Preliminary Risk Assessment of a Generalized Molten Salt Reactor Off-Gas System

摘要

Recently in the nuclear industry there has been increasing interest in molten salt reactors (MSRs). There are at least six national efforts currently developing MSR designs [1]. In the US, the Department of Energy's Office of Nuclear Energy (DOE-NE) is engaging the MSR sector of the advanced nuclear reactor development effort via its GAIN (Gateway for Accelerated Innovation in Nuclear) program and one of DOE-NE's Advanced Reactor Concept awards to support development of the Molten Chloride Fast Reactor (MCFR) [2]. To achieve the enhanced safety goals for advanced reactors, such as those described by the US Nuclear Regulatory Commission (NRC) [3], it is desirable to develop and use an incremental risk assessment approach that supports the incorporation of safety into the design from the earliest stages of development [4].
