![]() Different from the MFSR, the MCFR can only be designed as a MSFR due to the large neutron absorption cross section of Cl in the thermal spectrum. ![]() Unlike fluoride salt, chloride salt can also be used as carrier salt. Due to their simple structure, good breeding and transmutation performance as well as their inherent safety and security, MSFRs and MOSART were selected for further research. Afterwards, Russia designed the molten salt actinide recycler and transmuter (MOSART), intended for solving the problem of spent fuel reprocessing in the pressurized water reactor (PWR). Therefore, after investigating various core arrangements and their fuel reprocessing performance, a novel concept, namely the molten salt fast reactor (MSFR), was proposed. It was proven that the total temperature coefficient of an MSBR is slightly positive and the lifespan of the graphite moderator in its core is rather short. Since the 1990s, the National Center for Scientific Research (CNRS) has been performing research on MSRs and reassessing MSBRs. More technical issues related to MSRs, such as fuel reprocessing, nuclear proliferation concerns, and the transmutation performance, have been researched, presenting many useful conclusions. Based on the accumulated MSRE technology and operation experiences, other MFSRs, such as the denatured molten salt reactor (DMSR), molten salt breeder reactor (MSBR), and the FUJI-MSR, were proposed in succession. However, even if this concept looked promising, the MSRE was only operated for 4 years before being shut down. Research on MFSRs originates in the 1960s, during which the Oak Ridge National Laboratory (ORNL) first proposed the molten salt reactor experiment (MSRE). The corresponding reactor is the molten fluoride salt reactor (MFSR). In general, fluoride salt is used as the fuel carrier salt in MSRs. This enables the MSR to operate with less residual reactivity and greatly improves its breeding performance and neutron economy. The flow of liquid fuel allows the FPs and fissile fuel breeding in an MSR to be extracted on-line without requiring a shutdown. It is characterized by its inherent safety, simple structure, no need to fabricate fuel assemblies, and low residual reactivity. In the end, a reprocessing method suitable for MCFRs was determined through calculation and analysis, which provides a reference for the further research of MCFRs.Īs the only liquid fuel reactor retained by the GEN-IV, the MSR employs molten salt as both coolant and fuel. Furthermore, the characteristics of the different reprocessing modes and MCFR rates were analyzed in terms of safety, radioactivity level, neutron economy, and breeding capacity. As such, this study investigated the effect of different isotopes, especially FPs, on the neutronic performance of an MCFR, such as its breeding performance. ![]() However, as the most important feature for MSRs, the effect of different reprocessing modes on MCFRs must be researched in depth. ![]() Thus, MCFRs have been recognized as a type of MSR with great prospects for future development. Compared to molten fluoride salt reactors (MFSRs), MCFRs have a higher solubility of heavy metal atoms, a harder neutron spectrum, lower accumulation of fission products (FPs), and better breeding and transmutation performance. Molten chloride salt fast reactors (MCFRs) are a type of MSR.
