Description

本発明は、原子力発電所の構内施設の配置方法に係り、特に、予期せぬ災害や人為的な行為により陸上の施設が損傷を受けた場合であっても、原子力発電所全体の安全性が維持される原子力発電所の構内配置に関する。   The present invention relates to a method for arranging a facility of a nuclear power plant, and in particular, even when a land facility is damaged due to an unexpected disaster or a human act, the safety of the entire nuclear power plant is improved. Regarding on-site arrangement of nuclear power plants to be maintained.

原子力発電所では、何重もの安全対策を講じ、万一事故が発生した場合でも周辺環境に影響を及ぼさないように安全管理がなされている。事故発生時は、原子炉を安全に停止し、核燃料を冷却し、放射性物質を閉じ込める様々な安全機能が働く。   At nuclear power plants, many safety measures are taken, and safety management is carried out so that even if an accident occurs, the surrounding environment is not affected. In the event of an accident, various safety functions work to shut down the reactor safely, cool the nuclear fuel, and confine radioactive materials.

一般に上記のような安全機能を備えた施設（建屋）の構内配置において、航空機などの外部飛来物が衝突する脅威に対し、原子炉を停止可能な安全機能が防護される必要である。そのため、外部飛来物の落下を確率的に考慮する必要のないサイト（敷地，用地）を選定することでこれまでは対応していた。   In general, in a premises arrangement of a facility (building) having a safety function as described above, it is necessary to protect a safety function capable of shutting down a nuclear reactor against a threat of collision of an external flying object such as an aircraft. For this reason, it has been possible so far to select sites (sites, sites) that do not need to consider the fall of external flying objects in a probabilistic manner.

しかしながら、2001年9月11日のアメリカ同時多発テロ事件以降、テロ対策の社会的な要求が高まったことから、国内の新設の原子力発電所において、航空機などの外部飛来物の衝突に対して原子炉建屋内の安全機能を維持するための設備が破損した場合でも原子炉建屋の炉心及び使用済燃料を冷却維持するため、特定重大事故等対処施設（以下、特重建屋）の設置が求められている。   However, since the September 11, 2001 terrorist attacks in the United States, social demands for anti-terrorism have increased. At a newly established nuclear power plant in Japan, atomic attacks against external projectiles such as aircraft have occurred. Even if facilities for maintaining the safety functions inside the reactor building are damaged, it is required to install facilities for handling specific serious accidents (hereinafter referred to as special heavy buildings) in order to keep the reactor building core and spent fuel cooled. ing.

特重建屋は、原子炉建屋内の安全機能維持のバックアップであるため、航空機などの外部飛来物が原子炉建屋と同時に衝突、または外部飛来物侵入経路上にあることで連続的に衝突し、破損するのを防ぐことが求められている。   The special heavyweight building is a backup for maintaining the safety functions in the reactor building, so that external projectiles such as aircraft collide with the reactor building at the same time, or because they are on the external projectile intrusion route, There is a need to prevent breakage.

一般的に、建屋の外壁の厚さを外部飛来物が貫通しない頑健な鉄筋コンクリート構造にすることで、建屋内に設置されている安全機能の系統や機器を外部飛来物の衝突から防護することが可能である。   In general, the thickness of the outer wall of the building is made of a robust reinforced concrete structure that does not allow external flying objects to penetrate, so that the safety function systems and equipment installed in the building can be protected from collision with external flying objects. Is possible.

本技術分野の背景技術として、特許文献１のような技術がある。特許文献１には、原子炉建屋を地下６０ｍ〜地下１００ｍに建設する地下埋没型原子力発電所が開示されている。   As a background art in this technical field, there is a technique as described in Patent Document 1. Patent Document 1 discloses an underground nuclear power plant in which a nuclear reactor building is constructed 60m to 100m underground.

また、特許文献２には、予期せぬ事故が発生した場合に中性子線対策として水没させる原子力発電所が開示されている。   Further, Patent Document 2 discloses a nuclear power plant that is submerged as a neutron countermeasure when an unexpected accident occurs.

また、特許文献３には、津波により陸上の電源設備を喪失した場合でも、港湾または沖合いに設置した外部電源および淡水受容れ設備を介して船舶から電気と淡水を供給可能な原子力発電所が開示されている。   Further, Patent Document 3 discloses a nuclear power plant that can supply electricity and fresh water from a ship via an external power supply and fresh water receiving equipment installed in a harbor or offshore even when the onshore power supply facility is lost due to a tsunami. Has been.

しかしながら、頑健なコンクリートの外壁でも、外部飛来物が衝突することで発生する振動影響や燃料搭載物であった場合に発生する火災の建屋への侵入による安全機能設備の損傷を防ぐことはできない。すなわち、原子炉建屋と特重建屋に外部飛来物が同時に、または連続的に衝突する場合、物理的な衝撃や振動及び火災により安全機能設備が損傷する可能性が生じる。   However, even with a strong concrete outer wall, it is not possible to prevent damage to the safety function equipment due to the vibration effect caused by the collision of an external projectile or the intrusion of a fire in the case of a fuel loaded object. That is, when an external projectile collides with the reactor building and the special-weight building at the same time or continuously, there is a possibility that the safety functional equipment is damaged by physical shock, vibration, and fire.

上記特許文献１の地下埋没型原子力発電所は、水素爆発に対する耐性や放射能漏れ防止の観点で有効な手段であると考えられるが、膨大な建設費用を必要とし、また、地下に様々な建屋や構造物を建設する必要があるため発電所の規模が限定的となり、実用化は困難である。   The underground buried nuclear power plant described in Patent Document 1 is considered to be an effective means from the viewpoint of resistance to hydrogen explosion and prevention of radioactivity leakage, but it requires enormous construction costs and various underground buildings. Because it is necessary to construct a building and a structure, the scale of the power plant is limited and practical application is difficult.

また、特許文献２は原子力発電所の具体的な水没方法が開示されておらず、やはり実用化は困難である。   Further, Patent Document 2 does not disclose a specific submergence method for a nuclear power plant, and it is difficult to put it to practical use.

また、特許文献３の原子力発電所は、外部からの電源および淡水供給の継続が可能であるが、安全機能を備えた主要な施設（建屋）は陸上に設置されており、上述したような非常時の安全機能の維持は困難である。   In addition, the nuclear power plant of Patent Document 3 can continue to supply power and fresh water from the outside, but the main facilities (buildings) with safety functions are installed on land, Maintaining safety functions at times is difficult.

そこで、本発明は、津波等の予期せぬ自然災害時や航空機等の外部飛来物が原子力発電所構内に侵入し建屋に衝突する場合であっても、特重建屋内の安全機能設備の健全性を維持することが可能な原子力発電所の構内配置を提供することを目的とする。   Therefore, the present invention provides for the soundness of the safety function equipment in the heavy duty building even in the event of an unexpected natural disaster such as a tsunami or when an external projectile such as an aircraft enters the premises of a nuclear power plant and collides with the building. The purpose is to provide an on-site arrangement of nuclear power plants capable of maintaining

上記課題を解決するために、本発明は、核燃料を用いて発電運転する原子力プラントであって、前記原子力プラントは、内部に原子炉が設置された原子炉建屋と、内部に前記原子炉の安全機能を維持する設備が設置された特重建屋と、前記原子炉建屋と前記特重建屋とを連結する連絡トレンチと、を有し、前記特重建屋は、水中に設置されることを特徴とする。   In order to solve the above-described problems, the present invention provides a nuclear power plant that generates power using nuclear fuel. The nuclear power plant includes a reactor building in which a nuclear reactor is installed, and a safety of the nuclear reactor in the reactor. A special-weight building in which facilities for maintaining functions are installed, and a communication trench connecting the reactor building and the special-weight building, wherein the special-weight building is installed in water. To do.

また、本発明は、核燃料を用いて発電運転する原子力プラントの構内施設配置方法であって、内部に原子炉が設置された原子炉建屋を陸上に配置し、内部に前記原子炉の安全機能を維持する設備が設置された特重建屋を水中に配置し、前記原子炉建屋と前記特重建屋を連絡トレンチで連結することを特徴とする。   The present invention also relates to a method for arranging a facility in a nuclear power plant that performs power generation operation using nuclear fuel, wherein a nuclear reactor building having a nuclear reactor inside is arranged on land, and the safety function of the nuclear reactor is provided inside. A special-weight building in which equipment to be maintained is installed in water, and the reactor building and the special-weight building are connected by a connecting trench.

本発明によれば、特重建屋が従来の他建屋と同等の躯体構造であっても、津波による被災や航空機等の外部飛来物の衝突から回避することができ、原子力発電所の安全機能設備の健全性を確保できる。   According to the present invention, even if the special heavy building has the same structure as that of other conventional buildings, it can be avoided from damage caused by tsunami and collision of external flying objects such as aircraft, and the safety functional equipment of the nuclear power plant Can be ensured.

上記した以外の課題、構成及び効果は、以下の実施形態の説明により明らかにされる。   Problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.

本発明の一実施形態に係る原子力発電所の構内配置を示す平面図である。It is a top view which shows campus arrangement | positioning of the nuclear power plant which concerns on one Embodiment of this invention. 図1に示す原子力発電所のＡ−Ａ’部断面図である。FIG. 2 is a cross-sectional view taken along the line A-A ′ of the nuclear power plant shown in FIG. 従来の代表的な原子力発電所の構内配置を示す平面図である。It is a top view which shows the campus arrangement | positioning of the conventional typical nuclear power plant.

以下、図面を用いて本発明の実施例を説明する。なお、各図面において同一の構成については同一の符号を付し、重複する部分についてはその詳細な説明を省略する。   Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals, and detailed description of overlapping portions is omitted.

先ず比較のため、図３を用いて従来の原子力発電所の構内配置について説明する。図３は従来の代表的な原子力発電所の構内配置を示す平面図である。   First, for comparison, the on-site arrangement of a conventional nuclear power plant will be described with reference to FIG. FIG. 3 is a plan view showing the layout of a typical typical nuclear power plant.

原子力発電所は、火力発電所と同様に、発電に利用した蒸気の冷却に大量の水を必要とするため、多くは海岸沿い、または河川や湖のそばに建設される。図３の符号１０は海や河川、湖などの冷却水源を示している。   Nuclear power plants, like thermal power plants, require a large amount of water to cool the steam used for power generation, so many are built along the coast or near rivers and lakes. The code | symbol 10 of FIG. 3 has shown the cooling water sources, such as the sea, a river, and a lake.

一般的な原子力発電所の構内には、内部に原子炉が設置された原子炉建屋２、原子炉で発生した蒸気により回転して発電する蒸気タービン及び発電機が設置されたタービン建屋１３、主に原子炉の安全機能を維持するための設備が設置された特重建屋９、原子力発電所を維持管理するためのその他の建屋や構造物４〜６などが配置されている。なお、発電機は蒸気タービンとは別の建屋、例えば、他建屋／構造物６に設置する場合もある。   A general nuclear power plant premises includes a reactor building 2 in which a nuclear reactor is installed, a steam turbine that rotates by steam generated in the nuclear reactor, and a turbine building 13 in which a generator is installed. A special-weight building 9 in which facilities for maintaining the safety function of the nuclear reactor are installed, and other buildings and structures 4 to 6 for maintaining and managing the nuclear power plant are arranged. The generator may be installed in a building different from the steam turbine, for example, in another building / structure 6.

原子炉建屋２内の原子炉では、核燃料（主にウラン）を核分裂させて熱エネルギーを得て、水を沸かして蒸気を発生させる。   In the nuclear reactor in the reactor building 2, nuclear fuel (mainly uranium) is fissioned to obtain thermal energy, and water is boiled to generate steam.

原子炉建屋２と特重建屋９の間には、連絡通路となる連絡トレンチ１１が設けられている。特重建屋９には、給排気を行うための特重建屋給排気筒７が設けられている。   A communication trench 11 serving as a communication passage is provided between the reactor building 2 and the special-weight building 9. The special heavy building 9 is provided with a special heavy building air supply / exhaust cylinder 7 for supplying and exhausting air.

上述したように、特重建屋９は、原子炉建屋内の安全機能維持のバックアップであるため、航空機などの外部飛来物が原子炉建屋と同時に衝突、または外部飛来物侵入経路上にあることで連続的に衝突し、破損するのを防ぐことが求められている。   As described above, since the special heavy building 9 is a backup for maintaining the safety function in the reactor building, an external projectile such as an aircraft collides with the reactor building at the same time or is on an external projectile intrusion route. There is a need to prevent continuous collisions and damage.

そこで、従来の原子力発電所では、図３のように、特重建屋９と原子炉建屋２を、十分な離隔距離（例えば約１００ｍ）を設けて配置している。また、平面的に見て、特重建屋９と原子炉建屋２を同一直線上に配置した場合、特重建屋９と原子炉建屋２のいずれか一方に外部飛来物が衝突した場合、連続してもう一方の建屋に衝突する可能性が高いため、図３のように、特重建屋９と原子炉建屋２をずらした位置に配置している。そのため、より広い敷地が必要となり、構内施設配置の配置効率が低下する。   Therefore, in the conventional nuclear power plant, as shown in FIG. 3, the special-weight building 9 and the reactor building 2 are arranged with a sufficient separation distance (for example, about 100 m). In addition, in a plan view, when the special heavy building 9 and the reactor building 2 are arranged on the same straight line, when an external projectile collides with either the special heavy building 9 or the nuclear reactor building 2, the Since the possibility of collision with the other building is high, the special-weight building 9 and the reactor building 2 are arranged at a shifted position as shown in FIG. Therefore, a larger site is required, and the arrangement efficiency of the on-site facility arrangement is reduced.

図１および図２を用いて、本実施例の原子力発電所の構内配置を説明する。図１は本発明の構内施設配置方法による原子力発電所の平面図である。また、図２は図１のＡ−Ａ’部断面を概念的に示している。   The on-site arrangement of the nuclear power plant according to this embodiment will be described with reference to FIGS. FIG. 1 is a plan view of a nuclear power plant according to the on-site facility arrangement method of the present invention. FIG. 2 conceptually shows a cross section taken along line A-A ′ of FIG. 1.

本実施例の原子力発電所（原子力プラント）１では、特重建屋９が冷却水源１０となる水中、すなわち海中、または河川や湖の水中に設置されている。また、原子炉建屋２は特重建屋９の近傍となるよう冷却水源１０側の陸上に設置している。   In the nuclear power plant (nuclear power plant) 1 of the present embodiment, the special heavy building 9 is installed in the water that serves as the cooling water source 10, that is, in the sea or in the water of a river or a lake. Further, the reactor building 2 is installed on land on the cooling water source 10 side so as to be in the vicinity of the special weight building 9.

水中に設置される特重建屋９には、原子力発電所１の中央制御室の代替設備（バックアップ設備）の他、溶融炉心の冷却や使用済み燃料ピット（SFP：Spent Fuel Pit）及び格納容器への冷却水のスプレイを実施する代替注水設備、制御監視計器などが収容されており、原子炉建屋２内の同等の機能を有する設備に航空機などの外部飛来物が衝突したり、津波により損傷が生じた場合であっても、原子炉の炉心及び使用済み燃料の冷却維持が可能である。   In the special heavy building 9 installed in the water, in addition to the alternative equipment (backup equipment) of the central control room of the nuclear power plant 1, cooling of the molten core, spent fuel pit (SFP) and containment vessel Alternative water injection equipment, control monitoring instruments, etc. for spraying cooling water are housed, and external flying objects such as aircraft collide with equipment with equivalent functions in the reactor building 2 or damage caused by tsunami Even if it occurs, it is possible to keep the reactor core and spent fuel cool.

また、仮に、原子炉建屋２と特重建屋９が航空機などの衝突経路上（同一直線上）に設置され、連続衝突が考えられる場合であっても、特重建屋９を水中に設置することで海水や河川・湖の水により衝撃が緩和され、特重建屋９の健全性を保つことができる。   Moreover, even if the reactor building 2 and the special heavy building 9 are installed on a collision path (on the same straight line) of an aircraft or the like and a continuous collision is considered, the special heavy building 9 should be installed in the water. Therefore, the impact is alleviated by seawater and river / lake water, and the soundness of the special heavy building 9 can be maintained.

また、図１において特重建屋９用の換気空調給排気筒は地上露出構造物となり、原子炉建屋２と同時衝突または連続的衝突の可能性が生じる。このため、特重建屋給排気筒７，８のように複数設けて多重性を持たせることで、一方が衝突により機能を喪失した場合であっても、もう一方の機能は損失しないよう他建屋または構造物（他建屋／構造物３〜６）が障壁となる位置に換気空調給排気筒を設置する。   In FIG. 1, the ventilation / air conditioning supply / exhaust cylinder for the heavy duty building 9 becomes an exposed structure on the ground, and there is a possibility of simultaneous collision or continuous collision with the reactor building 2. For this reason, as in the case of the special-weight building supply / exhaust cylinders 7 and 8, by providing a plurality and providing multiplicity, even if one of the functions is lost due to a collision, the other function is not lost. Or a ventilation air-conditioning supply / exhaust pipe is installed in the position where a structure (other buildings / structures 3-6) becomes a barrier.

なお、航空機等の衝突により屋外で火災が発生した場合でも、換気空調給排気筒を多重化し、他建屋または構造物を衝突からの障壁とすることで、影響を受けない。これにより、特重建屋９の換気空調機能が維持される。   In addition, even when a fire occurs outdoors due to a collision with an aircraft or the like, it is not affected by multiplexing the ventilation air-conditioning supply / exhaust cylinders and using other buildings or structures as a barrier from the collision. Thereby, the ventilation air-conditioning function of the special heavy building 9 is maintained.

特重建屋内９内の安全機能設備は、原子炉の炉心及び燃料プール冷却を維持するもので、連絡トレンチ１１によって原子炉建屋２に連絡物を接続する。この連絡トレンチ１１は地下埋設とし、１．５ｍ以上の厚さの鉄筋コンクリート製の壁により建設された構造であり、仮に航空機が衝突した場合であっても衝撃に耐え得る構造としている。これにより、原子炉の炉心及び使用済み燃料の冷却が維持される。   The safety function facility in the heavy duty building 9 maintains the reactor core and fuel pool cooling, and connects the communication objects to the reactor building 2 by the communication trench 11. The connection trench 11 is buried underground and is constructed of a reinforced concrete wall having a thickness of 1.5 m or more, and is constructed to withstand an impact even if an aircraft collides. This maintains the cooling of the reactor core and spent fuel.

また、原子炉建屋２は、特重建屋９を設置した冷却水源１０側に設置することで、原子炉建屋２及び特重建屋９を連絡する計画物及び連絡トレンチ１１の建設時のコンクリート量を低減することができる。   In addition, the reactor building 2 is installed on the cooling water source 10 side where the special heavy building 9 is installed, so that the planned amount for connecting the nuclear reactor building 2 and the special heavy building 9 and the concrete amount at the time of construction of the communication trench 11 can be reduced. Can be reduced.

なお、上述したように、図１および図２に示す原子力発電所の構内配置では、特重建屋９を水中に建設し、原子炉建屋２を特重建屋９に近接した陸上に建設することで、原子炉建屋２と特重建屋９の同時損傷を防止することができる。そのため、それら以外の建屋、他建屋／構造物３〜６は自由な配置（レイアウト）が可能である。例えば、他建屋／構造物３内に蒸気タービンや発電機を設置したり、他建屋／構造物４内に原子力発電所１の中央制御室を設けてもよい。   As described above, in the on-site arrangement of the nuclear power plant shown in FIGS. 1 and 2, the special heavy building 9 is constructed underwater, and the reactor building 2 is constructed on land close to the special heavy building 9. Simultaneous damage of the reactor building 2 and the special heavy building 9 can be prevented. Therefore, other buildings and other buildings / structures 3 to 6 can be freely arranged (layout). For example, a steam turbine or a generator may be installed in the other building / structure 3, or a central control room of the nuclear power plant 1 may be provided in the other building / structure 4.

以上説明したように、本実施例の原子力発電所の構内配置によれば、従来のように原子炉建屋と特重建屋間に十分な離隔距離を取る必要がなく、原子力発電所の構内配置のスペース効率を向上することができる。   As described above, according to the on-site arrangement of the nuclear power plant of the present embodiment, there is no need to provide a sufficient separation distance between the reactor building and the special-weight building as in the past, and the on-site arrangement of the nuclear power plant is not necessary. Space efficiency can be improved.

また、特重建屋９を水中に建設することで、津波等の予期せぬ自然災害時や航空機等の外部飛来物が原子力発電所構内に侵入し建屋に衝突する場合であっても、特重建屋内の安全機能設備の健全性を維持することが可能となり、原子力発電所の安全性が向上する。   In addition, by constructing the special heavy building 9 underwater, even in the event of an unexpected natural disaster such as a tsunami or when an external flying object such as an aircraft enters the nuclear power plant and collides with the building, the special heavy building 9 It is possible to maintain the soundness of indoor safety function facilities and improve the safety of nuclear power plants.
