High temperature (35)Cl nuclear magnetic resonance study of the LiCl-KCl system and the effect of CeCl3 dissolution.
in Faraday discussions
| Description | The dynamics of Cl in in LiCl and KCl end members and mixtures have been detailed for the first time. The dissolution of Ce in the LiCl/KCl eutectic, as a Pu surrogate, changes the dynamics of the melt significantly with important implications for the potential effect of Pu. Faraday Discussions paper published, halide waste paper published |
| Exploitation Route | UK National Nuclear Laboratory has core expertise in molten salt re-processing that needs to be maintained - need fundamental work on the LiCl/KCl systems. May expand to fluoride systems through collaboration with SINAP (Shanghai Molten salt reactor programme) and Kairos Power, US start-up MS reactor company out of UC Berkeley. |

| Description | We have been asked to collaborate with the Chinese Academy of Sciences project to develop a Molten Salt reactor at Jiaiding (Shanghai). In July 2017, Dr Tao Su visited Cambridge for one week from the Chinese Academy of Sciences, Shanghai institute of Nuclear and Applied Physics (SINAP) to discuss the ongoing collaboration which has stalled slightly due to a delay in Chinese funding. The funding issue has been resolved and first results with SINAP researchers were discussed in a Zoom meeting in January 2021. We are collaborating with Professor Raluca Scarlet (UC Berkeley) on a US DOE NEUP application to research tritium and hydrogen speciation in molten salts. A pre-proposal was completed in summer 2020 and we were approved for a full grant application in November 2020. This was submitted on 8th February 2021. |

| PI Contribution | Prepared the pre-proposal document with Prof Scarlet and other partners and submitted in summer 2020, this was successful. Full proposal invited in the fall of 2020 and submitted in February 2021. Ths was funded and began in fall 2021 and Prof Farnan visited UC BErkeley 12-19 January 2022 to deliver doubly containment sample holders and review Be safety requirements. |
