Under the U.S. Nuclear Regulatory Commission`s (NRC) siting criteria for a high-level waste (HLW) repository (10 CFR Part 60.122), one of the favorable conditions refers to a climatic regime where average annual historic precipitation is a small percentage of the average annual potential evapotranspiration (PET). A license application for the Yucca Mountain site will need to demonstrate whether or not this favorable condition is present. This paper describes the technical basis for a newly developed review plan on this topic. The review plan will be published in NRC`s License Application Review Plan, and will therefore be available for public review and comment. We present this information recognizing that the Congress is currently considering changes in how a HLW repository will be licensed.
