Terms Used In CFR > Title 10 > Chapter I > Part 63 > Subpart A - General Provisions

  • Barrier: means any material, structure, or feature that, for a period to be determined by NRC, prevents or substantially reduces the rate of movement of water or radionuclides from the Yucca Mountain repository to the accessible environment, or prevents the release or substantially reduces the release rate of radionuclides from the waste. See 10 CFR 63.2
  • Commission: means the Nuclear Regulatory Commission or its duly authorized representatives. See 10 CFR 63.2
  • Complaint: A written statement by the plaintiff stating the wrongs allegedly committed by the defendant.
  • Contract: A legal written agreement that becomes binding when signed.
  • Damages: Money paid by defendants to successful plaintiffs in civil cases to compensate the plaintiffs for their injuries.
  • Design bases: means that information that identifies the specific functions to be performed by a structure, system, or component of a facility and the specific values or ranges of values chosen for controlling parameters as reference bounds for design. See 10 CFR 63.2
  • Director: means the Director of the Nuclear Regulatory Commission's Office of Nuclear Material Safety and Safeguards. See 10 CFR 63.2
  • Disposal: means the emplacement of radioactive waste in a geologic repository with the intent of leaving it there permanently. See 10 CFR 63.2
  • DOE: means the U. See 10 CFR 63.2
  • Engineered barrier system: means the waste packages, including engineered components and systems other than the waste package (e. See 10 CFR 63.2
  • Event sequence: means a series of actions and/or occurrences within the natural and engineered components of a geologic repository operations area that could potentially lead to exposure of individuals to radiation. See 10 CFR 63.2
  • Geologic repository: means a system that is intended to be used for, or may be used for, the disposal of radioactive wastes in excavated geologic media. See 10 CFR 63.2
  • Geologic repository operations area: means a high-level radioactive waste facility that is part of a geologic repository, including both surface and subsurface areas, where waste handling activities are conducted. See 10 CFR 63.2
  • Geologic setting: means the geologic, hydrologic, and geochemical systems of the region in which a geologic repository is or may be located. See 10 CFR 63.2
  • Isolation: means inhibiting the transport of radioactive material to:

    (1) The location of the reasonably maximally exposed individual so that radiological exposures will not exceed the requirements of §63. See 10 CFR 63.2

  • Permanent closure: means final backfilling of the underground facility, if appropriate, and the sealing of shafts, ramps, and boreholes. See 10 CFR 63.2
  • Reasonably maximally exposed individual: means the hypothetical person meeting the criteria specified at §63. See 10 CFR 63.2
  • Reference biosphere: means the description of the environment inhabited by the reasonably maximally exposed individual. See 10 CFR 63.2
  • Restricted area: means an area, access to which is limited by the licensee for the purpose of protecting individuals against undue risks from exposure to radiation and radioactive materials. See 10 CFR 63.2
  • Saturated zone: means that part of the earth's crust beneath the regional water table in which statistically all voids, large and small, are filled with water under pressure greater than atmospheric. See 10 CFR 63.2
  • Site: means that area surrounding the geologic repository operations area for which DOE exercises authority over its use in accordance with the provisions of this part. See 10 CFR 63.2
  • Site characterization: means the program of exploration and research, both in the laboratory and in the field, undertaken to establish the geologic conditions and the ranges of those parameters of the Yucca Mountain site, and the surrounding region to the extent necessary, relevant to the procedures under this part. See 10 CFR 63.2
  • Statute: A law passed by a legislature.
  • Underground facility: means the underground structure, backfill materials, if any, and openings that penetrate the underground structure (e. See 10 CFR 63.2
  • Unsaturated zone: means the zone between the land surface and the regional water table. See 10 CFR 63.2
  • waste: means HLW and radioactive materials other than HLW that are received for emplacement in a geologic repository. See 10 CFR 63.2
  • Waste form: means the radioactive waste materials and any encapsulating or stabilizing matrix. See 10 CFR 63.2
  • Waste package: means the waste form and any containers, shielding, packing, and other absorbent materials immediately surrounding an individual waste container. See 10 CFR 63.2
  • Water table: means that surface in a groundwater body, separating the unsaturated zone from the saturated zone, at which the water pressure is atmospheric. See 10 CFR 63.2
