b. 480 V Load shedding b. 256 volts +3%

Time delay: <0.75 sec. +10s at 0 volts 13.5 sec. +20 at 90% of i voltage setting

    • Within 6 months of the effective date of this amendment (January 11, 1982) the licensee will submit further justification for this voltage setpoint and time delay or a proposed Technical Specification change for Units 1 and 2. The January 11, 1982 effective date is for Unit 1 only. For Unit 2 this limit is effective upon installation' of the associated relays but in no case la'ter than upon return to power from the spring 1982 refueling outage.
