Abstract : The control rod absorber section consists of composite plates joined by welding to form a rectangular parallelepiped. The composite plates consist of compacts of europium oxide in a stainless steel matrix that are clad with stainless steel by hot roll-bonding. These specifications cover materials and process required to produce the absorber sections. The procedural specifications are specific for manufacturing these components at ORNL, and represent a detailed guide for fabricators. It is recognized that because of differences in equipment, fabricators may be required to modify some of the detailed procedures to arrive at the same result. Prior approval for any deviation from these specifications must be approved by ALCO Products Inc., or its authorized representative.
