PROBLEM TO BE SOLVED: To provide a fuel storage rack which can reduce the burden on welding workers by improving the weldability of austenite-base stainless steel containing elements of high neutron absorbability and has high quality and reliability, a filler rod for forming the rack, a member for jointing the rack and a method for manufacturing the rack. SOLUTION: This invention is characterized in that, in the fuel storage rack where prisms composed of the austenite-based stainless steel containing the elements of high neutron absorbability are integrally jointed with weld metal by welding and which stores reactor fuel assemblies, the weld metal is composed of austenite-base stainless steel containing a minor amount of Ti.
