Summary

Story summary

The U.S. Nuclear Regulatory Commission approved a permit for TVA’s 300-MW modular reactor at Clinch River.
The reactor uses a GE Vernova Hitachi boiling-water design that generates steam directly in the vessel.
The approval follows a 14-month NRC review and is the agency’s second major reactor approval this year.
TVA must still obtain an operating license before loading fuel, and says the project will meet growing regional power demand.

History

Historical Context

On March 28 1979 the Three Mile Island Unit 2 melt released radioactive gases, prompting the NRC to impose stricter safety rules after a cleanup that cost about $1 billion. The accident also halted U.S. reactor growth, with 52 plants canceled between 1980 and 1984. Decades later, the NRC’s 14-month review cleared TVA’s 300-MW Clinch River SMR, showing how those reforms now enable new modular reactors.
