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.

Edge-localized mode (ELM) simulation experiments were held on the quasi-stationary plasma accelerator QSPA-T to study the formation of plasma-facing material (PFM) erosion products. Parameters of the deuterium plasma heat loads in QSPA-T were close to those expected during transient events in ITER. A diagnostic system for measuring the deposition rate of the erosion products with resolution time of 0.02 ms (pulse duration 0.5 ms) was designed. It allowed defining the deposition rate dependence on time and property changes of the deposited film during the pulse. The average deposition rate in QSPA-T under exposures to ultra-short D plasmas was in the range of (0.1 to 100)×1019 at·cm2·s−1, which was much higher than that for stationary processes. It has been found that deuterium concentration in the deposited W films depends on substrate temperature and deposition rate approximately in the same way as for stationary processes. As the substrate temperature and deposition rate increased, the D/W atomic ratio in the W films decreased. For describing the evolution of the D/W ratio with the substrate temperature and the tungsten deposition rate, an empirical equation proposed by De Temmerman and Doerner (J. Nucl. Mater., 2009), but with alternative parameters, has been used.
