A repurposed parking lot at Atomic Energy of Canada Limited’s (AECL’s) Chalk River campus has been selected as the site for construction of a demonstration Micro-Modular Reactor (MMR), according to a joint statement by AECL, Canadian Nuclear Laboratories (CNL) and Global First Power (GFP).

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.

US-based Ultra Safe Nuclear Corporation has established a new facility in Salt Lake City to support the development of the company’s proprietary fully ceramic micro-encapsulated (FCM) fuel.

Materials developed at the new facility will be used in the company’s micro-modular reactor (MMR) and other nuclear reactors, including gas-cooled reactors, light water reactors, Candu reactors, and molten salt cooled reactors.

Salt Lake City was selected partly because the region is home to significant ceramics and materials expertise, central to the manufacturing of FCM fuel. The Salt Lake City Lab augments Ultra Safe’s materials development efforts at the University of Tennessee Knoxville and collaborations with the Chalk River Laboratories.

FCM is a next-generation Triso particle fuel design, replacing the 50-year-old graphite matrix of traditional Triso fuel with silicon carbide (SiC), a material used in tank armour that is extremely resistant to radiation and thermal damage. Triso, a shortened form of the term tristructural-isotropic, refers to a specific design of uranium nuclear reactor fuel.

A new use of neutron detectors for reactor monitoring and safeguards, developed by Canadian Nuclear Laboratories Ltd (CNL), could potentially be used for the independent verification of nuclear reactor activities and for monitoring the sealed cores of some small modular reactors (SMRs).
