11 [The impact of the accident extends to the outer periphery of the containment vessel throughout the interval. In particular, in the case of an accident involving high-temperature, high-pressure piping such as a main steam pipe, high-pressure steam may enter the gap and act as external pressure on the containment vessel, adversely affecting the structural integrity of the containment vessel. become. Therefore, in the past, in order to protect the containment vessel, a blowout panel was provided at the boundary of the space m housing the first penetration assembly e, and the steam pressure in this space m reached the allowable external pressure of the containment vessel. The blowout panel is first destroyed so that the steam escapes to other spaces, such as the inside of the reactor or the turbine building, and the pressure decreases. However, when this pressure drop exceeds the allowable external pressure of the containment vessel.

（防止を図る上できわめて有効である。Since the partition pipe 1r was provided at a position to partition between the telescopic outer pipe 1 and md#x, in the unlikely event that the pipe 1
Even if the rupture occurs on the outside of 0, the high-pressure steam, etc. that blows out is blocked by the partition pipe 11 and the telescopic outer tube 11, and does not flow into the containment vessel 14M.Therefore, external pressure due to the blowout steam, etc. acts on the containment vessel 1. Therefore, the structural integrity of the storage volume s1 can be maintained. Then, when the internal pressure of the space 21 on the side of the penetration part assembly 10 reaches a predetermined pressure, for example, the allowable external pressure of the partition pipe 1r or the telescopic outer pipe 11, due to the ejected steam, etc.
The pressure is exhausted by blowing through the blowout panel IJ
Escape to g@. Then, in this exhaust @ 211, the exhaust device 2a is activated, radioactive gas etc. are removed by the ) 1 router assembly 29, and clean exhaust gas is discharged to the outside of the Wi-reactor structure through the exhaust stack 11. Therefore, it is extremely effective in preventing exposure to radiation.

圧制御が容器になるという利点もある。Since the gap IS can be blocked by the partition 91xr and the inside of the 1st ward Entomi 11 can be kept in a sealed state, for example, by connecting a suction mechanism such as Pro 1 to the ward w121, the inside of the partition 1111 can be connected to the outside of the passageway. Negative pressure can be maintained in the space. Therefore, it is effective in preventing leakage of contaminated air to the outside, and there is also the advantage that the negative pressure control for air conditioning becomes a container.

Since the basic configuration is the same as that of the first embodiment, common parts are given the same reference numerals and explanations are omitted, and different parts will be explained below. That is, in this second embodiment, a concrete partition wall 1) is formed in one compartment 11, and a fixing device I for supporting the pipe I is attached to the pace plate aX provided on the partition wall 11, and Flange I
J and the annular receiver provided on the partition wall 11 provide a partition fJF! between the plate IJ and the partition wall 11. It is fixed airtight. That is, the above interval I
! 11, partition pipe IF, flange 12, etc. as a block, the containment vessel 1 is partitioned into an inner space 121 and an outer space xxb. Note that, similar to the first embodiment shown in FIG. 3, this outer air chamber 2jh is communicated with an exhaust chamber 2# equipped with an exhaust system 11 and a purifying device such as a filter assembly g1#. On the other hand, the inner space IIm is used as a maintenance area for the telescopic outer pipe 11 and the partition pipe 1r. Furthermore, a protective tube J4 is fixed to the plunger 12 inside the partition pipe JF, so that the partition pipe 1r can be protected from the impact that occurs when the pipe 1 is broken.

This method is effective in maintaining the structural integrity of the containment vessel, since the gas ejected from the piping breakage can be contained to a large extent. In addition, gas leaking from the piping is led to the exhaust chamber, where it can be purified and discharged, which prevents the pressure inside the building from increasing and prevents contaminated gas from being released outside the delamination. It is effective in preventing radiation exposure and preventing radiation exposure.
The effect is huge.
