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.

Digital control system installed at China’s Linglong One
Earlier this month, the first digital control system was put in place at Linglong One, a small modular reactor demonstration project being built at the Changjiang nuclear power plant in Hainan Province. This is the world’s first land-based commercial SMR and is controlled by China National Nuclear Power Co. Ltd., a subsidiary of the China National Nuclear Corporation (CNNC).

Carbon based material and tungsten are used in ITER as plasma facing materials in the divertor region. Presumably, carbon-tungsten mixed materials will be formed on the surface of the inner components of the vacuum vessel. Therefore, it is necessary to understand incorporation phenomena of hydrogen into carbon-tungsten mixed materials. In this study, carbon-tungsten co-deposition layers were formed by sputtering method using hydrogen RF plasma. Hydrogen incorporation was investigated as a function of atomic ratio of carbon and tungsten contained in the layer. The obtained hydrogen retention was in the range between 0.16 and 0.83 as H/(C+W). The carbon ratio dependence on hydrogen incorporation was not observed. It was found that the release behavior of the incorporated hydrogen changes depending on the atomic ratio of C and W in the layer.
