摘要： PURPOSE:To prevent the failure of the MI cable at the time of a high temp. by fitting a platinum alloy flange onto the base end of a winding frame and fitting the same into a connecting fitting and making the armor pipe of an MI cable of a platinum alloy. CONSTITUTION:A temp. measuring platinum strand 2 is wound on the outer peripheral surface of the blind cylindrical winding frame 1 made of alumina and a positioning hole 4 is hollowed at the root end of the winding frame 1. The MI cable 9 houses platinum alloy core wires 8 interposed with an inorg. insulating powder material 7, such as MgO, in the platinum alloy armor pipe 6. This cable 9 is fitted into the hole 4. The cap-shaped platinum alloy flange 17 is fitted onto the root end of the winding frame 1 and a joining material 28 is packed and fixed therein to braze and join the flange 17 to the connecting fitting 16 made of 'Hastelloy X'. The flange 17 has the coefft. of thermal expansion approximate to the coefft. of thermal expansion of the winding frame 1 and thermally elongates and contracts in the same manner as the cable 9. The failure of the MI cable is, therefore, prevented at the time of a high temp.

摘要： PURPOSE:To allow the decrease of the oscillation of a winding frame and to prevent the failure of a cable connected to the temp. measuring platinum strand at the base end of the winding frame by supporting the front end of the winding frame with the front end of a holding cylinder via a supporting member or directly supporting the front end of the winding frame. CONSTITUTION:The temp. measuring platinum strand 2 is wound on the outer peripheral surface of the winding frame 1 and a positioning hole 4 is hollowed in the central axial direction of bottom at the base end of the winding frame 1. Connecting holes 5, 5 to connect the hole 4 and the winding end are bored. The end face of the MI cable 9 which houses platinum alloy core wires 8, 8 interposed with an inorg. insulating material 7, such as MgO, in an armor pipe 6 consisting of a platinum alloy is subjected to end face sealing 10 and the core wires 8, 8 are exposed from the seal 10. The core wires 8, 8 are inserted into the communicating holes 5, 5 and the cable 9 is fitted into the positioning hole 4. Both ends of the strand 2 and the front ends of the core wires 8, 8 are connected. The strand 2 is then coated with a coating material and enmal is packed into the cavity between the core wires 8 and 8 to closely seal the cavity. The increase in the spacing is obviated by a thermal elongation difference even if the sensor heats up to a high temp. at the time of use. The oscillation of the winding frame 1 is thus limited.

SOLUTION: In a fast breeding reactor using lead or lead bismuth as coolant, the coolant is heated by fission energy generated in a reactor core 1, raises the high temperature coolant, which is heated, and has a higher temperature than an average temperature and lower density than average density of entire coolant in a nuclear reactor vessel 2, to an upper side of the nuclear reactor vessel 2 is raised by natural convection, and at a vapor generator 4 provided on the upper side of the nuclear reactor vessel 2, heat is exchanged between the high temperature coolant and water, and the water is converted into vapor, and the high temperature coolant is cooled. Low temperature coolant which is cooled and has a lower temperature than the average temperature and higher density than the average density of the entire coolant in the nuclear reactor vessel 2 is lowered to the reactor core 1 by the natural convection. Thereby, the coolant is naturally circulated in the nuclear reactor vessel 2 and the reactor core 1 is cooled.

摘要： PURPOSE:To absorb the difference in elongation at the time of a high temp. with a platinum flange and to prevent the failure of an MI cable by parting the joining point between the platinum alloy flange and the root end of a winding frame at a required distance in an axial direction from the joining point of the flange and the connecting fitting. CONSTITUTION:The outer peripheral surface of the winding frame 1 is metallized and the platinum alloy flange 17 is fitted onto this surface and is joined by a high-temp. brazing material 18. An accepting hole 19 of the connecting fitting 16 and the outer peripheral surface of the flange 17 are brazed by a gold/nickel/palladium brazing material 21. The joining point of the brazing material 21 is so determined as to be parted by the distance l in the axial direction from the joining point of the brazing material 18. The MI cable 9 and the connecting fitting 16 are brazed by a gold/nickel/palladium brazing material 22 in an insertion hole 20. The distance l is thus provided between the joining points in such a manner, by which the displacement by thermal expansion is escaped by the bending of the flange 17 and the generation of the stress by the direct thermal elongation difference in the winding frame 1 and the joint part is obviated.

摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of a thermal unbalance to a rotor through prevention of inflow of wet steam and to prevent the generation of rotor vibration. SOLUTION: A number of balance holes 75 are peripherally formed in the rotor disc 79 of the final stage moving blade 74 of a steam turbine. A flow guide 77 from an exhaust chamber from which steam flows out is supported at a support member 80, and a gland part 81 is mounted on the lower end of the support member 80. A cavity 78 consists of the support member 80, a blow guide end, and the disc 79. Wet steam penetrates through an opening part 82, a drain flows in a rotor 73 to locally cool the rotor, and temperature distribution of the rotor is rendered uneven. However, an L-shaped and semicircular steam inflow preventing plate 1 is mounted, penetration of steam and drain are prevented from occurring to the rotor part, a thermal unbalance of the rotor is prevented from occurring, and vibration due to the thermal unbalance is prevented from occurring.
