The U.S. Energy Dept. is storing at least 820 million kg of nuclear & non-nuclear materials in inventory at 44 sites in 19 states: spent nuclear fuel, plutonium, natural & enriched uranium, depleted uranium, lithium, sodium, lead, chemicals, weapons components, scrap metal & material. Three materials make up an estimated 95% of the total: depleted uranium, scrap metal, & lithium. Left unattended, much of this material could present environmental, health, or safety risks. Maintaining these materials in a safe condition costs millions of dollars/year.

Only then will future generations recognize this exciting but uncertain time as the beginning of the closing of the circle on the splitting of the atom. GLOSSARY Alpha particle. A particle consisting of two protons and two neutrons. given off by the decay of many elements. including uranium. plutonium. and radon. Alpha particles cannot penetrate a sheet of paper. However. alpha emitting isotopes in...
Стр. 188 - high-level radioactive waste" means — (A) the highly radioactive material resulting from the reprocessing of spent nuclear fuel, including liquid waste produced directly in reprocessing and any solid material derived from such liquid waste that contains fission products in sufficient concentrations; and (B) other highly radioactive material that the Commission, consistent with existing law, determines by rule requires permanent isolation.
Стр. 188 - Heavy Metals Metallic elements with high atomic weights, eg, mercury, chromium, cadmium, arsenic, and lead. They can damage living things at low concentrations and tend to accumulate in the food chain.
Стр. 88 - Final Environmental Impact Statement for a Geologic Repository for the Disposal of Spent Nuclear Fuel and High-Level Radioactive Waste at Yucca Mountain, Nye County, Nevada.
Стр. 188 - Office" means the Office of Civilian Radioactive Waste Management established in section 305. 2 (18) The term "repository" means any system licensed by the Commission that is intended to be used for, or may be used for, the permanent deep geologic disposal of high-level radioactive waste and spent nuclear fuel, whether or not such system is designed to permit the recovery, for a limited period during initial operation, of any materials placed in such system. Such term includes both surface and subsurface...
Стр. 189 - Isotopes. Different forms of the same chemical element that differ only by the number of neutrons in their nucleus. Most elements have more than one naturally occurring isotope. Many more isotopes have been produced in reactors and scientific laboratories. K Reactor.

Стр. 188 - Fusion; The process whereby the nuclei of light elements, especially those of the isotopes of hydrogen (deuterium and tritium), combine to form the nucleus of a heavier element, with the release of substantial amounts of energy.
Стр. 187 - A beta particle is identical with an electron. It has a short range in air and a low ability to penetrate other materials.
Стр. 189 - mixed waste" means waste that contains both hazardous waste and source, special nuclear, or by-product material subject to the Atomic Energy Act of 1954 (42 USC 2011 et seq.).
