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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

In this work, experimental and mathematical substantiation of the possibility of using the new RCTU-4 hydrophobic catalyst [0.9 mass % Pt/styrene and divinylbenzene (SDVB)] in the separation of protium-tritium isotopic mixtures by a two-temperature catalytic exchange method in a water-hydrogen system was carried out. Variation of the synthesis parameters of the support and the catalyst allowed a significant increase in the activity (≥50 s–1) and heat resistance (≈550 K) of the investigated sample compared to the previously used catalyst RCTU-3SM (kexp = 12 s−1; heat resistance = 388 K). The mathematical model presented in the paper considers three phases (liquid water, steam, and hydrogen gas) and allows optimization of dual-temperature installations in the water-hydrogen system for any isotopic mixtures.
