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.

IEA report: Challenges need to be resolved to support global nuclear energy growth
The International Energy Agency published a new report this month outlining how continued innovation, government support, and new business models can unleash nuclear power expansion worldwide.
The Path to a New Era for Nuclear Energy report “reviews the status of nuclear energy around the world and explores risks related to policies, construction, and financing.”

Quasi-infinite medium neutron spectra have been measured as a function of moderator temperature and poison concentrations in water. Three different poisons were used: a l/υ absorber (boron), and the resonance absorbers erbium and gadolinium. These measurements were performed utilizing the General Atomic Linac and standard time-of-flight techniques. The temperature range covered was from ambient to about 300°C. The measurements were compared to the latest theoretical models using the best known calculational techniques available. The scattering kernel based on the modified Haywood frequency spectra and computed by the GASKET-FLANGE computer codes appears to give the best agreement with the experimental data.
