Neutron experiments at Portsmouth for measuring flow and {sup 235}U content in UF{sub 6} gas

“…Computer simulations using the code MCNP (Briesmeister 1993) were performed after the experiments at Portsmouth were completed to gain insight on design parameters that could explain observed results or indicate improvements for future experiments. These computer simulations supplement those performed before the experiment and described in previous reports (Stromswold et al 1996a and1996b). The simulations did not attempt to reproduce the detailed geometry of the experimental setup.…”
