THE ELECTROMAGNETIC PINCH EFFECT FOR SPACE PROPULSION

Description: The phenomenon of the electromagnetic pinch effect is used to accelerate ionized gases for space propulsion. Electrical energy, initially stored in capacitors, is discharged across two nozzle shaped electrodes wherein the radial pinch is converted to axial motion of the effected gases instead of confinement at the axis. The gas dynamics of a pinch using the hydrodynamical model of a msgnetic piston driving a shock wave is combined with the electrodynamics of the circuit to calculate the dischar… more

Atmospheric Signals From Explosions and Their Interpretation

Description: Results are reported from a series of experimental highexplosive shots under inversion conditions at the Nevada Test Site which were made in an attempt to refine blast prediction techniques. Applications of the data in determinations of the amount of energy which remains in the blast wave as it reaches acoustic level and in determinations of the magnitude of the reflection factor when the blast wave strikes the ground are discussed. Data on shock wave propagation are presented graphically. It i… more

Ophthalmologic survey of atomic bomb survivors in Japan, 1949. Atomic bomb radiation cataract case report with histopathologic study. Medical examination of Hiroshima patients with radiation cataracts

Description: This document contains 3 reports dealing with the delayed effects of radiation on the eyes of survivors of the atomic explosions in Hiroshima and Nagasaki. In the first study, 1000 persons who were listed as having been in the open and within two kilometers of the hypocenter at the time of the explosion were selected at random from the census files of the Atomic Bomb Casualty Commission for study. In addition, 231 others, comprising the total available number of surviving persons listed at pres… more

Concentration of Plutonium by Cation Exchange--Stabilization of Pu(III) in Nitric Acid

Description: A study to define the effectiveness limits of sulfamic acid and to discover other better stabilizers for Pu(III) is described. Ascorbic and isoascorbic acids, used in conjunction with sulfamic acid reduced Pu(IV) to stable Pu(III) in nitric acid. Aminoguanidine sulfate also retarded the oxidation of Pu(III) but did not reduce Pu(IV). (J.R.D.)

REACTIVITY LIFETIME. TEST RESULTS DL-S-225(T-612118A). Section I, Second Performance

Description: The performance, reliability, stability, and reactivity lifetime variations of the Shippingport PWR are determined under normal steady state conditions. These characteristics are studied over a period of 758 EFPH, at a power level of about 60 Mw(e). Flux-tilt corrections and plant operations during this time are described. (T.F.H.)

An Experimental Evaluation of the Radiation Protection Afforded by a Large Modern Concrete Office Building

Description: Abstract: "An experimental study was made to determine the effective shielding provided by a modern reinforced-concrete office building (AEC Headquarters building) from nuclear fallout. Pocket ionization chambers were used for measurement of the radiation-field strength. Fallout was simulated with distributed and point-source configurations of Co-60 and Ir-192 sources. Four typical sections were selected for study, and experiments were performed on each. These included an external wing with exp… more

Blast biology: a study of the primary and tertiary effects of blast in open underground protective shelters. Project 33. 1 of Operation Plumbbob

Description: Dogs, pigs, rabbits, guinea pigs, and mice were exposed to nuclear detonations in two open underground partitioned shelters. The shelters were of similar construction, and each was exposed to separate detonations. Each inner chamber filled through its own orifice; thus four separate pressure environments were obtained. An aerodynamic mound was placed over the escape hatch of each structure to determine its effect on the pressure-curve shape inside the chamber. In one test a sieve plate bolted a… more

Production test IP-250-A irradiation of Zircaloy-2 jacketed tube-and-tube elements in the KER loops

Description: This report discusses testing three-foot Zircaloy-2 jacketed tube-and-tube elements with either natural or 1.6% enriched unalloyed or 2% zirconium alloyed uranium which will be irradiated in any of the KER Loops to goals up to 5000 WD/T. Downstream thermocouples to measure flow channel coolant temperatures will be included for charges of enriched elements. Special tray discharges to prevent the fall of the elements to the basin are required for all loadings. The tube-and-tube geometry is being … more

Relative Ball 3X-VSR reactivity strength DR reactor. Interim Report of PT IP-126-C

Description: Prior to this experiment, no measurements of Ball 3X effectiveness had been performed for any of the older 2004-tube Hanford piles, and calculations concerning total control requirements were made assuming the vertical safety system strength equal to the strength of the B, D, F vertical safety rods. With current and projected enrichment loadings, the vertical control system was calculated to be inadequate to satisfy the total control criteria at all times, resulting in the necessity to provide … more

KER Loop I operating report -- A report on the irradiation of zircaloy-2 jacketed tube-and-tube elements in KER Loop I

Description: The objective of this test was to determine the in-reactor performance of co-extruded Zr-2 jacketed tube-and-tube elements. The effect of power, surface temperature, and uranium alloying on dimensional stability and uranium swelling and cracking was to be measured. The charge consisted of two unalloyed tube-and-tube elements, which were Zr-2 jacketed and were 36 inches in length. The rest of the charge consisted of spacer material and coupon holders. The test started on 6-29-59 and ran for a pe… more

Physics considerations of old pile expansion study

Description: In view of the more-or-less eminent conversion of at least some of the older Hanford reactors to minimum process tubes it has been requested the feasibility and economics of increasing the process channel size by overboring be studied. This report is concerned with the feasibility from an operational physics standpoint of either raising reactor power levels with present aluminum process tubes and redesigned fuel elements raising reactor power levels with zirconium replacement tubes of current o… more

Improvements in the hot press process

Description: The hot press process has been altered so as to eliminate the slight wrinkling near the ID base. This was done by incorporating a three minute time delay in the pressing cycle. The pressing time was decreased to five minutes to restrict formation of the brittle intermetallic compound, Ni{sub 2}Al{sub 3}.

Post irradiation examination of a uranium swelling capsule, PT-IP-200-A (RM-257)

Description: A 1.6% enriched U rod was irradiated in 105 DR to 450 MWD/T, using a NaK-filled Al capsule. The capsule was discharged in November 1958 and examination begun. Results showed that the NaK in the capsule was trapped in the expansion chambers, leaving part of the fuel rod uncovered, causing gross heating on one side and failure of the rod, preventing the desired data from being obtained.
