The main purpose of this legislation is to end the licensing process for a nuclear waste repository at Yucca Mountain in Nevada. It aims to redirect focus toward exploring alternative uses for the site that could create jobs and provide economic benefits. Key provisions of the legislation include the termination of the existing licensing proceedings for the Yucca Mountain site. This means that the application for constructing a nuclear waste repository will be withdrawn, and the Nuclear Regulatory Commission will stop any related licensing activities.
