Feasibility study for removal of SiC coating in HTGR-type fuel by F2-fluorination
- 1. Japan Atomic Energy Research Inst., Tokai, Ibaraki. Tokai Research Establishment
Description
A decladding process only by the gasification reaction, is proposed for the TRISO-type particle fuel through fluorination experiments of SiC and PyC. The process may be adapted to the aqueous separation processes such as Thorex or Purex by framing a ''Burn-Fluorination-Reburn-Leach'' flowsheet. Feasibility of the proposed flowsheet was confirmed by a boat experiment with unirradiated coated particle. By both experiment and calculation, optimization of the fluorination step is shown to be the key problem for minimum kernel loss. (auth.)
