United States Nuclear Regulatory Commission - Protecting People and the Environment

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 inform addressees of recently identified “urgent” safety issues, may request information and/or action, and require written responses under oath or affirmation.

Document Number Description
80-10 Contamination of Nonradioactive System and Resulting Potential for Unmonitored, Uncontrolled Release of Radioactivity to Environment
79-09 Spill of Radioactively Contaminated Resin
79-07 Rupture of Radwaste Tanks

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 the NRC to assess the significance of the matter.

Document Number Description
81-09 Containment Effluent Water that Bypasses Radioactivity Monitor
79-21 Prevention of Unplanned Releases of Radioactivity
77-14 Separation of Contaminated Water Systems from Noncontaminated Plant Systems
77-10 Vacuum Conditions Resulting in Damage to Liquid Process Tanks

Generic Letters

Generic letters address generic safety, safeguards, or the environmental issues by requesting that addressees perform analyses, propose corrective actions, submit technical information that the NRC needs to perform its mission, or submit proposed changes to technical specifications or license commitments. Generic letters may also state new staff technical or policy positions or solicit voluntary participation in technical pilot programs.

Document Number Description
81-039 NRC Volume Reduction Policy
81-038 Storage of Low-Level Radioactive Wastes at Power Reactor Sites
80-009 Low-Level Radioactive Waste Disposal

Information Notices

Information notices inform addressees of significant, recently identified operating experience that involves safety, safeguards, or environmental issues. Addressees are expected to review the information for applicability to their operations, and consider appropriate actions to avoid similar problems. However, information notices do not impose or imply new requirements, do not interpret regulations, and do not require specific actions.

Document Number Description

90-31 Update on Waste Form and High Integrity Container Topical Report Review Status, Identification of Problems with Cement Solidification and Reporting of Waste Mishaps
87-07 Quality Control of Onsite Dewatering/Solidification Operations by Outside Contractors
86-43 Problems with Silver Zeolite Sampling of Airborne Radioiodine
86-20 Low-Level Radioactive Waste Scaling Factors, 10 CFR Part 61
