-girder joints of the north turbine building extension will be provided by October 15, 1981.
