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).

Large amounts of tritium would be handled in D-T fusion power plants. Tritium is the radioisotope of protium, and is easily taken into the human body. With regard to nuclear fusion reactor facilities, the concept of multi-confinement system is applied to prevent tritium leaking to the environment. The last barrier to confine tritium is a building itself containing all equipment and facilities. If a severe accident takes place, tritium gas could leak into the facilities. In order to prevent tritium leaking to the environment, a secure air cleanup system (ACS) needs to be installed in the building. In ACS, the tritium gas, which leaks to rooms by an accident, is oxidized by catalysts, and then tritiated water vapor is collected by adsorbents. This method can remove tritium effectively, whereas which has a problem related to large ventilation force required to overcome high pressure drop in catalyst and adsorbent beds. Ventilation force could be substantially reduced by applying honeycomb catalysts and adsorbents to ACS. We investigated applicability of honeycomb catalysts and adsorbents to ACS, performing a screening test for the performance of honeycomb catalysts and adsorbents.
