可11ヒf(かあった。On the other hand, since the heat transfer capacity of this liquid metal hr+ is extremely low, the temperature of the wall of the nuclear power vessel in contact with this coolant IJ is extremely low compared to the temperature change of the coolant outside. However, the temperature of the wall above the liquid level of the reactor vessel's back cooling system fl 4A does not follow the temperature change of the coolant. 1θl, as in the case of H1q stop,
When the temperature changes for the first time in 2011, a large temperature difference occurs between the part of the reactor vessel below the coolant liquid level and the part below the liquid level. Along with this, there is a large temperature gradient on the wall of the reactor vessel in recent years, causing excessive thermal stress to occur. Nauuka 11hif (Kaita.

炉容器に伝わるのを防止づることか提案されている。Therefore, near the liquid level on the inner wall of the reactor vessel, there is a -C around the entire circumference.
The inner wall liner that forms the gas tank, which is the waste space, is installed to prevent direct contact between high-quality coolant and the inner wall of the reactor vessel. It has been proposed to prevent this from being transmitted to the furnace vessel.

た。FIG. 1 shows a conventional bubble pump, and the conventional example will be explained with reference to FIG. The bubble pump is composed of a gas injection tube 1 that blows waste under the liquid surface, and a pumping tube 2 that improves the two-phase flow of bubbles and liquid. In addition, in order to improve the pumping performance of the pump, it is possible to generate a large amount of small air bubbles.
Examples are known in which the gas outlet 3 is a multi-hole nozzle or a porous sintered metal is used. Furthermore, pumping pipe 2'
In order to guide as many air bubbles as possible to the F part, a skirt 4 is installed (in some cases, it is installed. Also, in order to pump out as much liquid as possible, the inner diameter of the pumping pipe 2 is set to several Cl1l), so it is 10 cm. There are bubbles of various sizes in the pumping pipe 2, or a mixture of bubbles in the pumping pipe 2.
The pumping head of C' is determined by the balance between the two-phase head in the pumping pipe 2 and the water pressure head below the liquid level 5.The conventional bubble pump C' has a pumping head of The maximum limit was about 2 to 3 ff4C of water depth.

かできる。``Summary of the Invention'' The pumping bubble pump according to the present invention has the following features: ``A nozzle that blows out waste on the liquid surface is inserted into the pumping pipe, and an A-refice resistance is provided at the part where the liquid flows into the pumping pipe. The structure is such that even if the pressure difference between the front and back of the refit is large, the inflow can be suppressed. By appropriately controlling the amount of waste blown in, the composition ratio (small id ratio) between the amount of waste and liquid in the pumping pipe can be freely changed, and the proportion of liquid in that composition ratio can be kept small. The total pressure (Het) inside the pumping pipe is lowered, and even if the head is small due to the water 1+J applied from the outside, the mixture of scum and one substance in the pumping pipe is pushed upward by the head pressure, making it possible to pump liquid even at small water depths. It is a bubble pump. This bubble pump is provided with an inner wall liner over the entire inner circumference of the inner wall surface of the reactor vessel, and between the free liquid level of the internal coolant KM 1lii-1-/Jl and the part below the free liquid level and the inner wall surface. A cassdam is formed as a gas space, and an installation tool C is formed to pump out the coolant accumulated in this cassdam to prevent the coolant from accumulating in the cassdam. It is possible to isolate it from

こともiiJ能となる。Next, an operation of pumping out liquid according to this embodiment will be explained. When waste is injected from the waste injection pipe 1, the bubbles 6 and liquid 10 in the pumping pipe 2 rise and are discharged from the waste pipe 19. When the liquid 10 is discharged, the pressure inside the pumping tube 2 decreases accordingly, the liquid enters from the orifice hole 8 at the lower end, and the liquid level 5- inside the pumping tube 2 rises by -LWl. When the liquid level 5' in the tube is above the waste spout 3, a piston-shaped liquid is pumped up by the injected gas and formed in the tube 2, and this liquid is ejected from the upper back, and this phenomenon is repeated. By appropriately adjusting the diameter and number of the orifice holes 8, the inflowing liquid m can be adjusted, and the pressure head inside the pumping pipe 2 can be reduced by controlling the gas flow. , it is also possible to obtain a head that is 10 times greater than the water depth.
