Generic Communications Regarding Radiation Protection for New Reactors
The U.S. Nuclear Regulatory Commission (NRC) issues generic communications when issues arise that are safety-significant, require technical resolution, and might suggest safety concerns for multiple licensees, manufacturers, suppliers, service groups, or regulatory organizations. For generic communications regarding radiation protection for new reactors, see the following categories on this page:
IE Bulletins
Bulletins (1) request licensee actions and/or information to address significant issues regarding matters of safety, security, safeguards, or environmental significance that have great urgency, and (2) require a written response.

Circulars
Circulars transmit information to licensees or permit holders when (1) the information is of safety, safeguards, or environmental interest, (2) the NRC wishes to disseminate the information within 30 days, and (3) no reply is necessary in order for NRC to assess the significance of the matter.
