RP Section 3.8.5, Subsection II.5. B. Any sliding and tilting motion will be contained within suitable geometric constraints such as thermal clearances, and any impact resulting from the clearances is incorporated. The fuel pool structure should be designed for the increased loads that stem from the new and/or expanded high-density racks. The fuel pool liner leak-tight integrity should be maintained, or the functional capability of the fuel pool should be demonstrated. 7. Materials, Quality Control, and Special Construction Techniques The applicant should describe materials, quality control procedures, and any special construction techniques; the sequence of installation of the new fuel racks; and the precautions to be taken to prevent damage to the stored fuel during the construction phase. If connections between the rack and the pool liner are made by welding, the welder, as well as the welding procedure for the welding assembly, should be qualified in accordance with the applicable code. 3.8.4-33 Revision 2 - March 2007 For spent fuel pool racks fabricated from aluminum, American Society of Civil Engineers, Suggested Specification for Structures of Aluminum Alloys 6061-T6 and 6067-T6 and “Specification for Aluminum Structures” (issued by The Aluminum Association) contain the guidance regarding material properties.
