摘要： PURPOSE:To fix a cover without welding by forming a seal structure capable of water sealing on the main body of an access hole cover. CONSTITUTION:An access hole cover 20 to close an access hole 15 penetrated in a shroud support plate 9 supporting a shroud is combined to the plate 9 with a stud bolt 21. At the bottom of the cover 20, a groove 22 is formed to seal the hole 15 from water and a metal O ring 23 is arranged as a seal part in the groove 22. To make the treatment of the cover 20 easy, a handle 24 for crane hook up is provided on it. Thus, the closing is possible without welding the plate 9 and the hole 15, and corrosion of crevice is prevented because of the avoidance of welding.

摘要： PURPOSE:To prevent damage to equipment to be carried out or in, by arranging a stationary member temporarily retained with a stud bolt erected on the top surface of a flange of a pressure vessel of a nuclear reactor and a guide member held on the stationary member. CONSTITUTION:When a shroud head with the outer diameter almost close to the inner diameter of a pressure vessel of a nuclear reactor, a steam dryer or the like is hung down within the pressure vessel of the nuclear reactor, a groove of a bracket of equipment lowering is retained with the tip of a guide cap 28 and subsequently, guided to a guide rod 16 along the guide cap 28. The tip of the guide cap 28 is arranged at a height almost the same as that of a stud bolt 24 thereby eliminating fear of damage to the guide cap 28 in contact therewith 24 even when the equipment suspended oscillates before the groove of the bracket is engaged with the guide cap 28.

摘要： PROBLEM TO BE SOLVED: To drive a control rod at an optimal speed during operation and inspection of a nuclear reactor. SOLUTION: An induction motor 35 is used as a motor. A 60 Hz fixed- frequency power supply 44 and a variable-frequency power supply 45 are individually provided as power sources for supplying electric power to this induction motor 35. During the operation of a nuclear reactor, the fixed-frequency power supply 44 is connected. During the sloppage of the nuclear reactor stoppage, the variable-frequency power supply 45 is connected. During the inspection, a control rod is driven at a high speed by electric power of a high frequency for shortening the inspection time. During the control rod friction test, the control rod is driven at a low speed by electric power of a low frequency for accurately performing the test.

摘要： PURPOSE:To prevent fuel damage caused by transitional boiling by arranging a grid plate around an outlet part of a jet pump. CONSTITUTION:At the nuclear reactor in this invention, a grid plate 10 is attached to an outlet part of a jet pump 8. By this sort of arrangement, foreign objects can be captured by the grid plate 10 provided at the outlet part of the jet pump 8, in the case the foreign objects are mixed into a coolant flow path in a nuclear reactor pressure vessel 1. Accordingly, in the case that even though the foreing objects are mixed into the coolant, possibility of fuel damage caused by transitional boiling resulted from shortage of the coolant in a reactor core, can be diminished.
