n through all environmental and abnormal loadings such as earthquake, and impact due to spent fuel cask drop, drop of a spent fuel assembly, or drop of any other heavy object during routine spent fuel handling. The major structural elements reviewed and the extent of the descriptive information required are indicated below. (a) Support of the Spent fuel Racks: The general arrangements and principal features of the horizontal and the vertical supports to the spent fuel racks should be provided indicating the methods of transferring the loads on the racks to the fuel pool wall and the foundation slab. All gaps (clearance or expansion allowance) and sliding contacts should be indicated. The extent of interfacing between the new rack system and the old fuel pool walls and base slab should be discussed, i.e., interface loads, response spectra, etc. If connections of the racks are made to the base and to the side walls of the pool such that the pool liner may be perforated, the provisions for avoiding leakage of radioactive water of the pool should be indicated. (b) Fuel handling: Postulation of a drop accident and quantification of the drop parameters are reviewed by the Accident Evaluation Branch (AEB)Emergency Preparedness and Radiation Protection Branch (PERB); Structural Engineering 125 Branch Civil Engineering and Geosciences Branch accepts the findings of the 126 AEBPERB review for the purpose of review of the integrity of the racks and 127 the fuel pool including the fuel pool lines due to a postulated fuel handling accident. Sketches and sufficient details of the fuel handling system should be provided to facilitate this review. 3.8.4-35 DRAFT Rev. 2 - April 1996 (2) Applicable Codes, Standards, and Specifications Construction materials should conform to Section III, Subsection NF of Ref. 3.1. All materials should be selected to be compatible with the fuel pool environment to minimize corrosion and galvanic effects. Design, fabrication, and installation of spent
