本発明の第１の実施形態に係るタービン建屋における搬送物１０の搬送方法について、図１〜図５を用いて説明する。 Hereinafter, embodiments according to the present invention will be described with reference to the drawings.
(First Embodiment)
The method of transporting the transported object 10 in the turbine building according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 5.

［構成］
図１はタービン、発電機および復水器を含む機器の撤去前のタービン建屋の断面図である。
タービン建屋１は、例えば、オペレーティングフロア３、中間階４、地下階５等の複数のフロアが形成されている。 [Constitution]
FIG. 1 is a cross-sectional view of the turbine building before removal of equipment including a turbine, a generator and a condenser.
The turbine building 1 is formed with a plurality of floors such as an operating floor 3, an intermediate floor 4, and a basement floor 5, for example.

オペレーティングフロア３にはタービン及び発電機（以下、「タービン等」ともいう。）６を含む機器が基礎台７を介して設置されている。
タービン等６の下部には復水器９が中間階４を貫通して地下階５に設置されている。復水器９は基礎台７に支持されている。 On the operating floor 3, equipment including a turbine and a generator (hereinafter, also referred to as “turbine or the like”) 6 is installed via a base 7.
A condenser 9 penetrates the middle floor 4 and is installed in the basement floor 5 below the turbine and the like 6. The condenser 9 is supported by the base 7.

タービン建屋１の天井には例えば、縦ガータ２−１、及び縦ガータ２−１と垂直方向に２本の横ガータ２−２が設置され、縦ガータ２−１は２本の横ガータ２−２にガイドされて移動することができる。また、縦ガータ２−１には天井クレーン１１が設置され、縦ガータ２−１上を移動することができる。 For example, a vertical garter 2-1 and two horizontal garter 2-2 are installed on the ceiling of the turbine building 1 in the direction perpendicular to the vertical garter 2-1. You can move guided by 2. Further, an overhead crane 11 is installed on the vertical garter 2-1 and can move on the vertical garter 2-1.

図２はタービン等６および復水器９の撤去後（点線で示す。）のタービン建屋の断面図である。図３は基礎台７の平面図、図４はその斜視図である。
基礎台７は例えば、６対の脚部を有する櫓状の構造体であり、地下階５に設置されている。基礎台７の上面部はオペレーティングフロア３とほぼ同一面にあり、タービン等６を設置するとともに復水器９を接続するための開口部８−１が複数設けられている。基礎台７の形状や開口部８−１の数は、通常の沸騰水型原子力発電所では４個ないし５個形成されるが、タービンの大きさ、段数に応じて適宜変更可能である。 FIG. 2 is a cross-sectional view of the turbine building after the turbine and the like 6 and the condenser 9 have been removed (indicated by the dotted line). FIG. 3 is a plan view of the base 7 and FIG. 4 is a perspective view thereof.
The foundation base 7 is, for example, a turret-like structure having 6 pairs of legs, and is installed on the basement floor 5. The upper surface of the foundation base 7 is substantially on the same surface as the operating floor 3, and a plurality of openings 8-1 for installing the turbine and the like 6 and connecting the condenser 9 are provided. The shape of the foundation base 7 and the number of openings 8-1 are formed in 4 to 5 in a normal boiling water reactor, but can be appropriately changed according to the size of the turbine and the number of stages.

［作用］
次に、図２、図５を用いて放射性廃棄物の搬送作業について説明する。
図２に示すように、タービン等６及び復水器９を撤去した後には、基礎台７に形成された複数の開口部８−１及び復水器９の撤去後の空スペース８−２からなる空間８が表れる。 [Action]
Next, the operation of transporting radioactive waste will be described with reference to FIGS. 2 and 5.
As shown in FIG. 2, after removing the turbine and the like 6 and the condenser 9, the plurality of openings 8-1 formed in the base 7 and the empty space 8-2 after the removal of the condenser 9 Space 8 appears.

本実施形態では、基礎台７の垂直方向に延びる複数の空間８をタービン建屋内の廃棄物、資機材、人等の搬送物１０の搬送のための搬送経路として利用する。この複数の空間８により、複数の搬送経路を確保できるので、タービン建屋各階の各エリアへ最短距離で搬送及び移動が可能となる。 In the present embodiment, the plurality of spaces 8 extending in the vertical direction of the foundation base 7 are used as a transport path for transporting the transportable objects 10 such as waste, materials and equipment, and people in the turbine building. Since a plurality of transport paths can be secured by the plurality of spaces 8, it is possible to transport and move to each area on each floor of the turbine building in the shortest distance.

図５は、空間８における搬送手段として既設の天井クレーン１１を利用したもので、搬送設備を新設することなく、搬送物１０の搬送を行うことができる。
天井クレーン１１は、通常のタービン建屋では大小２台以上設置されているため、搬送対象物の大きさに応じて大小２台の天井クレーンを使い分けることができる。例えば、天井クレーン１１を用いて搬送物１０を、オペレーティングフロア３から空間８を通して中間階４及び地下階５に搬送する。天井クレーン１１の揚程が足りない場合は、長尺部材を介装する等の改造を行うことにより搬送することができる。 FIG. 5 uses an existing overhead crane 11 as a transport means in the space 8, and can transport the transported object 10 without newly installing a transport facility.
Since two or more overhead cranes 11 are installed in a normal turbine building, two large and small overhead cranes can be used according to the size of the object to be transported. For example, the overhead crane 11 is used to transport the transported object 10 from the operating floor 3 to the intermediate floor 4 and the basement floor 5 through the space 8. If the lift of the overhead crane 11 is insufficient, it can be transported by modifying it by interposing a long member or the like.

また、中間階４及び地下階５にフォークリフト１８等の建屋内を水平に移動する搬送設備を設置すれば、タービン建屋各階においても廃棄物、資機材等の搬送物１０の搬送を行うことができる。なお、図５において、基礎台７の脚部は省略している（図６，７，８，１０も同様である。）。 Further, if a transport facility such as a forklift 18 that moves horizontally in the building is installed on the intermediate floor 4 and the basement floor 5, the transport material 10 such as waste and materials and equipment can be transported on each floor of the turbine building. .. In FIG. 5, the legs of the foundation base 7 are omitted (the same applies to FIGS. 6, 7, 8 and 10).

［効果］
以上説明したように、本実施形態によれば、タービン等６及び復水器９を撤去した後に表れる複数の空間８をタービン建屋内の搬送物１０の搬送及び移動経路に利用できるとともに、複数の空間８により複数の経路を確保できるので、タービン建屋各階の各エリアへ最短距離で搬送及び移動が可能となる。
また、空間８の搬送手段として、既設の天井クレーン１１を利用でき、搬送設備を新設することなく、タービン建屋各階間の搬送物１０の搬送を行うことができる。 [effect]
As described above, according to the present embodiment, the plurality of spaces 8 appearing after the turbine and the like 6 and the condenser 9 are removed can be used for the transport and movement paths of the transported objects 10 in the turbine building, and a plurality of spaces 8 can be used. Since a plurality of routes can be secured by the space 8, it is possible to transport and move to each area on each floor of the turbine building in the shortest distance.
Further, the existing overhead crane 11 can be used as the transporting means of the space 8, and the transported object 10 can be transported between the floors of the turbine building without newly installing the transport equipment.

（第２の実施形態）
本発明の第２の実施形態に係るタービン建屋における搬送物１０の搬送方法について、図６〜８を用いて説明する。 (Second embodiment)
The method of transporting the transported object 10 in the turbine building according to the second embodiment of the present invention will be described with reference to FIGS. 6 to 8.

通常の搬送では既設の天井クレーン１１を使用するが、天井クレーン１１のみでは効率的に搬送できない場合、あるいは作業員を移動させる場合等があり、その場合は搬送設備を新設する。 In normal transportation, the existing overhead crane 11 is used, but there are cases where efficient transportation cannot be achieved with the overhead crane 11 alone, or there are cases where workers are moved. In that case, a new transportation facility is installed.

本実施形態は、基礎台７の上面および空間８を利用して搬送設備を新設するものである。その他の構成は第１の実施形態と同様である。
新設する搬送設備としては資機材、廃棄物用のクレーン１２（図６）、作業員、資機材等用のエレベータ１３（図７）、クレーン１２及びエレベータ１３の併用（図８）が例示される。 In this embodiment, a transport facility is newly installed using the upper surface of the base 7 and the space 8. Other configurations are the same as in the first embodiment.
Examples of the newly installed transport equipment include equipment and materials, a crane 12 for waste (Fig. 6), an elevator 13 for workers and equipment and materials (Fig. 7), and a combined use of a crane 12 and an elevator 13 (Fig. 8). ..

クレーン１２については例えば、断面門型の脚部が開口部８−１を跨ぐように基礎台７の上面に据え付け、固定して設置される。エレベータ１３については例えば、下端を地下階５に固定したガイドレール１４を基礎台７に支持固定し、エレベータ１３のゲージが開口部８−１を通過するように設置する。 The crane 12 is installed, for example, installed on the upper surface of the foundation base 7 so that the cross-sectional gate-shaped legs straddle the opening 8-1 and are fixedly installed. Regarding the elevator 13, for example, a guide rail 14 whose lower end is fixed to the basement floor 5 is supported and fixed to the foundation base 7, and the gauge of the elevator 13 is installed so as to pass through the opening 8-1.

本実施形態によれば、新設するクレーン１２については、開口部８−１を跨いで基礎台７上に設置され、またエレベータ１３については開口部８−１に基礎台７を介して設置されるので、いずれの搬送設備についても空間８をタービン建屋内の搬送物１０の搬送経路として利用することができる。また、エレベータ１３のガイドレール１４などを設置するための基礎工事を最小限に抑えることができる。 According to the present embodiment, the newly installed crane 12 is installed on the base 7 across the opening 8-1, and the elevator 13 is installed in the opening 8-1 via the base 7. Therefore, in any of the transport facilities, the space 8 can be used as a transport path for the transport object 10 in the turbine building. In addition, the foundation work for installing the guide rail 14 and the like of the elevator 13 can be minimized.

（第３の実施形態）
本発明の第３の実施形態に係るタービン建屋における搬送物１０の搬送方法について、図９〜１０を用いて説明する。
本実施形態は、各フロア及び空間８を用いて、搬送物１０の搬入処理から保管処理に至るまでの各工程を示したものである。 (Third Embodiment)
A method of transporting the transported object 10 in the turbine building according to the third embodiment of the present invention will be described with reference to FIGS. 9 to 10.
In this embodiment, each floor and space 8 are used to show each process from the carry-in process to the storage process of the transported object 10.

図９は、原子炉建屋内等の解体現場において発生する廃棄物等を搬送処理する工程ａ〜工程ｄからなる搬送処理工程の一例である。
廃棄物は、解体現場にて切断・収納された後、タービン建屋に移送される。その後、除染や固化などの廃棄物の処理、放射能濃度の測定など廃棄物の検査を経てタービン建屋内に一時保管される。 FIG. 9 is an example of a transport processing step including steps a to d for transporting waste and the like generated at a dismantling site such as inside a nuclear reactor building.
The waste is cut and stored at the dismantling site and then transferred to the turbine building. After that, it is temporarily stored in the turbine building after being treated for waste such as decontamination and solidification, and inspected for waste such as measurement of radioactivity concentration.

なお、廃棄物を検査する廃棄物検査設備１７、処理する廃棄物処理設備１６、保管する機材等は工程ａの前に、既設天井クレーン１１等により前記空間８を経由してそれぞれ検査、処理、保管の各フロアに搬入される。 The waste inspection facility 17 for inspecting waste, the waste treatment facility 16 for processing, the equipment for storage, etc. are inspected and treated by the existing overhead crane 11 or the like via the space 8 before the step a. It is carried to each floor of storage.

以下、工程ａ〜工程ｄからなる搬送処理工程に基づいて廃棄物等の搬送物１０を搬送する搬送作業を、図１０を参照して説明する。
先ず、工程ａにおいて原子炉建屋で解体、切断、収納された廃棄物等の搬送物１０がタービン建屋（Ｔ／Ｂ）の搬入口１５からオペレーティングフロア３に搬入される。 Hereinafter, the transport operation for transporting the transported material 10 such as waste based on the transport processing step including the steps a to d will be described with reference to FIG.
First, in step a, the transported material 10 such as waste dismantled, cut, and stored in the reactor building is carried into the operating floor 3 from the carry-in entrance 15 of the turbine building (T / B).

その後、工程ｂにおいて、基礎台７上面を利用して新設されたクレーン１２により中間階４へ搬送物１０が空間８を用いて垂直搬送され、中間階４に設置した廃棄物処理設備１６により処理が行なわれる。 After that, in step b, the transported object 10 is vertically transported to the intermediate floor 4 by the newly installed crane 12 using the upper surface of the foundation base 7 using the space 8, and is treated by the waste treatment facility 16 installed in the intermediate floor 4. Is done.

その後、工程ｃにおいて、同じく基礎台７上面を利用して新設されたエレベータ１３により、処理後の搬送物１０は地下階５に空間８を用いて垂直搬送され、地下階５に設置した廃棄物検査設備１７により放射能濃度などの測定を行う。 After that, in step c, the processed material 10 is vertically transported to the basement floor 5 using the space 8 by the elevator 13 newly installed using the upper surface of the foundation base 7, and the waste installed in the basement floor 5 is used. The inspection equipment 17 measures the radioactivity concentration and the like.

最後に、工程ｄにおいて、放射能濃度の測定された搬送物１０は地下階５に設置した保管エリアに水平搬送され保管される。
なお、搬送物１０を垂直搬送する場合、既設の天井クレーン１１の併用も可能であり、搬送物１０の水平搬送をする場合は、コンベアやフォークリフト１８等を用いる。また、工程ａでは搬送物１０をオペレーティングフロア３に搬入したが、搬入フロアはその他のフロアでもよい。 Finally, in step d, the transported object 10 whose radioactivity concentration has been measured is horizontally transported and stored in the storage area installed in the basement floor 5.
When the transported object 10 is vertically transported, the existing overhead crane 11 can be used in combination, and when the transported object 10 is horizontally transported, a conveyor, a forklift 18, or the like is used. Further, in the step a, the transported object 10 is carried into the operating floor 3, but the carry-in floor may be another floor.

以上、本実施形態によれば、各階を廃棄物処理エリア、廃棄物検査エリア、廃棄物保管エリアなどのエリアに利用する際、空間８を搬送物１０の搬入、搬出のための経路の一つとして利用できる。 As described above, according to the present embodiment, when each floor is used as an area such as a waste treatment area, a waste inspection area, and a waste storage area, the space 8 is one of the routes for carrying in and out of the transported material 10. Can be used as.

また、復水器９など大型の機器が設置されている地下階５は耐床荷重が大きく、かつ十分な保管容量が確保できるので、保管エリアとして利用できる。また、廃棄物処理設備１６を中間階４に、廃棄物検査設備１７を地下階５に設置することにより、搬送物１０の搬送経路が錯綜することなく、廃棄物の搬送処理工程を確実かつ効率的に実行することができる。 Further, the basement floor 5 in which a large device such as a condenser 9 is installed has a large floor load and can secure a sufficient storage capacity, so that it can be used as a storage area. Further, by installing the waste treatment equipment 16 on the intermediate floor 4 and the waste inspection equipment 17 on the basement floor 5, the transportation route of the transported material 10 is not complicated, and the waste transportation processing process is surely and efficiently performed. Can be executed as a target.

さらに、空間８は複数あるため、廃止措置の各段階において、必要なエリアの用途、スペースが変更になった場合でも、各エリアへの効率的な搬送経路を容易に確保することができる。 Further, since there are a plurality of spaces 8, it is possible to easily secure an efficient transportation route to each area even if the required area usage and space are changed at each stage of decommissioning.

以上、本発明のいくつかの実施形態、変形例を説明したが、これらの実施形態等は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態等は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態等は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 Although some embodiments and modifications of the present invention have been described above, these embodiments and the like are presented as examples and are not intended to limit the scope of the invention.
