Content:
shell is reviewed, including major structural attachments such as beam seats, pipe restraints, crane brackets, and shell stiffeners (if any) in the hoop and vertical directions. (iii) The dome of the steel containment, including any reinforcement at the dome/cylinder junction, penetrations or attachments made on the inside such as supports for containment spray piping, and any stiffening of the dome. (iv) Major penetrations or portions thereof, of steel or concrete containments, to the limits defined by Subsection NE of the ASME Boiler and Pressure Vessel Code (hereafter "the Code"), Section III, Division 1 (Reference. 1) , and portions of the penetrations that are intended to resist 6 pressure but are not backed by structural concrete, including those of sleeved and unsleeved piping penetrations, mechanical systems penetrations such as fuel transfer tubes, electrical penetrations, and access openings such as the equipment hatch and personnel locks. (v) The ice-condenser containments are reviewed with special emphasis on those areas which are unique to this type of design, such as the connection between the ice-condenser and the containment. (vi) The containments of floating nuclear power plants are reviewed with 7 special emphasis on the connection between the platform and the containment, between the containment and the ice-condenser, and associated penetration piping. (vii) The BWR pressure suppression systems are reviewed with special attention on those piping which channels steam and air and areis8 necessary for the containment function. Such items include, but are not limited to, the torus, the vent header, the equalizing ring header, and the downcomers. Also, the drywell/vent header junction, the vent header/downcomers junctions, and the penetrations are reviewed to determine the expected behavior of the structure when subjected to the design loads. 2.
