An underground ventilated system for storing nuclear waste materials. The system includes a storage module having an outer shell defining an internal cavity and an inner shell. A majority of the height of the outer shell may be disposed below grade. The outer shell may include a hermetically sealed bottom. First and second canisters are positioned in lower and upper portions within the cavity respectively in vertically stacked relationship. A centering and spacing ring assembly is interspersed between the first and second canisters to transfer the weight of the upper second canister to the lower first canister. The assembly may include centering lugs which laterally restrain the first and second canisters in case of a seismic event. A natural convection driven ventilated air system cools the canisters to remove residual decay heat to the atmosphere. In one non-limiting embodiment, the shells are made of steel.

A neutron capture therapy system includes a neutron generation device for generating a neutron beam, an irradiation room for irradiating an irradiated body with the neutron beam and a placement table that is accommodated in the irradiation room and is adapted to support the irradiated body. The placement table includes a placement member for supporting a patient, an adjustment device for adjusting a spatial position of the placement member, a driving rod connected between the adjustment device and the placement member and a first shielding member covering the adjustment device. The first shielding member prevents the adjustment device from being radiated by radioactive rays. The adjustment device is disposed in the first shielding member that is basically sealed, thereby greatly reducing radiation damage to the adjustment device by neutrons and gamma rays and prolonging the service life of the adjustment device.

A radiographic inspection device and a method of inspecting an object are provided. The radiographic inspection device includes a support frame, where an inspection space applicable to inspect an object is formed within the support frame, and the inspection space has a first opening connecting to an outside; a transfer mechanism applicable to carry the object to move through the inspection space; a shielding curtain mounted at the first opening; and a driving mechanism mounted on the support frame and configured to drive the shielding curtain to move, so as to open or close the first opening. Since the driving mechanism drives the shielding curtain to rise or fall, it is possible to ensure that the lightweight object for inspection may smoothly enter the inspection space for subsequent radiographic scanning.

A system for controlling the position of an articulated robotic arm includes a robotic catheter procedure system having the articulated robotic arm and a controller coupled to the articulated robotic arm. The system further includes a patient table positioned proximate to and separate from the articulated robotic arm and a tracking system coupled to the controller and configured to measure a change in a position of the patient table. The controller is configured to adjust the position of the articulated robotic arm based on the measured change in position of the patient table.

An automatic reloading and transport system for solid targets for a particle accelerator using a pneumatic tube transport system from the point of target activation by a particle accelerator to a target processing point and back, comprising a pneumatic tube transport system with end stations for receipt and dispatch of a capsule accommodating the target, a handling mechanism for both manipulating the solid target and handling the capsule and a target positioning system.
