Topics of Discussion
- Feedback on Framework of Regulatory Guides for electrical standards
- Are there any inconsistencies?
- Are there any improvements that can be made?
- Feedback on Industrys use of Regulatory Guides
- Are the Periodic Reviews useful in communicating status? How can they be improved?

Status of Significant Regulatory Guides
- RG 1.89 (60780-323) - expected to have draft out for public comment by the end of the 4th quarter of FY2020.
- Status of RG to endorse IEEE Std. 741 - expected to have draft out for public comment before end of Jan. 2021.
- RG to endorse IEEE Std. 1819 - this project has started, and a schedule is being developed.
- RG 1.9 (IEEE Stds. 387 & 2420) - expected to have draft out for public comment before end of calendar year 2020.

Vision & Strategy of IEEE Electrical Standards - ROADMAP Focus on the agency mission and regulatory requirements when determining a RG is needed or requires updating.
Represents a technically viable approach for allowing licensees, manufacturers, vendors, and NRC staff to effectively navigate and use regulatory guidance.
Prevents the ad hoc approach of generating additional regulatory guidance documents.
Combine related standards on a technical topic into one RG.
Reduced staff hours as compared to updating and maintaining several RGs Reduced costs as compared to updating and maintaining several RGs Technical Efficacy - Generates efficiencies such that industry/users have a one-stop shop on NRC positions on a particular topic Process Efficiency - review process is streamlined for one RG on a technical topic (i.e. one public comment period on a technical topic)
Updates to a combined RG endorsing several standards would only be considered when there are significant changes that impact the staffs position or provide additional clarifications Examples:
RG. 1.100 (seismic qualification) includes both 344-60980 & C37.98 One RG on the design of DC systems to include 946 (design), 1189 (selection of batteries),
1375 (protection), & 2405 (battery chargers), all of which are critical to a DC system design.
For standards in the early stages of development, NRC action will be determined once early drafts are available to ascertain how the standard fulfills the agencys mission and provides methods to meet regulatory requirements.

Feedback on NRC Communication
- Are the Periodic Reviews useful in communicating status? How can they be improved?
- What communications to the industry and public would be useful for status on RG development?
- NRC encourages the letters from IEEE on priority U.S.NRC United States Nuclear Regulatory Commission Protecting People and the Environment
