3-megajoule heavy-ion fusion driver

Description: The initiation of inertial confinement fusion reactions with a heavy ion particle beam has been under intensive study since 1976, and the progress of this study is principally documented in the proceedings of annual workshops held by US National Laboratories. At this time a 3MJ, 150 TW, ion beam is a good choice to initiate microexplosions with energy gain of 100. The Lawrence Berkeley Laboratory has made systems studies based on a Linear Induction Accelerator to meet the beam requirements. The… more

Absorption spectrophotometric characterization of Sm(II), Sm(III), and Sm(II/III) bromides and Sm(III) oxybromide in the solid state

Description: Absorption spectra obtained from SmBr/sub 3/, SmBr/sub 2/, and Sm0Br were used in identifying the samarium species in several mixed-valence Sm(II/III) compounds produced by H/sub 2/ reduction of SmBr/sub 3/. The nature of the absorption of Sm0Br made it possible to detect even traces of Sm0Br in the Sm bromides.

ACDOS2: an improved neutron-induced dose rate code

Description: To calculate the expected dose rate from fusion reactors as a function of geometry, composition, and time after shutdown a computer code, ACDOS2, was written, which utilizes up-to-date libraries of cross-sections and radioisotope decay data. ACDOS2 is in ANSI FORTRAN IV, in order to make it readily adaptable elsewhere.

Airborne and field-temperature surveys compared at Long Valley KGRA, California

Description: An airborne predawn radiometric temperature survey was flown over the Long Valley KGRA. Radiometric temperatures were recorded at 10 to 12 ..mu..m and 4.5 to 5.5 ..mu..m. They were corrected to obtain true land-surface temperatures in agreement with field data. After accounting for thermal effects from surface features, there remained a thermal anomaly. The anomalous zone encompassed 2 km/sup 2/. It was a dry land area with a predawn surface temperature which averaged 1.4 +- 0.3/sup 0/C warmer … more

Alpha-spectroscopic techniques for field measurement of radon daughters

Description: Alpha spectroscopic techniques have not often been used to measure radon daughter concentrations in field studies because the equipment required is bulky and expensive. With advances in integrated circuit technology, less expensive, portable instruments have been developed that now make it possible to use these techniques to measure the low concentrations of radon daughters typically found indoors. One of two procedures may be used, two-count or single-count, depending on whether precision of m… more

Alternatives for reducing hot-water bills

Description: A two stage approach to reducing residential water heating bills is described. In Stage I, simple conservation measures were included to reduce the daily hot water energy consumption and the energy losses from the water tank. Once these savings are achieved, Stage II considers more costly options for further reducing the water heating bill. Four alternatives are considered in Stage II: gas water heaters; solar water heaters (two types); heat pump water heaters; and heat recovery from a heat pum… more

Alternatives to proposed replacement production reactors

Description: To insure adequate supplies of plutonium and tritium for defense purposes, an independent evaluation was made by Los Alamos National Laboratory of the numerous alternatives to the proposed replacement production reactors (RPR). This effort concentrated on the defense fuel cycle operation and its technical implications in identifying the principal alternatives for the 1990s. The primary options were identified as (1) existing commercial reactors, (2) existing and planned government-owned facilit… more

Analysis of the mine-by experiment, climax granite, Nevada test site

Description: The Lawrence Livermore National Laboratory (LLNL) is conducting a generic test of retrievable geologic storage of nuclear spent fuel assemlbies, in an underground chamber, at the Nevada Test Site, Nye County, Nevada. This generic test is located 420 m below the surface, in the Climax granitic stock.

Analysis, scale modeling, and full-scale test of a railcar and spent-nuclear-fuel shipping cask in a high-velocity impact against a rigid barrier

Description: This report describes the mathematical analysis, the physical scale modeling, and a full-scale crash test of a railcar spent-nuclear-fuel shipping system. The mathematical analysis utilized a lumped-parameter model to predict the structural response of the railcar and the shipping cask. The physical scale modeling analysis consisted of two crash tests that used 1/8-scale models to assess railcar and shipping cask damage. The full-scale crash test, conducted with retired railcar equipment, was c… more

Analytic flux formulas and tables of shielding functions

Description: Hand calculations of radiation flux and dose rates are often useful in evaluating radiation shielding and in determining the scope of a problem. The flux formulas appropriate to such calculations are almost always based on the point kernel and allow for at most the consideration of laminar slab shields. These formulas often require access to tables of values of integral functions for effective use. Flux formulas and function tables appropriate to calculations involving homogeneous source region… more

Annual progress report

Description: Emphasis during the past year has been on studies of the effects of potential promoting agents on radiation transformation, and of transformation by internal radionuclides emitting high LET radiation. We have also carried out a detailed investigation of the dosimetry of our alpha radiation source. Preliminary studies on the mechanisms of radiation transformation have been initiated as described in the previous proposal. Studies on promotion have focused on the effects of: (1) the endogenous ste… more

Application of the J Integral to Fracture Under Mixed-Mode Loading

Description: The calculation of the J integral proved to be a successful method for characterizing the stress and displacement fields around a crack tip under mixed mode loading. A computer program was written to determine the symmetric and antisymmetric J integral quantities. The stress intensity factors from these J integral calculations were in excellent agreement with other calculations. The compact shear specimen used contains three loading holes, the load applied at the center hole being the opposite … more

Description: A comparative analysis of solar thermal concepts that are potentially suitable for development as large process heat systems (50 to 600 MWt) was performed. The concepts considered can be classified into three categories based on the type of solar tracking used by the collector: (1) two-axis tracking, in which concentrators track the sun's motion in both azimuth and altitude; (2) one-axis tracking, in which concentrators track changes in either azimuth or altitude; and (3) non-tracking, in which… more

Assessment of Precise Surface-Gravity Measurements for Monitoring the Response of a Geothermal Reservoir to Exploitation

Description: Recommendations for carrying out surveys which achieve 15, 10 and 5 microgal precisions are presented. Achieving the smaller standard deviations will require more field effort and will be more costly. For a 60 station survey, at commercial rates in 1981, typical costs are estimated to be $20,000, $26,000 and $35,000 respectively, for data collection, reduction and interpretation. These figures exclude instrument purchase or rental. Twenty geothermal areas in the western United States which migh… more
