This bill aims to reauthorize the West Valley Demonstration Project by amending its existing statutory provisions. The primary purpose is to update the project's funding authorization, ensuring its continued operation and environmental remediation efforts. Specifically, the legislation revises Section 3(a) of the West Valley Demonstration Project Act to significantly increase and extend its financial allocation. It replaces the previous authorization of $75,000,000 for each of fiscal years 2020 through 2026 with an authorization of $150,000,000 for each of fiscal years 2027 through 2037 . This amendment effectively doubles the annual funding and extends the project's reauthorization by 11 years.
