This is the concept for Project Payette, a nuclear event in the Seismic Detection Research Program. For this experiment, a nuclear explosive in the range of 5 to 10 kt will be detonated at a depth of 2000 to 3000 ft in an underground cavity of sufficient size that the walls of the cavity experience only elastic motion. The site will be located in a salt dome. Project Payette has been divided into three phases. Phase I will include site evaluation and engineering design of the construction of the cavity. It is estimated to require about 1 year. Phase II will include construction of the cavity and emplacement hole. It is estimated to require about 2 years. Phase III will include emplacement of instruments and the device, the detonation and the post-shot program including cavity re-entry. This is estimated to require about 1 year. The scope of this concept is intended to define Project Payette sufficiently will that Phase I work may proceed.
