Nuclear Regulatory Commission Seeks Public Feedback on Cable and Field Splice Safety at Nuclear Power Plants

The Nuclear Regulatory Commission (NRC) is initiating a public comment period for a proposed revision to its guidance on cable and field splice safety at nuclear power plants. The draft guide, DG-1442, aims to update the standards for electrical systems critical to facility operation by aligning with the 2023 IEEE standard (383-2023). This revision is necessary to incorporate improved guidelines for the production and utilization of facilities, ensuring the reliability and safety of electrical systems.

Key Takeaways:

• The NRC is seeking public feedback on a proposed revision to its guidance for cable and field splice safety at nuclear power plants, which aims to update the standards for electrical systems critical to facility operation.
• The draft guide, DG-1442, proposes an acceptable way for plants to meet regulatory requirements for environmental qualification of these vital components, aligning with the 2023 IEEE standard (383-2023).
• The previous NRC guide was based on an older 2003 version of the IEEE standard, and this change is meant to incorporate improved guidelines into the regulatory framework for production and utilization facilities.
• The public comment period is open for 32 days, concluding on September 8, 2025, and comments can be submitted through the Federal rulemaking website by searching for Docket ID NRC-2025-0080.
• Technical questions about the guide can be directed to Edmund Kleeh or Vance Petrella at the NRC.
• The full document is available online through the agency's website.

Statistics:

• The comment period is open for 32 days, concluding on September 8, 2025.
• The NRC guide is updating from the 2003 IEEE standard to the 2023 IEEE standard (383-2023).
• The proposed revision aims to align with the 2023 IEEE standard, which provides greater instruction for qualifying cables and splices.
