Los Alamos ‘loses’ key weapons data

Los Alamos

The functionality of many materials of both fundamental and technological interest is often critically dependent on the nature andextentof any disorder that may be present. In addition, it is often difficult to understand the nature of disorder in quite well ordered systems. There is therefore an urgent need to develop better tools, both experimental and computational, for the study of such qua...

A Vadose Zone Flow and Transport Model for Los Alamos Canyon, Los Alamos, New Mexico

To gain an integrated understanding of flow and transport in the vadose zone and its role in transmitting conA vadose zone flow and transport model for Los Alamos Canyon tamination to the regional aquifer, conceptual flow and is presented that demonstrates that a comprehensive understanding transport models must be combined with site-specific of vadose zone hydrologic processes can be obtained ...

This paper reports single-processor performance of the DEC 8400 system, a multi-cpu mainframe based on the DEC 21164 microprocessor. Performance is compared with single processors of the CRAY J90, the IBM RISC System/6000 Model 39H, and the SGI Power Onyx (75 MHz MIPS R8000). Benchmark codes representing Los Alamos applications with a range of computational characteristics were used. An importa...

Waste Burial Site, Los Alamos National Laboratory

Small mammals were sampled at two waste burial sites (Sites 1 and 2) at Area G, TA-54, and a control site outside Area G (Site 3) to identify radionuclides that are present within surface and subsurface soils at waste burial sites, to compare the amount of radionuclide uptake by small mammals at waste burial sites to a control site, and to identify the primary mode of contamination to small mam...
