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.

Fukiushima Daiichi: 10 years on

It was a rather normal day back on March 11, 2011, at the Fukushima Daiichi nuclear plant before 2:45 p.m. That was the time when the Great Tohoku Earthquake struck, followed by a massive tsunami that caused three reactor meltdowns and forever changed the nuclear power industry in Japan and worldwide. Now, 10 years later, much has been learned and done to improve nuclear safety, and despite many challenges, significant progress is being made to decontaminate and defuel the extensively damaged Fukushima Daiichi reactor site. This is a summary of what happened, progress to date, current situation, and the outlook for the future there.

A test facility for a full-scale prototype of the Neutral Beam Injector (NBI) for ITER is planned to be built in Padova, Italy, in the framework of the European activities in support of ITER. Two possible sites were considered: the site hosting RFX (Reversed Field eXperiment), connected to the 400-kV transmission network, and the site hosting the National Institute for Nuclear Physics (INFN), connected to the 132-kV network. Analyses have been made to evaluate the impact on the two HV networks due to the additional NBI load. A particular aspect was studied in detail: during the NBI operation, very frequent accelerator grids breakdowns are expected, requiring fast de-energization of the main power supplies, followed by voltage re-application in about 50 ms; this can cause active and reactive power steps and consequent voltage fluctuations (flickers) on the HV networks. The analyses are described in the paper and the main results reported and discussed.
