Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that conventional nuclear power generation has the difficulty of the impracticability of mass production because bodies of reactors, components such as piping, devices and the like are not standardized and that the maintenance of facilities, manual repair and dismantling labor and the like which are dangerous even if workers wear radioactivity protective clothing involve man-hours, risks and huge budgets because it is necessary to handle each reactor individually. <P>SOLUTION: A standardized small-sized nuclear reactor (1) includes components such as piping, devices (2), secondary cooling water pipe joints (3) and the like which are standardized. The reactor (1) is inspected and repaired by an inspection robot (4) and is dismantled by a dismantling robot (5) because the reactor (1) is standardized to eliminate the manual labor which is dangerous even if workers wear radioactive protective clothing. As the reactor (1) is surrounded by a standardized enclosure (6) and is provided with standardized hooks (7) for a crane for the purpose of transportation and replacement, the reactor (1) can be assembled on lines, can be used not only in a fixed site but also as a movable body and can be replaced easily. The external encapsulation of a secondary cooling system (10) and a turbine (11) into a small-sized enclosure (12) enhances the degree of freedom in combinations. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

この発明は、比較的小発電力量の、規格の統一された大量生産可能な原子炉を、例えば加圧水型等の手馴れた原子炉で提供することにより、配管などの部品、装置類、二次冷却水管接続部やマンマシンインタフェースを規格化することを可能にし、建設時の大幅なコストダウンと、修理等を含む維持管理の容易化、さらにロボットを使用しての点検の平易化、同じくロボットを使用しての解体作業の容易化を提供し、それら費用の節減を提供するものである。
また、囲む筐体を比較的小型にし、規格化しておくことにより、固定された立地のみならず、移動体すなわち、艦船や潜水艦等でも使用可能にしており、さらにまた、二次冷却と、タービンを外付けで比較的小型の筐体に封入することにより、組み合わせの自由度を増加させた規格化された原子炉に関するものである。The present invention provides a reactor capable of mass production with a relatively small amount of generated electric power and a standardized standard, such as a pressurized water type reactor. It is possible to standardize cooling water pipe connections and man-machine interfaces, greatly reduce costs during construction, facilitate maintenance and maintenance including repairs, and simplify inspections using robots. It provides ease of dismantling work using and provides cost savings.
In addition, by enclosing the enclosure relatively small and standardizing it, it can be used not only for fixed locations but also for moving objects, such as ships and submarines. The present invention relates to a standardized nuclear reactor in which the degree of freedom of combination is increased by encapsulating in a relatively small casing.

従来、加圧水型原子炉や沸騰水型原子炉などに代表される原子力発電においては、用地買収の困難や、総発電力量や計画がプラントによって異なるなどの理由から、プラントや原子炉本体、配管などの部品、装置類に至るまで、大量生産できないといった困難、開発時期の相違や、設計思想の変更により、同じく原子炉本体や部品、装置類が画一化されないという困難があった。
また、経年変化で劣化した原子炉や、老朽化した施設全体を維持管理することや、放射能防護しながらの人手による危険な修理・解体作業なども、原子炉ごとの個別の対応で工数と危険と莫大な予算を必要とした。また、十分な半減期を経て、土地が安全となるまでに用地を無駄に遊ばせておく必要もあった。これらは放射性廃棄物ともども、維持管理費となって累積され、さらに顧客の電気代を圧迫し、将来に禍根を残す恐れがあった。
これらは、プルサーマル計画等燃料を変更しても同様の困難が生じる。Conventionally, in nuclear power generation represented by pressurized water reactors and boiling water reactors, plants, reactor bodies, pipes, etc. due to difficulties in land acquisition and total power generation and plans differ from plant to plant. There was a difficulty that mass production could not be performed until the parts and devices of the above, and the reactor body, components, and devices were not uniformized due to differences in development time and changes in design philosophy.
In addition, maintenance and management of the reactors that have deteriorated due to secular change, the entire aging facility, and dangerous repairs and dismantling work by hand while protecting the radioactivity can be handled individually by each reactor. It needed danger and a huge budget. In addition, after a sufficient half-life, it was necessary to let the land play in vain before the land became safe. Both of these wastes and radioactive wastes were accumulated as maintenance costs, further pressing the customer's electricity bills and possibly leaving a root in the future.
Even if these change fuels, such as a pull thermal plan, the same difficulty arises.
