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.

DTE Energy studying uprate at Fermi-2, considers Fermi-3’s prospects
DTE Energy, the owner of Fermi nuclear power plant in Michigan, is considering an extended uprate for Unit 2 that would increase its 1,100-MW generation capacity by 150 MW.

A rod drive using a stepping motor has been developed for the Argonne Advanced Research Reactor critical experiment. The control rod is suspended from a roller chain which meshes with a sprocket driven by the motor. Rod position is indicated by counting the number of steps. Scram is produced by interrupting the power to the motor windings, thus removing the motor's holding torque. This design offers significant reductions in size and cost compared to existing types.
