“…The process takes advantage of the small mass difference between isotopes, causing them to condense at different temperatures. The mixture is cooled to very low temperatures around 20-24 K, causing the isotopes to liquefy and then vaporize at different points, allowing for their separation [20,23]. The process is energy-intensive due to the extremely low temperatures required and the need for continuous distillation.…”

Liquid phase catalytic exchange (LPCE) appears a highly promising technology for separating hydrogen isotopes due to being less energy-intensive and having a high separation factor. This paper provides an overview of the current development of the hydrophobic catalysts used in the LPCE process, including the LPCE fundamentals, factors influencing its effectiveness, and proposals for future research areas. This paper specifically reviews the active metal catalysts, catalyst supports, operating temperatures, and molar feed ratio(gas-to-liquid,G/L). The addition of a second metal such as Ir, Fe, Ru, Ni, or Cr and modified catalyst supports showed enhancement of LPCE performance. Additionally, the validated optimized temperature of 60–80 °C and G/L of 1.5–2.5 provide an important basis for designing LPCE systems to improve separation efficiency. This paper concludes by highlighting potential research areas and challenges for future advancements in the sustainability of LPCE for hydrogen isotope separation, which include the optimization, scalability, techno-economic analysis, and life-cycle analysis of modified catalyst materials.

“…Cryogenic distillation at 20-26 K is usually utilized to separate hydrogen isotope for a fusion reactor [21,22]. In the design, three product streams are produced by ISS, these are two fuelling gases (tritium with deuterium for pellet injection, deuterium with purity of 99% for Neutral Beam Injection) and a low tritium H 2 off gas (Fig.…”

“…have been extensively investigated. As a result of research activities, cryogenic distillation (CD) combined with catalyzed isotopic exchange between hydrogen and liquid water (LPCE), was recognized as one of the most suitable technologies for removing of tritium from tritiated water produced in CANDU reactors or at International Thermonuclear European Reactor (ITER) [1][2][3].…”

Based upon the authors' long experience and upon a literature review, this paper presents an assessment regarding up-to-date R&D activities related to development and application of liquid phase catalytic exchange (LPCE) technology for tritium separation from tritiated water, produced in fission and fusion nuclear reactors. The assessment is focused on key elements of the LPCE process, mixed catalytic packing and as a result of the assessment, few recommendations for selecting the most suitable mixed catalytic packing are given. A new improved mixed catalytic packing (COMPACK C-P 001) was manufactured and proposed to be used in the future Tritium Removal Facility from Cernavoda CANDU NPP (Romania).
