ENERGY RECEPTION AND TRANSFER IN PHOTOSYNTHESIS

Description: The basic information about the path of carbon in photosynthesis is reviewed together with the methods that were used to discover it. This has led to the knowledge of what is required of the photochemical reaction in the form of chemical species. Attention is then directed to the structure of the photochemical apparatus itself insofar as it is viewable by electron microscopy, and some principoles of ordered structure are devised for the types of molecules to be found in the chloroplasts. From t… more

Analyses and correlations of HAPO rupture experience with natural uranium material

Description: One of the major factors restricting reactor power levels is the incidence of ruptured slugs. The primary purpose in studying ruptures is to determine how reactor operating variables affect rupture rates. With this knowledge reactor operating conditions may be adjusted or controlled in the manner that will optimize reactor production. In addition, knowledge of rupture rate relationships are useful in fuel element development and in overall economic studies of existing and proposed reactors and … more

Possible explanation of 105-K graphite stack distortion

Description: In the course of trying to predict the shape of NPR horizontal rod and process tube channels after several years of operation, data from 105-K were referred to. While looking at the 105-K data the following possible explanation of the ``K`` reactor distortion phenomenon occurred to me. It is written up in this document as a possible aid to those responsible for evaluating the stack distortion problem in the ``K`` reactors. Data and references to data are presented first and then an analysis of … more

Proposal for irradiation of uranium swelling behavior capsules

Description: The swelling behavior of unalloyed clad uranium operating with a cladding surface temperature of 250--350 C and fuel temperatures from 450--750 C is of importance for Hanford`s fuel element development work. To obtain information on the effect of cladding restraint, exposure, and the above temperatures, on uranium swelling rates, a series of experiments is proposed for irradiation in Hanford reactors. The experimental assemblies consist of uranium fuel rods supported concentrically in an alumin… more

Turret: A High Temperature Gas-Cycle Reactor Proposal

Description: A nitrogen-cooled graphite-moderated nuclear reactor experiment is proposed to drive a closed-cycle gas turbine power plant at 1300 deg F. The annular core of the reactor can be rotated inside the reflector to permit fuel loading and discharge while operating at full power. Small cylindrical fuel elements of graphite are solutionimpregnated with partially enriched uranium. The fuel is recycled by incineration of the elements, chemical fresh graphite tn a small batch process. The unclad, uncoate… more

HRP-CP: Conclusions Concerning the Predicted Behavior of Insoluble Corrosion and Fission Products in the HRT

Description: Information available from HRP-CP development studies was summarized amd used as a basis for predicting the probable behavior of corrosion and fission product solids in the HRT and its associated chemical processing plant. Operation of the chemical plant will probably limit the HRT circulating solids concentration to between 10 and 100 ppm; quantitative predictions are uncertain due to uncertainties concerning the charaeteristics of reactor solids and the effects of rcactor geometries.

Determination of Thorium in Uranium Ores and Feeds by Solvent Extraction Employing Thenoyltrifluoroacetone

Description: The thenoyltrifluoroacetone (TTA) extraction method has been investigated for the determination of microgram concentrations of thorium in uranium ores and concertrates. The tolerance limits for eighteen elements commonly found in uranium ore concentrates were established. The effect of phosphate on estraction of thorium was studied. Cobalt, copper, tin, and bismuth were found to seriously interfere with the Thoron method for the determination of thorium after a TTA extraction. A TTA extraction … more

JOFIT--A Least Squares Bessel J$sub 0$ Fitting Program for the IBM-704 Computer

Description: The JOFIT code fits, by a least squares technique, the curve y = A J/sub o/STAB(x-C)! from 4 to 500 points of observed data, computing the parameters A, B, C and the standard deviation of the final values of A, B, C, i.e., S/sub A/, S/ sub B/, S/sub C/. It is also possible to investigate the error in a region about the final values of A, B, C by computing the sums of the squares of the residuals at a series of points in this neighborhood. Typical computing and editing time for a 50 point proble… more

Experimental Study of Ballistic-Missile Base Heating with Operating Rocket

Description: "A rocket of the 1000-pound-thrust class using liquid oxygen and JP-4 fuel as propellant was installed in the Lewis 8- by 6-foot tunnel to permit a controlled study of some of the factors affecting the heating of a rocket-missile base.

Investigation of Inlet Control Parameters for an External-Internal-Compression Inlet From Mach 2.1 to 3.0

Description: "Investigation of the control parameters of an external-internal compression inlet indicates that the cowl-lip shock provides a signal to position the spike and to start the inlet over a Mach number range from 2.1 to 3.0. Use of a single fixed probe position to control the spike over the range of conditions resulted in a 3.7-count loss in total-pressure recovery at Mach 3.0 and 0 deg angle of attack. Three separate shock-sensing-probe positions were required to set the spike for peak recovery f… more

The Uranium-Nitrogen-Carbon System

Description: The ternary system uranium- nitrogen- carbon has been studied at 1800 deg C under vacuum and under a 1atm. nitrogen pressure. There is complete solid solubility between UN and UC, and essentially no solid solubility of nitrogen in UC/sub 2/ or U/sub 2/C/sub 3/ or of carbon in U/sub 2/N/su b 3/. At 1800 deg C the two-phase field, U(C,N) and UC/sub 2/, and the three-phase field, U(C,N), UC/ sub 2/, and C, exist in vacuum or argon. At 1 atm. of nitrogen, the uranium nitrides are more stable than t… more
