CONCRETE CONTAINMENTS REVIEW RESPONSIBILITIES Primary - Organization responsible for structural analysis reviews Secondary - None I. AREAS OF REVIEW The specific areas of review are as follows: 1. Description of the Internal Structures. The descriptive information, including plans and sections of the various internal structures, is reviewed to establish that sufficient information is provided to define the primary structural aspects and elements relied upon to perform the safety-related functions of these structures. To perform safety-related functions, these structures must be capable of resisting loads and load combinations 3.8.3-2 Revision 4 – September 2013 to which they may be subjected and should not become the initiator of a loss-of-coolant accident (LOCA). If such an accident were to occur, the structures should be able to mitigate its consequences by protecting the containment and other engineered safety features from the accident’s effects such as jet forces and whipping pipes. The major containment internal structures that are reviewed, together with the primary structural function of each structure and the extent of descriptive information required for each structure, are indicated below. This NUREG-0800, Standard Review Plan (SRP) section reviews the intervening structural elements between distribution systems including their supports (e.g., cable trays; conduit; heating, ventilation, and air conditioning; and piping and equipment supports) and building structural steel/concrete (e.g., steel platforms, building frame members, embedment plates, and building steel members beyond the jurisdictional boundary of supports to mechanical components). A. Pressurized-Water Reactor (PWR) Dry Containment Internal Structures i. Concrete Supports for Reactor The PWR vessel should be supported and restrained to resist normal operating loads, seismic loads, and loads induced by postulated pipe rupture, including LOCAs. The support and restraint system should
