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.
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.

NRC schedules webinars on Holtec’s proposed New Mexico storage site
The Nuclear Regulatory Commission has scheduled four webinars in late August and early September to present its draft environmental findings and receive comments on Holtec International’s proposed consolidated spent nuclear fuel storage facility in New Mexico. Webinars were previously held on June 23 and July 9.
As published in the August 13 Federal Register, the public comment webinars will be held on August 20 from 6–9 p.m., August 25 from 2–5 p.m., August 26 from 6–9 p.m., and September 2 from 11 a.m.–2 p.m. All times are Eastern. Information for the webinars is posted on the NRC’s Public Meetings webpage.

To investigate core plasma heating in fast ignition, a relativistic Fokker-Planck code for fast electrons is developed in a one-dimensional planar coordinates system. It is found that in dense plasmas, the Joule heating is much smaller than the heating through Coulomb interactions. In the latter energy deposition process, the long-range collective effect is comparable to that of binary electron-electron collisions. Moreover, on the basis of coupled transport-hydrodynamic simulations in one-dimensional planar geometry, the core heating process for an ignition-experiment-grade compressed core (R = 0.3 g/cm2) is examined, and a possibility of evaluation of burn history from the neutron spectrum is shown. It is shown that a relatively low energy component (E0 1 MeV) of electron beams plays an important role for effective core heating in fast ignition.
