 Main control room abandonment (MCRA) is a special case of fire HRA. While NUREG-1921 briefly touched upon this subject, additional research was undertaken to better address a number of factors important to the success of performing shutdown from outside the MCR, including the plant strategy and procedure, capabilities of the remote shutdown panel, and the number of local operator actions.

 ===Purpose===
-This task describes the procedure for evaluating the impact of fire scenarios on the human actions addressed in the base PRA study (i.e., the Internal Events PRA or original Fire IPEEE analysis) used to create the Fire PRA Model, as well as how to identify and quantify new  actions to be performed as part of the plant fire mitigation plans and procedures. Evaluating the reliability for these human actions supports the Fire PRA Model for calculating such metrics as CDF, CCDP, LERF, and CLERP for fire-induced initiating events. The initial quantification  of these metrics makes use of screening probabilities for human failure events (HFEs) where appropriate. As necessary, more detailed best estimate analyses of some human actions will be needed to obtain more realistic assessments of fire risk.
