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.

House Dems introduce clean energy bill for net zero
Democratic leaders in the House last week introduced the Climate Leadership and Environmental Action for our Nation’s Future Act (the CLEAN Future Act, or H.R. 1512), a nearly 1,000-page piece of climate change–focused legislation establishing, among other things, a federal clean electricity standard that targets a 50 percent reduction in greenhouse gas emissions from 2005 levels by 2030 and net-zero emissions by 2050.
The bill, a draft version of which was released in January 2020, presents a sweeping set of policy proposals, both sector-specific and economy-wide, to meet those targets. The final version includes a number of significant revisions to bring the legislation into closer alignment with President Biden’s climate policy campaign pledges. For example, the bill’s clean electricity standard would require all retail electricity suppliers to provide 80 percent clean energy to consumers by 2030 and 100 percent by 2035. (A six-page fact sheet detailing the updates is available online.)

The numerical analysis is performed with two dimensional wave code for controlling the eigenmode formation of fast Alfvén waves in the GAMMA 10 central cell. The plasma production by fast waves depends on the wave excitation in the plasma. Eigenmodes are strongly formed when the boundary conditions in the axial and radial directions are satisfied. As the optimum density for the formation of eigenmode exists discretely, the density is clamped at the value where the eigenmode is strongly formed. For the higher density plasma production, the eigenmodes must be continuously excited as the density increases. It is found that the almost continuous excitation of eigenmodes can be realized by using two waves with different frequencies at the same time.
