[en] This report documents all of the technical work performed by EG and G Idaho, Inc., from August 1981 through 1983 on Program Element-II (Blanket/Shield Thermal-Hydraulic/Thermomechanical Technology) of the Department of Energy (DOE) Office of Fusion Energy's First Wall/Blanket/Shield Engineering Technology Program. Following Section 1 which is a summary of the overall program, six major activities are described in separate sections. Section 2 is an evaluation of methods for simulation fusion bulk heating for thermal-hydraulic/thermomechanical testing. Section 3 is a survey of facilities which might be suitable for such testing. Section 4 describes the development of a strategy for resolving the identified thermal-hydraulic/thermomechanical data needs through a combination of nuclear and nonnuclear testing. Section 5 is a detailed plan for work in Phase I of Program Element-II. Sections 6 and 7 describe two activities undertaken by EG and G: the design of the nonnuclear solid-breeder concept integral simulation test, and the planning for a nuclear test which could follow it. Following these activities, EG and G participation in Program Element-II was terminated; thus, this report serves as the final report on technical work for Program Element-II at Eg and G
