The bill would let nuclear power plants use cheaper, standard commercial-grade steel and concrete in parts of their structures that don't directly affect safety systems, rather than requiring the more expensive specialized materials currently mandated. This change could reduce construction and maintenance costs for nuclear plant operators, though it only applies to non-critical structures that don't control or contain radioactive materials. The Nuclear Regulatory Commission would need to approve which specific structures qualify for this less stringent requirement.
