In Chapter 14, John D. Stevenson discusses the Code for concrete reactor vessels and containments. Requirements for concrete reactor vessel construction are contained in Subsection CB of Section III, Division 2. However, this Subsection of the Code is no longer being actively maintained. Requirements for concrete containment construction are contained in Subsection CC of Section III, Division 2.

John distinguishes between the confinements and the containments aspects of construction, and he discusses the containments addressed by the Code that are, in fact, secondary containments and act as final barriers to radioactive releases to the environment. John deals with the interface of ASME and ACI Codes and design basis requirements for containment design and construction. There is a section that briefly describes of the construction requirements, techniques, and procedures developed by the joint ACI 359 and ASME B&PV Code Section III, Division 2, Subsection CC Committee for concrete containments. Drawing from his wealth of professional experience, John addresses the stipulations for both BWRs and PWRs, and he provides both a historical and a global perspective on this aspect of the Code.
