Bomb-Pulse Chlorine-36 At The Proposed Yucca Mountain Repository Horizon: An Investigation Of Previous Conflicting Results And Collection Of New Data, Klaus J. Stetzenbach, Fred Phillips, Drew Coleman, Don Baepler, Amy J. Smiecinski

Previous studies by scientists at Los Alamos National Laboratory (LANL) and the United States Geological Survey (USGS) quantified 36Cl/Cl to test for the presence of fast pathways at the proposed Yucca Mountain high-level nuclear waste repository. The goal of these studies was to determine whether or not fluids containing bomb-pulse 36Cl/Cl traveled along fast travel pathways and reached the repository horizon, however, the two groups followed somewhat different procedures and produced conflicting results. The objective of this study is to attempt to determine the cause of the conflicting results and to obtain additional data to determine whether or …


Precipitation Monitoring At Yucca Mountain From 10/01/2000 Through 06/30/2003, Amanda Brandt, Klaus J. Stetzenbach, Amy J. Smiecinski Nov 2003

Precipitation Monitoring At Yucca Mountain From 10/01/2000 Through 06/30/2003, Amanda Brandt, Klaus J. Stetzenbach, Amy J. Smiecinski

This report presents precipitation data collected using tipping bucket rain gauges in the vicinity of Yucca Mountain from October 1, 2000 to June 30, 2003. Operation of the tipping bucket precipitation monitoring network was assumed by the Harry Reid Center for Environmental Studies at University of Nevada, Las Vegas in March 2001. Previously, it had been operated by the U.S. Geological Survey. The precipitation monitoring network consists of 17 tipping bucket gauges at various locations in the vicinity of Yucca Mountain. During the 2001 water year, rainfall averaged 6.16 inches. The following 2002 water year was much drier averaging 1.11 …


Identification Of Dynamic Properties Of Materials For The Nuclear Waste Package, Brendan O'Toole, Mohamed Trabia, Amy J. Smiecinski Oct 2003

Identification Of Dynamic Properties Of Materials For The Nuclear Waste Package, Brendan O'Toole, Mohamed Trabia, Amy J. Smiecinski

Stainless steel 316L, titanium alloy grade 7, and alloy C22 are currently under consideration as candidate materials for use in various components associated with the spent nuclear fuel package, which must be designed to withstand structural deformation caused by static, thermal, and handling loads. In addition, it has to maintain its integrity in case of accidents, where it may be subjected to high loads over a very short period of time. Mechanical characteristics of these three materials under dynamic loading are not well documented. This paper describes the procedures and results obtained from experiments performed over a range of slow …


Ground Water Level Measurements In Selected Boreholes Near The Site Of The Proposed Repository, H. Scott Page, Klaus J. Stetzenbach, Amy J. Smiecinski Oct 2003

Ground Water Level Measurements In Selected Boreholes Near The Site Of The Proposed Repository, H. Scott Page, Klaus J. Stetzenbach, Amy J. Smiecinski

Analysis of twenty years of ground water level monitoring data by the Department of Energy on the boreholes comprising the periodic network near Yucca Mountain indicate that overall, such levels have been remarkably stable. Continuing this program of longterm monitoring, the Harry Reid Center for Environmental Studies at the University of Nevada - Las Vegas (HRC) has acquired quarterly data on water levels from the same network between July 2001 and June 2003. Analysis of selected 2002 quarterly ground water level data collected by the HRC using manual and electronic techniques on boreholes in the volcanic flow system aquifer appears …
