Technical Peer Review Report: Radionuclides in the Environment
: In stock
The scope of this plan of the Office of Nuclear Regulatory Research is the overall research of radionuclide transport in the environment (RTE) from the place and time of release to the place and time of exposure of a member of the public. The RTE research program provides data and models for use in assessing the effect on public health and safety and the environment from nuclear materials that enter the environment from U.S. Nuclear Regulatory Commission (USNRC) licensed activities. The technical issues examined include: (1) source-term characterization; (2) the effectiveness of engineered and natural containment systems surrounding the radioactive material; (3) multi-phase flow of water, including episodic infiltration, into and through contaminated systems; (4) the transport of radioactive material through the geosphere; (5) the transport of radioactive material through the biosphere; and (6) exposures of members of the public to radiation from these materials. Excluded from consideration are biological effects of ionizing radiation and the associated modeling and assumptions. Results from the RTE research program are intended to be generically applicable to USNRC licensing activities including the decommissioning of facilities; disposal of uranium mill tailings; low-level radioactive waste disposal; and high-level radioactive waste disposal. The RTE research program includes the conduct of independent confirmatory and anticipatory research and analyses to provide data and models and other technical information that will support: (1) credible, realistic, and defensible estimates of risk to the public from alternative courses of action at decommissioning and nuclear waste disposal facilities; and (2) agency decisions regarding decommissioning and waste disposal.
