Company, Train 154, Derailment with Fire and Explosion, Laurel, Mississippi, January 25, 1969,” October 6, 1969 (reference 5) establishes as 350 meters (383 yards), with the range for smaller pieces extending to 500 meters (547 yards). Project 485, Aircraft Considerations, Pre-application Site Review, Boardman Nuclear Plant, October 1973 (reference 10) may also be used to evaluate the risk posed by nearby military aviation. 2. The staff will review the site and its vicinity for the presence of industrial activities, such as fixed manufacturing, processing, and storage facilities. The review should include all identified facilities and activities within 8 kilometers (5 miles) of the plant. The reviewer should be especially alert to any potentially hazardous activities in close proximity to the plant because an extensive variety of activities can have damage potential at ranges under about 1 kilometer (0.62 miles). Facilities and activities at distances greater than 8 kilometers (5 miles) should be considered if they have the potential for affecting plant safety-related features. 3. The staff will review the specific information relating to types of potentially hazardous material used, stored, or transported in the vicinity of the site—including distance, quantity, and frequency of shipment—to eliminate as many of the potential accident situations as possible by inspection, based on past review experience. References 1 and 2 identify safe separation distances for explosives, and References 3 and 4 include similar information for toxic chemicals. The staff may use Reference 7 as an example of an acceptable risk assessment for pipeline hazards, Reference 9 for cryogenic fuels, and Reference 8 for tank barge risks. The staff should determine whether bulk storage is present on site. For example, hydrogen and oxygen may be used in boiling-water reactors for controlling oxygen concentration in the reactor coolant, properly operating the off-gas system, and suppressing
