REPORT ON THE PROCESSING OF PITCHBLENDE

A detailed description of the processing of pitchblende ores used at the Port Hope, Canada, refinery is given including both the recovery and purification of U and Fu. The health hazards present in the processing are discussed, and recommendations are made which will insure adequate health protection. (L.T.W.)

Comparison of observed and calculated flattening at 105-D (open access)

Comparison of observed and calculated flattening at 105-D

The total power output of a unit may be represented by the power output of the most productive tube or tubes multiplied by a quantity designated as the ``number of effective tubes.`` The number of effective tubes observed at 105-D under two different arrangements of poisoned columns has been compared with values of this quantity calculated from theory. It was found that in each case the observed number of effective tubes was about 5% less than the ideal number obtainable by an optimum arrangement of the poison. In the case in which two poisoned columns in the pile took up 110 ih it was found that the loss consisted of 2% due to the necessary presence of a control rod in the pile and 3% due to the fact that the actual arrangement of the poison was not the optimum one. In the case in which a single, off center, poison column took up 60 ih, it was found that very little of the loss was due to the presence of the control rod and almost all of it was due to the eccentric position of the P-column. As a further result of this study, it was found that, apart …

The Site B Foundry (Final Report on Part I of P.A. No. 151-ML-54-2, F.S. 41) (open access)

The Site B Foundry (Final Report on Part I of P.A. No. 151-ML-54-2, F.S. 41)

The Site B Foundry is equipped for the melting and casting of tuballoy and its alloys. Castings weighing up to 750 pounds and as long as 40 inches can be made. Melting can be carried out in the vacuum, in inert gases or under fluxes. Heating is by high frequency induction. A description of the generally foundry layout, the furnace construction and operation, and of the auxiliary equipment is given in this report. The casting technique used in the Site B Foundry is designed to minimize piping and cold shuts in the billets. The top of the mold is kept hot and freezing of the billet takes place from the bottom. This hot topping minimizes piping. Controlled pouring into warm molds minimized cold shuts.
