Cobalt removing device for LWR type reactors

Purpose: To obtain a high temperature filter having a good adsorption performance of cobalt materials in reactor water and with less possibility of washing out due to the velocity fluctuations of the reactor water. Constitution: Since the sintered body of stannic oxide prepared by powder metallurgy is very much excellent in the cobalt adsorbing performance, filters made of sintered SnO2 material are disposed within a reactor water recycling system as a cobalt removing device for use in BWR type water. Specifically, SnO2 sintered into porous structure by means of powder metallurgy and incorporated with other metals or alloys as a binder for improving the mechanical strength is employed in the shape of a honeycomb configuration or the like.
