DETAILED CONCEPTUAL DESIGN OF THE GRAPHITE PRIMARY SHIELD FOR THE ENRICO FERMI FAST BREEDER REACTOR. Technical Memorandum No. 23

Technical Report ·
OSTI ID:4143047
The detailed final conceptual design is presented for the graphite portion of the primary shield which surrounds the reactor vessel of the Ennico Fermi Atomic Power Plant. This shield will consist of blccke of plain and borated graphite or semi-graphite material arranged in layers within the primary shield tacks in specified patterns at each elevation. Each configuration was accurately determin ed by calculation. All objects in the shield area, such as pipes and pipe hangers, wiring, junction boxes, and other obstractions, were taken into consideration in the design. The boron concentration for the borated material is either 5 or 7 wt.% boron. In some areas in the thicker portions of the shield, brick filler blocks were specified. Steel gamma shielding was included in the upper regions of the shield. (auth)
