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
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.

Candidates for leadership provide statements: ANS Board of Directors
With the annual ANS election right around the corner, American Nuclear Society members will be going to the polls to vote for a vice president/president-elect, treasurer, and members-at-large for the Board of Directors. In January, Nuclear News published statements from candidates for vice president/president-elect and treasurer. This month, we are featuring statements from each nominee for the Board of Directors.

Transient tests were conducted on nonirradiated oxide pellet-containing fuel pins at SPERT to investigate the possible effects of large single 550-μm diam PuO2 particles on transient behavior. Results show that the effect of the large PuO2 particles was to reduce slightly the cladding failure threshold energy from the range of 225 to 274 cal/g of fuel to the range of 200 to 213 cal/g of fuel. Clad perforation occurs by localized melting caused by the expulsion of PuO2 particles through the cladding. The presence of single 550-μm diam PuO2 particles in mixed-oxide fuels does not appear to affect significantly the cladding failure threshold energy from that of mixed-oxide fuels with the normal PuO2 particle size and distribution. Therefore, product specifications which limit the maximum PuO2 particle size to 550-μm diam in mixed-oxide fuels do not appear warranted from the standpoint of transient fuel performance considerations.
