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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

The consequence of the failure effect of burn control diagnostic systems, such as neutron diagnostics, bolometers, electron cyclotron emission power loss diagnostics, interferometer, and lost alpha detector, on ignited operation has been analyzed, and the fail-safe operation in a tokamak fusion reactor including the International Thermonuclear Experimental Reactor (ITER) has been considered. Because the failure of the neutron diagnostic system for fusion power measurement leads to a fusion power surge for the simple control algorithm, the fail-safe control algorithm has been introduced to avoid this problem. As failure of the power loss measurement such as the bolometer system terminates the ignition, then it is less problematic. The effect of the interferometer fringe counting error on the ignited operation is not simple, as just mentioned, and a lost alpha detector can be removed from the feedback system using the preset value.
