, 3.3 The following is a listing of the weights of tne shipping cask and it's various components.
Cask with fuel 46,175# Personnel barrier 850# Outer closure head 340# Inner closure head 745# Top impact structure 865# Bottom impact structure 460# Lifting yoke with adaptor 2,062# 3.4 The' cask will contain spent fuel when it arrives on site, so care should be taken when loosening and removing the cask lid to minimize personnel exposure. 3.5 Use of unborated water over the spent fuel pool for purposes of rinsing off the cask and crane hook / cables is permissible.
! 3.6 The drumming area and auxiliary building ventilation system should be operable.
3.7 All loose material associated with this procedure is to be secured
; with lanyards when in close proximity to the spent fuel pool.
- ( '
3.8 Auxiliary building crane movements are governed by PBNP 3.4.5, "Special Structural Limitations on the Lifting of Heavy Loads." L 3.9 Do not immerse the cask in water which has a temperature of 100*F more ' or less than that of the cask surface to prevent thermally shocking the cask structure. 3.10 _The cask surface may not be cleaned with steel wool or any other abrasive material. No polishing of the cask exterior is permitted. 3.11 The cask trailer is light in weight and fragile. Extreme care must be taken when loading or unloading the cask to prevent damage to the trailer. Place wheel chocks on transporter when loading and [ unloading. 3.12 The cask exterior is constructed of one-fourth inch stainless sheet metal and care must be exercised when handling to prevent denting the l cask. 3.13 Exercise care when unloading fuel from the cask or installing closure heads to prevent scratching the flange "0" ring seating surfaces. ( 3.14 Ensure that the cask is vented prior to unbolting the inner closure head. k l
