Calibration of Experimental Model of Tritium Storage Bed

Abstract

During the water detritiation process most of the tritium inventory is transferred from water into the gaseous phase. Tritium is further enriched and finally extracted and safely stored. The control of tritium inventory is an important issue from several points of view, viz., (i) tritium is an expensive material, (ii) safeguard-tritium is considered as nuclear material of strategic importance, (iii) safety-tritium is a radioactive material, (iv) requirements for documented safety analysis report (to ensure strict limits on the total tritium allowed) and (v) for evaluation of accident consequences associated with that inventory. Large amounts of tritium can be stored, in a very safety manner, as metal tritides. An experimental model of a tritium storage bed with integrated system for in situ tritium inventory accountancy was designed and manufactured at ICIT Rm. Valcea. The calibration curve and the detection limit for this experimental model of tritium storage bed were determined experimentally.
