Draft Regulatory Guide: Acceptability of ASME Code, Section III, Division 5, ‘‘High Temperature Reactors’’

EnergyTechnology

Summary

The Nuclear Regulatory Commission is proposing to accept safety standards from ASME (a major engineering organization) for a new type of nuclear reactor called high temperature reactors. This would make it easier for companies to build and operate these advanced reactors by using established engineering rules instead of creating new ones from scratch.

Key Points

  • 1The NRC is considering whether to officially recognize ASME Code Section III, Division 5 standards as acceptable for high temperature reactor designs
  • 2High temperature reactors are a newer nuclear technology that operates at higher temperatures than traditional reactors, potentially offering improved safety and efficiency
  • 3If approved, this regulation would streamline the approval process for companies developing high temperature reactors by allowing them to follow existing ASME engineering standards
  • 4The public can submit comments on this proposed rule until February 27, 2025
  • 5This change primarily affects nuclear reactor manufacturers and utility companies planning to build or operate advanced reactor facilities
