About the topic: Standards and regulations for the management, transportation and disposal of radioactive materials have been key to the development of strategies for the handling and disposing of radioactive materials at the “back-end” of the nuclear fuel cycle.  This presentation summarizes previous U.S. experience in developing a standard and regulations for the geologic disposal of spent nuclear fuel and high-level radioactive waste.  The main purpose of a standard and its implementing regulations should be to protect human health and the environment, but the structure of the standard and regulations, as well as the standard-of-proof for compliance, should not extend beyond what is scientifically possible and reasonable.  The demonstration of compliance must not only be compelling, but it must also be able to sustain scientific and public scrutiny.  We can benefit from the sobering reality of how difficult it is to project the future behavior of a geologic repository over extended spatial and temporal scales that stretch over tens of kilometers and out to a million years.
