Title: Containment vessel drain system

Abstract

A system for draining a containment vessel may include a drain inlet located in a lower portion of the containment vessel. The containment vessel may be at least partially filled with a liquid, and the drain inlet may be located below a surface of the liquid. The system may further comprise an inlet located in an upper portion of the containment vessel. The inlet may be configured to insert pressurized gas into the containment vessel to form a pressurized region above the surface of the liquid, and the pressurized region may operate to apply a surface pressure that forces the liquid into the drain inlet. Additionally, a fluid separation device may be operatively connected to the drain inlet. The fluid separation device may be configured to separate the liquid from the pressurized gas that enters the drain inlet after the surface of the liquid falls below the drain inlet.

  • A system is disclosed for cooling the atmosphere in a primary containment vessel containing a reactor pressure vessel and for removing radioactive and non-radioactive water-soluble gases and dusts floating in the atmosphere of the primary containment vessel by the arrangement which comprises a gas treating casing, a blower connected to the casing, and duct sets connected to the blower. The gas treating casing contains a water-spray device for spraying cooling water in the casing, a heat exchanger located downstream of the water-spray device, a moisture separator located downstream of the heat exchanger, and a device for removing drain from themore » casing.« less
  • This patent describes a monitoring system for monitoring at least one drain valve disposed in a fluid conduit having a temperature affected by the presence of fluid flow, and producing a diagnosis of the condition of each drain valve as functional, clogged or stuck shut, stuck open, or cold fluid flow through the drain valve. It comprises: at least one flow sensor, each flow sensor including a heater attached to an exterior surface of the fluid conduit downstream of the drain valve, drain valve position indicator means for producing and outputting a signal indicative of a selected position for eachmore » corresponding drain valve, operating condition indicator means for producing and outputting a signal indicative of an operating condition of the steam turbine, and control means responsive to the output signals of the operating condition indicator means, the differential temperature producing means, and the drain valve position indicator means, for outputting a signal indicative of a diagnosis of the drain valve.« less
  • This patent describes an automatic transmission mechanism comprising a first and a second hydraulic pressure actuated friction engaging device. The gear transmission mechanism provides a certain lower speed stage when the first friction engaging device is engaged by supply of actuating hydraulic fluid pressure thereto and the second friction engaging device is disengaged by non supply of actuating hydraulic fluid pressure thereto. The gear transmission mechanism also provides a certain higher speed stage when the first friction engaging device is disengaged by non-supply of actuating hydraulic fluid pressure thereto and the second friction engaging device is engaged by supply ofmore » actuating hydraulic fluid pressure thereto, a hydraulic fluid pressure control system, comprising: a speed shift valve having a first, a second, a third, a fourth, and fifth port;a downshift timing valve having a first port passage; an upshift timing valve having a second port passage, a sixth port, and a third valve element driven by a throttle pressure from a fifth position toward a sixth position against a force applied by a fluid pressure supplied to the sixth port; a first hydraulic pressure system for operating the first friction engaging device in relation to the second friction engaging device; and a second hydraulic pressure system for operating the second friction engaging device.« less
  • A temperature actuated drain system is provided that comprises a siphon that has an inlet end for immersing in a pool of water to be drained from a roof surface and a discharge end communicating with a pressure-responsive one-way valve. A solar actuated enclosed chamber that contains a solar heat energy collector is located on the roof surface and is in open communication with the siphon by means of a tubular member that has its inlet end positioned closely adjacent the bottom of the interior of the chamber. The arrangement causes any appreciable amounts of water that accumulate within themore » chamber to be discharged from the chamber during the pumping action created by the heating and cooling of air within the chamber.« less
  • A solar energy system is described comprising: a storage tank having upper and lower sections. The tank lower section is for holding a heat transferring liquid and the tank upper section is for holding a gas; a solar collector located above the storage tank and having a collector feed and a collector return wherein a first one of the collector feed and return couples to the lower section of the storage tank; a pump coupled to the lower section of the storage tank and to a second one of the collector feed and return. The pump exhibits an active statemore » in which the pump moves a portion of the liquid into the solar collector and exhibits an inactive state; and means for preventing a portion of the gas from substantially replacing the liquid in the collector until a predetermined amount of time passes after the pump initially exhibits the inactive state. The preventing means are located above the storage tank and the preventing means have a drainback feed coupled to the solar collector and a drainback return coupled to the upper section of the storage tank.« less
