CONCRETE CONTAINMENTS (REINFORCED AND PRESTRESSED)

Systems, Structures, and Components This section addresses the elements of pressurized water reactor (PWR) concrete containment structures. Concrete containment structures are divided into three elements: (i) concrete, (ii) steel, and (iii) prestressing systems.

System Interfaces Functional interfaces include the primary containment heating and ventilation system (VII.F3),

containment isolation components (V.C), and the containment spray system (V.A). Physical interfaces exist with any structure, system, or component that either penetrates the containment wall, such as the main steam (MS) system (VIII.B1) and the feedwater (FW) system (VIII.D1), or is supported by the containment structure, such as cranes (VII.B). The containment structure basemat typically provides support to the nuclear steam supply system components and containment internal structures.

II B2-1 B2 MARK II CONTAINMENTS Systems, Structures, and Components This section addresses the elements of boiling water reactor (BWR) Mark II containment structures. Mark II steel containments are discussed in II.B2.1. Mark II concrete containments are discussed in II.B2.2.

System Interfaces Functional interfaces include the primary containment heating and ventilation system (VII.F3),

containment isolation components (V.C), and the standby gas treatment system (V.B). Physical interfaces exist with any structure, system, or component that either penetrates the containment wall, such as the main steam (MS) system (VIII.B2) and the feedwater (FW) system (VIII.D2), or is supported by the containment structure. The containment structure basemat may provide support to the nuclear steam supply system components and containment internal structures.

SAFETY-RELATED AND OTHER STRUCTURES Safety-related structures are those defined pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.4(a)(1), and the other structures are those defined pursuant to 10 CFR 54.4(a)(2) and 10 CFR 54.4(a)(3). Structures in this section are organized into nine groups and are discussed separately under subheadings A1 through A9.

III B.

COMPONENT SUPPORTS Component supports include supports for American Society of Mechanical Engineers (ASME) piping and components; supports for cable trays, conduit, heating, ventilation, and air conditioning (HVAC) ducts, TubeTrack, instrument tubing, non-ASME piping and components; anchorage of racks, panels, cabinets, and enclosures for electrical equipment and instrumentation; supports for emergency diesel generator (EDG) and HVAC system components; and supports for platforms, pipe whip restraints, jet impingement shields, masonry walls, and other miscellaneous structures.

GROUP 1 STRUCTURES (BOILING WATER REACTOR BUILDING, PRESSURIZED WATER REACTOR SHIELD BUILDING, CONTROL ROOM/BUILDING)

Systems, Structures, and Components This section addresses the elements of the boiling water reactor (BWR) reactor building, pressurized water reactor (PWR) shield building, and control room/building. For this group, the applicable structural elements are concrete, steel, and masonry walls. The aging management review (AMR) is presented for each applicable combination of structural element and aging effect.

System Interfaces Physical interfaces exist with any system or component that either penetrates the structure wall or is supported by the structure wall, floor, and roof. The direct interface is through the system or component supports that are anchored to the structure. Structures also protect housed systems or components from internal and external design basis events. In the case of tanks, there is a functional interface with the associated system. Water-control structures are integral parts of the systems that provide plant cooling water and residual heat removal.

GROUP 5 STRUCTURES (FUEL STORAGE FACILITY, REFUELING CANAL)

Systems, Structures, and Components This section addresses the elements of the fuel storage facility and refueling canal. For this group, the applicable structural elements are identified: (i) concrete, (ii) steel, and (iii) masonry walls. The aging management review (AMR) is presented for each applicable combination of structural element and aging effect.

System Interfaces Physical interfaces exist with any system or component that either penetrates the structure wall or is supported by the structure wall, floor, and roof. The direct interface is through the system or component supports that are anchored to the structure. Structures also protect housed structures and components from internal and external design basis events. In the case of tanks, there is a functional interface with the associated system. Water-control structures are integral parts of the systems that provide plant cooling water and residual heat removal.

SUPPORTS FOR ASME PIPING AND COMPONENTS Systems, Structures, and Components This section addresses supports and anchorage for American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) piping systems and components. It is subdivided into Class 1 (III.B1.1), Class 2 and Class 3 (III.B1.2), and Class MC (III.B1.3). Applicable aging effects are identified and the aging management review (AMR) is presented for each applicable combination of support component and aging effect.

System Interfaces Physical interfaces exist with the structure, system, or component being supported and with the building structural element to which the support is anchored. A primary function of supports is to provide anchorage of the supported element for internal and external design basis events so that the supported element can perform its intended function.

SUPPORTS FOR EMERGENCY DIESEL GENERATOR, HEATING, VENTILATION, AND AIR CONDITIONING SYSTEM COMPONENTS, AND OTHER MISCELLANEOUS MECHANICAL EQUIPMENT Systems, Structures, and Components This section addresses supports and anchorage for the emergency diesel generator (EDG) and heating, ventilation, and air conditioning (HVAC) system components, and other miscellaneous mechanical equipment. Applicable aging effects are identified and the aging management review (AMR) is presented for each applicable combination of support component and aging effect.

System Interfaces Physical interfaces exist with the structure, system, or component being supported and with the building structural element to which the support is anchored. A primary function of supports is to provide anchorage of the supported element for internal and external design basis events so that the supported element can perform its intended function.
