Christie, E R; Mar, B W

The Kukla assembly is a bare spherical oralloy assembly capable of producing self-limiting prompt critical fission bursts. Design and theory of operation are to a large extent based on the Godiva assemblies. The assembly was constructed to meet specific physics experimental requirements at the Lawrence Radiation Laboratory, Livermore. It is expected that the assembly will also find use as a source of fast neutrons in irradiation experiments. The assembly will be located in an existing concrete assembly vault. Reactivity assembly rates and amounts are designed to preclude a damaging excursion. In the unlikely event of a major excursion, it is well within the capabilities of the assembly vault to contain the effects of a 1O/sup 18/ fission accident. This accident is several times that which could be envisioned under any unfortunate series of events. No undue hazard or exposure to radioactivity would occur to either operating personnel or the civilian population as a result of such an accident. (auth)
