Book Description
A new method for weighing samples of plutonium dioxide is described. An efficient, reliable method of weighing samples and batches is important because a sample and batch may need to be weighed and treated a number of times before they are sufficiently pure for use. Accurate weighing and recording of all plutonium dioxide coming into or leaving the laboratory is also needed to satisfy accountability requirements. In the past, the necessary data were recorded by hand -- a time-consuming, error-prone procedure. This method was further complicated because plutonium cannot be handled safely outside a glovebox, and two operators were needed to record the data: one to weigh the plutonium dioxide and the other to record the weight. When vocal input to a computer is used, two operators are not needed to record data. An operator still handles the material in a glovebox, and measurement is still done within a glovebox, but with automated equipment, thus reducing the risk of radiation exposure and eliminating the need for two operators. This method allows the operator to determine from the glovebox monitor if the weights recorded are reasonable. If not, he can interrupt the procedure and reweigh the material. With computer recording of data, the chance for error is greatly reduced. All data are transmitted directly from the balance to the computer, where the result is displayed on monitors and recorded on a disk. 3 figs.
