Results of Differential Bed Study of the Kinetics of the Absorption of UF6 on Sodium Fluoride

Description: One step in the Volatility process for power reactor fuel reprocessing involves the absorption and subsequent desorption of UF6 from NaF pellets in fixed beds. In 1958 an experimental study of the kinetics of absorption of HF on NaF beds was made. The purpose of this work was to extend the study to the kinetics of UF6 absorption on NaF. The results should be useful in the design and operation of the Volatility process.

Problems of a Small Leak Between the Flow Monitor and Heated Section of a PRTR Process Tube

Description: The result of a leak in a PRTR process tube between the flow monitor and the heated section would be to increase the flow through the monitor, but to decrease the flow through the heated section. The concern for the case of small leaks is whether the increase in flow through the flow monitor is sufficient to cause a high flow tip and a reactor scram for the condition where the flow through the heated section is reduced to the point to cause excessive fuel element temperatures.

On the Green's Function for Two-Dimensional Magnetohydrodynamic Waves. II

Description: "As an extension of an earlier paper the Green's function is evaluated for the Lundquist equation linearized about uniform magnetic field, constant matter density, and zero flow velocity. It is assumed that all quantities are functions of two space variables and time only. In the general magnetic field configuration considered here a pure Alfvén disturbance no longer exists; there is instead a wave with properties of both the Alfvén and fast‐slow disturbance."

An Algorithm for Construction Feasible Schedules and Computing Their Schedule Times

Description: "An algorithm for the generation of feasible schedules and the computation of the completion times of the job operations of feasible schedule is presented. Using this algorithm, the distribution of schedule times over the set of feasible schedule—or a subset of feasible schedules—was determined for technological orderings that could occur in a general machine shop. These distributions are found to be approximately normal. Biasing techniques corresponding to “first come first serve,” random choi… more

The Numerical Solution of a Parabolic System of Differential Equations Arising in Shallow Water Theory

Description: "A finite difference approximation to a non-linear set of parabolic differential equations arising in shallow water theory is given. These difference equations were used to determine the shape and rate of propagation of a hum of fluid down a channel of constant depth. The hump of fluid was found to spread instead of steepen, as is the case in the usual shallow water theory."
