ELECTRICAL EMERGENCY 1.

PURPOSE To provide the subsequent operator actions which must be accomplished in the event of an Electrical Emergency (AC or DC) which causes a reactor trip.

These actions are taken after completion cf the Standara Post Trip Actions and an electrical emergency has been diagnosed.

The actions in this procedure are necessary to ensure that the plant results in a stable safe condition.

2.

ENTRY CONDITIONS a.

The Standard Post Trip Actions have been Derformed O

and a

b.

Plant conditions indicate that an electrical emergency has occurred by one or more of the following i

i.

Failure of NSST to properly transfer to RSST (C08) 11.

"Breaker Tripped" alarms on 6.9 and 4.16 KV buses (C08) 11.

Auto start of diesel generatur(s) (C08) iv.

Loss of all RCPs (CO3) i l

v.

Reactor trips but half the TCBs indicate open and half have no indication (C04/RPS) vi.

125V DC Trouble Alarms (C08) vii. Extensive loss of various indications 7

e Instructions Contingency Actions CAUTIONS 1.

Do not rt;-energize Bus 201A or 2018 by closing 125VOC Load Center Tie Breakers 00104 and 00204 as this could result in breakers opening on the energized Bus.

2.

If the Load Center feed Breaker trips while attempting to re-energize the 125 VOC load center, do not attempt to re-energize again until the cause is determined and corrected or isolated.

3.

The diesel on the affected facility will start on loss of DC and operate at minimum speed on the mechanical governor.

There will be no diesel protection exceot for. mechanical overspeed.

The purpose of this form is to ensure that all necessary information is reviewed when using E0P 2528 Electrical Emergency.

The safety function status check verifies by independent assessment that the operator is using the correct procedure. It also assures that the procedure is satisfying all relevant safety functions and maintaining adequate core cooling.

2.

Safety function status is considered satisfied when all of the parameters of any one condition meet their criteria, 3.

With the integrated computer system functional, the safety function status may be determined from the SPDS displays.

The SS/SCO shall ensure the correct recovery E0P number is selected at the SPDS CRT.

The safety O

function status should be logged below approximately every 10 minutes V

until plant conditions stabilize.

Safety Function Status (YES/NO)

Reactivity Inventory Pressure Heat Removal Containment Integrity Vital Auxiliaries l

Time 4.

If the integrated computer system is not functional, then completion of the rest of this form is necessary at approximately 10 minute intervals until the plant conditions stabilize.

5.

Parameters marked with an asterisk require meter readings to be logged.

All other parameters are responded to by yes or no.
