I.

Station Blackout Scenario

\\

A general description of the expected chain of events, including the automatic plant response, immediate operator actions, coping plan and shutdown of the plant after recovery of power will set the stage for the more detailed discussion to follow.

Include discussion on the systems that will (and will not) be used, expected plant temperature and pressure, sources of injection, means of heat removal and actions being taken to arrange the electrical distribution system to cope with the event.

II. AC Power design characteristics:

1.

Discussion of any plant LOOP's from 1984 to present:

This data will supplement those given in NUREG/CR-3992.

2.

EDG Configuration and reliability target: a) Past experience on gr tests and actual demands; b) EDG Reliability Programs; 1 Others.
