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.

Aerosol revaporization in piping is being investigated in the WIND project at the Japan Atomic Energy Research Institute. The objectives of this study are to characterize the aerosol revaporization from piping surfaces under various thermal-hydraulic conditions and to obtain insights applicable to the validation of analytical models. Cesium iodide aerosol was introduced into the test section with a carrier gas. After quantifying the deposited mass of cesium and iodine, the test section was reheated to realize the revaporization. The revaporized materials were deposited onto another test section with an axial temperature gradient located downstream. Two runs (WAV1 and WAV2) were conducted. In WAV2, the influence of metaboric acid was examined. Most of the deposited cesium and iodine in the test section was revaporized and transported downstream. In WAV2, deposition density of cesium was much larger than that of iodine. It was supposed that a part of the cesium iodide that was deposited in the upstream test section reacted with boric oxide to form cesium metaborate.
