Abstract
The NRC created a state-of-the-art reactor consequence analysis (SOARCA) project to develop the best estimates of the offsite consequences for potential severe reactor accidents for two pilot plants: the Peach Bottom Atomic Power Station and the Surry Power Station (USNRC, 2012). The short-term station blackout (STSBO) and long-term station blackout (LTSBO) were identified as the major groups of accident scenarios for analysis. Both types of SBOs involve a loss of all alternating current (AC) power. SOARCA-like analyses, which are limited to accident progression except offsite consequences, were conducted for an OPR-1000 PWR. This paper illustrates a preliminary assessment for the mitigative effectiveness of external cooling water injection strategies using fire trucks during a potential extended station blackout accident.
