摘要： A control rod drive shaft guide (10) comprises an annular shaped body (12) to be inserted through a hole in a guide structure card (32) and having spring loaded arms (40) pivotally mounted in the body (12). The arms (40) snap outwardly to retain the guide in place. The guide has an exterior groove (18) to receive removal tooling, which tooling can engage release tabs (52) to cause retraction of the arms (40) to permit removal of the guide (10) from the card (32).

摘要： PURPOSE: To facilitate positioning of each cluster guide in a coolant flow separator by providing a cluster guide equipped with an outer casing having no hole for an upward flow of the coolant. CONSTITUTION: The attachment 12 comprises a collection assembly 19 having a plurality of guide pipes 21 for collecting a coolant and directing toward an output nozzle, a control cluster 10 interposed between the collection assembly 19 and a core 6, and a drive shaft guide. The attachment 12 further comprises a lower plate 24 provided with a passage for the coolant from the core 6, an ipper plate 27 provided with a passage for the coolant flowing toward the collection assembly 19, an enclosure and a separator 22. Furthermore, the cluster guide 23 of the flow separator 22 is provided with an outer casing 35 coupled to the coolant tightly with the upper and lower plates 24, 27 having no hole 25 and each guide pipe 21. The guide pipe 21 is provided with a side wall having no hole 28 within the assembly 19 and each guide pipe 21 is formed on the underside of a cover 3 and provided with an opening for feeding the coolant from the flow-in nozzle 4 into the volume section.

摘要： PURPOSE:To reduce the pressure loss at the recycling time, by means of setting up a by-path line of a mechanical type pump at a coolant recycling system, and of setting up a cheque valve on the downward piping part of the line. CONSTITUTION:A by-path line 7 thereat a mechanical type recycling pump 5 of the first cooling device is by-passed, is set up, and a cheque valve 8 is set up on the downward piping of this line. At normal operation, the valve body of the cheque valve 8 is closed, but when the mechanical recycling pump 5 is tripped or sticked, the discharging pressure of the pump 5 becomes null, the valve body of the chaque valve 8 being released by gravity, coolant is natural recycled the line of a reactor 1 a middle heat exchanger 3 a bypath line 7 the reactor 1, thereby the pressure loss of the bypath line 7 can be reduced, and the recycling ability can be enlarged.
