Abstract

<P>PROBLEM TO BE SOLVED: To obtain a low-pressure chamber of a fallout shelter type, which is not only reduced pressure training facilities for specific athletes but also a low-pressure chamber that can be used daily by ordinary users, equipped with neutron shielding functions for protecting life from a large quantity of neutrons generated in nuclear fission reaction. <P>SOLUTION: The problem is solved by the low-pressure chamber of a fallout shelter type which is characterized by the shielding from neutrons generated in nuclear fission reaction by making an enclosure of the low-pressure chamber out of neutron shielding or by covering the outer periphery of the enclosure of the low-pressure chamber with neutron shielding. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The 20th century was a century in which material civilization was greatly developed, but on the other hand, it was a century of mass weapons killed by the emergence of modern weapons, especially nuclear weapons, and the subsequent threat of human death due to nuclear proliferation. Despite knowing that the threat of nuclear proliferation will stop in the 21st century, terrorists are now trying to get nuclear weapons. The present invention relates to a nuclear shelter for protecting life against such threats.

  Japanese Patent Publication No. 2-42992   JP-A-8-112373   JP 11-336373 A   Japanese Patent No. 2919111   JP 2000-54666 A   Japanese Utility Model Publication No. 2-118571

The present invention is equipped with a neutron shielding function for protecting a life from a large amount of neutrons generated in a fission reaction in a low pressure chamber that can be used not only by a decompression training facility for specific athletes but also by general users on a daily basis. The nuclear shelter type low-pressure chamber.

The present invention is characterized in that the low-pressure chamber casing is made of a neutron shielding material and is a nuclear shelter type low-pressure chamber that shields neutrons generated by fission reaction.

The invention of claim 2 is a nuclear shelter type low pressure chamber in which the outer periphery of the low pressure chamber casing is covered with a neutron shielding material to shield neutrons generated by the fission reaction.

Conventionally, the low pressure chamber has been used only for the purpose of realizing a high altitude atmospheric pressure environment on a flat ground, but in the present invention, the low pressure chamber casing is manufactured with a neutron shielding material or the outer periphery of the low pressure chamber casing is covered with a neutron shielding material. Because it has a function to shield neutrons generated by fission reactions, when the low pressure chamber is used for the original purpose of use, the evacuation order is issued due to the outbreak of nuclear war and nuclear attack information By evacuating to the low pressure chamber, neutron exposure due to fission reaction can be avoided and precious life can be protected.

The best mode for carrying out the invention will be described. FIG. 1 is a sectional elevation view of a nuclear shelter type low-pressure chamber to which the present invention is applied, FIG. 2 is a left side view of the nuclear shelter-type low pressure chamber to which the present invention is applied, and FIG. 3 is a nuclear shelter type to which the present invention is applied. 4 is a right side view of the low pressure chamber, FIG. 4 is a plan view of the nuclear shelter type low pressure chamber to which the present invention is applied, FIG. 5 is a right elevation cross-sectional view of the nuclear shelter type low pressure chamber to which the present invention is applied, and FIG. The piping system diagram of the nuclear shelter type low pressure chamber to which the present invention is applied is shown respectively.

In the embodiment of the nuclear shelter type low pressure chamber of the present invention, the main structure is made up of a casing (2) having a strength capable of withstanding a low pressure and a neutron shielding material (3) covering the periphery of the casing (2). The end plates (4a) and (4b) with a neutron shielding material are tightly sealed to both ends of the casing (2). The end plates (4a) and (4b) with neutron shielding materials are provided with end plate openings (5a) and (5b), respectively, and the end plate openings (5a) and (5b) are equipped with neutron shielding materials. Airtight doors (6a) and (6b) are provided so as to be airtight and openable and closable, and the end plates with neutron shielding material (4a) and (4b) and the airtight doors with neutron shielding material (6a) and (6b) An airtight structure is formed by arranging a packing (not shown) around the airtight doors (6a) and (6b) with neutron shielding material and closely contacting the end plates (4a) and (4b) with neutron shielding material.

In addition, after the fission reaction, air pollution due to death ash fall or the like can be easily estimated, but the outside air intake ports (19) to (23) provided in the low pressure chamber (1) casing (2) have high performance. Since the activated carbon filter (30) and the HEPA filter (31) are connected, contaminants in the air can be completely filtered, and the resident in the low-pressure chamber can ensure safety from above the air.

In terms of industrial applicability, it is expected to be widely used not only for general households, but also for schools, gyms, hotels, hot springs, golf rest houses, hospitals, osteopaths, nursing homes, professional athletes, low-pressure room service shops, etc. The However, this is an extreme measure of life support, and we must make every effort to bring together a permanent peace where such devices do not need to function.
