n the plant that have a potential to become a significant high radiation area (greater than 1 Gy (100 rads) per hour) or a very high radiation area during operations and AOOs. These areas include, but are not limited to, those exposed to gamma shine from steam 12.3-12.4-26 Revision 5 – September 2013 components in BWR designs (both onsite occupational and offsite public exposure concerns); areas providing access to the spent fuel transfer tube during fuel transfer; the below-vessel reactor cavity, in certain PWR designs, with in-core thimble tubes withdrawn; the upper drywell, in BWR designs, during fuel movements, and areas adjacent to the reactor vessel and containment sump pumps used for meeting TS leakage detection instrument requirements. Appendix B to RG 8.38 includes guidance on some of these areas. 4. For the OL FSAR, the reviewer will consider any changes in the design that might necessitate changes in operating procedures to accommodate a changed radiation zone or a different location of equipment. 5. The reviewer will determine whether the applicant has followed the guidance of the referenced RGs and industry standards, both by comparison of the applicant’s methods with the information in the guides and by the applicant’s reference to any such guides or to proposed alternatives. The reviewer will evaluate whether the alternatives are equivalent to, or improvements on, the methods cited in the referenced RGs. Otherwise, alternatives are likely to be disapproved. 6. Based on the review, the health physics staff may request additional information or request the applicant to reevaluate the radiation protection design features to meet the acceptance criteria of Subsection II of this SRP section. 7. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the FSAR meets the acceptance criteria. DCs have
