摘要： PROBLEM TO BE SOLVED: To reduce stress generating in a measurement pipe by suppressing the vibration of measurement pipes due to pressure pulsation.
SOLUTION: To the measurement pipe 17 connected with a diffuser 7 of a jet pump, a vibration suppressing device 19 constituted by connecting a cramp part 20 to a wing plate 21 by way of a connection part 22 is attached. When the measurement pipe 17 vibrates due to pressure pulsation during plant operation, owing to occurrence of friction between the measurement pipe 17 and the wing plate 21, vibration energy diffuses, attenuation of the vibration of the measurement pipe 17 increases and vibration response is suppressed. By this, the stress generated in the measurement pipe 17 can be relaxed.

摘要： PURPOSE:To decrease components which has possibility of becoming loose and to shorten the attachment and detachment time by fitting a diffuser directly to a boss part in a nuclear reactor pressure vessel without using any stretch tube. CONSTITUTION:Plural boss parts 2 penetrate the bottom part of the nuclear reactor pressure vessel 1 at equal intervals in the circumferential direction. The casing 5 of the motor part 4 of the internal pump 3 is fixed to each boss part 2. The lower end outside of the sleeve 14 of the pump 3 and the upper end outside of the boss part 2 of the vessel 1 have cuts 23 and 24 as welding margins over the entire circumference and those parts are welded 25 to fit the diffuser directly to the vessel 1. Consequently, no stretch tube is used for the fixation of the diffuser, so any dedicated jig, etc., is not required to reduce the possibility of loose parts, thereby shortening the attachment and detachment time.

摘要： PURPOSE:To prevent generation of any vibration and wear and enhance the reliability during opening/closing operation of the valve, by stabilizing the support of a valve body in the main steam isolation valve. CONSTITUTION:This valve has a valve casing 23 which is formed with a cylinder-shaped valve chamber 24 intersecting a substantially straight line connecting a primary flow passage 21 and a secondary flow passage 22, at a specified angle of inclination, both passages 21, 22 being disposed in a substantially linear manner. A valve body 25 is inserted into the valve chamber 24 of the valve casing 23, in the form of a piston. A drive mechanism 28 is provided for driving the valve body 25 at a high velocity. When the valve is fully opened, a portion of the valve body 25 covering from an intermediate portion to a tip end thereof is located in the flow passage. A sleeve holder 30 covering the outer surface of the valve body 25 is mounted at a valve-body accommodation position of the valve chamber 24 at the time when the valve is fully opened. The outer peripheral surface of the valve body 25 at least an intermediate portion thereof is made a small-diameter portion spaced apart from guide ribs 31a, 31b, 31c.

摘要： PURPOSE:To control the vibration of a valve body to contrive the improvement of reliability at the time of opening and closing operation by fixing a holding member detachably holding the valve body on a valve box when the valve body is wholly opened. CONSTITUTION:An outer taper 29b fitting an inner taper 23a of a valve body 23 is formed on the opening lower end part of a cylindrical main body 29a of a coupling 29 and an outer taper 29b is detachably fitted in an inner taper 23a of the valve body 23. Accordingly at the time of the wholly opening operation of the valve body 23, since its opening upper end part is detachably fitted in the coupling 29 and fixed on the valve box 22 through the coupling 29 and a flange 25 securing it, vibration is reduced even if its lower part is projected in a main steam passage. As the result, the friction with the valve body 23 and a central guide tab 28 caused for the vibration of the valve body and a pair of rear face guide tabs is reduced and fluid leakage can be prevented due to the reduction of these friction at the time of the wholly closing of a main steam separation valve 21.
