  • Patent number: 11721445
    Abstract: A replacement thermal sleeve with a flange for a reactor vessel closure head penetration adapter housing. By altering a diameter of the flange, a replacement thermal sleeve can be installed through the narrow diameter of the penetration adapter housing opening from under the reactor vessel head. The flange can be compressible or expandable or the tubular wall of the thermal sleeve can be inserted in longitudinal sections, one at a time, into an opening in the underside of the penetration head adapter and reformed within the opening when fully inserted.

  • Patent number: 11721444
    Abstract: Arrangements and devices for reducing and/or preventing wear of a thermal sleeve in a nuclear reactor are disclosed. Arrangements include a first structure provided on or in one the thermal sleeve and a second structure provided on or in the head penetration adapter. At least a portion of the first structure and at least another portion of the second structure interact to resist, reduce, and/or prevent rotation of the thermal sleeve about its central axis relative to the head penetration adapter. Devices include a base for coupling to a guide tube of the reactor and a plurality of protruding members extending upward from the base. Each member having a portion for engaging a corresponding portion of a guide funnel of the thermal sleeve.

  • Patent number: 11189386
    Abstract: A method of replacing a damaged thermal sleeve in a reactor vessel head adapter that connects a control rod drive mechanism to a reactor vessel head includes the steps of accessing the damaged thermal sleeve, removing the damaged thermal sleeve, and obtaining a replacement thermal sleeve having an elongated tubular body, a flanged region, and a plurality of slots defined in the elongated tubular body, each slot having a width which is sufficient to narrow a maximum outside diameter of the flanged region from a first diameter to a second diameter. The method further includes altering the maximum outside diameter of the flanged region on the replacement thermal sleeve, inserting the replacement thermal sleeve into an opening of a tubular member from an underside of the reactor vessel head, and expanding the maximum outside diameter of the flanged region into a recess of the reactor vessel head adapter.

  • Patent number: 8568664
    Abstract: An ozone generation system includes a plurality of modular ozone generating devices, each having an upper and lower housing. The upper housing encloses electrical components for providing high energy power to ozone generator cells of each device to produce an ozone generation output. The lower housing is formed by a multiplicity of section layers enclosing the ozone generator cells and an internal liquid coolant system. Each ozone generator cell has two plasma generation pathways. An orifice is formed in on each one ozone generator cell for maintaining a known and controllable pressure drop across each ozone generator cell. A plurality of ports formed in a center body framing element of the lower housing provides porting for the water in and out, oxygen in and ozone out. The modular devices can be combined on racks having a common manifold system for forming a rack of ozone producing devices for outputting a high yield of ozone.
