The Integral Molten Salt Reactor and the Benefits of Having a Liquid Fission Reactor

By Hackaday

Although to most the term ‘fission reactor’ brings to mind something close to the commonly operated light-water reactors (LWRs) which operate using plain water (H2O) as coolant and with sluggish, thermal neutrons, there are a dizzying number of other designs possible. Some of these have been in use for decades, like Canada’s heavy water (D2O) reactors (CANDU), while others are only now beginning to take their first step towards commercialization.

Fourth Generation Nuclear Reactors Take A Big Step Forward

By Forbes

Last week Terrestrial Energy announced that it has achieved a major regulatory milestone with the completion of Phase 2 of the pre-licensing Vendor Design Review (VDR) for its IMSR power plant. The VDR is a comprehensive review of the IMSR design conducted by the Canadian Nuclear Safety Commission (CNSC), and its completion is a significant step forward in the commercial development of the IMSR.

Terrestrial Energy’s molten salt reactor passes key review

By Energy Monitor

Canadian nuclear energy company Terrestrial Energy has made a breakthrough in the commercial development of its Integral Molten Salt Reactor (IMSR) power plant, after the Canadian Nuclear Safety Commission (CNSC) completed Phase 2 of the pre-licensing Vendor Design Review (VDR). The development marks the first advanced, high-temperature fission technology to complete a review of this type, bringing the small modular reactor (SMR) tantalisingly close to market.

The coal-to-nuclear conversion: Are Gen IV reactors the answer?

By Nuclear Newswire

In the ongoing quest to mitigate the effects of climate change, new technology can create new solutions. Even today, however, coal is still a main source of power around the globe, often out of necessity. Many coal-burning plants have already been converted for gas or biomass, but these measures alone are not nearly enough to meet net-zero carbon goals. There is a better solution, however: repowering coal plants with nuclear technology—specifically, Generation IV reactors.
