Effective Specific Impulse of a Pulsed Rocket Engine

Description: The specific impulse achieved in a pulsed rocket engine augmented with a fissioning nuclear bomb could be greater than that of any continuous flow engine. To a certain extent, this increase in specific impulse would be obtained at the expense of motor weight and average thrust. This paper considers the first of these limitations, motor weight, and estimates the highest effective specific impulse to be expected from a nuclear-pulsed rocket motor with respect to the weight of the motor.

Fortran Program Kine: Calculating Kinematical and Dynamical Quantities for Particle Interactions and Decays

Description: FORTRAN program KINE is a calling routine for a collection of seven subroutines. Each subroutine calculates interesting kinematical and dynamical quantities for the particle reaction 1 + 2 {yields} 3 + 4 by applying special relativity to the process in the form of the Lorentz transformation. The reaction is completely specified if, in addition to the rest masses involved, two of the physical variables are specified. The subroutines perform calculations for the most useful combinations of these … more

Multipurpose scintillation camera

Description: The scintillation camera is a nonscanning instrument for displaying the distribution of radioactive isotopes. It can be used, for example, to show abnormalities in the thyroid gland with I-131, the size, shape and location of kidneys with Hg-203 Neohydrin or to locate brain tumors either with Hg-203 Neohydrin or with the new positron emitting agent, Ga-68 EDTA. For many applications, the scintillation camera has higher sensitivity than conventional isotope scanners, and will produce pictures in… more

Equation of State of Classical Systems of Charged Particles

Description: Recent developments in the classical theory of fully ionized gases and strong electrolyte solutions are reviewed, and are used to discuss the equation of state at high temperature and low densities. The pressure is calculated using the ring-integral approximation, and quantitative estimates of higher correction terms are given. The effect of short-range repulsive forces is shown by comparing the results with two kinds of potential functions: hard spheres of diameter a, and "soft" spheres for wh… more

Studies of Bismuth Alloys. Liquidus Curves of the Bi-Cu, Bi-Ag, and Bi-Au Systems

Description: The liquidus curves of the Bi-Cu, Bi-Ag, and Bi-Au systems were re- determined by means of a sampling method. The Bi-Ag curve,was somewhat shifted from the previously determined location. The eutectic was found at 262.5 {+-} 0.2{degrees}C at 4.95 {+-} 0.05 atom % silver (2.62 wt %). The Bi-Cu liquidus agreed fairly well with Kleppa's data over the range investigated by him. The discrepancies in the literature in regard to higher copper concentrations were resolved. The.eutectic was determined t… more

Evaluation of Some Integrals Arising in the Theory of Ionized Gases

Description: In some recent theories of the equation of state of classical ionized systems, the free energy depends on integrals of the form {integral}{sub 0}{sup {infinity}}[e{sup -{beta}V{sub s}}-1+{beta}V{sub s}-{beta}{sup 2}V{sub s}{sup 2}/2]r{sup 2}dr, where V{sub s} is a "screened" potential obtained from the real potential by summing certain infinite series of diagrams. This integral has been tabulated for V{sub s} appropriate to a potential {+-}(e{sup 2}/ r)(1 - e{sup -{gamma}r}). The equation of st… more

Proceedings of the Geophysical Laboratory - Lawrence Radiation Laboratory Cratering Symposium

Description: The geological papers in this morning's session will deal descriptively with surficial features and end products of impact craters caused by meteorite falls. Such items as breccia, structural deformation, normal and inverse stratigraphy, glass (fused rock), and coesite will frequently be mentioned. Meteor and explosion crater data are presented.

Studies of Bismuth Alloys. II. Distribution of Small Additions of Cu, Ag, OR Au between Solid and Liquid Phases in Bi-Cu, Bi-Ag, and Bi-Au

Description: The distribution of small amounts of radioactive Cu, Ag, and Au between precipitates of these elements and their solutions in bismuth was investigated at different temperatures by sampling the liquid. In all cases the . Doerner-Hoskins law was obeyed. Approximate distribution ratios were calculated and plotted against 1/T. Extrapolation to the melting temperature of the major component X in these Bi-X-Y systems yields values which compare well with the distribution constants obtained either fro… more

Prevention of a nuclear excursion upon water flooding of an ocean based Tory II-C

Description: As TORY II-C is presently designed, a nuclear excursion would occur if the core were flooded with water. This is true even if all of the existing control rods were fully inserted. Indeed ANGIE calculations indicate that the reactor would be about 30% super-critical in such a case. There are several methods by which the core may be forced sub- critical under these extreme conditions. We will here consider only the method of introducing, directly into the core, a material which strongly absorbs n… more

General chemistry technical note no. 61--new developments in plastic bonded explosives

Description: Two new explosives are under development at Lawrence Radiation Laboratory (LRL) which show considerable promise as replacements for PBX 9404 (and also PBX 9010). Three primary considerations have guided us in the development of these explosives. Compared to PBX 9404 we have sought a significant decrease it sensitivity, a substantial gain in mechanical properties and as little loss in energy and detonation velocity as possible. While testing is not complete on these materials and probably won`t … more

Porosity gain from increase in core radius and fuel mass in Tory II-C

Description: A set of calculations has been done to determine the amount by which the volume of solid material in a Tory II-C core can be reduced with respect to the total core volume. Three separate problems were studied. In each case, some change was made which by itself would increase the K[sub eff] of the reactor. Then, in order to keep K[sub eff] unchanged, a certain amount of core material was removed. The calculations were done by means of the one-dimensional neutronic diffusion code ZOOM. The base p… more

Annual Report to Congress 1966

Description: Progress in the Plowshare program during 1966 was characterized by the upsurge of interest by industry in the contained applications of nuclear explosions for gas and oil stimulation, storage and disposal, recovery of oil from oil shales, and mining. Advances in the excavation area were limited to improved code calculations as no field experiments were conducted.

Joint Chiefs of Staff: Notes

Description: The purpose of the paper is to state the rationale upon which the Joint Chiefs of Staff (JCS) bases its opposition to further extension of the Limited Test Ban Treaty (LTBT). The argumentation of the paper is hinged primarily on the contention that the USSR is ahead of the US in nuclear weapon technology. Accordingly, there is much for the US to do, so that the Soviets do not, primarily through the deployment of an Anti-Ballistic Missile [ABM] system, alter the strategic balanc the US should no… more
