摘要： PROBLEM TO BE SOLVED: To initially arrange particles simply and suitably even in a complicated analysis system. SOLUTION: A flow analysis device has a particle arrangement section 31, a structure shape input reception section 32, a lattice point setting section 34, a particle-in-structure determination section 35, and an initial arrangement particle decision section 36. The particle arrangement section 31 arranges particles at respective lattice points in a system divided in a lattice shape. The structure shape input reception section 32 receives the input of the shape of a prescribed structure formed by the particles arranged at the lattice points in the system. The lattice point setting section 34 sets an arbitrary point of the prescribed structure where the input of the shape is received, to one of the lattice points in the system. The particle-in-structure determination section 35 uses a prescribed lattice point in the set system to determine whether the particles arranged at respective lattice points in the system are those included in the prescribed structure. The initial arrangement particle decision section 36 decides particles to be arranged initially to form the prescribed structure at flow analysis start among the particles arranged at respective lattice point in the system, based on the decision result.

摘要： PURPOSE:To reduce pressure loss and flow turbulance in a value by smoothing flow in the valve. CONSTITUTION:A main steam isolation valve has a valve box 20 provided with a valve body 12 reciprocative which opens and closes fluid passages 21 to 23. An intermediate flow passage 22 has a sectional area which has an oval shape wherein a short axis is a reciprocating axis of the valve body 12 reflected on a plane perpendicular to a pipe axis of each of the fluid passages 21 to 23. When the valve is fully opened, the valve body 12 is not so exposed to the main flow passages. In addition, the flow passage is widened in a long axis direction to secure a flow passage sectional area. Generation of pressure loss is prevented in the valve, and turbulance of the flow is reduced.

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.

摘要： PURPOSE:To decrease stress generated by hydraulic force of fluid by making a circumferential edge of a reactor water flowing opening at a lower part of a shroud which is provided surroundingly a reactor core, in a nuclear reactor pressure vessel, coincide with an upper edge of the opening, and by making both curvatures of the circumferential edge and a bottom plate of the nuclear reactor pressure vessel coincide approximately. CONSTITUTION:In a bottom part of a nuclear reactor pressure vessel 1, a current plate 22 of which curvature is made to the same with that of a bottom plate of the nuclear reactor pressure vessel 1, is provided at a periphery of and along the bottom plate. In this case, reactor water discharged from a pump main part 11 of an internal pump, flows into a space between the bottom plate of the nuclear reactor pressure vessel 1 and the current plate 22 through a reactor water flow opening 16, and, from that place, passes through an opening 23 of the current plate 22 to flow into a shroud 2. Accordingly, flow of the reactor water flowing into the shroud 2 becomes approximately parallel to a control rod housing 19 and a stub tube 20, and therewith working moment of hydraulic force of fluid by the flowing-in reactor water and also stress, caused by the hydraulic force of fluid, decreases.
