FR 2021-02720

The document issued by the U.S. Nuclear Regulatory Commission (NRC) is a draft regulatory guide identified as DG-1304. This guide is aimed at providing guidance on safety-related steel structures and steel-plate composite walls used in nuclear facilities, which are not part of reactor vessels or containments. It aligns with the 2018 version of the ANSI/AISC N690 standard but includes unique exceptions and clarifications for these structures. The NRC invites the public to submit feedback on this draft by March 29, 2021. Comments can be submitted electronically through the Federal Rulemaking website or by mail.

Summary of the Document

The NRC's draft guide is part of their ongoing efforts to set guidelines for safety in nuclear facilities. DG-1304 specifically addresses safety-related steel structures outside of the core reactor components. While it predominantly follows the ANSI/AISC N690 standard, it introduces specific changes that require review and feedback from industry stakeholders and the public. Feedback is considered crucial, as it helps the NRC refine the guidelines to ensure they adequately address safety needs without imposing unnecessary burdens.

Significant Issues and Concerns

There are several points worth discussing in this document:

• Cost Implications: The document does not clearly outline the potential costs or economic impact of implementing the guidance. This is crucial information, as stakeholders need to be aware of any financial commitments or adjustments they may need to make.

• Technical Language: Terms such as "backfitting" and "forward fitting" are used without adequate explanation. This technical jargon might hinder the understanding of individuals who are not familiar with regulatory compliance, thus limiting broader public engagement.

• Clarifications and Exceptions: The document references exceptions and clarifications to the standard but does not provide a simple explanation of how these might influence different stakeholders involved, which could lead to uncertainty or misinterpretation of their responsibilities.

• Reference Documents: The document references standards and technical documents, such as ANSI/AISC N690-2018, without elaborating on what these entail, which could be confusing for readers who are not industry experts.

Broad Public Impact

The draft guide, if finalized, will influence safety protocols for steel structures in nuclear facilities. By ensuring that these structures meet high safety standards, the NRC aims to protect public health and safety in areas surrounding these facilities. However, the technical nature of the document may create barriers for public understanding, potentially reducing the effectiveness of the feedback process.

Impact on Specific Stakeholders

The document will primarily impact stakeholders within the nuclear industry, including regulatory compliance officers, engineers, and facility operators. The lack of clarity on exceptions and cost implications may lead to confusion and necessitate further inquiries, which could delay compliance efforts. On the positive side, the guide aims to increase safety, which can enhance the industry's overall reputation and reliability.

Conclusion

Overall, the draft regulatory guide DG-1304 is an important document that seeks to enhance safety standards for steel structures in nuclear facilities. However, the NRC needs to address several concerns, particularly in providing clearer information on costs, exceptions, and technical terminology, to ensure all stakeholders can efficiently provide feedback and prepare for potential implementations. This enhanced clarity could lead to more effective compliance and, ultimately, greater safety in the nuclear sector.
