A downhole tool system may include one or more containers to hold waste product and a tractor to convey the one or more containers to a storage location within a wellbore. The downhole tool system may also include an anchor to seal against the wellbore and secure the containers at the storage location. Additionally, the downhole tool system may include a disconnect tool to separate the tractor from the containers such that the tractor may be removed from the wellbore while leaving the containers at the storage location.

There is provided a vacuum volume reduction system having a volume reduction assembly of a fluid fill assembly coupled to a station wall of a vacuum tube vehicle station, to reduce a volume, under vacuum, in the vacuum tube vehicle station, when a vacuum transport tube vehicle is positioned in the volume at the vacuum tube vehicle station. The fluid fill assembly includes one or more containers, each containing a fluid, and fluid transport member(s), to transport the fluid from the container(s) to one or more enclosed volume portions formed between an exterior of the vacuum transport tube vehicle and an interior of the station wall. The fluid fill assembly further includes one or more fluid pump assemblies attached to the fluid transport member(s), and a control and power system. The vacuum volume reduction system further includes recessed area(s), a vent-to-vacuum assembly coupled to the recessed area(s), and seal elements.

Composition, manufactures, and processes of making and using them, consisting essentially of a neutron absorbent, having a neutron absorption cross section greater than or equal to Boron comprising at least 19.7% of Boron-10 isotope, and a thermal conductor having a thermal conductivity of at least 10% of water thermal conductivity at 100 degrees C. at sea level, combined such that the particles have a density of at least 0.9982 g/mL and not more than 2.0 g/ml. The composition can be located for release responsive to a loss of normal heat sink event and/or a loss of normal coolant event in a quantity sufficient, to palliate the loss of the normal heat sink event and/or the loss of normal coolant event.

A nuclear waste-capsule may include: an outer shell; an inner tube, located in that outer shell; and one or more spent nuclear fuel (SNF) assemblies (or portions thereof), with particular structure(s) attached thereto, within that inner tube. The particular structure(s) may be one or more spring-loaded receptacles (SLRs), such that each of the one or more SNF assemblies (or portions thereof), within the given inner tube, may have circumferentially attached thereto at least one SLR. Each such SLR may act as shock absorbing suspension means and may structurally support and centralize its associated SNF assembly (or portion thereof) within the given inner tube. Additionally, the one or more SNF assemblies (or portions thereof), along with the associated SLRs, may be immersed within a protective/preventative medium, within the given inner tube. The so loaded waste-capsule may be deposited within a wellbore that is located within a repository geological formation.

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 overpressurization 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.

A mobile reactor radiation shielding solution prevents activation of structural materials to reduce a radiation dosage risk to living organisms and accelerates timetables for transport. The shielding solution can include: in-vessel neutron shield, in-vessel shadow shield, transport shield, and module shadow shield. In-vessel neutron shield reduces and prevents the activation of the structural materials and significantly reduces the need for heavy shielding to shield against the gamma emissions from activated structural materials. In-vessel shadow shield provides neutron and gamma shielding between the reactor and a balance-of-plant (BOP) module and control system. In-vessel shadow shield is placed near the active nuclear core to minimize size of the shield while maximizing the protected arc to shield radiation workers while preparing the nuclear reactor for transport. Transport shield is used during transportation when living organisms come into proximity of the reactor. Module shadow shield shields reactor control components and BOP module during operation.
