Build Nuclear with Local Materials Act of 2026

May 20, 2026

Summary

Tells the Nuclear Regulatory Commission to make a rule that allows regular steel and concrete for parts of nuclear power plants not related to safety.

What problem does this solve?

Building nuclear power plants can be very expensive and slow, partly because of strict rules for all building materials. This bill helps lower costs by allowing the use of standard steel and concrete for buildings not directly related to the plant's safety.

What does this bill do?

Rulemaking for commercial-grade materials

Requires the Nuclear Regulatory Commission (NRC) to start a process within 90 days to create a rule allowing commercial-grade steel and concrete in non-safety structures at nuclear plants.

Safety exception for stricter standards

Allows the NRC to require stricter material standards only if it determines they are necessary to address a specific safety risk and protect public health and security.

Who does this affect?

Nuclear power plant construction companies
The Nuclear Regulatory Commission (NRC)
Steel and concrete suppliers

What is the real world impact?

•

Reduces construction costs for nuclear plants

Lowers the expense and time needed to build new nuclear power plants by permitting the use of standard, widely available steel and concrete for non-critical structures. This could make nuclear energy more affordable.

When does this start?

The bill sets a 90-day deadline for the Nuclear Regulatory Commission to begin its work after the bill becomes law.

Rulemaking initiation

The Nuclear Regulatory Commission must begin the rulemaking process no later than 90 days after this Act becomes law.
