123 GO Act

This bill aims to help U.S. companies sell nuclear technology and services overseas. It tells the State Department to lead talks with other countries and strike at least 20 new “123 agreements” (the deals that allow nuclear cooperation) by January 3, 2029, and to renew or update ones that are set to expire within 10 years after the law takes effect. It also backs a recent executive order that supports deploying advanced nuclear reactors for national security needs.

The bill creates a program to make U.S. nuclear suppliers, investors, and lenders more competitive abroad. This includes speeding up government-to-government agreements on nuclear energy and fuel supply chains, pushing more countries to follow a global nuclear liability treaty, finding and easing export red tape, and encouraging partner countries to choose U.S. nuclear technology and fuel.

• Who is affected: U.S. nuclear suppliers, investors, and lenders; the State Department; countries considering U.S. nuclear deals
• What changes: At least 20 new cooperation agreements by 2029; renewals of expiring deals; steps to speed approvals, cut export hurdles, and promote global safety/liability standards
• When: New agreements targeted by January 3, 2029; renewals for agreements expiring within 10 years after enactment
