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.

Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

Analysis of process data from initial detritiation tests in a pilot-scale Combined Electrolysis and Catalytic Exchange (CECE) Facility1 indicated that very high detritiation factors (DFs), at least 10 000, could be achieved in the facility. Performance requirements for process equipment were evaluated and some minor refinements were made to selected components. In particular, the recombination efficiency of tritium in the electrolytic oxygen stream was improved and the tritiated-water feed point was moved to a location lower in the catalyst column. With these modifications, the facility was able to remove more than 99.998% of the tritium (i.e., achieve a DF greater than 50 000) from a heavy water feed stream containing 330 GBq/kg, with 7.8 TBq/kg in the electrolysis cell. The processing rate at these conditions was about 2.2 Mg/a, compared with a rate of 5 Mg/a for a DF of 180.
