Abstract
A blowdown manifold for a nuclear power plant includes a main conduit section, at least one coolant exhaust conduit, and at least one fluidic device. The main conduit section is connected to a pressure relief system in the nuclear power plant. The coolant exhaust conduit has a first end coupled to the main conduit section and a second end extending into a receptacle. The fluidic device is in fluid communication with the main conduit and exhibits a lower flow resistance to air than to water and steam.
Claims23
A blow-down manifold for a nuclear power plant, comprising:
- a main conduit section in fluid communication with the pressure relief system in the nuclear power plant;
- at least one fluid exhaust conduit having a first end coupled to said main conduit section and a second end extending into a receptacle;
- and
- at least one fluidic venting device in fluid communication with said main conduit section and operatively connected thereto in parallel with said fluid exhaust conduit, wherein said fluidic device presents a first flow resistance to air and a second flow resistance, higher than the first flow resistance, to a fluid other than air for venting air from said manifold.
A blowdown manifold connected to pressure relief system piping in a nuclear power plant, comprising:
- manifold means for receiving primary coolant flow from the nuclear power plant and directing the primary coolant flow therethrough;
- exhaust piping means for receiving the primary coolant from the manifold and directing the primary coolant into a receptacle;
- dual resistance flow means, in fluid communication with said manifold means and positioned so as not to be immersed in the primary coolant, for presenting (1) a first flow resistance to air and (2) a second flow resistance to the primary coolant, wherein the second flow resistance is higher than the first flow resistance for venting air from said manifold means.
