## II. Discussion

The NRC is issuing draft NUREG/CR-7209, “A Compendium of Spent Fuel Transportation Package Response Analyses to Severe Fire Accident Scenarios.” This report summarizes studies of truck and rail transport accidents involving fires, relative to regulatory requirements for shipment of commercial spent nuclear fuel (SNF). The fire accident scenarios were based on the most severe historical railway and roadway fires in terms of their potential impact on SNF containers. The accident scenarios that were analyzed include one railway tunnel fire, two roadway tunnel fires, and one roadway enclosed overpass fire. The combined summary of this work demonstrates that the current NRC regulations and packaging standards provide a high degree of protection to the public health and safety against release of radioactive material in real-world transportation accidents, were such events to involve SNF containers.

The purpose of this notice is to provide the public with an opportunity to review and provide comments on draft NUREG/CR-7209. Any comments received will be considered in the final version or subsequent revisions of the draft NUREG/CR.

Dated at Rockville, Maryland, this 21 day of January, 2016.

For the Nuclear Regulatory Commission.

Christian Araguas,

Chief, Containment, Structural, and Thermal Branch, Division of Spent Fuel Management, Office of Nuclear Materials Safety and Safeguards.
