The Ohio State University Inherently Safe Reactor (OSU-ISR) is conceptual design for a 340 MWe (1000 MWt), natural circulation, indirect cycle, small boiling water reactor. The design features a multicavity prestressed concrete reactor vessel (PCRV) which contains all primary loop components: reactor, condenser/evaporator (C/E), subcooler/preheater (S/P) and steam separator. The goal of the dissertation research is the refinement of the OSU-ISR concept. The scope of work includes: (a) the development of simulator for the whole OSU-ISR system, and (b) the analysis of the dynamic behavior of the OSU-ISR under normal and several accident conditions towards systems design improvement. To accomplish the first task, a simulator has been developed using the DSNP (Dynamic Simulator for Nuclear Power-plant) which is a block oriented simulation language. Using this simulator, the second part of study quantifies some design and operation parameters for the OSU-ISR.
