A control rod is used to control the reaction of a nuclear reactor. The control rod comprises one or more internal rodlet(s) and a hafnium skin that serves as the outermost layer, rather than a stainless steel cladding. Several variations on rodlets are contemplated. The rodlets are made of hafnium or Ag-In-Cd. The resulting control rod, due to the lack of a stainless steel cladding, has a greater rod reactivity worth, increased weight, and high flexibility.
