Physicochemical conditions for effective hydrogen isotope storage and delivery in a uranium bed

This paper proposes physicochemical conditions for effective hydrogen isotope storage and delivery in a uranium bed. Effective physicochemical conditions for tritium storage and delivery are obtained by manipulating initial depleted uranium (DU) temperatures and hydrogen pressures and applying three distinct operation scenarios. These novel physicochemical conditions and operation scenarios enable higher and more constant hydrogen recovery and delivery rates. The results presented can be used to facilitate the storage and delivery of tritium for environmental protection and waste management in nuclear fission reactors, and for future commercial use in isotope industries and nuclear fusion fuel systems.
