摘要： A method of storing a chimney assembly of a reactor pressure vessel during a nuclear reactor outage includes detaching a chimney barrel with upper chimney partitions therein from a top guide assembly of the reactor pressure vessel. A height of the upper chimney partitions is less than a height of the chimney barrel so as to leave a plenum region in a top section of the chimney barrel. The top guide assembly includes lower chimney partitions therein. The lower chimney partitions are removed from the top guide assembly and inserted into the plenum region of the chimney barrel so as to be on the upper chimney partitions. As a result, the chimney assembly can be stored in a relatively compact form during a reactor outage. The chimney assembly includes a combination of at least the chimney barrel, the upper chimney partitions, and the lower chimney partitions.

摘要： Chimneys include several combinable parts useable in nuclear reactors. The parts are modular and removably joinable without destruction for use in directing flow in an operating nuclear reactor and directly fit in storage area during non-operation. Chimney parts are joinable through flanges and connecting structures. Chimney parts may include partitions that divide or direct energetic coolant flow from a nuclear core as well as steam separating and drying structures. The parts each individually fit within storage areas of the nuclear plant, including equipment or buffer pools in the refueling floor of the plant. Methods move the chimney parts between the reactor and storage areas, and multiple parts may be stacked or nested in such moves. Methods are useable underwater and with storage pools to prevent exposure of chimney parts during an outage. During operation, chimneys are useable in place of existing single-piece chimneys.

摘要： A reactor pressure vessel assembly may include a housing (H) surrounding a reactor core (112), steam separators (118), and a chimney (108). Inner surfaces of the chimney and reactor core define a conduit for transporting a two phase flow stream from the reactor core through the chimney to the steam separators. The housing defines an opening. An inner surface of the housing and outer surfaces of the chimney and reactor core define an annulus in fluid communication with the opening and conduit. A feedwater sparger (126) in the housing (H) is connected to the at least one opening and configured to deliver a sub-cooled feedwater into the annulus. A flow barrier structure (134) between the chimney and the steam separators may force mixing between the sub-cooled feedwater and a downcomer fluid from the steam separators. An outer steam separator may be vertically over a portion of the flow barrier structure in a plan view.

摘要： Seals 250, 250a, 250b are positioned between abutting nuclear reactor components 102, 118, 120. Example seals 250, 250a, 250b are held in position by gravity, grooves 102a, 102b, retainers 415, direct joining, or other mating structures to seal the abutting components. Compression of example seals 250, 250a, 250b drives the seals 250, 250a, 250b against the joining components, preventing fluid passage therebetween. Example seals 250, 250a, 250b may include a cavity opening 252 to a higher pressure fluid outside the joined components to drive expansion or sealing of the seal. Seals 250, 250a, 250b may have a C-shaped, E-shaped, O-ring, coiled, helical, or other cross-section to provide such a cavity. Example seals 250, 250a, 250b may be flexible materials compatible with radiation and heat encountered in a nuclear reactor. Seals 250, 250a, 250b may be continuous or sectional about the abutment of the components. An annular seal 250b may extend continuously around a perimeter of removably joined core plates, supports 102, shrouds 114, and/or chimney heads 122 and structures. Seals can be installed between and in the components at any time access is available to the components.
