​​​​​​The U.S. Nuclear Regulatory Commission (NRC) publishes notices to provide information regarding safety, safeguards and environmental issues. The notices bring significant, recently-identified safety, security, or environmental information to the attention of licensees. NRC expects licensees to review the information for applicability to their facilities and consider appropriate actions to avoid similar problems.

Regulatory issue summaries (a new product) are used to (1) document NRC endorsement of the resolution of issues addressed by industry-sponsored initiatives, (2) solicit voluntary licensee participation in staff-sponsored pilot programs, (3) inform licensee of opportunities for regulatory relief, (4) announce staff technical or policy positions not previously communicated to industry or not broadly understood, and (5) address matters previously reserved for administrative letters.

These Notices and Summaries can be accessed at the NRC Generic Communications site.
