Scoping systems analysis of a 350 MWt modular liquid metal cooled reactor

PDF Version Also Available for Download.

Description

The systems analysis code SASSYS was used to explore the sensitivity of the system response to various inherent reactivity feedback mechanisms and design features for a small, liquid-metal-cooled reactor during the first 1000 s following the initiation of an unprotected loss-of-flow and/or loss-of-primary-heat-removal transient. The results show that to maximize the inherent safety of small, liquid-metal-cooled reactors, inherent feedback mechanisms should be accounted for in establishing design features such as the flow coastdown time constant and the control rod suspension system. The results also indicate insensitivity of the system response to the operation or non-operation of heat removal systems during ... continued below

The results also indicate insensitivity of the system response to the operation or non-operation of heat removal systems during the early part of an unprotected loss-of-flow transient.
