MELCOR Modeling of Non-LWR Systems Draft Report for the Nuclear Regulatory Commission
This report provides an overview of technical issues and design features relevant to advanced reactors and reviews MELCOR's current readiness for modeling accidents in such reactor types. This report describes advanced reactor physics models currently available or under development, and gauges the level of effort required to develop new models and capabilities applicable to assessing advanced reactor safety issues. Finally, this report reviews the available database that can be used in verification and validation of new models. Four general advanced reactor types are considered in this report: 1) High Temperature Gas-Cooled Reactor (HTGR) 2) Sodium Fast Reactor (SFR) 3) Molten Salt Reactor (MSR) 4) Fluoride Salt-Cooled High Temperature Reactor (FHR)
