Description
The High-Temperature Gas-cooled Reactor (HTGR) has been receiving significant attention due to inherent safety and appropriately high temperature heat supply for hydrogen production. These attractive features of the HTGR can be achieved using Tri-isotopic coated fuel particles (TRISO particles). The Prismatic Modular Reactor (PMR) employs hexagonal fuel elements that contain the TRISO particles randomly distributed within the cylindrical fuel compacts. Due to the manufacturing process, the uncertainty factors of the TRISO particles, such as the fuel radius, and fuel density, are generated. In this study, the criticality biases caused by the uncertainty factors of the TRISO particles were evaluated with MCNP5 Monte Carlo code for MHTGR-350 prismatic reactor
