Specifications were prepared for control rod fuel elements for the Core Il of PM-2A. These stainless steel-base fuel components of thin plate-type construction and containing a dispersion of UO/sub2/ were successfully used in powering the Army Package Power Reactor. The component, which consisted of sixteen composite fuel plates joined by brazing, was designed for radioactive service in pressurized water. Tests for qualification of fabrication procedures and specifications covening loading, materials, and processing are presented. Also included are drawings and the process flow diagram. (M.C.G.)

Specifications were prepared for the control rod absorber sections for Core Il of Army Reactor PM-2A. The neutron absorber section was composed of composite plates welded into the form of a rectangular parallelepiped. The composite plates were made of compacts of europium oxide in a stainless steel matrix clad with stainless steel by hot-roll bonding. Specifications covering materials and processes are included in the repont along with fabrication qualification tests. (M.C.G.)

Specifications were prepared for stationary fuel elements for PM-2A Core Il. Stainless steel-base fuel compcnents of thin plate-type construction and containing a dispersion of UO/sub 2/ were successfully used in the Army Reactor (SM-1). The component consisted of eighteen composite fuel plates joined by brazing, and was designed for radioactive service in pressurized water. Fabrication qualification tests and specifications covering loading, materials, and processing are presented. Also included are applicable drawings and the process flow diagram. (M.C.G.)

Stainless steel-base fuel components of thin plate-type construction and containing a dispersion of UO/sub 2/ were successfully employed in powering the Army Package Power Reactor.
