Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

Taking into account Einstein’s general theory of relativity, a modification of Lockheed’s compact fusion reactor concept is proposed by replacing the two superconducting tori with rapidly rotating tori rotating in opposite directions. According to the general theory of relativity, two Coriolis force fields in opposite directions are set up, both of them having a negative mass density in their corotating reference systems, with a vanishing negative mass density in the center in between the rotating tori, where the hot fusion plasma is centered. Because of the Nernst effect going in the opposite direction, large toroidal currents are set up, repelling the hot plasma from the much cooler tori. This results in closed magnetic field lines for stable plasma confinement. The remaining problem, the removal of the heat released by neutron absorption in the metallic tori, can be resolved by a pulsed operation, axially injecting cool deuterium-tritium gas, from which the heat is externally removed by a radiator.
