In-Plant Considerations for Optimal Offsite Response to Reactor Accidents.

摘要

Offsite response decision-making methods based on in-plant conditions are developed for use during severe reactor accident situations. Dose projections are used to eliminate all LWR plant systems except the reactor core and the spent fuel storage pool from consideration for immediate offsite emergency response during accident situations. A simple plant information management scheme is developed for use in offsite response decision-making. Detailed consequence calculations performed with the CRAC2 model are used to determine the appropriate timing of offsite response implementation for a range of PWR accidents involving the reactor core. In-plant decision criteria for offsite response implementation are defined. The benefits and negative aspects of the proposed response implementation criteria are discussed in detail.
