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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

A methodology to adjust resonance parameters is developed and tested on the lowest-energy resonances of 238U, 240Pu, and 242Pu. It is shown that adjusting the basic nuclear parameters is the only consistent way to adjust infinitely dilute cross sections and to reduce the cross-section deconvolution problem. Taking into account the self-shielding effects enables us to treat different kinds of integral experiments (fast and thermal) and to achieve a statistically consistent adjustment. Also, the standard multigroup cross-section adjustment in the epithermal region can be interpreted as an indication of the required correction of an average reaction rate.
