Content:
are shared by multiple nuclear power units. 6. Compliance with GDC 50 requires that the reactor containment structure, including access openings, penetrations, and the containment heat removal system, be designed so that the containment structure and its internal compartments can accommodate, without exceeding the design leakage rate and with sufficient margin, the calculated pressure and temperature conditions resulting from any LOCA. This SRP section provides detailed acceptance criteria and cites appropriate regulatory guidance for design methodology, material testing, and construction techniques that are acceptable to the staff. GDC 50 requires that the internal structures of the containment be designed to withstand the effects of natural phenomena, combined with those of normal and accident conditions, including LOCA loads, without a loss of capability to perform their safety function. The load combinations and specifications cited in this SRP section provide acceptable engineering criteria to accomplish that function. Meeting these requirements and criteria provide assurance that the internal structures of the containment will perform their intended safety function with sufficient margin when subjected to LOCA loads in combination with other applicable loads. 7. Compliance with 10 CFR Part 50, Appendix B, requires that applicants establish and maintain a quality assurance program for the design, construction, and operation of SSCs. This SRP section provides guidance specifically related to design, construction, testing and inservice surveillance of structural concrete and steel of containment internal structures. Subsection II.2 of this SRP section cites ACI 349, with additional guidance 3.8.3-32 Revision 4 – September 2013 provided by RGs 1.142 and 1.199; ASME Code, Section III, Division 1, Subsection NE, and ASME Code, Section III, Division 2, Subsection CC, with additional guidance provided by RGs 1.57 and 1.136, respectively; ANSI/AISC N690-1994
