1. (a) DOE must demonstrate, using performance assessment, that there is a reasonable expectation that the reasonably maximally exposed individual receives no more than the following annual dose from releases from the undisturbed Yucca Mountain disposal system:

   1. (1) 0.15 mSv (15 mrem) for 10,000 years following disposal; and
   2. (2) 1.0 mSv (100 mrem) after 10,000 years, but within the period of geologic stability.
2. (b) DOE's performance assessment must include all potential pathways of radionuclide transport and exposure.
