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.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

The initial tritium supply for starting up FDS-II was done by using the Tritium Analysis Software (TAS) developed by FDS Team. The results showed that the initial tritium supply for startup was strongly dependent on the tritium burn-up fraction in plasma and mean residence time of tritium in the plasma exhaust processing system. Considering the sensitive analysis and other advanced designs, the tritium burn-up fraction in plasma was selected to be 0.1 for FDS-II. The minimum initial tritium supply for startup was ~4.2kg. Considering the potential malfunction in the fuel cycle system and assuming the reactor ran continuously before solving the malfunction, it was reasonable to keep the initial tritium supply for FDS-II as ~8.9kg.
