This analysis is prepared by the Mined Geologic Disposal System (MGDS) Waste Package Development (WPD) department with the objective of providing a comprehensive, conservative estimate of the consequences of the criticality which could possibly occur as the result of commercial spent nuclear fuel emplaced in the underground repository at Yucca Mountain. The consequences of criticality are measured principally in terms of the resulting changes in radionuclide inventory as a function of the power level and duration of the criticality. The purpose of this analysis is to extend the prior estimates of increased radionuclide inventory (Refs. 5.52 and 5.54), for both internal and external criticality. This analysis, and similar estimates and refinements to be completed before the end of fiscal year 1997, will be provided as input to Total System Performance Assessment-Viability Assessment (TSPA-VA) to demonstrate compliance with the repository performance objectives.

The Hanford Nuclear Reservation Tank Farms` underground waste tanks have been used to store liquid radioactive waste from defense materials production since the 1940`s. Waste in certain of the tanks may contain material in the form of ferrocyanide or various organic compounds which could potentially be susceptible to condensed phase chemical reactions. Because of the presence of oxidizing materials (nitrate compounds) and heat sources (radioactive decay and chemical reactions), the ferrocyanide or organic material could potentially fuel a propagating exothermic reaction with undesirable consequences. Analysis and experiments indicate that the reaction propagation and/or initiation may be prevented by the presence of sufficient moisture in the waste. Because the reaction would probably be initiated at the surface of the waste, evidence of sufficient moisture concentration would help provide evidence that the tank waste can continue to be safely stored. The Surface Moisture Measurement System (SMMS) was developed to collect data on the surface moisture in the waste by inserting two types of probes (singly) into a waste tank-a neutron probe and an electromagnetic inductance (EMI) probe. The sensor probes will be placed on the surface of the waste utilizing a moveable deployment arm to lower them through an available riser. The …

This document summarizes the information on the historical uses, present status, and the sampling and analysis results of waste stored in Tank 241-BX-103. This report supports the requirements of Tri- Party Agreement Milestone M-44-09.

This report presents results of a suite of uniaxial compressive tests conducted to provide laboratory data to determine how radiation affects the compressive strength of Topopah Spring Tuff, which is the rock type for the proposed geologic repository at Yucca Mountain, in Nevada. The repository would be designed for storing spent fuel and other high-level radioactive wastes. We need to better understand what effect radiation has on the compressive strength of this type of rock because emplacement of radioactive waste may impose a radiation field on the rock that is exposed in the emplacement drifts and other excavations associated with the proposed repository. Thus, we must determine whether exposure to radiation will alter the mechanical strength or other geomechanical properties of the rock in the very near-field region of the repository. Until now, data describing the effect of radiation on tuff from the potential repository horizon have not been available. The approach taken was to precisely measure rock behavior in uniaxial compression on irradiated and non-irradiated samples of Topopah Spring Tuff. Identical procedures were used for preparing and testing the samples tested for radiation effects and those that were not irradiated, except for the exposure to gamma radiation. Results for …

Interest in restructuring (including eliminating) the Department of Energy (DOE) and its laboratories has increased since the end of the Cold War, and especially since the beginning of the 104th Congress. A number of non-legislative proposals and activities to this end are reviewed, including DOE's own proposals for "alignment and downsizing" of the Department and its laboratories.

Historically, coastal states managed marine sport and commercial fisheries in nearshore waters, where most marine seafood was caught. However, as fishing techniques improved and offshore resources were discovered, more fishers ventured farther offshore.

Amending Federal laws to protect wetlands, especially agricultural wetlands, is a contentious issue for the 104th Congress. Critics contend that current programs are excessive in their reach and unfairly restrict private landowners. Supporters counter that these programs are critical if the Nation is to achieve the stated goal of no-net-loss of wetlands. The two major statutes under which agricultural wetlands are protected are swampbuster, enacted in the Agriculture, Food, Trade, and Conservation Act of 1985, and section 404, enacted in the 1972 Clean Water Act. This report describes both programs, emphasizing how they relate to each other. It explains how each program works, especially on agricultural wetlands, and the likely effect of proposed revisions to swampbuster. Also, it briefly considers other legislative proposals that would amend the section 404 program, which, if enacted, would further affect how agricultural wetlands are protected.

On May 31, the President formally recommended a one-year extension of most-favored-nation (MFN) treatment for China. [l] MFN treatment allows China's products to enter the United States at the same low tariff rates that apply to virtually all trading partners. Supporters of MFN status for China argue, among other things, that denial of MFN status could bring retaliatory actions that would hurt U.S. agricultural exports. China has threatened to retaliate if the United States denies it MFN treatment. Since China is a leading market for U.S. agricultural products, the threat of such action is a serious matter for U.S. agricultural interests.

Final congressional approval was given to H.R. 2854, the Federal Agricultural Improvement and Reform (FAIR) Act, otherwise known as the "1996 farm bill," on March 28, 1996. President Clinton signed the bill into law on April 4, 1996 (P.L. 104-127). In tabular format, this CRS report lays out in descriptive, rather than legislative language, the major provisions of the new farm bill in contrast to preceding law.

On August 3, 1996, President Clinton signed P.L. 104-170, which contains significant amendments to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and Federal Food, Drug, and Cosmetic Act (FFDCA). Although it does not repeal the Delaney Clause, the new law removes pesticide residues from its purview. It requires EPA to set "safe" tolerances for residues of pesticides on both raw and processed food to provide "a reasonable certainty of no harm" from exposure to the pesticide residue, other dietary residues, and non-food sources. It also will expedite pesticide registration under FIFRA for minor uses; improve data collection on the effect of pesticides in children's diets; and prohibit states from regulating food based on pesticide residue concentrations below recently established federal tolerances.

The President signed P.L. 104-205, the Department of Transportation and Related Agencies Appropriations Act, 1997, (FY1997 Act) on September 30, 1996. This action completes work on Department of Transportation (DOT) and related agencies appropriations for the year.

This report discusses the effect of human activities on global climate change. Human activities, particularly burning of fossil fuels, have increased atmospheric carbon dioxide (CO2) and other trace gases, including chlorofluorocarbons (CFCs), methane, and nitrous oxide.

For two decades, scientists have been warning that chlorofluorocarbons (CFCs) and Halons (bromine-containing fluorocarbons) may deplete the stratospheric ozone shield that screens out some of the sun's harmful ultraviolet rays and thus regulates the amounts which reach the Earth's surface. CFCs have been used as refrigerants, solvents, foam blowing agents, and outside the United States as aerosol propellants; Halons are used primarily as firefighting agents. Increased radiation could result in an increase in skin cancers, suppression of the human immune system, and decreased productivity of terrestrial and aquatic organisms, including some commercially important crops.

This engineering report documents the entry and characterization of the Rupture Loop Annex Ion Exchange (RLAIX) Vault located near the 309 Building`s Plutonium Recycle Test Reactor (PRTR). Twelve ion exchange columns were found in the vault. Some of which contained transuranics, Cs 137, and Co 60. The characterization information is necessary for future vault cleanout and column disposal.
