摘要： PURPOSE:To enhance the reliability of the at-reactor isolation cooler so that the stable operation is assured by cooling and supplying the branched cooling water which is branched from the discharge side of an at-reactor isolation cooling pump and cools the lubricating oil for apparatus at the time of reactor isolation. CONSTITUTION:This device has the at-reactor isolation cooling pump 2 which injects the cooling water stored in a condensate storage tank 4 or a pressure control pool 5 to a reactor pressure vessel 1 at the time of the reactor isolation to supply the branched cooling water branched from the discharge side of the pump 2 to a lubricating oil cooler 6, thereby cooling the lubricating oil for apparatus. The radioactive steam discharged from the apparatus is condensed by the branched cooling water in a condenser 7. The branched cooling water supplied to the lubricating oil cooler 6 and the condenser 7 is cooled by a branched cooling water cooler 18 to which a cooling medium is supplied from a cooling medium supply device 19. The branched cooling water supplied to the lubricating oil cooler 6 is sufficiently cooled by the branched cooling water cooler 18 and, therefore, the temp. of the lubricating oil is maintained at a low temp. even if the temp. of the stored cooling water rises at the time of the reactor isolation by a loss of coolant.

摘要： PURPOSE:To enhance the reliability of a main steam separation valve when opening or closing the valve and reduce stress generated at the root portion of a support by reducing vibration of the valve element. CONSTITUTION:In a main steam separation valve comprising a valve box 11 in which a valve element 12 for opening and closing a fluid passage is freely slidably installed, a fixed wall 26 which installs the valve element 12 in the valve box 11 when the valve element 12 is fully opened is provided within the valve box 11. The length of the valve element 12 is reduced to the point that the upper end of the valve element 12 can be put inside the fixed wall 26 when the value is fully closed.

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.

摘要： PURPOSE: To prevent deviation between the axes of a pump and a motor without being influenced by the pump operation temperature in a pump for high temperature and high pressure use.
CONSTITUTION: Under normal temperature, pump 2 is installed so that its axis of rotation coincides with that of an electric motor. When the temperature of the fluid handled by pump 2 rises, electric motor supporting base 4 expands due to the heat of the high temperature water discharged from the pump nozzle. Also, the heat transferred from the pump casing is transferred to pump supporting base 5, causing its thermal expansion. To equalize the amounts of thermal expansion between electric motor supporting base 4 and pump supporting base 5, the degree of opening is set for valve 8, which is provided in the cooling water pipe branched from the cooling water pipe connected to cooler 7 used for mechanical seal 3 of pump supporting base 5. By this, the adjustment of the axis of rotation of pump 2 operated at the time of its installation can be maintained the same regardless of the change of temperature of the fluid handled by the pump.
