Experimental Fabrication of a Lightweight Control Rod

Description: Abstract: "The possibility of fabricating a lightweight control rod from one of several high cross-section materials was investigated. The major effort was directed toward the development of a titanium-clad rod containing a composite core of 25 weight per cent Gd2O3 in a matrix of titanium. Experimentation on both subscale and full-scale control-rod cores showed that the fabricating behavior of the two was not analogous. To roll the full-scale core successfully, it was necessary to lower the ox… more

Final Report on Purification of Thorium Nitrate by Solvent Extraction With Tributyl Phosphate: 2. Mixer-Settler Pilot Plant Investigations

Description: From abstract: "This report describes the construction and operation of a mixer-settler pilot plant for the purification of mantle-grade thorium nitrate. The liquid-liquid extraction process utilized 30% tributyl phosphate - 70% 'Solvesso-100' as the organic solvent and nitric acid as the salting agent. Continuous steady-state operation of the equipment was demonstrated, with very good recovery of thorium."

Interim Report on the Radioactive Carbonate-Hematite Veins Near Salmon Bay, Prince of Wales Island, Southeastern Alaska

Description: From abstract: In the vicinity of Salmon Bay near the northeastern end of Prince of Wales Island, southeastern Alaska, samples obtained in 1951 from narrow, steeply dipping, carbonate-hematite veins contain as much as ,O.07 percent equivalent uranium. The average grade of these veins cannot be reliably stated because no systematic sampling has been done. No uranium or thorium minerals have been identified. Several chemical analyses indicate only a few thousandths percent uranium. Most of the ra… more

Preliminary Report on Uranium-Bearing Pliocene (?) Rocks in the Split Rock Area, Central Wyoming

Description: From abstract: A sequence of slightly radioactive Pliocene(?) rocks in the Split Rock area of central Wyoming is at least 600 feet thick, underlies an area of more than 25 square miles, and consists of alternating beds of tuffaceous shale, sandstone, and pumicite. Only a small part of the section has been examined. In addition to the uranium content of the strata, there has been secondary concentration of uranium in brecciated limestone similar to spring deposits that could be of Pliocene or Pl… more

The Effect of Gaps on Pile Reactivity

Description: From abstract: "The variation of the reactivity of a pile as a function of width of a transverse gap is obtained. The method involves first finding the boundary condition satisfied by the flux at the gap face. This, in principle, provides enough information for a complete solution of the pile equations. A method for calculating the reactivity change is presented. The calculated reactivity is compared with experiment and a brief discussion of the validity of the approximations is given."

Analysis of Bulk Shielding Facility Neutron Dosimeter Data

Description: Technical report calculating "effective removal cross sections" for Pb, Fe and O from measurements of fast neutron does in the water surrounding the BSF reactor. The values for Pb and Fe agree quite well with those previously determined from Lid tank data, whereas that for O is somewhat lower. [From Abstract]

Final report on Production Test No. 105-1-MR -- Poison column control during reactor operation

Description: The lack of control rod capacity in the reactors with nine rods is causing significant production losses. The present control system, which functioned satisfactorily at a 300 MW equilibrium power level, is unable to counteract the larger startup reactivity transient effects at the current high power levels. This lack of strength causes the power level to be restricted during startup. The control system is also not flexible enough to prevent outages for the discharge of temporary poison. (1) A m… more

A Description of the Acetone-Dye Solution Method of Demarcating a Leak Process Tubing While in the Pile

Description: Abstract: "A method has been devised and successfully used for marking a leaking pile process tube prior to its removal from the pile, such that subsequent location of the leak is more easily accomplished. An acetone solution of Testor's Dark Red Airplane Dope is poured into the suspect tube. The solution leaks from the hole and stains the surrounding area a light pink. To date the method has been used on tubes 3573F, 0486F, 0867F, and 3670F."

Description: NpC and Pu{sub 2}O{sub 3} have been identified by x-ray diffraction. NpC is face-centered cubic, NaCl structure with a = 5.004 {+-} 0.005 A Pu{sub 2}O{sub 3} is isomorphous with the hexagonal ''A form'' for the rare earth sesquioxides with a = 3.840 {+-} 0.004 A; c = 5.957 {+-} 0.006 A and has essentially the same atomic parameters at La{sub 2}O{sub 3}.
