Content:
facilities that could involve the use of hazardous materials (e.g., oil or toxic chemicals) or pose other risks (e.g., a barge collision with an intake structure or an airplane crash at the site). On the basis of the information provided in SRP Sections 2.2.1-2.2.2, potential accidents regarded as design-basis events are determined and reviewed under SRP Section 2.2.3. Design-basis events on site or in the vicinity of the nuclear plant are defined as accidents with a probability of occurrence on an order of magnitude of 10-7 per year, with potential consequences sufficiently serious to affect the safety of the plant to the extent that 10 CFR Part 100 guidelines could be exceeded. If unfavorable physical characteristics exist, the proposed site may be found acceptable if the facility design includes appropriate and adequate engineering safeguards to compensate for the observed deficiencies. Regulatory Guide 1.91 provides guidance for evaluating postulated explosions on transportation routes near nuclear plants. Meeting these requirements provides assurance that the plant has adequate protection and can operate with an acceptable degree of safety in the event of an accident caused by the presence of hazardous materials or activities on site and/or at nearby industrial, military, or transportation facilities. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case.
