Cutts, B

Detailed calculations of the nuclear properties of the core of a Calder Hall Thermal Reactor have been made. The zones of different channel size have been allowed for, but the Wigner gaps have been assumed to have a uniform size throughout the core. The different properties of graphite in the core and reflector and the different thicknesses and structures of the reflector sections around and at the ends of the core have been considered. The quantity and enrichment of U required to fill an outer zone in order that the pile shall just run at 180 Mw heat rating, when the inner zone is loaded with natural U, is given for inner zone radii from zeroto 12 ft.
