Determination of Li$xup 6$ in Aqueous Solution by Neutron Activation Analysis

Description: A method for determining the concentration of Li/sup 6/ in aqueous solution was tested using the nuclear reactions Li/sup 6/(n, alpha )H and O/sup 16/(H/sup 3/,n)F/sup 18/. Annihilation gamma radiation of induced 1.87-hr F/ sup 18/ radioactivity was counted with a welltype scintillation counter, and the radioactivity per millimole of lithium was found to be independent of lithium concentration below about 0.2 moles/liter. The sensitivity limit for detecting lithium is less than 0.1 micromole (0… more

Determination of Li6 in Aqueous Solution by Neutron Activation Analysis

Description: A method for determining the concentration of Li6 in aqueous solution has been tested using the nuclear reactions Li6 (n,α)H3 and O16 (H3,n)F18. Annihilation 7 radiation of induced 1.87 hour F18 radioactivity was counted with a well-type scintillation counter, and the radioactivity per millimole of lithium was found to be independent of lithium concentration below about 0.2moles/liter. The sensitivity limit for detecting lithium is less than 0.1 micromole (0.0075 micromole Li6).

Neutron Age Calculations. (Homogeneous Systems)

Description: In an earlier study on criticality conditions for homogenous mixtures, 2/cm^2 was used as the neutron age for all mixtures of water and uranium. At the higher H/U ratios (low uranium concentration), the calculated critical parameters were in good agreement were in good agreement with experimental data. At the low H/U ratios (high uranium concentrations) the calculated critical parameters were smaller than the experimental ones (more conservative from a nuclear safety point view). These results … more

The Palmolive cycle at Hanford

Description: The Palmolive program is directed toward the recovery of neptunium-237 and production of plutonium-238. The neptunium is recovered during the chemical processing of irradiated uranium and is purified and fabricated into target elements. The target elements are irradiated to produce plutonium-238 by neutron capture of neptunium-237 and are processed to provide plutonium for shipment to the final customer and neptunium for recycle within the system. This report summarizes a preliminary engineerin… more

Design of an Eddy-Current Brake for a Sodium-Cooled Nuclear Power Reactor

Description: Two eddy-current electromagnets to act as brskes were designed and installed in the sodium-cooled nuclear pcwer reactor SRE to throttle sodium flow throughout the reactor after shutdown in order to maintain a constant reactor temperature gradient. One brake was used on the primary piping system, the other on the secondary system. It was determined that the eddy-current brake should cause a dragging pressure of 0.3 psi at a flow rate of 12 gal/min. The flux density necessary to produce this pres… more

Fuel element recovery and its relationship to uranium scrap

Description: At the request of the manager of Process Engineering, a study was made of the fuel element recovery operation and its relationship to the HAPO uranium scrap losses. Three fundamental questions formed the basis for this study. They are: What is the amount of the yearly uranium scrap loss at HAPO? What contribution does the existing fuel element recovery process make to this loss? What should be done to reduce this loss? The purpose of this report is to answer these questions and make specific re… more

Laboratory Production of Fine Grain Nuclear Emulsion

Description: Abstract: "Nuclear emulsion has been made in a manner similar to that of Demers and of Perfilov. An attempt has been made to achieve the grain size and sensitivity of Perflov's type P-9 Sensitive emulsion. Silver bromide grain sizes of essentially the same average size as Perfilov's were made from precipitations carried out over a narrow range of pAg's. Three brands of gelatin were tried. High sensitivity has not been achieved."

A proposal for equitable IPD electrical power cost distribution between areas

Description: Assistance has been requested by Financial Operation to determine the percent of firm and interruptible power used in each area for cost distribution purposes. Also, Power Operations have suggested that the power cost distribution be reviewed. In consideration of these requests, and with the use of improved demand instrumentation within the 151-B, D, and F substations, a proposal for equitable IPD electrical power cost distribution between areas is presented for acceptance or comment by Area Ma… more

Stress Analysis of Bulk Effluent System Components in B and C Reactors

Description: This report presents a study of the stresses induced in the elbow and downcomer of the B and C Reactors (bulk effluent systems) by flow momentum and pressurization effects. It is desirable to ascertain the limitations on the bulk outlet temperatures and flow rates from a stress viewpoint; the elbow, top coverplate of downcomer, and top baffle plate being the most severely stressed components.

Accident in Continuous-Dissolver Pilot Plant of Fluoride Volatility Project on May 15, 1957

Description: A series of explosions, estimated at five, occurred over a period of ten seconds within the continuous dissolver pilot plant, of the Fluoride Volatility Project on May 15, 1957. The explosive reactions occurred in the dissolver vessels as a result of violent chemical reactions between uranium and an interhalogen mixture. Just what the conditions were which triggered the explosions, have not been definitely established. Nevertheless, based upon the evidence which has been collected, several poss… more

Accident in Continuous-Dissolver Pilot Plant of Fluoride Volatility Project on May 15, 1957

Description: The so-called Fluoride Volatility Processes refer to several proposed non-aqueous methods of processing irradiated fuel elements. In each of these methods, the uranium is fluorinated to UF6 and then decontaminated by distillation. One of those methods, involving the direct fluorination of the uranium by bromine trifluoride (BTF), has been under investigation at BNL since 1950. In 1952, it was demonstrated at BNL that uranium, as UF6, could be satisfactorily decontaminated by distillation in sma… more

Experimental Investigation of Wing-Aileron Flutter Characteristics of a 1/4-Scale Dynamic Model of the X-1E Airplane

Description: Report presenting testing of some of the flutter characteristics of a 1/4-scale model of the X-1E airplane wing and aileron in the transonic tunnel. The wing was tested as part of a complete model of an airplane over a Mach number range of 0.4 to 1.05 and a range of angles of attack. No stall flutter or classical flutter was encountered, but the results indicate that unstable aerodynamic damping is present on the ailerons at transonic speeds. Results regarding free play, angle of attack, ailero… more
