By the way, such a reactor containment vessel made of concrete has a simple structure, and the reactor containment vessel itself has sufficient strength and rigidity, so piping, etc. can be supported by this reactor containment vessel. It has its advantages. In the conventional system, as shown in Figure 2, piping 9, for example, main steam piping 5, is supported in the reactor containment vessel through piping penetration devices. In other words, 1 is a penetrating three! It is provided to penetrate the containment vessel main body 1 and the liner 2, and is fixed to the containment vessel main body IK by anchors 8 . . . and anchor grate #. The main steam pipe 5 is inserted through the through sleeve f1 with a gap therebetween. A closing support member 1# is provided at the end of the through-sleeve 10 on the outside of the reactor containment vessel (on the right side in Figure 2). 5 is airtightly closed, and this main steam pipe 5 is supported by a through sleeve fFK. Therefore, the axial load and torsional load generated on the main steam pipe 5 due to thermal expansion etc. are absorbed by the closing support member 10 and the penetrating sleeve 1.
It is supported by the containment vessel main body 1 via. However, in such a structure, the load of the main steam piping 5 is transmitted to the containment vessel main body 1 by the anchors 8 ... medium anchor grate 9 of the penetrating sleeve 1, so the containment vessel main body 1 has local A load will be applied. 19. Since high temperature steam flows through this main steam pipe 5, the heat is conducted to the through hole IJ-2 through the closure support member 10,
It is also transmitted to this penetrating sleeve 7 by radiation and convection. For this reason, the temperature of the penetrating three 17 increases, and the temperature of the surrounding containment vessel main body 1 also increases, which may cause the strength of the concrete to decrease. Therefore, the integrity evaluation of the containment vessel body 1 in the vicinity of the piping penetration devices becomes more difficult, and special reinforcement must be provided in the vicinity of the piping penetration devices. ,
Conventionally, a heat insulating material 1 was interposed between the main steam pipe I and the through sleeves fi, but the effect was insufficient. Moldy, this cooling pipe is cold! 31i1 is also used to prevent direct temperature rise of the through sleeve FO, but
Something like this has a complicated structure and may have problems such as '&'.

Honji @ Mori It is something that can be done based on circumstances beyond that, and that is 0.
The first target is the concrete reactor containment hall O.
It is possible to obtain a piping penetrating device that does not give any negative effects and has a simple structure.The following is a summary of the actual facts in Sections 3 and 4. According to the theory, 101 in m is located in the reactor □゛ containment capacity, built on the mat 101, and the inside of the reactor 1 10- is KjlK, and ζO reactor containment vessel 5.

This containment vessel main body 104 has a strength of 11% and has pressure resistance and radiation shielding ability. 9. The liner 1ea is formed from a relatively thin steel plate and provides airtightness. The reactor containment vessel 101 is constructed so that the pressure within the reactor containment vessel 101 increases and the reactor containment vessel 101 is not deformed by this pressure even when the reactor containment vessel 1040 is heated. First, on the inner surface of the ζ6 liner 101, there is a reinforcing member 1 made of lid steel or the like.
j a- is installed and the containment vessel body 1tj4
Due to the difference in thermal expansion between F-0 and O, this liner receives a load, which prevents local deformation of the F-0 liner. The interior of the ζO Fushi reactor containment vessel 9181 is divided into upper and lower sections by a Meyer frame floor of 1mgpc, with the upper part being a dry well 101, the lower part 11 having a t-prep horn 1y channel A1eaK shape, and the ζO reactor containment vessel 010.

The configuration of this pipe penetration device 1110 will be explained below. In the figure, reference numeral 111 denotes a through sleeve, which has a cylindrical shape. The penetrating sleeve 111 is inserted into the containment vessel main body 104 and passes through the containment vessel main body J#4) and the liner 1#ξ in an airtight manner. And this O through sleeve J I J
The end portion on the side of the inside of the O reactor containment vessel II (left side in Figure 114) is led out by a predetermined length 1. A main steam pipe 111 is inserted into the through sleeve 111, and a gap for cooling expansion is formed between the outer peripheral surface of the main steam pipe 111 and the inner ring of the through sleeve 111. There is. A closing support @@III is provided at the end 11 in the reactor containment vessel of this penetration space 9-fll#0. This closure support member 1

During the load in the direction of the round axis, the screw load occurs on the closed support part #11a.
The pipe support A111... and the mounting fixing member 11 are transmitted through the penetrating three flllfc.
11 # e 1 j O* 1 j It is transmitted to the reinforcing member 1ex of the liner 101 via O, and finally distributed and transmitted to the storage capacity main body 104. Note that this example has a d iso-whib structure 12J.
A part of the load of the main steam pipe 1110 is also transmitted to the Δide whip stock cha XXX at O in which connecting bases 9 connecting members JJJ... are provided. After a while,
Since the load of the main steam piping 111 is distributed over a wide area of the containment vessel body 1040, the load does not act on the containment vessel body soaKlhm in the vicinity of the through sleeve 118, thereby ensuring the health of the containment vessel body 104. In this embodiment, insulation concrete 124 is provided around the circumference 8 of the penetrating sleeve jlR, so that the O heat from the main steam pipe 111 is transferred to the surrounding area.
This prevents O from being transmitted to the containment vessel main body 104, and reduces the negative impact on the integrity of the reactor containment vessel 101t without causing a decrease in strength due to temperature rise. As mentioned above, a load generated in the main steam piping 111 is transmitted to the storage capacity main body 104 via the fixed pipe JJ#, 1190110, 110, and the through three f
Since no load acts on the J J IO circumference ■, there is no problem even if a cut IIIk tsuntarito with a strength of O is placed in the ζ0 portion.
