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.

Max Planck’s ELISE reaches record values for ITER plasma heating
The Max Planck Institute for Plasma Physics (IPP) announced that it recently has achieved a new record for ion current density for neutral particle heating at its ELISE (Extraction from a Large Ion Source Experiment) experimental testing facility in Garching, Germany. ELISE is being used to test neutral beam injection (NBI) systems that will be used to heat the plasma of the ITER fusion experiment in France.

In vivo measurements are usually carried out under the hypothesis of a known activity distribution inside the body. The measurements and the interpretation of in vivo measurements performed with the minimum hypothesis about the activity distribution are presented and discussed. Measurements have been performed with a devoted four-germanium-detector system on a male subject presenting a 30-yr-old wound contamination by americium and plutonium isotopes. The measurements have been processed after the construction of voxelized phantoms of the measured body parts and Monte Carlo (MC) calculations of organ- and detector-specific counting efficiencies. The phantom construction and MC calculations were assisted by the OEDIPE software, and the reliability of the modeling has been controlled by a comparison of the measured and simulated efficiencies for point-source measurements and for the measurement of a Spitz anthropomorphic knee phantom. Mainly based on measurements at the knee level, the 241Am specific bone activity was (0.27 ± 23%) Bq/g. Using measurements at the thorax level, no activity could be detected in the lungs; the liver activity was between 410 and 460 Bq. The activity of the axillary, thoracic airways and trunk lymph nodes depends on the retained hypothesis, but a reasonable assessment for the axillary lymph nodes is between 100 and 350 Bq.
