This book recounts the issues raised and the viewpoints aired at a recent symposium on repository licensing. It summarizes the problems surrounding the setting of an Environmental Protection Agency standard for the release of radionuclides and the regulatory problems inherent in meeting such a standard. Symposium participants came from a variety of federal agencies and advisory groups, state governments, public interest groups, engineering firms, national laboratories, and foreign and international organizations. The book illustrates the strong feeling in the radioactive waste disposal community that changes must be made if the United States is to fulfill its promise of safe management of current and future nuclear waste.
