Abstract: A ventilated overpack apparatus for containing a spent nuclear fuel canister has photon radiation scattering attenuators in the air ducts, preferably at or near the external openings. The apparatus preferably has straight ambient air inlet ducts and straight hot air outlet ducts which allow for improved rates of air flow and, because of the radiation scattering attenuators, far more efficient trapping of photons and reduced dose rates versus prior curvilinear or serpentine duct designs. The method of storing spent nuclear fuel comprises inserting a canister in the ventilated overpack apparatus which has the photon radiation scattering attenuators in the ducts. Preferably the top ducts are formed by three-sided channels in the sidewalls of the overpack and a fourth side formed by the flat bottom of the top lid, and the bottom ducts are also formed by three sided channels with the fourth side being formed in part by the bottom lid and in part by a concrete pad on which the overpack rests.

Abstract: An in-line roller skate propulsion device comprising a lever and a wheel frame having a top, a bottom, a plurality of wheel axle holes near the bottom, a pivot connection near the top for pivotally connecting the lever to the wheel frame, and a hole and shaft combination for connecting a resilient member. The lever's pivot connection is located forward of the center of the lever. As the lever rotates around its pivotal connection to the wheel frame, the resilient member is stretched. Upon release of the rotating force, the resilient member returns the lever to a point of contact with the wheel frame or a stopping piece attached thereto. This action allows a skater to achieve greater speeds than with regular in-line roller skates while exerting the same amount of energy.
