Numerical analysis of thermal-hydrological conditions in thesingle heater test at Yucca Mountain

Description: The Single Heater Test (SHT) is one of two in-situ thermal tests included in the site characterization program for the potential underground nuclear waste repository at Yucca Mountain. The heating phase of the SHT started in August 1996, and was completed in May 1997 after 9 months of heating. The coupled processes in the unsaturated fractured rock mass around the heater were monitored by numerous sensors for thermal, hydrological, mechanical and chemical data. In addition to passive monitoring… more

LAB 3 Cleanroom Fan and Filters Analysis for the Supports

Description: A 1400 lb blower fan and a 2700 lb filter box are to be supported at Lab 3. The support structure is a framework that suspends from the building wall to the cleanroom and to a washroom. The framework is made of welded 4-inch x 8-inch x 1/4-inch rectangular A36 steel tube. Welds are to be standard prequalified welds as by AISC. The main support frame is approximately 7-feet off the floor and welded onto the top of 10 columns. A deflection and stress study was performed on the planned structure. … more

The Effects of Site Characterization Activities on the Abundance of Ravens (Corvus corax) in the Yucca Mountain Area

Description: In response to the Nuclear Waste Policy Act of 1982 and the Nuclear Waste Policy Amendments Act of 1987, the U.S. Department of Energy (DOE) developed and is implementing the Yucca Mountain Site Characterization Project. Raven abundance was measured from August 1991 through August 1995 along treatment and control routes to evaluate whether site characterization activities resulted in increased raven abundance at Yucca Mountain. This study fulfills the requirement set forth in the incidental tak… more

ICF quarterly report October-December 1998 volume 8, number 1

Description: This issue of the ICF Quarterly Report focuses on the final section of the 192-arm, 1.8-MJ National Ignition Facility (NIF). We describe both technological advances necessary for optimal utilization of the delivered energy and the hohlraum physics resulting from extremely high energy densities. Two articles belong to the first category. The conversion of infrared light to ultraviolet occurs at the tripler in the NIF's Final Optics Assembly. It is then necessary to separate any unconverted (firs… more

Logistic Regression Applied to Seismic Discrimination

Description: The usefulness of logistic discrimination was examined in an effort to learn how it performs in a regional seismic setting. Logistic discrimination provides an easily understood method, works with user-defined models and few assumptions about the population distributions, and handles both continuous and discrete data. Seismic event measurements from a data set compiled by Los Alamos National Laboratory (LANL) of Chinese events recorded at station WMQ were used in this demonstration study. PNNL … more
