Quantitative assessment of microbiological contributions to corrosion of candidate nuclear waste-package materials

The U.S. Department of Energy is contributing to the design of a potential nuclear-waste repository at Yucca Mountain, Nevada. A system to predict the contribution of Yucca Mountain (YM) bacteria to overall corrosion rates of candidate waste-package (WP) materials was designed and implemented. DC linear polarization resistance techniques were applied to candidate material coupons that had been inoculated with a mixture of YM-derived bacteria with potentially corrosive activities or left sterile… more

Production reactor disposal on the Hanford site

One of the many restoration challenges for the Hanford Site is the disposal of eight plutonium production reactors inactive since 1971. In order to minimize environmental and public health and safety impacts disposal alternatives were evaluated in an Environmental Impact Statement (EIS). Alternatives considered were no action, immediate one-piece removal, safe storage followed by deferred one- piece removal, safe storage followed by deferred dismantlement, and in-situ decommissioning. Evaluatio… more

Designing Reactors to Facilitate Decommissioning

Critics of nuclear power often cite issues with tail-end-of-the-fuel-cycle activities as reasons to oppose the building of new reactors. In fact, waste disposal and the decommissioning of large nuclear reactors have proven more challenging than anticipated. In the early days of the nuclear power industry the design and operation of various reactor systems was given a great deal of attention. Little effort, however, was expended on end-of-the-cycle activities, such as decommissioning and disposa… more

NPR liquid radioactive waste

A request was made for the re-examination of the sources of radioactive liquid waste arising from operation of the New Production Reactor. Concern was expressed about the routine discharge of certain waste streams and their relationship to the Columbia River. This letter discusses the background and the criteria upon which the present NPR radioactive waste disposal practices are based. It also states the anticipated quantities of radioactive material, their release to the environs, and compares… more

Siting Study for the Remote-Handled Low-Level Waste Disposal Project

The U.S. Department of Energy has identified a mission need for continued disposal capacity for remote-handled low-level waste (LLW) generated at the Idaho National Laboratory (INL). An alternatives analysis that was conducted to evaluate strategies to achieve this mission need identified two broad options for disposal of INL generated remote-handled LLW: (1) offsite disposal and (2) onsite disposal. The purpose of this study is to identify candidate sites or locations within INL boundaries for… more

Disposition of nuclear waste using subcritical accelerator-driven systems

Studies have shown that the repository long-term radiological risk is from the long-lived transuranics and the fission products Tc-99 and I-129, thermal loading concerns arise mainly form the short-lived fission products Sr-90 and Cs-137. In relation to the disposition of nuclear waste, ATW is expected to accomplish the following: (1) destroy over 99.9% of the actinides; (2) destroy over 99.9% of the Tc and I; (3) separate Sr and Cs (short half-life isotopes); (4) separate uranium; (5) produce … more

Feasibility survey: Krypton removal at Hanford

Fission-production of krypton-85 in natural uranium piles is substantial and in direct proportion to plutonium production. The known chemical and nuclear properties of krypton are such as to permit its determination in air samples taken at considerable distance from its force and to allow correlation of such measurements with plutonium production.

Alternate form and placement of short lived reactor waste and associated fuel hardware for decommissioning of EBR-II

Upon the termination of EBR-II operation in 1994, the mission has progressed to decommissioning and waste cleanup of the facility. The simplest method to achieve this goal is to bury the raw fuel and activated steel in an approved burial ground or deep geologic repository. While this might be simple, it could be very expensive, consume much needed burial space for other materials, and leave large amounts of fissile easily available to future generations. Also, as with any operation, an associat… more

Acceptance criteria for interim dry storage of aluminum-clad fuels

Direct repository disposal of foreign and domestic research reactor fuels owned by the United States Department of Energy is an alternative to reprocessing (together with vitrification of the high level waste and storage in an engineered barrier) for ultimate disposition. Neither the storage systems nor the requirements and specifications for acceptable forms for direct repository disposal have been developed; therefore, an interim storage strategy is needed to safely store these fuels. Dry sto… more

Spent fuel treatment and mineral waste form development at Argonne National Laboratory-West

At Argonne National Laboratory-West (ANL-West) there are several thousand kilograms of metallic spent nuclear fuel containing bond sodium. This fuel will be treated in the Fuel Conditioning Facility (FCF) at ANL-West to produce stable waste forms for storage and disposal. Both mineral and metal high-level waste forms will be produced. The mineral waste form will contain the active metal fission products and the transuranics. Cold small-scale waste form testing has been on-going at Argonne in Il… more

Report on waste burial charges: Escalation of decommissioning waste disposal costs at Low-Level Waste Burial facilities. Revision 5

One of the requirements placed upon nuclear power reactor licensees by the US Nuclear Regulatory Commission (NRC) is for the licensees to periodically adjust the estimate of the cost of decommissioning their plants, in dollars of the current year, as part of the process to provide reasonable assurance that adequate funds for decommissioning will be available when needed. This report, which is scheduled to be revised periodically, contains the development of a formula for escalating decommission… more

Determination of the theoretical feasibility for the transmutation of europium isotopes from high flux isotope reactor control cylinders

The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) is a 100 MWth light-water research reactor designed and built in the 1960s primarily for the production of transuranic isotopes. The HFIR is equipped with two concentric cylindrical blade assemblies, known as control cylinders, that are used to control reactor power. These control cylinders, which become highly radioactive from neutron exposure, are periodically replaced as part of the normal operation of the react… more
