A packaging system for radioactive waste is robust, highly functional, and can be used for nearly all radioactive waste streams that require shielded packaging. The packaging system includes a modular container that is configured to receive modular shielding inserts. The packaging system can be used to store, transport, and dispose of radioactive waste.

Method of using a modular container system for radioactive waste

A system and method for managing spent nuclear fuel includes a small capacity canister that preferably encloses or encapsulates a single spent nuclear fuel rod assembly but can enclose up to six spent nuclear fuel rod assemblies. The canister is air tight and prevents radioactive material from escaping. The canister is loaded by positioning a single spent nuclear fuel rod assembly in the canister and then closing the canister to make it air tight.

Detectors are used to monitor the status of spent nuclear fuel storage containers non-invasively while they remain in storage casks. The detectors measure neutron flux and &ggr;-ray flux and may also measure temperature variations of the spent nuclear fuel. The measurements can be accomplished actively or passively, with minimal exposure of individuals to radiation fields or other hazardous conditions. Preferred neutron and &ggr;-ray detectors have a semiconductor active region that is resistant to neutron damage. Incipient structural failures may also be detected using measurements based on electrical continuity, with data being transmitted to an external pickup coil.

In-situ self-powered monitoring of stored spent nuclear fuel

Disclosed is a transportation and storage assembly for transporting and storing nuclear fuel rod assemblies. The transportation and storage assembly includes a basket assembly (24) designed for failed nuclear fuel rod assemblies, or a basket assembly (122) designed for undamaged nuclear fuel rod assemblies. The basket assemblies (24, 122) are inserted into a canister (22). The canister (22) includes a shell (26) that receives and surrounds the basket assemblies (24, 122), and lids (28, 96) that enclose the shell (26). The basket assemblies (24, 122) include a plurality of apertured plates (36, 124) interconnected by structural members (42, 88) that maintain the plates (36, 124) in a spaced apart relationship, axially aligning the apertures (38, 126) in the plates (36, 124). In the basket assembly (24) for failed nuclear fuel rod assemblies, a container (44) is inserted into a row of axially aligned apertures (122), having a drain passage (104). In the basket assembly (122) for undamaged nuclear fuel rod assemblies, a plurality of guide sleeve assemblies (132) are formed from structural members (134, 138), and a layer (136) including a neutron poisoning material. The containers (44) and guide sleeve assemblies (132) are each for receiving a nuclear fuel rod assembly.
