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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Tritium exists in environmental samples as: (i) Tissue Free Water Tritium (TFWT) and associated with the organic matter (OBT) under two forms; (ii) bound to oxygen and nitrogen atoms into the material (E-OBT); (iii) bound to carbon atoms into the material (NE-OBT). The analysis of the NE-OBT fraction requires the elimination of E-OBT prior measurement. This operation is generally performed through labile exchange supposing that only isotopic exchange occurs. Most of the time, the recovered exchange water are coloured indicating that other mechanisms arise.To identify and to understand these mechanisms, the combination of two analytical tools, a CHNS-O elemental analyser and a spectrophotometer was used. NE-OBT analyses are performed on numerous environmental samples. In this work aliquots of those samples, under their solid form, were taken before and after labile exchange for elemental analysis purposes. In the same time the exchange waters were stored until spectrophotometric measurements. Solid analysis show that an evolution of the elemental composition could occur during the labile exchange with potential analytical impact. Moreover, it gives first ideas on which molecule could be solubilised. This trend is confirmed through spectrophotometric analysis where bands are observed for wavelength characteristics of proteins, amino acids, nucleic acids. Those preliminary results obtained using both techniques are promising but needs confirmation in the near future to determine to which extent an analytical impact could occur and to complete the identification of soluble molecules.
