Characterization Plan for the Old Hydrofracture Facility

Description: US Department of Energy (DOE) facilities are required to comply fully with all federal and state regulations. In response to this requirement, the Oak Ridge National Laboratory (ORNL) has established the remedial action program, to provide comprehensive management of areas where past research, development, and waste management activities have been conducted and have resulted in residual contamination of facilities or the environment. One of the objectives of this program is to define the extent… more

EARTHSAWtm IN-SITU CONTAINMENT OF PITS AND TRENCHES

Description: EarthSaw{trademark} is a proposed technology for construction of uniform high quality barriers under and around pits and trenches containing buried radioactive waste without excavating or disturbing the waste. The method works by digging a deep vertical trench around the perimeter of a site, filling that trench with high specific gravity grout sealant, and then cutting a horizontal bottom pathway at the base of the trench with a simple cable saw mechanism. The severed block of earth becomes buo… more

AX Tank Farm tank removal study

Description: This report examines the feasibility of remediating ancillary equipment associated with the 241-AX Tank Farm at the Hanford Site. Ancillary equipment includes surface structures and equipment, process waste piping, ventilation components, wells, and pits, boxes, sumps, and tanks used to make waste transfers to/from the AX tanks and adjoining tank farms. Two remedial alternatives are considered: (1) excavation and removal of all ancillary equipment items, and (2) in-situ stabilization by grout f… more

Toxicity assessment of Hanford Site wastes by bacterial bioluminescence. [Photobacter phosphoreum:a3]

Description: This paper examines the toxicity of the nonradioactive component of low-level wastes stored in tanks on the Hanford reservation. The use of a faster, cheaper bioassay to replace the 96 hour fish acute toxicity test is examined. The new bioassay is based on loss of bioluminescence of {und Photobacter phosphoreum} (commonly called Microtox) following exposure to toxic materials. This bioassay is calibrated and compares well to the standard fish acute toxicity test for characterization of Hanford … more

Laboratory Evaluation of Underwater Grouting of CPP-603 Basins

Description: A project is underway to deactivate a Fuel Storage Basin. The project specifies the requirements and identifies the tasks that will be performed for deactivation of the CPP- 603 building at the Idaho Nuclear Technology and Engineering Center of the Idaho National Engineering and Environmental Laboratory. The Fuel Receiving and Storage Building (CPP- 603) was originally used to receive and store spent nuclear fuel from various facilities. The area to undergo deactivation includes the three spent… more

Ion Recognition Approach to Volume Reduction of Alkaline Tank Waste by Separation of Sodium Salts

Description: The overall goal of this research conducted under the auspices of the USDOE Environmental Management Science Program (EMSP) is to provide a scientific foundation upon which the feasibility of new liquid-liquid extraction chemistry applicable to the bulk reduction of the volume of tank waste can be evaluated. Disposal of high-level nuclear waste is horrendously expensive, in large part because the actual radioactive matter in the tanks has been diluted over 10,000-fold by ordinary inorganic chem… more

Flow of cavity gas along fractures, cable bundles, and grouted cables

Description: Analytical and numerical solutions are presented for gas flow along isolated fractures in permeable media. Two different cases are considered: preexisting fractures with a uniform aperture, as well as hydraulically-driven fractures with a variable aperture which is proportional to the local overpressure (local fluid pressure less confining stress). Results for these two geometries are compared with one another and with results for wedge-shaped and penny-shaped fracture geometries. Application t… more

Polyethylene encapsulation of single-shell tank low-level wastes

Description: This report describes work supported by the UST-ID, conducted at Brookhaven National Laboratory I (BNL), to develop and demonstrate a polyethylene waste encapsulation process for low-level radioactive (LLW) and hazardous mixed wastes (HMW) stored in underground tanks. During FY 1992, studies were completed on the effects of elevated temperature on waste form integrity, strength and leachability. No changes in waste form integrity or compressive yield strength were detected after storing polyeth… more

Bell Canyon Test (BCT) cement grout development report

Description: Development of the cement grout for the Bell Canyon Test was accomplished at the US Army Engineer Waterways Experiment Station (WES), Vicksburg, Mississippi. Initial development work centered on a saltwater grout with Class H cement, fly ash, and an expansive additive. Testing of the saltwater grout showed suitable properties except for the interface between anhydrite rock and grout in small core samples. Higher than expected permeability occurred at the interface because of space between the g… more

Borehole plugging materials development program, report 2

Description: The data for 2 yr of grout mixtures durability studies developed for the borehole plugging program of the Nuclear Waste Isolation Pilot Plant (WIPP) are reported. In addition, data for 1 yr of durability studies of grout mixture field samples used to plug the ERDA No. 10 exploratory drill hole near the WIPP site are included. The grout samples and the data do not show any evidence of deterioration during the durability studies that include exposure to brine at both ambient and elevated temperat… more

Bell Canyon Test (BCT): cement development report

Description: The Borehole Plugging (BHP) materials development program which has been underway at WES under Sandia sponsorship for about five years is reviewed. Development testing data for candidate grout mixtures for the BCT plug are presented. Field batching, mixing, and placement operations are discussed. Data from field samples molded during the two plug placements include strength, expansion, compressional wave velocity, dynamic modulus, density, and porosity. Microstructure and composition are compar… more

SRS tank closure. Innovative technology summary report

Description: High-level waste (HLW) tank closure technology is designed to stabilize any remaining radionuclides and hazardous constituents left in a tank after bulk waste removal. Two Savannah River Site (SRS) HLW tanks were closed after cleansing and then filling each tank with three layers of grout. The first layer consists of a chemically reducing grout. The fill material has chemical properties that retard the movement of some radionuclides and chemical constituents. A layer of controlled low-strength … more

Integrated process analyses studies on mixed low level and transuranic wastes. Summary report

Description: Options for integrated thermal and nonthermal treatment systems for mixed low-level waste (MLLW) are compared such as total life cycle cost (TLCC), cost sensitivities, risk, energy requirements, final waste volume, and aqueous and gaseous effluents. The comparisons were derived by requiring all conceptual systems to treat the same composition of waste with the same operating efficiency. Thus, results can be used as a general guideline for the selection of treatment and disposal concepts. Howeve… more
