An apparatus for supporting spent nuclear fuel. The apparatus may include a basket apparatus that is designed to be inserted into a cavity of a container or cask. The basket apparatus may be formed by arranging a plurality of slotted plates in an intersecting manner. The slotted plates may form fuel cells for storing fuel assemblies with spent nuclear fuel rods therein and flux trap spaces between adjacent ones of the fuel cells. Furthermore, the apparatus may include reinforcement members positioned in the flux traps to increase the structural strength of the basket apparatus.

An apparatus having an x-ray source and an x-ray detector configured to be rotated about a standing patient to capture and store a plurality of radiographic images of the patient during the rotation. A portable enclosure surrounds the source, the detector and the patient.

The present disclosure relates to a shield cover for a radiation source machine and a security inspection apparatus. The shield cover for a radiation source machine comprises: a frame body provided with a receiving chamber for receiving the radiation source machine, an end opening and an ray exit through which rays are emitted out from the radiation source machine; an end cover disposed at the end opening of the frame body and provided with a sealed chamber communicating with the receiving chamber; and a connecting member disposed between the end cover and the frame body and provided with an opening for communicating the sealed chamber of the end cover with the receiving chamber of the frame body, and the end cover being movably connected to the frame body by the connecting member such that a distance of the end cover from the end opening of the frame body is adjustable.

In general, radiation shielding systems that shield radiation from multiple directions are described. In one embodiment, a method of shielding radiation is provided, including supporting a shielding device on an object proximate a radiation source, positioning a first shielding portion in a vertical position relative to the object, positioning a second shielding portion to extend away from the first portion, the second shielding portion attached to the first portion, and shielding radiation from the radiation source by the first shielding portion and the second shielding portion such that the first and second shielding portions provide a radiation shielding zone for a healthcare practitioner.

Hydrophobic filter materials, methods of making them, and their use in various industrial applications are presented. In an example, thermally stable, gas permeable hydrophobic filters which maintain their integrity upon exposure to elevated temperature, radiation, acid, or all are described.

A storage apparatus with radiation shielding for spent nuclear fuel includes a fuel basket comprising elongated fuel storage tubes each defining an open cell configured to hold a nuclear fuel assembly. Gamma radiation attenuation inserts are nested inside at least some of the storage tubes. The inserts each comprise elongated open-ended tubular bodies which may have a rectangular cuboid configuration with square cross section. The inserts are composed of a dense metallic material selected for blocking gamma radiation and may have high thermal conductivity for effective heat dissipation from the decaying nuclear fuel. Attenuation inserts can occupy some or all perimeter tubes to provide shielding against gamma radiation emanating in a lateral direction from the fuel basket. The inserts may include upper and lower securement features for detachable fixation to the storage tubes, and air/gas flow cutouts.
