ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Direct waste transfer process quickens at Savannah River Site
The Department of Energy Office of Environmental Management’s liquid waste contractor at the Savannah River Site this month marked the first direct transfer of decontaminated waste from the Salt Waste Processing Facility (SWPF) to the Saltstone Production Facility (SPF). This is a new step in optimizing waste processing, according to the DOE.

The availability of Tritium is a problem for the Deuterium-Tritium (D-T) fusion reactors since the element does not exist in nature and has to be bred from Li-6 through neuron capture. The goal of this paper is to explore a possibility of operating a symbiotic system consisting of fleets of fission reactors coupled with fusion reactors. It is proposed in this paper to use salt with high Li-6 content in Fluoride salt-cooled High-temperature Reactor (FHRs) to produce tritium as fuel for D-T fusion reactors. Tritium breeding blankets will therefore no longer be required, potentially making fusion reactors simpler and cheaper to construct and maintain. Two FHR designs, i.e. pebble bed and prismatic block, are studied in this work to investigate the feasibility of the proposed Fission-Fusion hybrid systems. An investigation into neutronics, tritium production, and potential safety issues in the proposed FHR designs are carried out. The tradeoffs between fission reactor performance, such as achievable burnup and fresh fuel enrichment, and tritium production rate are also discussed. Results have shown that such hybrid systems are attractive and potentially feasible. The maximum tritium production rate of the selected design options can reach up to approximately 4 kg per GW thermal power per year.
