Abstract
Abstract A transport, storage, monitoring, and retrieval system for casks including intermediate storage of spent fuel rods from nuclear power plants. The system consists of a powered rail transport car which carries a cask standing on its end. A cross-ways traveling powered rail "under car" unit carries the rail transport car and loaded cask transversely on rails underneath to align with a bay rail which the powered rail car traverses to the cask storage location. Bridge cranes off-load the casks and with monitoring equipment perform remote cask inspections. Bay rails and a pair of cross-ways traveling "under car" units serve for movement of both the transport car and the bridge units. Casks are located automatically at specific addresses for inventory control and data logging of radioactive emissions. The system may operate remotely and cask conditions are monitored from automated retrieved collected at an off-site data base.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
181 words
A site transport, storage monitoring, and retrieval system for casks of spent nuclear fuel, comprising a field of rows of rail road trackage, surfaces between the rows for standing off-loaded casks for storage; transverse rail trackage and transverse traveling rail under-cars, said transverse rail trackage carrying said rail under-cars, said rail under-cars having an integral rail trackage affixed to the surface of their beds, said integral rail trackage can be aligned as an extension of any rail row and function to carry other cars from one row to another or to or from the field; one or more bridge cranes traversing field rails while spanning over one or more rows of rail; one or more cask carrying transport cars for traveling the field rails, said transport cars can be off-loaded or loaded while under a bridge crane; and said transport cars and bridge cranes communicating with the integral rails of positioned rail under-cars to move from sets of field rails to other sets of field rails or to commute with off-site locations to bring in or take out casks or equipment.
Claim 2
Dependent Claim
181 words
A site transport, storage monitoring, and retrieval system for casks of spent nuclear fuel, comprising a field of rows of rail road trackage, surfaces between the rows for standing off-loaded casks for storage; transverse rail trackage and transverse traveling rail under-cars, said transverse rail trackage carrying said rail under-cars, said rail under-cars having an integral rail trackage affixed to the surface of their beds, said integral rail trackage can be aligned as an extension of any rail row and function to carry other cars from one row to another or to or from the field; one or more bridge cranes traversing field rails while spanning over one or more rows of rail; one or more cask carrying transport cars for traveling the field rails, said transport cars can be off-loaded or loaded while under a bridge crane; and said transport cars and bridge cranes communicating with the integral rails of positioned rail under-cars to move from sets of field rails to other sets of field rails or to commute with off-site locations to bring in or take out casks or equipment.
Claim 3
Dependent Claim
23 words
Claim 1 and further having a bridge crane equipped with monitoring equipment to rove around the standing casks and check for contamination leakage.
Claim 4
Dependent Claim
20 words
The system of claim 2 and further having motors and control mechanisms such that the system can be operated remotely.
Claim 5
Dependent Claim
72 words
The system of claim 3 and further having an interfacing data base having equipment for receiving and maintaining location and status records for the casks and for receiving new inspection data, equipment to analyze the data, and equipment to use the analysis and determine defective conditions, and the system has equipment to generate alarms and initiate notifications that a problem or potential problem exists in the field when defective conditions are determined.
Claim 6
Dependent Claim
55 words
The system of claim 1 and further having locomotion power with pony locomotives, using one locomotive for powering a transport car and using a locomotive on each end to move a bridge crane or an under-car, the width of said under-cars being sufficient to accommodate both a transport car being moved and a pony locomotive.
Claim 7
Dependent Claim
26 words
The system of claim 2 and further having a bridge crane equipped with a bridge span width adjuster for adjusting the distance between the crane ends.
Claim 8
Dependent Claim
13 words
The system of claim 2 and further having an earthen berm for shielding.
