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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

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.
