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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

National awards presented at ANS Winter Conference
One of the few constants at American Nuclear Society national meetings is the recognition of exceptional individuals in the nuclear community. ANS President Lisa Marshall has named this season’s award recipients, who received recognition at this week's Winter Conference and Expo in Orlando, Fla.
ANS also announced the winners of awards presented by the Society’s professional divisions. These awards have been mailed to the recipients, and the divisions have recognized or will recognize honorees at various division functions and meetings this fall. The 19 professional divisions of ANS are constituent units and represent a vast array of nuclear science and technology disciplines.

Boiling-induced natural-circulation flow in various engineered cooling channels is modeled and solved by considering the conservation of mass, momentum, and energy in the two-phase mixture, along with the two-phase friction drop and void fraction. The model is applied to estimate the induced mass flow rates through a uniform annular gap and a nonuniform annular gap between the reactor vessel and insulation under the in-vessel corium retention-external reactor vessel cooling conditions, and in the engineered corium cooling system of an ex-vessel core catcher during a severe accident. Dependence of the induced flow rate on various system parameters including the channel gap size, inlet diameter, inlet subcooling, and wall heat flux has been identified numerically. Results of the present study provide useful information for enhancing the design of engineered cooling channels to assure long-term cooling and retention of corium under severe accident conditions.
