The Development of Trip Coverage Maps for the McMaster Nuclear Reactor

Abstract

PARET/ANL is a coupled point-kinetic and thermalhydraulic code with reactivity feedback modeling capability. A conservative PARET/ANL model of the McMaster Nuclear Reactor (MNR) has been developed by considering the characteristics and operating limits of the MNR core. A conservative modeling approach assesses MNR safety system coverage in the context of reactivity initiated accidents (RIAs) previously studied in the Safety Analysis Report. The PARET/ANL modeling provides power and temperature vs. time results from which trip coverage maps have been generated for each accident category. Modeling limitations are discussed in the context of both MNR operating and safety limits.
