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.

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 absolute gamma dose was measured at 60 locations within the Tungsten Water-Moderated Reactor critical assembly. The neutron dose was measured at 30 locations. Graphite wall thimble ionization chambers filled with carbon dioxide were used for gamma measurements and polyethylene wall chambers filled with ethylene were used for mixed gamma and neutron fluxes. The chambers were absolutely calibrated in a bremsstrahlung beam against a secondary calibration standard and in a reactor against a water-filled calorimeter. These calibrations were used to determine the absolute gamma and neutron responses for the chambers; this permitted partitioning the measured mixed radiation dose into a neutron dose. The measured gamma doses were compared with an ATHENA Monte Carlo calculation. Good agreement was found for the 16 locations compared. The average deviation was 10%. In addition, the measured neutron doses were compared with a first-collision calculation of the dose. The calculated neutron doses were uniformly low with an average deviation from the measurement of 18%.
