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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

We first examined two lines of transgenic mouse, gpt delta and Muta, for sensitivity of radiation-induced mutations in spleen. The gpt delta mouse could detect mutations induced by 2 to 8 Gy of gamma-rays with 2-times higher sensitivity than Muta mouse. The reason seemed to be that radiation induces predominantly deletion type mutation which is rather rare in natural background and gpt delta mouse can detect exclusively this deletion type mutation, whereas Muta mouse detects all types of mutation including the deletion. Next, we applied the gpt delta mouse to study mutation induction by tritiated water. A half ml of saline containing 0, 266 or 532 MBq of tritiated water was administered to the mice intraperitoneally and mutations in spleen were examined 7 days later. The estimated absorbed doses were 0, 3 and 6 Gy, respectively. With 3 Gy, the mutant frequency was elevated approximately 2-fold above control level, and it remained at a similar level with 6 Gy. These indicate that gpt delta mouse could be a good model animal to study genotoxicity of tritium.
