Content:
ets, shell stiffeners (if any) in the hoop and vertical directions, and external cooling flow channels (e.g., AP600, AP1000). iii. The dome of the steel containment, including any reinforcement at the dome/cylinder junction, penetrations, and attachments to the inside and outside surface of the dome, such as supports for containment spray piping, any stiffening of the dome, and external cooling flow channels (e.g., AP600, AP1000). iv. The major penetrations, or portions thereof, of steel or concrete containments, to the limits defined by the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (hereafter referred to as the ASME Code), Section III, Division 1, Subsection NE. This includes portions of the penetrations that are intended to resist pressure but are not backed by structural concrete, sleeved and unsleeved piping penetrations, mechanical system penetrations such as fuel transfer tubes, electrical penetrations, and access openings such as the equipment hatch and personnel locks. v. The ice-condenser containments, with special emphasis on those areas that are unique to this type of design, such as the connection between the ice-condenser and the containment. vi. The BWR pressure suppression systems, paying special emphasis to piping that channels steam and air and is necessary for the containment function. This includes, but is not limited to, the torus, vent lines, vent header, equalizing ring header, and downcomers. In addition, the staff reviews the drywell/ventline junction, vent header/downcomers junctions, and penetrations to determine the expected behavior of the structure when subjected to the design loads. 2. Applicable Codes, Standards, and Specifications. The reviewer evaluates the information pertaining to design codes, standards, specifications, and regulatory guides (RGs), and other industry standards that are used in the design, fabrication, construction, testing, and inservice surveillance of the steel containment.
