Tanner, J. E.

Seventeen critical experiments employing an aqueous uranyl nitrate solution, 303 g U(93.0%)/l, in an annular tank were performed, with internal annular absorbers of polyethylene and/or stainless steel and/or an external annual reflector of carbon steel. Critical solution heights were determined by extrapolation of neutron multiplications as the height was increased. The o.d. of the solution annulus was 75 cm, and it was 8.92 cm thick. Modeling of the experiments with the Monte Carlo codes KENO-IV and MONK 6.2, and with the one-dimensional XSDRNPM transport code is reported here.
