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
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

The reactivity transient following a control rod step strongly depends on quantities that determine the thermal reactivity feedback. For the special case of a pressurized water reactor, these quantities are the reactivity temperature coefficients and the heat transfer between fuel and coolant. Therefore, it is possible to determine these quantities by fitting appropriate model calculations to measured reactivity transients. This so-called “rod step method” was extensively applied for the first time in the first cycle of the nuclear power plant KCB at Borssele in the Netherlands. The values of the heat transfer between fuel and coolant and those of the fuel temperature coefficient that are obtained by this method agree well with the theoretically expected behavior with increasing core burnup.
