Performing research and testing to qualify the TRISO LEU fuel for GEN-IV reactors in the US. Exploring the use of proliferation-resistant fuels in the US, including thorium-based and other advanced fuel cycle concepts. Performing basic and applied research using the enhanced capabilities offered by a "Generation IV" type nuclear reactor system.
The majority of reactors in operation around the world are considered second generation and third generation reactor systems, as the majority of the first generation systems have been retired. China was the first country to operate a demonstration generation-IV reactor, the HTR-PM in Shidaowan, Shandong , [ 7 ] [ 8 ] which is a pebble-bed type ...
Classed as a Generation IV reactor, it features a fast-neutron spectrum and closed fuel cycle for efficient conversion of fertile uranium and management of actinides. The reference reactor design is a helium - cooled system operating with an outlet temperature of 850 °C (1,560 °F) using a direct Brayton closed-cycle gas turbine for high ...
In October 2010, the South Texas Project announced that the Tokyo Electric Power Company (TEPCO) had entered into an agreement with Nuclear Innovation North America (a joint venture between the reactor manufacturer, Toshiba, and plant partner NRG Energy) which was the largest of the two stakeholders in the proposed reactors, to purchase an ...
As of November 2013, expansion had been suspended due a natural gas boom dramatically lowering power prices in Texas, and Mitsubishi Heavy Industries suspending development of its reactor design to focus on restarting its reactors in Japan. The Texas power generation company did not withdraw its application to the NRC entirely, leaving open the ...
Exactly how much highly enriched uranium the US has is a classified secret, and there are a lot of interests competing for it, from national security to research nuclear reactors.
Sketch of a pebble-bed reactor. The pebble-bed reactor (PBR) is a design for a graphite-moderated, gas-cooled nuclear reactor. It is a type of very-high-temperature reactor (VHTR), one of the six classes of nuclear reactors in the Generation IV initiative. Graphite pebble for reactor. The basic design features spherical fuel elements called ...
Oregon-based NuScale became the first company to get approval from the Nuclear Regulatory Commission to build SMRs in 2022, but the company canceled plans to deploy six reactors in Idaho last year ...
