BASIS:

The station is connected electrically to the Southern California Edison Company and San Diego Gas & Electric Company system via either of two physically independent high voltage transmission routes composed of four Southern California Edison Company high voltage lines and four 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 four 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 redundancy 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.

In MODES 1, 2, 3 and 4, two diesel generators provide the necessary redundancy to protect against a failure of one of the diesel generator systems or in case one diesel generator system is taken out for maintenance, without requiring a reactor shutdown. 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.

SAN ONOFRE - UNIT 1 3.7-4 AMENDMENT NO. 134

When one diesel generator is inoperable, there is an additional ACTION requirement to verify that all required systems, subsystems, trains, components and devices, that depend on the remaining OPERABLE diesel generator as a source of emergency power, are also OPERABLE. In addition, the ACTION STATEMENT requires a verification that the steam-driven auxiliary feedwater pump is OPERABLE in MODES 1, 2, and 3.

These requirements are intended to provide assurance that a loss of offsite power event will not result in a complete loss of safety function of critical systems during the period one of the diesel generators is inoperable. The term verify as used in this context means to administratively check by examining logs or other information to determine if certain components are out-of-service for maintenance or other reasons. It does not mean to perform the surveillance requirements needed to demonstrate the operability of the component.

During normal operations, the 480 volt system is considered OPERABLE if the four 480 volt buses and four station service transformers are OPERABLE with respective tie breakers open.

This will ensure that the 480V main breakers and transformers remain OPERABLE during the worst loading condition in case of a SIS without LOP.

The primary power source for Vital Buses 1, 2, 3, 3A, and 4 is Train A DC Bus 1. The alternate power source is available from MCC-2 through MTS-7. The 1987 RPS and ESF single failure analyses credited the Train B backup power to these vital buses through MTS-7.

Correct operation of the safety injection system is assured by the operability of the load sequencers and the UPS for MOV-850C and MOV-358 (MOV-850C UPS).

Correct operation of the recirculation system is assured by the operability of the MOV-850C UPS which also supplies MOV-358.

Manual Transfer Switch 8 (MTS-8) provides the means to power MOV-883 and the MOV-850C UPS from either Train A or Train B.

However, due to single failure considerations and environmental effects, MTS-8 is normally powered from MCC-4 on Train B.

MOV-883 is the discharge valve from the RWST and must remain open during the safety injection phase and close with initiation of recirculation.

3.7.2 ELECTRICAL SUPPLY:

SHUTDOWN APPLICABILITY:

MODES 5 and 6 OBJECTIVE:

To define those conditions of available electrical power to ensure that the station can be maintained in the shutdown or refueling condition for extended periods.

SPECIFICATION:

a. One Southern California Edison Company or 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 shall be OPERABLE.

b. One diesel generator shall be OPERABLE which is capable of automatic start with:

1. A day tank containing a minimum 290 gallons of fuel,

2. A fuel storage system containing a minimum of 37,500 gallons of fuel, and

3. A fuel transfer pump.

c. One train of AC buses shall be OPERABLE comprised of:

1. 4160 volt Bus IC, and 480 volt Buses 1 and 3 with at least one associated station service transformer; OR

2. 4160 volt Bus 2C, and 480 volt Buses 2 and 4 with at least one associated station service transformer.

d. 120 volt Vital Buses 1, 2, and 4 energized from associated inverters connected to DC Bus 1.

e. One 125 volt DC Bus OPERABLE and energized from the associated battery with at least one full capacity charger.

ACTION:

With less than the minimum required AC and DC electrical sources specified above, suspend all operations involving CORE ALTERATIONS or positive reactivity changes. Initiate corrective actions to energize the required electrical buses. Within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months , depressurize and vent the RCS through at least a 1.75 square inch vent.

BASIS:

In MODES 5 and 6, the requirement for one source of offsite power and one diesel generator to be OPERABLE will provide diverse and redundant electrical-power sources in order that the station can be maintained in the COLD SHUTDOWN or REFUELING condition for SAN ONOFRE - UNIT 1 3.7-6 AMENDMENT NO. 134

extended time periods. Additionally, this requirement will as sure that operations involving core alterations or positive re activity changes can be conducted safely. One SST and 480V main breaker will be capable of supplying the necessary power to the two associated 480V buses without exceeding their maximum loading ratings due to the reduced bus loading. Vital Buses 1, 2, and 4 power redundant source range nuclear instrument channels and Overpressure Mitigation System (OMS) channels and are required to support operations in MODES 5 and 6.

Temporary cross-training between the two emergency AC trains is allowed only during the outages for maintenance purposes by use of power cables provided between 480 volt Bus 4 and Bus 1. The supply 480V bus, when cross-trained, does not become inoperable.

Temporary cross-training will require two breakers in series to maintain adequate separation. In addition, the receiving bus cannot be declared OPERABLE. Loads will be added manually and limited by the operator action.
