The U.S. Department of Energy (DOE)
National Nuclear Security Administration
Nevada Field Office (NNSA/NFO) is currently working to achieve regulatory closure of radionuclide-contaminated Soils sites under its auspices. Corrective Action Unit (CAU) 415
Project 57 No. 1 Plutonium Dispersion Site is located in Emigrant Valley
Nevada
on Range 4808A of the Nevada Test and Training Range (NTTR)
and consists of one Corrective Action Site (CAS): NAFR-23-02
Pu Contaminated Soil. Closure plans being developed for the CAUs both on and off of the Nevada National Security Site (NNSS) may include postclosure monitoring for the possible release of radioactive contaminants. Determining the potential for transport of radionuclide-contaminated soils under ambient climatic conditions will facilitate an appropriate closure design and postclosure monitoring program. The DOE has authorized the Desert Research Institute (DRI) to conduct field assessments of potential transport of radionuclide-contaminated soil from the Project 57 site during ambient wind events. The assessment is intended to provide site-specific information on meteorological conditions that result in airborne soil particle redistribution
as well as determine which
if any
radiological contaminants may be entrained with the soil particles and estimate their concentrations.

Due to the legacy of Cold War nuclear weapons testing
the Nevada National Security Site (NNSS
formerly known as the Nevada Test Site (NTS)) contains millions of Curies of radioactive contamination. Presented here is a summary of the results of the first comprehensive study of subsurface microbial communities of radioactive and nonradioactive aquifers at this site. To achieve the objectives of this project
cooperative actions between the Desert Research Institute (DRI)
the Nevada Field Office of the National Nuclear Security Administration (NNSA)
the Underground Test Area Activity (UGTA)
and contractors such as Navarro-Interra (NI)
were required. Ultimately
fluids from 17 boreholes and two water-filled tunnels were sampled (sometimes on multiple occasions and from multiple depths) from the NNSS
the adjacent Nevada Test and Training Range (NTTR)
and a reference hole in the Amargosa Valley near Death Valley. The sites sampled ranged from highly-radioactive nuclear device test cavities to uncontaminated perched and regional aquifers. Specific areas sampled included recharge
intermediate
and discharge zones of a 100
000-km2 internally-draining province
known as the Death Valley Regional Flow System (DVRFS)
which encompasses the entirety of the NNSS/NTTR and surrounding areas. Specific geological features sampled included: West Pahute and Ranier Mesas (recharge zone)
Yucca and Frenchman Flats (transitional zone)
and the Western edge of the Amargosa Valley near Death Valley (discharge zone). The original overarching question underlying the proposal supporting this work was stated as: Can radiochemically-produced substrates support indigenous microbial communities and subsequently stimulate biocolloid formation that can affect radionuclides in NNSS subsurface nuclear test/detonation sites? Radioactive and non-radioactive groundwater samples were thus characterized for physical parameters
aqueous geochemistry
and microbial communities using both DNA- and cultivation-based tools in an effort to understand the drivers of microbial community structure (including radioactivity) and microbial interactions with select radionuclides and other factors across the range of habitats surveyed.

This report presents a historical evaluation of the U15 Complex on the Nevada National Security Site (NNSS) in southern Nevada. The work was conducted by the Desert Research Institute at the request of the U.S. Department of Energy
National Nuclear Security Administration Nevada Field Office and the U.S. Department of Defense
Defense Threat Reduction Agency. Three underground nuclear tests and two underground nuclear fuel storage experiments were conducted at the complex. The nuclear tests were Hard Hat in 1962
Tiny Tot in 1965
and Pile Driver in 1966. The Hard Hat and Pile Driver nuclear tests involved different types of experiment sections in test drifts at various distances from the explosion in order to determine which sections could best survive in order to design underground command centers. The Tiny Tot nuclear test involved an underground cavity in which the nuclear test was executed. It also provided data in designing underground structures and facilities to withstand a nuclear attack. The underground nuclear fuel storage experiments were Heater Test 1 from 1977 to 1978 and Spent Fuel Test - Climax from 1978 to 1985. Heater Test 1 was used to design the later Spent Fuel Test - Climax experiment. The latter experiment was a model of a larger underground storage facility and primarily involved recording the conditions of the spent fuel and the surrounding granite medium. Fieldwork was performed intermittently in the summers of 2011 and 2013
totaling 17 days. Access to the underground tunnel complex is sealed and unavailable. Restricted to the surface
four buildings
four structures
and 92 features associated with nuclear testing and fuel storage experiment activities at the U15 Complex have been recorded. Most of these are along the west side of the complex and next to the primary access road and are characteristic of an industrial mining site
albeit one with scientific interests. The geomorphological fieldwork was conducted over three days in the summer of 2011. It was discovered that major modifications to the terrain have resulted from four principal activities. These are road construction and maintenance
mining activities related to development of the tunnel complex
site preparation for activities related to the tests and experiments
and construction of drill pads and retention ponds. Six large trenches for exploring across the Boundary geologic fault are also present. The U15 Complex
designated historic district 143 and site 26NY15177
is eligible to the National Register of Historic Places under Criteria A
C
and D of 36 CFR Part 60.4. As a historic district and archaeological site eligible to the National Register of Historic Places
the Desert Research Institute recommends that the area defined for the U15 Complex
historic district 143 and site 26NY15117
be left in place in its current condition. The U15 Complex should also be included in the NNSS cultural resources monitoring program and monitored for disturbances or alterations.
