The Reaction of Hexachloropropylene With Metallic Oxides (open access)

The Reaction of Hexachloropropylene With Metallic Oxides

Abstract: Twenty-two metallic oxides were refluxed with hexachloropropylene. The anhydrous chlorides or other products formed are described for each oxide. The reactions were particularly vigorous with higher valent oxides of the fifth and sixth group elements.

Pile Kinetics (open access)

Pile Kinetics

From abstract: "A pile will run steadily at an arbitrary level if it is just critical. For a pile not at equilibrium, equations of motion can be set up that contain as variables the pile power, the number of delayed neutron emitters and, in case it is of importance, also the pile temperature. The coefficients will depend on the average lifetime of the neutrons in the pile, the fractions and periods of delayed neutrons, temperature coefficients of resistivity and similar quantities. For a definite 'excess resistivity', which may be positive or negative, the power level will change exponentially with time with periods determined by the so-called 'labour' relation. For control and safety problems the transient behavior of the pile under reactivity changes has to be investigated. A number of limiting cases can be solved explicitly. A general method for the solution of the pile equations is available for small deviations from a steady state. In this case a pile impedance can be defined in close analogy to electric circuit theory."

Effect of Routing Upon Temperature of Cooling Stream (open access)

Effect of Routing Upon Temperature of Cooling Stream

With discussion under way concerning power production by chain reacting piles, it becomes pertinent to consider the ration of the temperature of the hottest spot in the pile to the average exit temperature of the cooling stream. This is important because the temperature of the hottest spot in the pile is one of the limiting factors in determining the maximum power at which a pile can be operated. However, the higher the temperature of the emerging cooling stream, the more efficient can be the thermal engine operated by it. Thus the ideal situation is to have the average exit temperature of the cooling stream as near as possible to the hottest temperature of the hottest spot in the pile.
