Heat Exchanger Design Charts

Description: From introduction: "The ORNL-ANP liquid-to-liquid heat exchanger design and development effort has been based on an exceptionally high performance matrix of closely-spaced small diameter tubes that permits practically pure counter-flow operation. In the course of full-scale aircraft power plant design work a number of charts for this type of heat exchanger has been prepared. These charts were intended in part to show the effects of the various parameters in a readily understandable form, and in… more

Possible water flow rates at DR and H Piles

Description: Estimated water flow rates at H Pile for various postulated conditions are given. The conditions under which the data are valid are as follows: (1) the estimated accuracy of the tube flow rates is {+-}5%, and of pile flow rates {+-}7%; (2) the pile flow rates are based upon the present tube geometry, orifice zone pattern and total flow at H Pile; (3) the flow rates should be increased about 2% if film-free slugs and tubes are considered; and (4) flow rates for enlarged fittings are based upon f… more

A Review of Corrosion of Uranium and its Alloys

Description: One characteristic of the corrosion of uranium is the accelerating destruction of the metal under both dry and humid conditions and throughout a wide temperature range. Another corrosion property is the fracturing and fragmentizing of the oxide products. This results in an accelerating or decelerating growth law being operative at a particular time. This time is determined by whether the oxide ruptures rapidly or slowly compared to the rate of growth of the unfractured oxide. The reaction with … more
