U.S. reactor technologies to be featured at IAEA conference
A virtual side event at the 64th General Conference of the International Atomic Energy Agency will spotlight U.S. reactor technologies. The free event, US Reactor Technologies: Flexible Energy Security for Real-World Challenges, will be held this Thursday, September 24, from 9:00 a.m. to 10:30 a.m. (EDT).
The event will highlight the capabilities of small modular reactors and other innovative reactors for addressing countries’ current needs. It will also examine anticipated challenges in the future, as well as underscore the need to act now.
The event is sponsored by the U.S. Department of Energy’s Office of Nuclear Energy. Advanced registration is required.

The fuel cycle (FC) model FC-FNS is used for the calculation of hydrogen isotope flows in the fuel systems of the DEMO-FNS fusion neutron source (FNS) based on a tokamak with parameters R/a = 3.2 m/1 m, B = 5 T, Ipl = 4 to 5 MA, PNBI = 30 MW, РECR = 6 MW, and deuterium-tritium fusion power Pf = 40 MW. The FC-FNS model includes joint simulation of the gas, solid-state, and plasma flows of the fuel mixtures in the areas of the core and near-wall plasma when neon admixture is injected into the divertors. The basic principles of particle balance formation in the plasma and FC systems are described in the paper. In the process of fueling mode optimization, the requirements for productivity of the key FC systems containing the largest amount of T have been formulated. The FC configuration with the minimum tritium reserve (<2 kg) and the shortest processing time is selected.
