REMOVE INSERT 36 36 37a(l) 37b 37b
-36 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, (2) to provide for the continuing availability of engineered safe quards, and (3) to ensure that the station can be maintained in the shutdown or refueling condition for extended time
-periods.
Specification. I.
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 containing 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, (SectionI.l.A)demonstrate the operability of the remaining A.C. sources
- The changes to the Technical Specification Provisions are to be implemented within 30 days from the date of Issuance of Amendment No. 68. Amendment No.
37a(1)
II. During cold shutdown or refueling conditions the following specifications shall apply:
(1) As a minimum, the following shall be operable:
- a. One Southern California Edison Company or one San Diego Gas and Electric Company high voltage transmission line to the switchyard and one transmission circuit from the.
switchyard, immediate or delayed access, to the onsite safety related distribution system, and
- b. One diesel generator (capable of automatic start) with:
gallons of fuel,
- 2. A fuel storage system containing a minimum of 37,500 gallons of fuel,
- 3. A fuel transfer pump.
- c. The associated 4,160 Volt A.C. Bus, 480 Volt A.C. Bus, two 120 Volt A.C. vital buses, and D.C. Bus.
(2) With less than the minimum required D.C. and A.C.
electrical sources specified-in II.(l) above, suspend all operations involving core alterations or positive reactivity changes.
The changes to the Technical Specification provisions are to be implemented within 30 days from the date of issuance of Amendment No. 68.
Amendment No. 68
C e station is connected electrically to the Southern California Edison Company and San Diego Gas
& Electric Company system via either of two physically independent hich voltage transmission 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 generators are provided primarily to give redundancy.for maintenance, to preclude the necessity for reactor shutdowin if one.di.esel required main tenance, and to provide protection against a failure o one of the diesel generator systems. This also eliminates the necessity for depending on one diesel cenerator to ooerate for extended periods without shutdown if it were required for post-accident conditions.
The requirement for one source of offsite power and one diesel generator to be operable during cold shutdown or refueling conditions will. provide diverse and redundant electrical power sources in order that the station can be maintained in the cold shutdown or refueling condition for extended time periods.
Additonally, this requirement will assure that operations involving core alterations or positive reactivity changes can be conducted safely.
The changes to the Technical Specification provisions are to be implemented within 30 days from the date of issuance of Amendment No.
