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.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

A method is developed for estimating, on a generic basis, the probability per year for an atom of average rock at a given depth to be transferred into a river. For a 600-m depth, it is 0.9 × 10−9/yr. The transfer probability from shallow aquifers or rivers into human stomachs is dominated by our use of well water with additional contributions from direct use of river water, irrigation, and fish; the total probability is 4 × 10−4. The product of these, corrected for the greater leach-ability of waste glass than of average rock, gives a total transfer rate for an atom of buried waste into human stomachs of 10−12/yr. When combined with health risk information, it is concluded that we may eventually expect 0.017 deaths/GW(electric).yr from high-level waste, and 0.068 deaths/GW(electric) .yr from unreprocessed spent fuel.
