The integral molten salt reactor (IMSR) is a nuclear power plant design targeted at developing a commercial product for the small modular reactor (SMR) market. It employs molten salt reactor technology which is being developed by the Canadian company Terrestrial Energy .

It provides a description of IMSR® Core-unit structures, systems and components (SSC) to support meeting the information requirements in 10 CFR 52.137 related to identifying, defining, and describing the IMSR® Core-unit design basis in an SDA application for the Core-unit.

The IMSR cogeneration plant blends proven molten salt technology with innovative and patented enhancements, including the integration of primary reactor components into a sealed, replaceable vessel called the IMSR Core-unit.

2017年1月1日 · The IMSR uses molten fluoride salt, a highly stable, inert liquid with robust coolant properties and high intrinsic radionuclide retention properties, for its primary fuel salt. A secondary, coolant salt loop, also using a fluoride salt (but without fuel), transfers heat away from the primary heat exchangers integrated inside the core-unit.

• Proprietary MSR design – the Integral Molten Salt Reactor (“IMSR™”) • High technology readiness • Conducting basic/preliminary engineering work - Concludes with construction and licensing of the first commercial IMSR power plant (400 MWth reactor) • …

Heat at 700°C is generated from two thermal-spectrum, graphite-moderated, molten-fluoride-salt reactors (IMSR). These reactors use today’s standard nuclear fuel – comprising standard-assay low-enriched uranium (less than 5 percent U-235) – …

Comprehensive advanced reactor design process. ⎯ Defines the entire IMSR® technology development program. ⎯ Encompasses all research, development, analysis, engineering, licensing, and testing. ⎯ Will lead to a fully designed, engineered, and …

IMSR® is a molten salt reactor system that uses: • Fluoride chemistry • Under 5% LEU once-through fuel cycle • Thermal spectrum • Graphite moderator • Integral core architecture Conclusion: IMSR® has no fundamental technology challenges remaining

2025年3月26日 · The combined entity will apply for listing on Nasdaq under the ticker symbol “IMSR”. CHARLOTTE, N.C. and STAMFORD, Conn., March 26, 2025 (GLOBE NEWSWIRE) -- Terrestrial Energy Inc., a ...

2024年9月21日 · Terrestrial Energy的IMSR设计是单堆442 MWt (IMSR400)的小型模块化熔盐燃料、石墨慢化、热中子谱反应堆。 Terrestrial Energy已开发一种双堆配置，可提供884 MWt/390 MWe的功率。 其设计特点是反应堆容器完全密封，容器内集成了泵、热交换器和停堆棒。 密封的堆芯单元在其使用寿命 (通常为7年)结束时被完全更换。 这样就可以实现工厂生产水平的质量控制和经济性，同时避免在电站厂址打开和维修反应堆容器。 IMSR400实现了最高级别的固有安 …
