TAILIEUCHUNG - Behavior characteristics of hydrogen and its isotope in molten salt of LiF-NaF-KF (FLiNaK)

The results showed the behaviors of deuterium were consistence with the behaviors of hydrogen in FLiNaK. The difference between hydrogen and deuterium has not been observed upon the experimental research of the behavior characteristics of hydrogen and deuterium in FLiNaK, which suggested the results obtained here might apply equally to the behavior characteristics of tritium in FLiNaK. | Behavior characteristics of hydrogen and its isotope in molten salt of LiF-NaF-KF (FLiNaK) Nuclear Engineering and Technology 51 (2019) 490e494 Contents lists available at ScienceDirect Nuclear Engineering and Technology journal homepage: Original Article Behavior characteristics of hydrogen and its isotope in molten salt of LiF-NaF-KF (FLiNaK) Youshi Zeng, Wenguan Liu, Wei Liu, Yuan Qian, Nan Qian, Xiaoling Wu, Yu Huang, Shengwei Wu*, Guanghua Wang** Shanghai Institute of Applied Physics, Chinese Academy of Sciences, Shanghai, 201800, China a r t i c l e i n f o a b s t r a c t Article history: Experimental studies to investigate the behaviors of hydrogen in molten FLiNaK (LiF-NaF-KF) have been Received 22 March 2018 conducted at 500e700 C. On the basis of previous studies, the diffusivity and solubility of hydrogen in Received in revised form FLiNaK have been revised, and the expressions can be correlated to the following Arrhenius equations: 21 August 2018 DH2 ¼ 10 5exp ( 103/Rg$T) [m2/s] and SH2 ¼ 10 4exp ( 103/Rg$T) [mol- Accepted 8 October 2018 H2/m3/Pa], respectively. The behavior characteristics of deuterium in FLiNaK were studied and compared Available online 9 October 2018 with the hydrogen behaviors in FLiNaK. The results showed the behaviors of deuterium were consistence with the behaviors of hydrogen in FLiNaK. The difference between hydrogen and deuterium has not been Keywords: Hydrogen observed upon the experimental research of the behavior characteristics of hydrogen and deuterium in Deuterium FLiNaK, which suggested the results obtained here might apply equally to the behavior characteristics of Molten FLiNaK tritium in FLiNaK.
