摘要： A nuclear waste cask with impact protection includes impact limiters comprising deformable energy-absorbing perforated sleeves. An impact amelioration system for nuclear fuel storage components includes impact limiter assemblies at the bottom cask to canister interface including impact limiter plugs frictionally engaging corresponding plug holes formed in the cask closure plate. A nuclear waste fuel storage system includes an unventilated cask including a heavy free-floating radiation shielding lid loosely coupled the top end of the cask in a movable manner via the anchor bosses which provides cask over pressurization protection. A nuclear waste cask includes an axially elongated rectangular cuboid cask body having a cavity for holding nuclear waste materials and cask locking mechanism including first locking protrusions on the lid which are selectively interlockable with mating second locking protrusions on the cask body to lock the lid to the cask body.

摘要： A container includes a two-piece lid, a base, and an O-ring. The two-piece lid includes a plate and a connector including a first leg with internal threads and a second leg. The base defines a cavity with an open end and a closed end and includes a collar with external threads. The O-ring is configured to form a seal between the two-piece lid and the base. The internal threads on the first leg of the connector engage the external threads of the collar responsive to rotation of the two-piece lid relative to the base. The second leg of the connector drives the plate towards the base responsive to the internal threads on the first leg of the connector engaging the external threads of the collar. The O-ring forms the seal as the internal threads on the first leg of the connector engage the external threads of the collar

摘要： Elongate capsules for housing waste are configured for disposal (placement) into wellbore(s) that are located in particular deep underground geologic formation(s). These capsules have opposing structures for physically linking multiple capsules together in an end-to-end fashion. These opposing end structures may include a stinger with pins at a top end of the capsule; and a J-slots structure at the bottom end of the capsule. The stinger with pins of a first capsule may be (removably) attached to the J-slots of a second capsule. Further, a retrieval-tool also has the J-slots structure at one end. The J-slots structure of the retrieval-tool may be configured to (removably) attach to a stinger with pins of a given capsule (which may be linked to other capsule(s)); and then the retrieval-tool may be used to retrieve the given capsule(s) from a given wellbore. Capsule retrieval systems and/or method may utilize such capsule(s) and the retrieval-tool.

摘要： A system for transporting radioactive materials which may include a containment vessel, a thermal shield, and an impact limiter. The containment vessel may include a vessel body having a storage cavity for receiving radioactive materials, a lid coupled to an upper portion of the vessel body to enclose a top end of the storage cavity, and a lid seal such as a gasket positioned between the lid and the upper portion of the vessel body. The thermal shield may be positioned over the lid. The first impact limiter may be positioned over the thermal shield. The thermal shield may be resistant to high temperatures and may help to protect the integrity of the lid seal when the system is subjected to high temperatures, such as during a fire condition.

摘要： An air-cooled condenser system for steam condensing applications in a power plant Rankine cycle includes an air cooled condenser having a plurality of interconnected modular cooling cells. A method for forming an axial flow baffle for a shell and tube heat exchanger includes providing a baffle workpiece, locating a centerpoint of a first axial flow tube aperture, drilling flow holes around the centerpoint of the flow aperture, and drilling a central tube hole at the centerpoint. A method of cooling high level waste includes surrounding a cask comprising an external surface and an internal storage cavity containing the high level radioactive waste which emits heat with a cooling water header; and discharging cooling water radially inwards from the cooling water header onto the external surface of the cask from the plurality of water dispensing outlets arranged on the cooling water header.

摘要： The present invention relates to a transport basket for defective spent nuclear fuel of a heavy water reactor and, more particularly, to a transport basket for defective spent nuclear fuel of a heavy water reactor that can reduce the burden of a personnel when handling spent nuclear fuel in a test facility by minimizing a storage space and maximizing a thickness such that only a predetermined amount of spent nuclear fuel for soundness evaluation in the test facility can be transported. To this end, provided is a transport basket for defective spent nuclear fuel of a heavy water reactor, comprising: a basket body having a storage space and an internal support that partitions the storage space; a fuel pocket that is installed on one side of each storage space partitioned through the internal support and is installed so as to be rotatable toward the other side of the storage space, and has a detachable groove open in an upward direction such that a fuel case containing the spent nuclear fuel can be detached therefrom; and a cover that opens and closes the storage space of the basket body and is screwed to the basket body.
