3.7 AUXILIARY ELECTRICAL SUPPLY Applicability: Applies to the availability of electrical power for the operation of plant auxiliaries.
Objective:
To define those,conditions of electrical power availability necessary (1) to provide for safe reactor operation and (2) to provide for the continuing availability of engineered safeguards.
Secificaticn:
The reactor shall not be made critical or maintained critical unless the following conditions are met:
- 1.
As a minimum the following shall be operable:
A. One Southern California Edison Company and one San Diego Gas & Electric Company high voltage transmission line.
B.- Two separate and independent diesel generators each with:
(1) A separate day tank containing a minimum of.290 gallons of fuel,
.(2)
A separate..fuel storage system con taining a minimum of 37,500 gallons of fuel, and (3) A separate fuel.transfer pump.
C.
AC Distribution (1) 4160 Volt Bus lC and 2C,
- 2) 480 Volt Bus No.
1, Bus No.
2, and Bus No.
3 (3) Any 3 of vital buses 1, 2, 3, and 4.
D. DC Bus No. 1 and DC Bus No. 2 (including at least one full capacity charger and supply per bus).
- 2.
Action A. With one of the required incoming transmission lines inoperable, (Section l.A) demonstrate the operability of the remaining A.C. sources Amendment.1o. ?!. 52
- 37b Basis:
The station is connected electrically to the Southern California Edison Compan' and San Diego Gas
& Electric Company system via either of two physically independent high voltage tcansmission routes composed of four Southern California Edison Company high voltage lines and of a minimum of three San Diego Gas & Electric Company high voltage lines.
Of the four Southern California Edison Company lines, any one can serve as a source of power to the station auxiliaries at any time. Similarly, any of the three San Diego Gas &
Electric Company lines can serve as a source of power to the station auxiliaries at any time. By specifying one transmission line from each of the two physically independent high voltage transmission routes, redundancy of sources of auxiliary power for an orderly shutdown is provided.
Similarly, either transformer.A or B, along with transformer C provide redundahcy of 4160 volt power to the auxiliary equipment, and in particular to the safety injection trains. In addition, each 4160 volt bus has an onsite diesel generator as backup.
Two diesel aenerators are provided primarily to give redundancy for maintenance, to preclude the necessity for reactor shutdown if one diesel required main tenance, and to provide protection against a failure of one of the diesel generator systems. This also eliminates the necessity for depending on one diesel generator to operate for extended periods without shutdown if it were required for post-accident conditions.
