PERMEATION MEMBRANE FILTER FOR HYDROGEN IN Na AND HYDROGEN REMOVAL METHOD USING IT AND HYDROGEN MONITORING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a permeation membrane filter for hydrogen in Na, which is capable of permeating only hydrogen efficiently from liquid Na, and hydrogen removal method using it and hydrogen monitoring method. SOLUTION: A permeation membrane filter for hydrogen in Na forms a plated layer 2 consisting of a Na resistive metal selectively permeating only hydrogen on the surface of a base consisting of porous ceramics. Only hydrogen in Na is sucked into vacuum side and removed by way of the hydrogen permeation membrane filter and then hydrogen concentration in Na is checked by using a detector installing the hydrogen permeation membrane filter.
