US-based X-energy announced on 9 August that it will expand its fuel division as a wholly owned subsidiary called TRISO-X to commercially develop its proprietary tristructural isotropic (TRISO) fuel for the burgeoning advanced nuclear energy sector. Dr Pete Pappano, X-energy’s Vice President of fuel production, will lead the new company as its President. Since joining X-energy in 2015, Dr Pappano has been instrumental in supporting the company’s ability to produce advanced nuclear fuel at a commercial scale. As the leader of X-energy’s ARC15 project, a five-year programme funded by the Department of Energy, he established a commercial-scale fuel line at Oak Ridge National Laboratory, which has demonstrated the company’s patented TRISO fabrication process leading to higher yields and higher quality fuel.

The US Department of Energy’s (DOE’s) Oak Ridge National Laboratory ORNL said on 3 August that it is to examine Westinghouse Accident Tolerant Fuel (ATF). ORNL recently received several nuclear fuel test rods that were irradiated in a commercial reactor. The new advanced fuel concept is being developed by Westinghouse through DOE’s ATF programme. The industry-led effort is looking to commercialise new fuels within the decade to help improve the performance and economics of US reactors. ORNL will examine the irradiated fuel rods over the next year to support licensing efforts with the Nuclear Regulatory Commission (NRC).

Irradiated lead test rods containing Westinghouse's EnCore advanced fuel technology have arrived at the US Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) where they will undergo a year of testing to support regulatory licensing efforts. The fuel is being developed under the DOE's Accident Tolerant Fuel Program, an industry-led effort looking to commercialise new fuels within the decade.

Seattle-based Ultra Safe Nuclear Corporation (USNC) announced on 22 June that it has begun working with the Nuclear Research & Consultancy Group (NRG) from the Netherlands. NRG will implement a programme to analyse performance and safety attributes of the company’s proprietary Fully Ceramic Microencapsulated (FCMTM) fuel designed for use in its Micro Modular Reactor (MMRTM).

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.

Russia’s AA Bochvar Research Institute of Inorganic Materials (VNIINM – part of Rosatom’s Fuel Company TVEL) said on 29 April that, by the end of the year, it plans to complete the third cycle of irradiation of experimental accident tolerant fuel assemblies with VVER and PWR fuel elements comprising four different combinations of fuel and structural materials (zirconium alloy with chromium-containing coatings and chromium-nickel alloy 42??? as cladding materials, traditional uranium dioxide or alloy uranium-molybdenum as fuel). In addition, TVEL has ordered VNIINM to begin R&D work on the development of a technology for making tolerant fuel pellets from uranium disilicide (a compound of uranium and silicon - U3Si2). This aims to improve the safety of operation of domestically produced fuel, improve the technical and economic indicators of its operation, and also ensure the competitiveness of Rosatom in the world nuclear fuel market.

Canadian Nuclear Laboratories (CNL) announced on 13 April that it has fabricated Fully Ceramic Microencapsulated (FCM) fuel pellets, an advanced and proprietary reactor fuel designed by Ultra Safe Nuclear Corporation (USNC) for their Micro Modular Reactor (MMR). The project was funded through the Canadian Nuclear Research Initiative (CNRI) and marks the first time that a Tristructural-Isotropic (TRISO) based fuel has been manufactured in Canada. The CNRI programme, launched in 2019, aims to help small modular reactor (SMR) vendors gain access to CNL expertise in order to help advance the development and commercialisation of their technologies.

Canadian Nuclear Laboratories has fabricated fully ceramic microencapsulated fuel pellets, an advanced and proprietary reactor fuel designed by Ultra Safe Nuclear Corporation (USNC) for its micro modular reactor.

The project, funded through the Canadian Nuclear Research Initiative, represents the first time that a Tristructural-Isotropic (Triso)-based fuel has been manufactured in Canada.

USNC’s pellet design consists of spherical Triso particles dispersed in a matrix of silicon carbide. The Triso particles have a layered structure with a dense fuel kernel, coated with layers of graphite and silicon carbide. This makes the particles incredibly robust and able to withstand intense heat and pressure.
