Radioactive particles in the 234-5 Building ventilation exhaust

The 234-5 Building ventilation exhaust is continuously sampled for the purpose of estimating the amount of radioactive (alpha emitting) material discharged to the atmosphere. Although a record is kept of the gross amount of radioactive material discharged, few data are available concerning the size and kind of active particles in the exhaust air. Knowledge of the particle size permits: (1) an estimate of the validity of samples drawn through the sampling system, (2) a better knowledge of what t… more

A global overview of risk management of the DOE complex

No endeavor is risk-fire and as we realize the inherent risks in society, our only viable solution is to manage the risk. Application of an integrated risk management program of a large technological system like the DOE complex is a difficult, task; but it is the only rational means to optimize the risk-benefit equation. An effective risk management culture-within the DOE complex will in the long run, ensure a consistent response to mitigate identified risks. An effective risk management progra… more

Assessment of unsaturated zone radionuclide contamination in the 200 areas of the Hanford site, Washington

The 200 East and 200 West Areas at the Department of Energy`s Hanford site in southeastern Washington, contain chemical and nuclear fuel processing facilities that disposed of large volumes of chemical and radionuclide effluents to the ground via various structures such as ponds, cribs and ditches. A geophysical logging investigation was implemented in 1992 to assess the nature and extent of contamination beneath select liquid disposal sites in the 200 Areas. The borehole geophysical logging wa… more

Parametric design using IGRIP

The Department of Energy`s (DOE) Hanford site near Richland, Washington is being cleaned up after 50 years of nuclear materials production. One of the most serious problems at the site is the waste stored in single-shell underground storage tanks. There are 149 of these tanks containing the spent fuel residue remaining after the fuel is dissolved in acid and the desired materials (primarily plutonium and uranium) are separated out. The tanks are upright cylinders 75 ft. in diameter with domed t… more

Performance assessment of the Greater Confinement Disposal facility on the Nevada Test Site: Comparing the performance of two conceptual site models

A small amount of transuranic (TRU) waste has been disposed of at the Greater Confinement Disposal (GCD) site located on the Nevada Test Site`s (NTS) Radioactive Waste Management Site (RWMS). The waste has been buried in several deep (37 m) boreholes dug into the floor of an alluvial basin. For the waste to remain in its current configuration, the DOE must demonstrate compliance of the site with the TRU disposal requirements, 40 CFR 191. Sandia`s approach to process modelling in performance ass… more

CsI(Tl) with photodiodes for identifying subsurface radionuclide contamination

At the US Department of Energy`s Hanford Site near Richland, Washington, underground radioactive contamination exists as the result of leaks, spills, and intentional disposal of waste products from plutonium-production operations. Characterizing these contaminants in preparation for environmental remediation is a major effort now in progress. In this paper, a cylindrical (15 {times} 61 mm) CsI(Tl) scintillation detector with two side-mounted photodiodes has been developed to collect spectral ga… more

Sampling the contents of High-Level Waste tanks

Samples were recently retrieved from a HLW storage tank at the DOE Savannah River Site using simple tools developed for this task. The tools are inexpensive and manually operated, require brief tank open times, and minimize radiation doses.

Approach for systematic evaluation of transuranic waste management alternatives

This paper describes an approach for systematic evaluation of management alternatives that are being considered for the treatment, storage, and disposal of transuranic waste (TRUW) at U.S. Department of Energy sites. The approach, which is currently under development, would apply WASTE-MGMT, a database application model developed at Argonne National Laboratory, to estimate projected environmental releases and would evaluate impact measures such as health risk and costs associated with each of t… more

A chemical model for the major electrolyte components of the Hanford waste tanks. The binary electrolytes in the system: Na-NO{sub 3}-NO{sub 2}-SO{sub 4}-CO{sub 3}-F-PO{sub 4}-OH-AI(OH){sub 4}-H{sub 2}O

An aqueous thermodynamic model is developed, based on the equations of Pitzer, which accurately model the major binary electrolytes in the Na-NO{sub 3}-NO{sub 2}-SO{sub 4}-CO{sub 3}-F-PO{sub 4}-OH-Al(OH){sub 4}-H{sub 2}O chemical system. This model was developed both from existing data in the literature, and from new osmotic and solubility measurements made as part of this study. Some of the new experimental data developed as part of this study include measurements of osmotic coefficients for N… more

Criticality safety analysis of Hanford Waste Tank 241-101-SY

As part of a safety assessment for proposed pump mixing operations to mitigate episodic gas releases in Tank 241-101-SY at the Hanford Site, Richland, Washington, a criticality safety analysis was made using the Sn transport code ONEDANT. The tank contains approximately one million gallons of waste and an estimated 910 G of plutonium. the criticality analysis considers reconfiguration and underestimation of plutonium content. The results indicate that Tank SY-101 does not present a criticality … more

The U.S. Regulatory Framework for Long-Term Management of Uranium Mill Tailings

The US established the regulatory structure for the management, disposal, and long-term care of uranium mill tailings in 1978 with the passage of the Uranium Mill Tailings Radiation Control Act (UMTRCA) (Pub. L. 95-604). This legislation has governed the cleanup and disposal of uranium tailings at both inactive and active sites. The passage of the UMTRCA established a federal regulatory program for the cleanup and disposal of uranium mill tailings in the US. This program involves the DOE, the N… more

Introduced materials and colloid formation: A report on the current state of knowledge

This paper reviews potential sources of colloids and enhanced adsorption of radionuclides that may stem from materials introduced into a repository setting. Three major sources of colloids are examined: metals, cements, and organics. The sensitivity of colloids to chemical species, pH, time, temperature, radiolysis, redox state, gradients of the aforementioned variables, and microbial activity is shown. The authors consider these influences on colloid formation and sorption with respect to intr… more

Location and identification of radioactive waste in Massachusetts Bay

The accurate location and identification of hazardous waste materials dumped in the world`s oceans are becoming an increasing concern. For years, the oceans have been viewed as a convenient and economical place to dispose of all types of waste.

Savannah River Site disaggregated seismic spectra. (Based on WSRC-TR-93-102)

In the past, single enveloping response spectra have been used at the Savannah River Site (SRS) for seismic design and qualification purposes. This practice of generating simulated ground motions for use in design and qualification from a single spectrum now appears to be justified only when the total site seismic risk is the result of a single earthquake source or if site geology shapes the frequency content of the ground motion. If the data suggest that the occurrence of several earthquakes c… more
