Uranium in the U.S.A. is controlled by the U.S. Nuclear Regulatory Commission. New uses are being found for depleted uranium, ie., uranium with the percentage of 23su lowered to about 0.2%.

Nuclear power has achieved an excellent safety record. Exceptions are the accidents at Three Mile Island in 1979 and at Chernobyl in 1986. In the United States, safety can be attributed in part to the strict regulation provided by the Nuclear Regulatory Commission, which reviews proposed reactor designs, processes appHcations forUcenses to constmct and operate plants, and provides surveillance of all safety-related activities of a utiUty. The utiUties seek continued improvement in capabiUty, use procedures extensively, and analy2e any plant incidents for their root causes. Similar programs intended to ensure reactor safety are in place in other countries.

Protection of the environment from uncontroHed radioactive release is also a consideration in the use of radiotracers. The quantity and concentration of radionucHdes that may be discharged into sewer systems is limited by regulations of the Nuclear Regulatory Commission (NRC).

When the NRC, headquartered in Rockville, Maryland, took over the responsibiUties of the AEC in 1974, many of the AEC s research and development functions, particularly many covering new technology development and nuclear weapons production, were assumed by the U.S. Department of Energy. However, the NRC has maintained some research and developmental capabiUties which are handled by the NRC s Office of Nuclear Regulatory Research.

Sulfur polymer cement shows promise as an encapsulation and stabilization agent for use with low level radioactive and mixed wastes. Use of SPC allows accommodation of larger percentages of waste than PCC. As of this writing (1997), SPC-treated waste forms have met requirements of both the Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency (EPA). 

Several countries supply monazite concentrates for the world market. Extensive deposits along the coast of western AustraUa are worked for ilmenite and are the primary source of world monazite. Other regions of AustraUa, along with India and Brazil, also supply the mineral. Because monazite contains thorium [7440-29-1], India and Brazil have embargoed its export for many years. In the United States, commerce in the mineral is regulated by the Nuclear Regulatory Commission.

On August 8, 1985, the U.S. Nuclear Regulatory Commission (NRCf requested the operators of nuclear power plants in the U.S. to perform Individual Plant Examinations (IPE) on their plants. IPEs are probabilistic analyses that estimate the core damage frequency (CDF) and containment performance for accidents initiated by internal events (including internal flooding, but excluding internal fire). Generic Letter (GL) 88-20 was issued to implement the IPE request to identify any plant-specific vulnerabilities to severe accidents and report the results to the Commission. ... 

IPEs for 108 plants (Table 11.1-3) were prepared by licensees and/or consultants in varying depth and methodology. They were reviewed by the NRC Office of Nuclear Regulatory Rc.search (NUREG-1560) regarding four major areas ...
