UNITED STATES NUCLEAR REGULATORY COMMISSION OFFICE OF NUCLEAR MATERIAL SAFETY AND SAFEGUARDS WASHINGTON, D.C. 20555 February 1, 1993 NRC INFORMATION NOTICE 93-07: CLASSIFICATION OF TRANSPORTATION EMERGENCIES Addressees All Licensees required to have an emergency plan. Purpose The U.S. Nuclear Regulatory Commission is issuing this information notice to alert licensees of a recent incident where the classification of a transportation accident was confusing and misleading. It is expected that licensees will review this information for applicability to their licensed activities and consider actions, as appropriate, to avoid similar problems. However, suggestions contained in this notice do not constitute any new NRC requirements, and no written response is required. Description of Circumstances On December 16, 1991, a truck carrying unirradiated (fresh) nuclear fuel was involved in an accident in Massachusetts. The fuel was being shipped from a fuel fabrication plant in North Carolina, to a reactor in Vermont. The fuel shipment consisted of 24 fresh fuel assemblies, packaged 2 each, in 12 shipping containers. As a result of the accident, the truck and shipping containers carrying the fresh fuel were engulfed in a fire that lasted for almost 3 hours. The shipper declared a "Site Emergency" and responded in accordance with its emergency plan. Despite the collision and subsequent fire, there were no deaths nor serious injuries. However, the accident did result in substantial property loss, which included the truck, shipping containers, and damaged fuel assemblies. After the incident, NRC staff reviewed the emergency response measures taken. The results were reported in NUREG-1458, "Emergency Response to a Highway Accident in Springfield, Massachusetts, on December 16, 1991." This report concluded that the shipper's classification "is confusing since it does not have the same meaning as a site emergency for a fixed facility. Consideration should be given to developing a standard classification for transportation events that has its own terminology." Discussion The emergency classifications defined in 10 CFR Parts 30, 40, 50, and 70 are intended for emergencies at a fixed site (i.e., the licensee's facility). When a Notification Of Unusual Event (NOUE), Alert, or Site Area Emergency is declared, the licensee is required to immediately notify offsite response 9301260032. IN 93-07 February 1, 1993 Page 2 of 2 agencies responsible for taking actions to protect the public within a few miles of the licensee's facility. Declaring an NOUE, Alert, or Site Area Emergency for a transportation accident tens or hundreds of miles away from a licensee's facility causes unnecessary confusion among offsite response agencies. After considering the need to develop a standard classification for transportation events, the staff concluded that a rulemaking to establish an additional emergency classification was not warranted. Most transportation accidents are reported by licensees that are not required by regulation to have an emergency plan. The cause of the confusion in the Springfield accident was the classification of an offsite emergency using the scheme established in the regulations for an onsite emergency. Only licensees required to have an emergency plan would tend to use this classification scheme. Therefore the staff believes that making licensees with emergency plans aware of the potential for confusion and having NRC licensing staff determine how transportation accidents are classified in future reviews of emergency plans is sufficient to address this problem. Licensees required to maintain an emergency plan may want to review their emergency classification procedures and consider the need to establish a separate classification (e.g., transportation emergency) for offsite transportation accidents that require activation of the licensee's emergency organization.
