Abstract:This paper presents selected results obtained during the 301 day duration of the Prototype Engineered Barrier System Field Test (PEBSFT) performed in G-Tunnel within the Nevada Test Site. The test described is a precursor to the Engineered Barrier Systems Field Tests (EBSFT) planned forlhe Exploratory Shaft Facility in Yucca Mountain. The EBSFT will consist of in situ tests of the geohydrologic and geochemical environment in the near field (within a few meters) of heaters emplaced in welded tuff to simulate th… Show more
“…• For the PEBSFT Ramirez et al, 1989 and1991b), moisture redistribution was observed using several boreholes spaced as closely as 0.5 m; the maximum radius of the dryout zone was determined to be approximately 0.7 m. The configuration of the dryout zone was circular and shifted downward relative to the heater axis. Evidence for shedding of condensate to the sides of the heater was observed.…”

“…Heater tests in G-Tunnel at Ranier Mesa were performed by several investigators including Johnstone et al (1985) and Ramirez et al (1990). In at least one of those tests, thermally induced water movement was evidenced by water accumulation in the heater holes.…”
Hydrothermal systems in tuffaceous and older sedimentary rocks contain evidence of the interaction of radionuclides in fluids with rock matrix minerals and with materials lining fractures, In settings
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
