iew identified as part of the primary responsibility of other branches, acceptance criteria and methodologies for these reviews are contained in the referenced SRP section of the corresponding primary review branch.13 II. ACCEPTANCE CRITERIA SABECGB acceptance criteria are based on meeting the relevant requirements of 10 CFR Part 14 100, § 100.10, (Ref. 1) as it relates to the factors to be considered in the evaluation of sites, 15 16 which indicates that reactors should reflect through their design, construction, and operation an extremely low probability for accidents that could result in the release of significant quantities of radioactive fission products. In addition, 10 CFR Part 100, §100.10, indicates that the site location, in conjunction with other considerations, should insure ensure a low risk of public 17 exposure. Specific criteria necessary to meet the relevant requirements of 10 CFR Part 100, §100.10 are described in the following paragraphs: Offsite and onsite hazards which have the potential for causing onsite accidents leading to the 18 release of significant quantities of radioactive fission products, and thus pose an undue risk of public exposure, should have a sufficiently low probability of occurrence and be within the scope of the low probability of occurrence criterion of 10 CFR Part 100, §100.10. Specific guidance with respect to offsitesuch hazards is provided in Chapter 2, Section 2.2.3, of 19 Regulatory Guide (RG) 1.70 (Ref. 2). As indicated therein, the identification of design basis 20 21 events resulting from the presence of hazardous materials or activities on site and in the 22 vicinity of the plant is acceptable if the design basis events include each postulated type of accident for which the expected rate of occurrence of potential exposures in excess of the 10 CFR Part 100 guidelines is estimated to exceed the NRC staff objective of approximately 10-7 per year. Because of the difficulty of assigning accurate numerical values
