Technological hazards evaluation core E-Q load

Description: The United States Atomic Energy Commission authorized the production of 110 kg of U-233 by the irradiation of thorium oxide in the Hanford production reactors. This irradiation will be carried out by replacing the natural uranium fuel in all or a portion of the process tubes in several of the reactors with thorium oxide (thoria) and slightly enriched uranium. This reactor loading is referred to as an ``E-Q load.`` Reactor loadings are separated into two types which can be charged independently … more

Examination of four irradiated KVMS fuel elements - RM C-440

Description: Four KVNS production fuel elements which had operated for 66 days were submitted to the Radiometallurgy Laboratory for examination after being subjected to unusual conditions during shutdown. It was believed that the elements may have been at elevated temperatures for as long as 4-1/2 hours after shutdown. An abnormal film which appeared to be boiler scale was observed on some of the elements when they were examined in the basin immediately after discharge. Four elements were selected for metal… more

Modular Nuclear Testing Concept

Description: The continuing concern with efficient utilization of manpower at the Nevada Test Site (NTS) and the seemingly high cost of individual nuclear shots, together with the recent evolution of the L-12 scope, generated some fresh thoughts concerning more efficient procedures for the `average` test. Every time anyone looks at the problem., they tend to analyze the existing conventional approach and try to find the one or two most expensive and `lossy` factors in the can of worms. Usually this turns ou… more

Effects of gamma-ray irradiation on M1 propellant

Description: Samples of M1 single-base propellant were exposed to 10{sup 5}, 10{sup 6}, and 10{sup 7}r of Co{sup 60} gamma rays. Burning rates were determined over a pressure range of 600 to 2600 psi at -40{degrees}, 21{degrees}, and 71{degrees}C. A statistical study indicated no significant change in the burning rate and a small but statistically significant increase (6%) in the exponential factor n after the 10{sup 7}r dose. Visible deterioration resulted, as the color changed from yellow to dark brown an… more

Characteristics of H.E. and H.E. systems. Quarterly report, October--December, 1964

Description: Several samples of HMX to be used in LX-04-1 were particle sized and reported in this report. Most of the lots sized were very similar, with the major differences in the lots being at 2{micro}. Several counts in ``Rainbow`` Lot 26B of LX-04-1, made to obtain a color and weight distribution in several samples, and also a color count made in each sieve on a granulation analysis, show each color to be equally distributed; i.e., {approx} one-third of each color, green, yellow and white LX-04-1 gran… more

Physical properties of explosives. Quarterly report, January--March 1964

Description: This work is for the development of testing methods and determination of physical properties of H.E. formulations. An eight-cycle bulk compliance test on LX-04-1 produced a gain in density of 0.017 gm/cc from an average starting-density of 1.858 gm/cc, net gain of .810 gm/cc after one month storage. A group of tensile specimens were tested on three test machines in three locations (Baldwin at LRL, Instrom in Pantex Engineering and Tinius Olsen in Pantex Development), using specimens from a sing… more

Fulminant properties of high explosives equation of state studies. Quarterly report, January--March 1964

Description: This project consists of (1) essentially routine experimentation, including evaluation of detonation velocity, gap sensitivity testing, and drop weight-impact machine testing; and (2) an experimental program whose goal is the development of high precision one and two-dimensional hydrodynamic data for use in establishing empirical detonation product equations of state.

H.E. formulation. Quarterly report, July--September, 1964

Description: Emphasis was placed this quarter on the manufacture of extrudable explosives. This included the recrystallization of PETN which was used to manufacture two batches of LX-02-1 and one batch of RX-02-AK. The materials were examined for composition, extrudability and burning via detonation velocity. Also, a Sunburst and Sunray were performed on the first batch of LX-02 made. Results were all satisfactory except for detonation velocity; some of the channels were yielding somewhat erratic results wh… more

Time-to-explosion thermal initiation test for explosives

Description: A controlled series of experiments have been performed in an attempt to evaluate the Henkin time-to-explosion test as a reactivity test and a quality assurance tool. This was done by comparing the Henkin results with those obtained with the presently used gas chromatograph chemical reactivity test, Two explosives, PBX 9404 and LX-04-1, were tested with four ``inerts``: sodium chloride, lead powder, Silastic Q-300030 and epoxy 633111. The experimental data from the two tests are given; a method … more

Development of improved H.E. adhesive systems. Quarterly report for April--June, 1964

Description: A heat aging study in which tensile specimens (aluminum-to-aluminum and aluminum-to-LX-04-1 with Aerobond H-7) were heated to 165 F and aged up to three months has been completed. Aerobond H-7 showed no signs of deterioration when treated in this manner. Butyl glycidyl ether and benzene were tested as diluents for Aerobond H-7; butyl glycidyl ether is an effective diluent but benzene appeared to promote an exotherm. Water permeabilities were remeasured for Adiprene, Aerobond H-7, and Estane to … more

Characteristics of H.E. and H.E. systems. Quarterly report, July--September, 1964

Description: Data from sieve analyses of HMX and HMX recovered from LX-04-1 has been compiled for correlation to quality parameters. Particle size distributions on HMX received from LRL have been completed along with other HMX lots specified by them. Sieve analysis of recrystallized PETN was obtained using the now normal procedure for HMX. A statistical investigation of production LX-04-1 examined the dependence of density, elongation, and ultimate tensile strength on particle size distributions ({Pi}) and … more

Calculations on Cylindrical Metal Vacuum Chambers in Pulsed Magnetic Fields

Description: It has been suggested that metallic vacuum chambers might be suitable for pulsed magnets operating at audio frequencies, with pulse widths nominally 1/360 sec. In the present note calculations are given for a simple model of such a system, in order to estimate the effects of field attenuation and eddy current losses. The results of the calculation may be summarized briefly as follows, where the results apply to a cylindrical chamber of non-maeyletic stainless steel, 3.0 cm in inside diameter an… more

K Reactor moderator distortion study

Description: Irradiation-induced moderator distortion has plagued the Hanford reactors from their earliest days until the present. The first-manifestation of graphite distortion was in the form of expansion of the B, D and F stacks. It was found that expansion was very temperature-dependent and could be reversed by raising the graphite operating temperature. The DR, H, C and K Reactors were designed with provisions to minimize, or accommodate expansion. It was not until after the K Reactors had been designe… more
