324 and 325 Building hot cell cleanout program: Decontamination of C-Cell

During FY 1989 the decontamination of C-Cell of Hanford's 324 Building was completed as part of the 324 and 325 Building Hot Cell Cleanout Program sponsored by the DOE Nuclear Energy's Surplus Facilities Management Program. The decontamination effort was completed using a series of remote and contact decontamination techniques. Initial radiation readings in C-Cell averaged 50 rad/hr and were reduced remotely to less than 200 mrad/hr using an alkaline foam cleaner followed by a 5000-psi water fl… more

1980 Environmental monitoring report: US Department of Energy Facilities, Grand Junction, Colorado, and Monticello, Utah

The effect the Grand Junction, Colorado and Monticello, Utah facilities have on the environment is reflected by the analyses of air, water, and sediment samples. The off-site water and sediment samples were taken to determine what effect the tailings and contaminated equipment buried on the sites may have on the air, water, and adjacent properties.

Addressing data heterogeneity: Lessons learned from a multimedia risk assessment

Cleanup activities are currently being conducted by the US Department of Energy (DOE) at a former chemical plant site that has been inactive for more than 20 years. The Army produced nitroaromatic explosives at the 220-acre site during the 1940s, and radioactive materials of the uranium and thorium series were processed there by DOE's predecessor agency during the 1950s and 1960s. Chemical and radioactive contaminants are present in soil, surface water, sediment, and groundwater at the site as … more

Allowable Residual-Contamination Levels for Decommissioning Facilities in the 100 Areas of the Hanford Site

This report contains the results of a study sponsored by UNC Nuclear Industries to determine Allowable Residual Contamination Levels (ARCL) for five generic categories of facilities in the 100 Areas of the Hanford Site. The purpose of this study is to provide ARCL data useful to UNC engineers in conducting safety and cost comparisons for decommissioning alternatives. The ARCL results are based on a scenario/exposure-pathway analysis and compliance with an annual dose limit for three specific mo… more

Alternatives for management of wastes generated by the formerly utilized sites remedial action program and supplement

Alternatives for disposal or stabilization of the wastes generated by the US Department of Energy's Formerly Utilized Sites Remedial Action Program (FUSRAP) are identified and compared, with emphasis on the long-term aspects. These wastes consist of soil material and rubble containing trace amounts of radionuclides. A detailed pathway analysis for the dose to the maximally exposed individual is carried out using an adaptation of the natural analogue method. Comparisons of the different alternat… more

Analysis of cobbly soils for cobbles-to-fines corrections to radionuclide concentrations at the New Rifle, Colorado, processing site

A contamination depth and cobbly soil characterization study was performed in November and December 1993 at the Uranium Mill Tailings Remedial Action (UMTRA) Projects`s New Rifle, Colorado, processing site. This study was initiated due to a concurrence by the US Nuclear Regulatory Commission (NRC) clarifying that the allowable residual contamination in soil should be averaged over the total mass of the soil volume, including cobbles and gravels (i.e., bulk concentration). The New Rifle processi… more

An automatic locating and data logging system for radiological walkover surveys

Oak Ridge National Laboratory has developed an Ultrasonic Ranging and Data System (USRADS) to track a radiation surveyor in the field, to log his instrument's reading automatically, and to provide tabular and graphical data display in the field or in the office. Once each second, USRADS computes the position of the radiation surveyor by using the time-of-flight of an ultrasonic chirp, emitted by a transducer carried in a backpack, to stationary receivers deployed in the field. When the ultrason… more
