Accident Management for a Loss of Feedwater in a Pressurized Water Reactor

A pressurized water reactor plant scenario is evaluated during a loss of feedwater following multiple failures and operator interventions. For a more realistic analysis, an experiment performed on the SPES facility is taken as a reference. A suitably qualified RELAP5/MOD2 code nodalization was used to evaluate the behavior of the facility under the failure of various systems and the activation of typical accident management recovery procedures.
