Research Information Letters

Research Information Letters (RILs) are documents issued by the NRC's Office of Nuclear Regulatory Research to the NRC regulatory and regional offices that summarize, synthesize, and/or interpret significant research information relevant to a given technical area, provide new or revised information, and discuss how that information may be used in regulatory activities. RILs can improve regulatory efficiency and effectiveness by providing important, pertinent information in a timely, concise, and comprehensive summary.
