and operate nuclear power plants. These documents are made available to the public as part of the Commission's policy to inform the nuclear Industry and the general public of regulatory procedures and policies, Standard review plans are not substitutes for regulatory guides or the Commission's regulations and compliance with them is not required. The standard review plan sections are keyed to the Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants. Not all sections of the Standard Format have a corresponding review plan. Published standard review plans will be revised periodically, as appropriate, to accommodate comments and to reflect new informa- tion and experience. Comments and suggestions for Improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission, Office of Nuclear Reactor Regulation. Washington, D.C. 20555. calculated whole-body and thyroid doses at the exclusion area (EAB) and the low populaton zone (LPZ)-boundaries are well within the exposure guideline values specified in 10 CFR Part 100, paragraph 11 (Ref. 1). Well within is defined as 25% of-the 10 CFR Part 100 exposure guideline values or 75 rem for the thyroid and 6 rem for whole-body doses. A technical specification is required for the leak rate from the primary to secondary coolant system in the steam generators. This specification is acceptable if the calculated potential radiological consequences from the control rod ejection accident are within the exposure guidelines above. The models for calculating the whole-body and thyroid doses are acceptable if they incorporate the appropriate conservative design batis assumptions outlined in Appendix B to Regulatory Guide 1.77 (Ref. 2) with the exception of the guidelines for the atmospheric dispersion factors (X/Q values). The acceptability of the X/Q values is determined under SRP Section 2.3.4. III. REVIEW PROCEDURES The reviewer selects and emphasizes specific aspects of this appendix to
