is" on those areas which are unique to this type of design such as the connection between the ice-condenser and the containment. (vi) The containment of floating nuclear power plants are reviewed with 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 channel steam and air, and are 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 penetra- tions are reviewed to determine the expected behavior of the structure when subjected to the design loads. 2. Applicable Codes, Standards, and Specifications The information pertaining to design codes, standards, specifications, and regulatory guides, and other industry standards that are used in the design, fabrication, construction, testing, and inservice surveillance of the steel containment, is reviewed. The specific editions, dates, or addenda identified for each document are also reviewed. 3. Loads and Loading Combinations Information pertaining to the applicable design loads and various load combinations is reviewed with emphasis on the extent of compliance with Subsection NE of the Code, Section'Ill, Division 1, and with Regulatory Guide 1.57 (Ref. 2). The loads normally applicable to steel containments include the following: a. Those loads encountered during preoperational testing. b. Those loads encountered during normal plant startup, operation, and shutdown, including dead loads, live loads, thermal loads due to operating temperatures, and hydrostatic loads such as those present in pressure-suppression containments utilizing water. c. Those loads to be sustained during severe environmental conditions, including those induced
