DG-1372, Page 7 B. DISCUSSION Reason for Revision This revision (Revision 4) updates the guidance to endorse, with exceptions, the 2019 edition of the ASME B&PV Code, Section III, Division 2 (American Concrete Institute (ACI) Standard 359-19), “Code for Concrete Containments” (Ref. 25), hereafter referred to as “the Code” or “the ASME Code.” The significant changes include updated concrete material and mix design provisions for resistance to alkali-silica reaction and improved durability; incorporation of more recent material standards for reinforcing steel; new design provisions requiring radial tension reinforcement in portions of prestressed concrete containment susceptible to delamination; provisions allowing use of mechanically headed deformed bar anchorages, additional types of mechanical splices for reinforcement; and the addition of slip test and slip acceptance criteria for mechanical splices which improve constructability and safety. This revision of the guide also addresses the acceptability of the Section III Code Cases related to Division 2 of the ASME B&PV Code, Section III. The Division 2 Code Cases addressed in this RG include those listed in RG 1.84, Revision 38,
