ill be performed. For pipeline hazards, Reference 7 may be used as an example of an acceptable risk assessment. For cryogenic fuels, Reference 9 may be used, and for tank barge risks, Reference 8. For military aviation, Reference 10 may be used. Safe separation distances for explosives are identified in References 1 and 2, and for toxic chemicals, References 3 and 4 should be consulted. The distance from nearby railroad lines is checked to determine if the plant is within the range of a "rocketing" tank car which, from Reference 5, is taken to be 350 meters with the range for smaller pieces extending to 500 meters. The reviewer should determine whether bulk storage of liquid or compressed hydrogen and liquid oxygen is present on site. Hydrogen and oxygen may be used in BWRs for the control of oxygen concentration in the reactor coolant, for proper operation of the offgas system, and to suppress corrosion and corrosion product release in the condensate and feedwater system. Reference 13 may be used for guidance to assess hazards associated with the storage and use of these materials. The reviewer should determine whether bulk storage of propane exists on site. Propane may be used for incineration of low-level radioactive waste (dry combustible waste or contaminated oil). Reference 14 contains appropriate review guidance to assess the risk associated with the storage and use of propane.24 4. Potential accidents which cannot be eliminated from consideration as design basis events because the consequences of the accidents, if they should occur, could be serious enough 2.2.1-5 DRAFT Rev. 3 - April 1996 to affect plant safety-related features, are identified. Potential accidents so identified are assessed in detail, using criteria in Standard Review Plan SRP Sections 2.2.3, 3.5.1.5, or 3.5.1.6, as appropriate. For design certification reviews, the above review procedures are used to verify that the design as set forth in the standard SAR (including inspections, tests,
