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.

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 applicability of bremsstrahlung counting to in-situ measurements of high level tritiated water has been examined. A specially designed metallic vial fitted with a gold-coated beryllium window was prepared for the present examinations. Only tritiated water of a given amount was put into the vial. The volume dependence of the X-ray intensity showed that 5 cm3 of tritiated water is sufficient for measurements. It was found that the spectrum of X-rays induced by -rays consisted of only bremsstrahlung. The bremsstrahlung spectrum could be reproduced quite well by computational simulation. A good linear relation between the X-ray intensity and tritium concentration was obtained in the concentration range of 4 × 10-3-40 MBq cm-3. Furthermore, effect of nickel added as a model impurity to tritiated water was examined, and it was found that the tritium concentration can be evaluated from the X-ray intensity without any correction in the presence of impurity below 200 ppm.
