A new publication in the IAEA’s Technical Report Series, Status of Molten Salt Reactor Technology, outlines the current status of molten salt reactor (MSR) technology around the world. It reviews the history of MSRs and takes a look at the current research and development activities taking place. The advantages of this technology, including a smaller high level waste footprint and passive safety features, as well as some of the technical challenges, such as developing components capable of operating in very high temperature environments, are detailed.

USNC has said it hopes to build and operate its first micro modular reactor unit by 2026. Courtesy USNC/NRG. Netherlands-based NRG is to carry out a programme of irradiation tests on Ultra Safe Nuclear Corporation’s (USNC) proprietary fully ceramic microencapsulated (FCM) fuel at the high flux reactor in Petten.

NRG said the aim of the tests is to demonstrate the safety of the fuel for the 20-year lifespan of Seattle-based USNC’s micro modular reactor. NRG said extensive pre- and post-irradiation tests at its hot cell laboratories will be part of the programme.

FCM fuel is a next-generation tristructural-Isotropic (Triso) particle fuel design, replacing the 50-year-old graphite matrix of traditional Triso fuel with silicon carbide, a material that is extremely resistant to radiation and thermal damage.

The SiC matrix in FCM fuel provides a dense, gas-tight barrier, preventing the escape of fission products even if a Triso particle should rupture during operation. The result is a safer nuclear fuel that can withstand higher temperatures and more radiation.

Nuclear Research & Consultancy Group (NRG) of the Netherlands will conduct a programme of irradiation tests on Ultra Safe Nuclear Corporation's (USNC's) proprietary Fully Ceramic Microencapsulated (FCM) fuel at the High Flux Reactor (HFR) in Petten. The aim of the tests is to demonstrate the safety of the fuel for the 20-year lifespan of the USNC's Micro Modular Reactor.

Pickering is one of three nuclear power stations owned by OPG. The company has a total of 18 Candu reactors. Ontario Power Generation’s Centre for Canadian Nuclear Sustainability (CCNS) has joined forces with Moltex Energy on a project aimed at recycling used fuel from Candu reactors.

CCNS will provide CAD1m (€680,000) in funding to help Canada-based Moltex demonstrate the technical viability of a new process to recycle used Candu fuel.

When removed from an operating reactor, used Candu fuel still contains energy in the form of fissionable uranium and plutonium isotopes, which cannot be used without removing fission products. Moltex’s process would recover these energy resources and prepare them for use as new fuel in other advanced reactor designs, potentially reducing the volume of the material requiring long-term storage in a deep geological repository.

Ultra Safe Nuclear Corporation (USNC) has established a new facility in Salt Lake City, Utah, to support the development of its proprietary Fully Ceramic Microencapsulated (FCM) fuel. Materials developed there will be used in USNC's Micro Modular Reactor (MMR) and other nuclear reactors, including gas-cooled reactors, light water reactors, CANDU reactors and molten salt cooled reactors.

The US is buying 32t of Iranian heavy water to help Iran meet the terms of last July's landmark nuclear deal under which Iran agreed to curb its nuclear programme in exchange for sanctions relief. The agreement was signed on 22 April in Vienna between Iran and officials from the six countries that negotiated the nuclear deal - E3/EU+3 (China, France, Germany, Russia, the UK and the USA plus the European Union). It calls for the US Department of Energy's (DOE's) Isotope Program to purchase the heavy water from a subsidiary of the Atomic Energy Organization of Iran (AEOI) for about $8.6m, officials said. They said the heavy water will be stored at the Oak Ridge National Laboratory (ORNL) in Tennessee and then resold on the commercial market for research purposes.
