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.
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.

U.S. reactor technologies to be featured at IAEA conference
A virtual side event at the 64th General Conference of the International Atomic Energy Agency will spotlight U.S. reactor technologies. The free event, US Reactor Technologies: Flexible Energy Security for Real-World Challenges, will be held this Thursday, September 24, from 9:00 a.m. to 10:30 a.m. (EDT).
The event will highlight the capabilities of small modular reactors and other innovative reactors for addressing countries’ current needs. It will also examine anticipated challenges in the future, as well as underscore the need to act now.
The event is sponsored by the U.S. Department of Energy’s Office of Nuclear Energy. Advanced registration is required.

A series of discussions on tritiated water of the Fukushima Daiichi Nuclear Power Station (FD-NPS) was carried out. A large amount of contaminated water has been generated in FD-NPS. Radioisotopes in the contaminated water have been removed except tritium, and thus, tritiated water has been left and stored. As of March 2019, 1 126 500 m3 of tritiated water has been stored in tanks. The average tritium concentration in the tritiated water is 1000 Bq/cm3.
Various options for handling the tritiated water, such as discharge into the sea, geosphere injection, underground burial, and vapor or hydrogen release with and without pretreatment, were discussed on the basis that there is no scientific impact on people. Through the discussions, 11 options for handling tritiated water were summarized. At the same time, some experimental tests of tritium separation (with small-scale and/or full-scale component test stands) were also carried out. As a result, it was concluded that the tested separation technologies could not yet be applied to the case of FD-NPS. No selection from the 11 options has yet been recommended, and further discussions for the tritiated water have continued with public hearings.
