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.

PG&E to dredge Diablo Canyon intake system
The owners of the Diablo Canyon nuclear power plant plan to dredge a massive buildup of shoaled sediment from its seawater intake cove.
Pacific Gas and Electric spokesperson Suzanne Hosn said, “The dredging project in the Diablo Canyon marina will remove approximately 70,000 cubic yards of sediment to prevent circumstances that could impact the power plant’s cooling system. Dredging will take place for the first time since operations began because of a rapid increase in sediment.”

The Large Helical Device (LHD) is the largest super-conducting heliotron type device with two continuous helical winding coils. The first plasma shot in the LHD was carried out in March, 1998, and since then, plasma confinement experiments have been performed. As a future plan, a DD plasma experiment, which is an experiment with deuterium (D) beam injection into D plasma, has been proposed by researchers. Conducting such an experiment is essential for the progress in magnetic fusion research. In DD plasma experiments, tritium and neutrons are generated as a result of nuclear fusion reaction. The maximum annual amount of tritium is about 370 GBq. We are planning to remove tritium with an efficiency greater than 99 %. We conducted a tritium safety analysis and found that for inhabitants around the LHD facility, the annual dose of exposure to tritium is less than 1x10−7 mSv, which is a result of off gases and effluent liquid being released into the environment. However, to perform DD experiments, we need to obtain public consent, which is not easy. The National Research Institute for Fusion Science (NIFS) is open to the public, and we at the NIFS make every effort to communicate to the public and the municipal governments information on radiation safety. The present report shows results of preliminary safety analysis and problems with obtaining public consent to future experiments of the LHD.
