A portable XRF analyzer includes a hand shield to substantially block x-rays from impinging on a hand of a user. The portable XRF analyzer includes a heat sink over an x-ray source and a heat sink over an x-ray detector. The heat sinks are separated from each other by a thermally insulative material.

A device for transferring a toxic substance from a dispensing vessel to at least one receiving vessel comprising: (i) a receiving portion arranged to receive a dispensing vessel containing a toxic substance; and (ii) a transfer apparatus having a first infusion line adapted for fluid communication with the dispensing vessel to transfer a carrier fluid into said vessel and a second infusion line having one end adapted for fluid communication to withdraw and transfer the carrier fluid and the toxic substance from the dispensing vessel and the other end of the second infusion line arranged to connect with the at least one receiving vessel.

A modularized system for processing, storing and/or disposing of a hazardous waste material is described. In one exemplary embodiment, the modularized system includes a container configured to sealingly contain hazardous waste material; a first cell, the first cell comprising a first area for manipulating the container; and a second cell, the second cell comprising a second area for manipulating the container. The second cell is isolated from the first cell. The first cell is held at a first pressure and the second cell held at a second pressure, the first pressure being less than the second pressure. An interlock couples the first cell to the second cell. The first cell, second cell and interlock are configured to allow the container to be transferred from the first cell to the second cell while maintaining at least one seal between the first cell and the second cell.

An apparatus is provided for storing hazardous waste material, which includes one or more of spent nuclear fuel, radioactive material, and fissionable material. A fusible alloy material, for example, a eutectic material, resides within the apparatus and surrounds the hazardous waste material. In the preferred embodiments, it is suggested that the fusible alloy material exhibits liquidus and solidus or melting temperatures that are between about 100 and 300 degrees Fahrenheit for facilities using the apparatus and methods for liquid storage pool loading applications. For facilities using the apparatus and methods for dry loading, the fusible alloy materials may exhibit liquidus and solidus or melting temperatures that are between about 100 and 650 degrees Fahrenheit. The fusible alloy material is introduced in a liquid phase and eventually solidifies into a solid phase as the temperature of the hazardous waste material and/or the local environment decreases.

This disclosure pertains to a holder for a radioactive source capsule with pivoting first and second parts, with redundant mechanisms for retention of the capsule during transportation and handling. These retaining mechanisms include a set screw in the first pivoting part to engage the capsule and to prevent radial movement of the capsule, a locking shelf in the second pivoting part to fix the axial orientation of the pivoting bottom end of the capsule holder, and a capture tooth within the capsule to prevent release of the capsule while in the shipping and/or handling tube of the capsule holder.
