摘要： A mixing apparatus for a plurality of turbulently flowing fluid flows varying in temperature and/or composition includes a mixing chamber having a non-circular or predetermined cross section and a straight or curved center line. A plurality of single-conduit and parallel or radial deflector elements are disposed beside the mixing chamber and staggered in the direction of the center line. The deflector elements receive a fluid flow being oriented at an angle relative to the center line and staggered laterally. The deflector elements deflect the fluid flow tangentially into the mixing chamber. The mixing chamber has an outlet opening for the exit of a mixed fluid flow. In a gas-cooled, high-temperature nuclear reactor with a circular outline, the mixing apparatus has a horizontal, annular mixing chamber with a plurality of sectors. Horizontal annular conduits receive at least one fluid flow. A plurality of vertical conduits are disposed above the sectors and have upper ends connected to the horizontal annular conduits and lower ends connected to the mixing chamber. An outlet opening communicates with the mixing chamber. The sectors havie a plurality of bores formed therein in the vicinity of the outlet opening for receiving absorber material.

摘要： 949,778. Feedwater distributers for steam boilers. A. HUET. Feb. 29, 1960 [March 9, 1959], No. 7119/60. Heading F4A. [Also in Division G6] In a nuclear reactor steam producing plant, the heat exchanger through which the reactor coolant passes, possesses a number of parallel paths which have equal fluid resistance in order to maintain identical thermal conditions in each path. As shown, the columns a are supplied with heat exchange fluid from the main duct b through the distribution centre c, tubes e 1 , e 2 , e 3 and secondary distribution centres f 1 , f 2 , f 3 . Discharge of the heating fluid is effected through the ducts I and m in which the bellows n allow for thermal expansion of the tubing. Water may be supplied to the boiler and steam withdrawn therefrom by way of networks of conduits such as those described above.

摘要： A metal conduit assembly for interconnecting the discharge duct of the pump and the inlet coolant duct or reactor core in a pool-type nuclear reactor. The conduit assembly comprises an upper section for connection to the discharge of a reactor pump, a lower section for connection with the coolant inlet duct with reactor core and a third intermediate tubular section for interconnecting the other two sections. Joint means are provided for interconnecting one end of the intermediate section with an adjoining end at the upper section and an opposite end of the intermediate section with an adjoining end of the lower section. The joint means comprises a male portion having a ridge provided with a circumferential groove for receiving a seal means and an associated female portion having an inside diameter greater than that of the ridge for receiving said male portion and a seal means. A key aspect of the conduit assembly is the seal means which comprises a split cylindrical piston ring having overlapping ends to provide for radial expansion and compression of the seal means.
