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.

High-purity beryllium in the form of spherical pebbles of size ranging from 0.2 to 2 mm are required for neutron multiplication in the test blanket module of the helium-cooled solid breeder in ITER. The pebbles should be dense and have stringent chemical composition to withstand a high-temperature and irradiation environment. Hence, the conventional method of preparing beryllium pebbles has to be modified to a novel technique such as the rotating electrode process (REP). In the present paper REP modeling, design, and selection of process parameters to control the particle size have been carried out. Based on the results on the preparation of surrogate stainless steel spherical pebbles, beryllium pebbles have been prepared by REP, and the results obtained are presented. The important parameters that affect the pebble size and production rate are found to be anode diameter, material constants, revolutions per minute, arc gap, and the cooling cover gas in the REP chamber. The pebbles once formed are kept in levitated condition in the chamber for achieving near-perfect spherical shape. This paper also focuses on beryllium pebble handling with respect to safety and industrial hygiene control as per the prescribed international standard.
