The use of magnetic flux compression to isentropically compress matter is summarized. Details of the process used to extract boundary data from the flash radiographs and the design criteria for the containment of very compressible material are discussed. Finally, suggestions for improvement of the next generation of experiments are made.

To minimize radiological risk from the operation of a waste management system, performance limits on volatilization, particulate dispersion, and dissolution characteristics of solidified high level waste must be specified. The results show clearly that the pre-emplacement environs are more limiting in establishing the waste form performance criteria than the post-emplacement environs. Absolute values of expected risk are very sensitive to modeling assumptions. The transportation and interim storage operations appear to be most limiting in determining the performance characteristics required. The expected values of risk do not rely upon the repositories remaining intact over the potentially hazardous lifetime of the waste.

This report details the federal and state laws regarding animal baiting and fighting. In general, this report found three types of state statutes on this matter: specific legal prohibition aimed at stamping out a practice considered either distasteful, immoral, or a nuisance; general animal cruelty provisions enacted into law which may or may not be held applicable to baiting and fighting or any or all animals, and which may be not be enforced against those involved in such activities; and the absence of statutory restraints due either to open acceptance of animal baiting and fighting as a harmless activity or due to lack of concern over the matter.

Results are presented of a study aimed at determining the feasibility of using chemical getter beds to scavenge tritium from inert gases. Two types of getter bed, fixed and fluidized, were considered, using cerium as the getter material. Mathematical-modeling results and capital-cost estimates indicate that not only is the gettering approach technically feasible, it could lead to considerable cost savings over catalytic oxidation, the tritium-removal method traditionally used.

Methods for determining trace amounts of beryllium in urine, hair, fingernail, and fecal samples are described. These methods involve use of a Perkin-Elmer Model 503 spectrophotometer equipped with an HGA-2100 graphite furnace. Lanthanum was used as a masking and enhancing agent, and recoveries were determined by direct comparison with aqueous standards. The hair and fingernail samples were degraded readily in a nitric acid-perchloric acid mixture, and the feces were digested rapidly using a ferrous ion, hydrogen peroxide method. The urine samples were run by two methods: (1) direct and (2) coprecipitation. Nanogram-per-gram levels of beryllium were recovered from all tissues and fluids. All recoveries varied from 90 to 110 percent with relative standard deviations of less than 13 percent.

A method for determining trace amounts of beryllium in the presence of various anions and cations is described. The method involves use of a Perkin-Elmer Model 503 spectrophotometer equipped with an HGA-2100 graphite furnace. The absorption signal from 20 ng/ml of beryllium varies significantly from acid to acid, and both 5 percent (V/V) nitric acid and 5 percent (V/V) sulfuric acid were studied as possible analysis solvents. Absorption signal enhancement and suppression caused by the presence of other chemicals appears similar in either solvent. Concentrations of more than 0.1M hydrochloric and hydrofluoric acid suppress the signal in both solvents. Group II cations, lanthanum, cerium, chromium, molybdenum, tungsten, manganese, aluminum, and silicon, when present in concentrations of 100 ..mu..g/ml, enhance the beryllium signal. The addition of 100 ..mu..g/ml of lanthanum increases the signal over two fold and masks the signal enhancement caused by the other listed elements; however, hydrochloric and hydrofluoric acids still interfere. The recovery of 20 ng/ml of beryllium in the presence of 100 ..mu..g/ml of lanthanum and in the presence of 100 ..mu..g/ml each of thirty elements tested is 20 ..mu..g/ml with a relative standard deviation of 4 percent and a range of 19 to 22 ng/ml. The …

Sodium silicate glass microspheres in the 105-125 ..mu..m diameter size range, containing in vitreous solution the radioisotopes plutonium-238 and sodium-22, were prepared in four batches which emitted a nominal 40, 80, 320, and 640 nCi of total alpha radiation and approximately 1 nCi of gamma radiation form the sodium-22 isotope from each sphere. The initial integrity of the glasses was good and no wipeable contamination was detected from the spheres. The alpha particle range in the glass for the 5.5-MeV alpha particle emitted by plutonium-238 was calculated to be 15.2 ..mu..m, based upon radiometric analysis of individual spheres from each batch of product.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Phase distortion arising from whole beam self-focusing of intense laser pulses with arbitrary spatial profiles is treated in the limit of geometrical optics. The constant shape approximation is used to obtain the phase and angular distribution of the geometrical rays in the near field. Conditions for the validity of this approximation are discussed. Geometrical focusing of the aberrated beam is treated for the special case of a beam with axial symmetry. Equations are derived that show both the shift of the focus and the distortion of the intensity distribution that are caused by the nonlinear index of refraction of the optical medium. An illustrative example treats the case of beam distortion in a Nd:Glass amplifier.

At the present stage of reactor coolant studies it is possible to say that radiation affects the deposition behavior of corrosion products in the reactor. A quantitative relation between flux and deposition rate or amount is not available, nor is there information as to exactly which component, or combination thereof, of the radiation is most important. To determine these effects and those of other process parameters, Battelle-Northwest (BNW) is conducting an experimental program for the Knolls Atomic Power Laboratory (KAPL) to evaluate the behavior of corrosion products in pressurized, water-cooled nuclear reactor systems. This program is authorized by and is being performed under the terms and conditions of KAPL Purchase Order 7730-A (and Amendments).
