This test resulted in radionuclide-contaminated soils at Clean Slate I II and III. This report documents observations made during on-going monitoring of radiological meteorological and dust conditions at stations installed adjacent to Clean Slate I and Clean Slate III and at the TTR Range Operations Control center. The primary objective of the monitoring effort is to determine if winds blowing across the Clean Slate sites are transporting particles of radionuclide-contaminated soils beyond both the physical and administrative boundaries of the sites. Results for the calendar year (CY) 2013 monitoring include: (1) the gross alpha and gross beta values from the monitoring stations are approximately equivalent to the highest values observed during the CY2012 reporting at the surrounding Community Environmental Monitoring Program (CEMP) stations (this was the latest documented data available at the time of this writing) (2) only naturally occurring radionuclides were identified in the gamma spectral analyses (3) the ambient gamma radiation measurements indicate that the average annual gamma exposure is similar at all three monitoring stations and periodic intervals of increased gamma values appear to be associated with storm fronts passing through the area and (4) the concentrations of both resuspended dust and saltated sand particles generally increase with increasing wind speed. However differences in the observed dust concentrations are likely due to differences in the soil characteristics immediately adjacent to the monitoring stations. Neither the resuspended particulate radiological analyses nor the ambient gamma radiation measurements suggest wind transport of radionuclide-contaminated soils. |

Operation Roller Coaster consisted of four tests in which chemical explosions were detonated in the presence of nuclear devices to assess the dispersal of radionuclides and evaluate the effectiveness of storage structures to contain the ejected radionuclides. These tests resulted in the dispersal of plutonium over the ground surface downwind of the test ground zero (GZ). Three testsâClean Slate I II and IIIâwere conducted on the TTR in Cactus Flat. The fourth Double Tracks was conducted in Stonewall Flat on the NTTR. |

![](/C666/themes/default/image/downing1.png) 收藏  |  浏览/下载:8/0  |  提交时间:2019/04/05 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. |
