![]() ![]() The corrosion of Zircaloy 2-clad, U-Zr fuel plates in 550☏ degassed water. Slip ratios are also plotted as a function of inlet water velocity at 150 and 250 psig, indicating that there is no significant pressure effect on the slip ratio pattern in going from 150 to 250 psig. Data from single channel forced and natural circulation boiling density tests at 150 psig are summarized. These plots show modified Martinelli-Nelson factors as a function of slip ratio and exit and local void fraction. The analytical and experimental studies made of the 600 psi, unrestricted, single-channel circulation loop (Armadilla) are described, and preliminary data are plotted. Data given on boiling heat transfer studies include the ratio of steam-to-liquid velocity as a function of the variable inlet temperature, power, flow, and pressure. The design of a boiling D 2O reactor is briefly discussed. Supporting and Alternate Resign Research and Development. The schematic for the emergency airlock doors for the EBWR is shown. A simplified line diagram is also given of the EBWR electrical system. A schematic plan view is shown of the EBWR power plant and control areas. Estimated flows in this system are also given, and the operation of the system is briefly discussed. A schematic flow diagram of the air drying and fluid recovery system is given. The reactor water purification system is discussed. An emergency boric acid injection system to reduce the reactor core activity below criticality was designed. The physical arrangement of this shielding is also described. Fast and thermal neutron flux calculations for the heavy water-reflected EBWR in the adjusted shield are summarized. A redwood, steel, and Celotex blast shield for the pressure vessel is also more » shown. The pressure vessel containment structure is described in detail, and calculated impact loading stresses are summarized. The mechanical arrangement of the thermal shielding is given. Calculated heat generation and thermal stresses in the pressure vessel wall for each type of thermal shielding are tabulated. The prototype test facility for the control mechanisms is also shown. The deceleration curve for the drive shaft at 600-psig operation is given. Designs of the EBWR control rod and drive mechanism are given. Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types.Corrosion of Zircaloy-2 clad stainless steel thimbles is shown. You can find metric conversion tables for SI units, as well as English units, currency, and other data. Since atmospheric pressure at sea level is around 14.7 psi, this will be added to any pressure reading made in air at sea level.Ĭ provides an online conversion calculator for all types of measurement units. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. Psia to psi, or enter any two units below: Enter two units to convert From: ![]() You can do the reverse unit conversion from
