Title: Nuclear reactor container
Inventor: WATAKABE HISATO
IPC: G21C1/02
Filed: 1991-12-11
Abstract: PURPOSE:To transfer reactor core cooling members even when an earthquake breaks out by providing a sloshing liquid level regulating means such as partition plates for dividing, a baffle plate for converting direction, and a trap for generating a liquid dropping time delay, at the upper part inside an upper plenum, so as to regulate the liquid level. CONSTITUTION:Reactor core cooling member is accumulated in an upper plenum 3, and a free liquid level 1 is formed there. When an earthquake breaks out, and a sloshing is generated in an atomic reactor, the ratio of the span length of spans and the amplitude of the wave is made three times of the case of no partition plate 2a because the liquid level is divided into three by the partition plates 2a, and a nonlinear effect is to be generated at 1/3 amplitude, reducing the liquid level drop remarkably. Then, the inclination of a baffle plate is made 45 deg., and the scattering liquid drops from the inside of the plenum 3, and together with a flow moving upward along the plenum wall, the liquid level effect is reduced. Furthermore, a time delay is generated when the liquid drops by providing a trap, and thereby, the liquid level drop is reduced. Consequently, the reactor core cooling member can be transferred even when an earthquake breaks out.

Patent JP-H06173981-A (JP)
Title: Friction plate
Inventor: YAGI WATARU
IPC: F16D69/02
Filed: 1992-12-08
Abstract: PURPOSE:To prevent peeling-off by providing a main body composed of an aluminum alloy base composite material including an inorganic material smaller in thermal expansion coefficient and higher in heat resistance strength than an aluminum alloy as a reinforcing member, an intermediate layer composed of an alloy having a smaller thermal expansion coefficient and a corrosionproof effect, and abrasion resistant coating layer made of a material having a thermal expansion coefficient smaller than the intermediate layer. CONSTITUTION:A main body 2 is composed of an aluminum alloy base composite material including an aluminum alloy as a matrix and an inorganic material smaller in thermal expansion coefficient and higher in heat resistance strength than the aluminum alloy as a reinforcing material. An intermediate layer 3 of an alloy having a thermal expansion coefficient smaller than that of the reinforcing material is interposed between the main body 2 and a coating layer 4. Accordingly, a difference in thermal expansion coefficient between the coating layer 4 and the main body 2 is reduced so that the strength of the main body 2 can be secured in the atmosphere of high temperatures. Since the intermediate layer 3 is composed of an alloy including chromium, titanium and the like having a corrosionproof effect, electrodialysis is difficult to occur even if water or salt adheres to the interfaces, thus preventing corrosion. Consequently, such a danger can be prevented that the coating layer 4 is peeled from the main body 2.
