and anchor bolts, need to be preplanned, identified on the construction drawings, and documented on field changes to the drawings. This would permit verification that embedments have been placed with full consideration given to the resulting reduction in structural strengths, radiation shielding effectiveness, and hindrance to the placement and consolidation of concrete. Regulatory Position 13 provides guidance on this matter, in addition to the Code provisions. Regulatory Position 14 Ultimate Capacity of Concrete Containment GDC 50 in Appendix A to 10 CFR Part 50 requires a determination of the internal pressure capacity for containment structures, as a measure of the safety margin above the design-basis accident pressure. Regulatory Position 14 describes an acceptable methodology for determining the ultimate pressure DG-1372, Page 13 capacity of the concrete containment. RG 1.216 describes a deterministic methodology for estimating the ultimate pressure capacity of reinforced concrete and prestressed concrete containments. Regulatory Position 15 and 16 Code Cases Related to ASME Code, Section III, Division 2 Regulatory Positions 15 and 16 include active Section III Code Cases related to Division 2 that are acceptable or conditionally acceptable, respectively, to the NRC staff. These positions include Division 2 Code Cases that were inadvertently listed in RG 1.84, Revision 38, and any later Division 2 Code Cases published up to the release of the 2019 Edition of the ASME B&PV Code “Code Cases—Nuclear Components.” The 2019 Edition of the Code Cases includes Code Case actions issued through Supplement 7 to the 2017 Edition. Regulatory Position 17 Regulatory Position 17 includes active Section III Code Cases related to Division 2 that are unacceptable to the NRC staff. This position includes Division 2 Code Cases that were inadvertently included in RG 1.193, Revision 6, and any later Division 2 Code Cases issued up to the publication of the 2019 Edition of the
