Description
本発明は、制御棒挿入性耐震試験装置に関する。
The present invention relates to a control rod insertion property seismic test apparatus.
原子力発電所は、運転によって放射性物質が生じることから、周囲環境へ影響を及ぼさないように、各種の安全対策が講じられている施設である。日本では、原子炉建屋に地震感知器が設置されており、原子炉は設定値を上回る大きな揺れを感知すると制御棒を炉心に挿入して自動停止するように設計されている。 A nuclear power plant is a facility where various safety measures are taken so as not to affect the surrounding environment because radioactive materials are generated during operation. In Japan, seismic detectors are installed in the reactor building, and the reactor is designed to automatically shut down by inserting a control rod into the core when a large shake exceeding the set value is detected.
日本電気協会が発行した「原子力発電所耐震設計技術規程JEAC4601-2008」においては、「制御棒は、基準地震動Ssが起きている状態であっても緊急に挿入されなければならない」および「BWRにおいてはシースが、PWRにおいては制御棒被覆管が、中性子吸収材を保持する機能を喪失していない」と記載されており、制御棒に求められる機能として、地震時の挿入機能と中性子吸収材を保持する機能が挙げられている。さらに、これらの機能については、試験あるいは解析によって、許容基準の適合性を確認しなければならないことが規定されている。 According to the “JEAC4601-2008 Nuclear Power Station Seismic Design Technical Regulations” issued by the NEC Association, “Control rods must be urgently inserted even when the standard seismic motion Ss is occurring” and “BWR `` The sheath does not lose the function to hold the neutron absorber in the PWR in the PWR '', and the functions required for the control rod include the insertion function during earthquakes and the neutron absorber. The function to hold is mentioned. Furthermore, for these functions, it is stipulated that the conformity of acceptance criteria must be confirmed by testing or analysis.
沸騰水型原子炉の場合、制御棒は炉心の下側より挿入される。制御棒は、非挿入時には炉心支持板の下方に配置される制御棒案内管に収められ、その下端はカップリングを介して制御棒駆動機構の駆動ピストンに接続されている。制御棒駆動機構にはスクラム配管を介して水圧制御ユニットが接続され、駆動ピストンは、自動停止時には水圧によって駆動される。自動停止信号が発信されると、水圧制御ユニットのスクラム弁が開き、窒素容器に蓄えられていた窒素ガスの圧力がアキュムレータにて水圧に変換され、この水動力はスクラム配管を伝わって制御棒駆動機構に供給される。制御棒駆動機構の駆動ピストンは供給された水圧によって上昇し、先端に接続された制御棒を燃料集合体の間隙に挿入する。 In the case of a boiling water reactor, the control rod is inserted from the lower side of the core. When the control rod is not inserted, it is housed in a control rod guide tube disposed below the core support plate, and its lower end is connected to a drive piston of the control rod drive mechanism via a coupling. A water pressure control unit is connected to the control rod drive mechanism via a scram pipe, and the drive piston is driven by water pressure during automatic stop. When the automatic stop signal is transmitted, the scram valve of the water pressure control unit opens, and the nitrogen gas pressure stored in the nitrogen container is converted into water pressure by the accumulator, and this water power is transmitted to the scram piping to drive the control rod. Supplied to the mechanism. The drive piston of the control rod drive mechanism is raised by the supplied water pressure, and the control rod connected to the tip is inserted into the gap of the fuel assembly.
制御棒挿入機能の耐震性を試験によって確認する装置の一例が、特開2012-8085号公報に開示されている。本背景技術では、液体で満たされた容器内部に原子炉内の燃料を模擬した複数の模擬燃料および制御棒が収納され、該制御棒を前記模擬燃料間に挿入する制御棒駆動装置が取り付けられた試験容器と、該試験容器の周囲に設置された反力壁と、該反力壁に固定され、前記試験容器を一方向に振動させる加振機と、前記試験容器が前記一方向に沿って往復動可能に前記試験容器を支持する支持手段とを備えている。本技術により、試験容器を一方向に加振するときに加振機が負担する試験容器の鉛直荷重を低減させ、実際の地震に近い状態で試験容器を好適に加振することを試みている。 An example of an apparatus for confirming the seismic resistance of the control rod insertion function by a test is disclosed in Japanese Patent Laid-Open No. 2012-8085. In this background art, a plurality of simulated fuels and control rods simulating the fuel in a nuclear reactor are housed in a liquid-filled vessel, and a control rod driving device for inserting the control rods between the simulated fuels is attached. A test container, a reaction force wall installed around the test container, a vibrator fixed to the reaction force wall to vibrate the test container in one direction, and the test container along the one direction And a supporting means for supporting the test container so as to be reciprocally movable. With this technology, we are trying to reduce the vertical load of the test vessel that the shaker bears when oscillating the test vessel in one direction, and to suitably excite the test vessel in a state close to an actual earthquake. .
一方、制御棒駆動装置の性能試験装置の例が、非特許文献1に開示されている。本背景技術は、改良型制御棒駆動機構を対象としている。改良型制御棒駆動機構では、1台の水圧制御ユニットにスクラム配管を介して2台の制御棒駆動機構が接続されており、1台の水圧制御ユニットで2台の制御棒駆動機構を駆動する方式をとっている。非特許文献1の性能試験装置では、水圧制御ユニットや制御棒駆動機構、およびスクラム配管などの制御棒挿入システムを構成する機器について、実機と同様の接続形態とすることで、要求仕様に対する性能検証や寿命試験が実施されている。
On the other hand, Non-Patent Document 1 discloses an example of a performance test apparatus for a control rod drive device. This background art is directed to an improved control rod drive mechanism. In the improved control rod drive mechanism, two control rod drive mechanisms are connected to one water pressure control unit via a scram pipe, and two control rod drive mechanisms are driven by one water pressure control unit. The method is taken. In the performance test device of Non-Patent Document 1, performance verification for the required specifications is made by using the same connection form as the actual machine for the equipment constituting the control rod insertion system such as the hydraulic control unit, control rod drive mechanism, and scram piping. And life tests are being conducted.
特許文献１の制御棒挿入性耐震試験装置は、沸騰水型原子炉の制御棒挿入動作に関係する基本ユニット、すなわち４体の燃料集合体と１体の制御棒および１台の制御棒駆動機構が加振対象である。このため、１台の水圧制御ユニットで１台の制御棒駆動機構を駆動する従来型制御棒駆動機構や高速型制御棒駆動機構を用いた制御棒挿入システムに対しては、実機と同じ機器の接続形態で試験できる。しかしながら、例えば１台の水圧制御ユニットで２台の制御棒駆動機構を駆動する改良型制御棒駆動機構を用いた制御棒挿入システムに対しては、実機と同じ機器の接続形態で試験を行うためには、２つの基本ユニットを加振する試験設備が必要となる。特許文献１の制御棒挿入性耐震試験装置では、水圧制御ユニットのアキュムレータの容量や圧力を調整し、試験装置で発生する制御棒駆動力が実機条件の場合と同等あるいはそれ以下となるように設定し、制御棒の挿入性に対して同等あるいは厳しい条件での試験を行っている。制御棒駆動力を実機条件の場合よりも小さくなるように設定することは制御棒の挿入性に対して厳しい条件となるので安全側の評価につながるものの、水圧制御ユニットや制御棒駆動機構の水動力伝達系の挙動は実機と異なる。 The control rod insertion seismic test apparatus of Patent Document 1 is a basic unit related to control rod insertion operation of a boiling water reactor, that is, four fuel assemblies, one control rod and one control rod drive mechanism. Is the target of vibration. For this reason, a control rod insertion system using a conventional control rod drive mechanism or a high-speed control rod drive mechanism in which one control rod drive mechanism is driven by one hydraulic pressure control unit has the same equipment as the actual machine. Can be tested in connection form. However, for example, a control rod insertion system using an improved control rod drive mechanism that drives two control rod drive mechanisms with one hydraulic pressure control unit is tested in the same equipment connection form as the actual machine. Requires a test facility to vibrate two basic units. In the control rod insertion seismic test apparatus of Patent Document 1, the capacity and pressure of the accumulator of the hydraulic pressure control unit are adjusted so that the control rod driving force generated by the test apparatus is equal to or less than the actual machine conditions. In addition, tests are performed under the same or severe conditions as to the insertability of the control rod. Setting the control rod drive force to be smaller than in the actual machine conditions is a severe condition for the insertion performance of the control rod, leading to safety evaluation, but the water pressure of the hydraulic control unit and control rod drive mechanism The behavior of the power transmission system is different from the actual machine.
本発明の目的は、例えば改良型制御棒駆動機構のように、１台の水圧制御ユニットで複数台の制御棒駆動機構が駆動される制御棒挿入システムの動作を、各々１台の水圧制御ユニットと制御棒駆動機構で構成させる制御棒挿入システムを備えた耐震試験装置で模擬することである。
An object of the present invention is to control the operation of a control rod insertion system in which a plurality of control rod drive mechanisms are driven by one hydraulic control unit, such as an improved control rod drive mechanism, for each one hydraulic control unit. It is to simulate with a seismic test device equipped with a control rod insertion system composed of a control rod drive mechanism.
本発明は、改良型制御棒駆動装置を用いた制御棒挿入システムの耐震試験装置において、制御棒駆動機構が接続されていないスクラム配管系に，流量制御弁と制御装置を備えることを特徴とする。
The present invention provides a seismic test apparatus for a control rod insertion system using an improved control rod drive device, characterized in that a flow control valve and a control device are provided in a scram piping system to which no control rod drive mechanism is connected. .
本発明によれば、制御棒駆動機構が接続されていないスクラム配管系に，制御棒駆動機構が接続されたスクラム配管と同様の流量を発生させることができ、例えば改良型制御棒駆動機構のように１台の水圧制御ユニットで２台の制御棒駆動機構を駆動する制御棒挿入システムの動作を、各々１台の水圧制御ユニットと制御棒駆動機構で構成させる制御棒挿入システムを備えた耐震試験装置で模擬することができる。
According to the present invention, it is possible to generate a flow rate similar to that of a scrum pipe to which a control rod drive mechanism is connected to a scrum pipe system to which a control rod drive mechanism is not connected, such as an improved control rod drive mechanism. A seismic test equipped with a control rod insertion system in which the operation of a control rod insertion system that drives two control rod drive mechanisms with a single water pressure control unit is composed of one water pressure control unit and a control rod drive mechanism. Can be simulated with the device.
本発明は、原子力発電施設の原子炉で利用される制御棒の炉心への挿入機能の耐震性を試験する装置に関する。以下、各実施例について、図面を参照しながら説明する。 The present invention relates to an apparatus for testing the seismic resistance of a function of inserting a control rod into a core used in a nuclear power plant nuclear reactor. Hereinafter, each example will be described with reference to the drawings.
本実施例を図１〜図４により説明する。図１は本実施例による制御棒挿入性耐震試験装置の全体概略図を示す図で、図２は実施例１に係る制御棒駆動機構１１０、スクラム配管１２０、水圧制御ユニット１３０、および制御装置１６０の概略図である。本実施例は、改良型制御棒駆動機構を利用した沸騰水型原子炉の制御棒挿入システムの耐震試験装置を対象としている。 This embodiment will be described with reference to FIGS. FIG. 1 is a diagram showing an overall schematic diagram of a control rod insertion-type seismic test apparatus according to this embodiment, and FIG. 2 shows a control rod drive mechanism 110, a scram pipe 120, a water pressure control unit 130, and a control device 160 according to the first embodiment. FIG. This embodiment is intended for an earthquake resistance test apparatus for a control rod insertion system of a boiling water reactor using an improved control rod drive mechanism.
試験容器１０の内部には、原子炉内の燃料を模擬した模擬燃料２０、模擬燃料２０間の十字断面の間隙に挿入される制御棒３０、模擬燃料２０を設置する燃料支持金具４０、燃料支持金具４０を設置し、原子炉内の炉心支持板の一部を模擬した模擬炉心支持板５０、模擬燃料２０の上部を支持し、原子炉内の上部格子板の一部を模擬した模擬上部格子板６０、および非挿入時の制御棒３０が収められている案内管７０が設置されている。試験の対象は沸騰水型原子炉の炉心構造の１セル分のため、試験体は、模擬燃料２０は４体、制御棒３０・燃料支持金具４０・案内管７０は各１体で構成される。各模擬燃料２０には、接続治具９０を介して加振機８０が接続され、加振機８０は反力壁１００に固定されている。案内管７０の下方には制御棒駆動機構１１０が設置され、制御棒駆動機構１１０の駆動ピストンに制御棒３０が接続される。さらに制御棒駆動機構にはスクラム配管１２０を介して制御棒の駆動エネルギーを供給する水圧制御ユニット１３０が接続されている。実機の環境を模擬するため、試験容器１０は水で満たされており、試験容器１０に接続されたポンプ１４０とヒータ１５０によって内部水は実機と同様の高温・高圧状態に保たれる。 Inside the test vessel 10, a simulated fuel 20 that simulates the fuel in the nuclear reactor, a control rod 30 that is inserted into a cross-sectional gap between the simulated fuels 20, a fuel support bracket 40 for installing the simulated fuel 20, and a fuel support A metal fitting 40 is installed, a simulated core support plate 50 that simulates a part of the core support plate in the reactor, and an upper part of the simulated fuel 20, and a simulated upper lattice that simulates a part of the upper grid plate in the reactor. A guide tube 70 in which the plate 60 and the non-inserted control rod 30 are housed is installed. Since the test target is one cell of the core structure of the boiling water reactor, the test body is composed of four simulated fuels 20 and one control rod 30, fuel support bracket 40, and guide tube 70 each. . Each simulated fuel 20 is connected to a shaker 80 via a connection jig 90, and the shaker 80 is fixed to the reaction force wall 100. A control rod drive mechanism 110 is installed below the guide tube 70, and the control rod 30 is connected to the drive piston of the control rod drive mechanism 110. Further, a water pressure control unit 130 that supplies drive energy for the control rod is connected to the control rod drive mechanism via a scram pipe 120. In order to simulate the environment of the actual machine, the test container 10 is filled with water, and the internal water is maintained at the same high temperature and high pressure as the actual machine by the pump 140 and the heater 150 connected to the test container 10.
図２は、実施例１に係る制御棒駆動機構１１０、スクラム配管１２０、水圧制御ユニット１３０、および制御装置１６０の概略図である。分岐部２００の上流側には、窒素ガスが蓄えられた窒素容器１７０と、窒素ガスの圧力を水圧に変換するアキュムレータ１８０が接続されている。この図に示すように、スクラム配管１２０には、水圧制御ユニット１３０のスクラム弁１９０よりも下流に分岐部２００がある。分岐部２００より下流の一方のスクラム配管は制御棒駆動機構１１０に接続されている。他方のスクラム配管には流量制御弁２１０が接続され、さらにその下流のスクラム配管はダンプタンク２２０に開放されている。流量制御弁２１０の動作は、制御装置１６０により制御される。スクラム配管１２０には、分岐部２００と制御棒駆動機構１１０の間に、例えばタービン式流量計のような流量センサ２３０が設置されている。制御装置１６０は、この流量センサ２３０で計測された流量を目標値として流量制御弁２１０を駆動することにより、分岐部より下流のスクラム配管において、制御棒駆動機構が接続されていないスクラム配管に、制御棒駆動機構が接続されたスクラム配管と同様の流量を発生させることができる。これにより、分岐部２００より下流のスクラム配管の双方に制御棒駆動機構が接続された場合と等量の流量が供給されるため、動力源である水圧制御ユニット１３０には、２台の制御棒駆動機構が接続された場合と同じ負荷が作用する。したがって、本実施例により、１台の水圧制御ユニットで２台の制御棒駆動機構を駆動する改良型制御棒駆動機構を用いた制御棒挿入システムの動作を、各々１台の水圧制御ユニットと制御棒駆動機構で構成させる制御棒挿入システムを備えた耐震試験装置で模擬することができる。 FIG. 2 is a schematic diagram of the control rod drive mechanism 110, the scram piping 120, the water pressure control unit 130, and the control device 160 according to the first embodiment. A nitrogen container 170 that stores nitrogen gas and an accumulator 180 that converts the pressure of the nitrogen gas into water pressure are connected to the upstream side of the branching unit 200. As shown in this figure, the scram pipe 120 has a branching portion 200 downstream of the scram valve 190 of the water pressure control unit 130. One scrum pipe downstream from the branching section 200 is connected to the control rod drive mechanism 110. A flow control valve 210 is connected to the other scrum pipe, and a scram pipe downstream thereof is opened to the dump tank 220. The operation of the flow control valve 210 is controlled by the control device 160. In the scram piping 120, a flow sensor 230 such as a turbine type flow meter is installed between the branch portion 200 and the control rod drive mechanism 110. The control device 160 drives the flow rate control valve 210 with the flow rate measured by the flow rate sensor 230 as a target value, so that in the scrum piping downstream from the branch portion, the scram piping to which the control rod drive mechanism is not connected A flow rate similar to that of the scram pipe to which the control rod drive mechanism is connected can be generated. As a result, the same amount of flow is supplied as when the control rod drive mechanism is connected to both of the scram pipes downstream from the branching portion 200, so that the hydraulic control unit 130 as the power source has two control rods. The same load is applied as when the drive mechanism is connected. Therefore, according to the present embodiment, the operation of the control rod insertion system using the improved control rod drive mechanism that drives two control rod drive mechanisms with one hydraulic control unit is controlled with one hydraulic control unit each. It can be simulated by a seismic test device equipped with a control rod insertion system configured by a rod drive mechanism.
図３は、実施例２に係る制御棒駆動機構１１０、スクラム配管１２０、水圧制御ユニット１３０、および制御装置１６０の概略図である。本実施例では、分岐部２００よりも下流のスクラム配管において、制御棒駆動機構１１０の入口部に、例えばダイヤフラム式圧力計のような圧力センサ２４０ａを設けている。さらに、ダンプタンク２１０に開放されるスクラム配管の出口部にも圧力センサ２４０ｂを設けている。そして、制御装置１６０は、この圧力センサ２４０ａで計測された圧力を目標値として、この値に圧力センサ２４０ｂで計測される圧力が一致するように流量制御弁２１０を駆動する。分岐部２００より下流の双方のスクラム配管において、分岐部と配管末端の圧力差が同じであれば、両配管の流量は等量である。したがって、実施例２によっても、制御棒駆動機構が接続されていないスクラム配管に、制御棒駆動機構が接続されたスクラム配管と同様の流量を発生させることができ、１台の水圧制御ユニットで２台の制御棒駆動機構を駆動する改良型制御棒駆動機構を用いた制御棒挿入システムの動作を、各々１台の水圧制御ユニットと制御棒駆動機構で構成させる制御棒挿入システムを備えた耐震試験装置で模擬することができる。 FIG. 3 is a schematic diagram of the control rod drive mechanism 110, the scram piping 120, the water pressure control unit 130, and the control device 160 according to the second embodiment. In the present embodiment, a pressure sensor 240 a such as a diaphragm pressure gauge is provided at the inlet of the control rod drive mechanism 110 in the scram pipe downstream from the branching portion 200. Furthermore, a pressure sensor 240b is also provided at the outlet of the scrum pipe opened to the dump tank 210. Then, the control device 160 uses the pressure measured by the pressure sensor 240a as a target value, and drives the flow control valve 210 so that the pressure measured by the pressure sensor 240b matches this value. In both scram pipes downstream from the branch part 200, if the pressure difference between the branch part and the pipe end is the same, the flow rates of both pipes are equal. Therefore, according to the second embodiment, the same flow rate as that of the scram pipe to which the control rod drive mechanism is connected can be generated in the scrum pipe to which the control rod drive mechanism is not connected. Seismic test equipped with control rod insertion system that controls the operation of the control rod insertion system using the improved control rod drive mechanism that drives the control rod drive mechanism of each stand by one hydraulic control unit and control rod drive mechanism each Can be simulated with the device.
図４は、実施例３に係る制御棒駆動機構１１０、スクラム配管１２０、水圧制御ユニット１３０、および制御装置１６０の概略図である。本実施例は、スクラム配管１２０が複数に分岐している。そして、分岐部２００より下流のスクラム配管のうち、１つのラインにのみ制御棒駆動機構１１０を接続し、その他のスクラム配管はダンプタンク２２０に開放され、その途中に流量制御弁２１０が接続されている。それぞれの流量制御弁２１０の動作は、制御装置１６０により制御される。実施例１と同様に、スクラム配管１２０の分岐部２００と制御棒駆動機構１１０の間には、流量センサ２３０が設置され、制御装置１６０は、この流量センサ２３０で計測された流量を目標値としてすべての流量制御弁２１０を駆動することにより、分岐部より下流のスクラム配管において、制御棒駆動機構が接続されていないすべてのスクラム配管に、制御棒駆動機構が接続されたスクラム配管と同様の流量を発生させることができる。分岐部２００より下流のすべてのスクラム配管に等量の流量が供給されるため、動力源である水圧制御ユニット１３０には、複数台の制御棒駆動機構が接続された場合と同じ負荷が作用する。本実施例により、１台の水圧制御ユニットで複数台の制御棒駆動機構を駆動する制御棒挿入システムについても、各々１台の水圧制御ユニットと制御棒駆動機構で構成させる制御棒挿入システムを備えた耐震試験装置で模擬することができる。なお、本実施例の流量制御弁の制御方法については、実施例２のような方法をとることもできる。すなわち、ダンプタンク２１０に開放されるスクラム配管のそれぞれの出口部の圧力が、制御棒駆動機構１１０の入口部の圧力に一致するように流量制御弁２１０を駆動することで、分岐部と配管端部の差圧が等しくなり、制御棒駆動機構が接続されていないスクラム配管に制御棒駆動機構が接続されたスクラム配管と同様の流量を発生させることができる。
FIG. 4 is a schematic diagram of the control rod drive mechanism 110, the scram pipe 120, the water pressure control unit 130, and the control device 160 according to the third embodiment. In the present embodiment, the scram pipe 120 is branched into a plurality. The control rod drive mechanism 110 is connected to only one line of the scram pipes downstream from the branch part 200, the other scrum pipes are opened to the dump tank 220, and the flow control valve 210 is connected to the middle of the scram pipes. Yes. The operation of each flow control valve 210 is controlled by the control device 160. As in the first embodiment, a flow rate sensor 230 is installed between the branch portion 200 of the scram pipe 120 and the control rod drive mechanism 110, and the control device 160 uses the flow rate measured by the flow rate sensor 230 as a target value. By driving all the flow rate control valves 210, the same flow rate as that of the scram pipe in which the control rod drive mechanism is connected to all the scrum pipes to which the control rod drive mechanism is not connected in the scrum pipe downstream from the branching portion. Can be generated. Since an equal flow rate is supplied to all the scram pipes downstream from the branching section 200, the same load as when a plurality of control rod drive mechanisms are connected is applied to the hydraulic pressure control unit 130 that is a power source. . According to the present embodiment, the control rod insertion system that drives a plurality of control rod drive mechanisms with one water pressure control unit also includes a control rod insertion system that is configured by one water pressure control unit and a control rod drive mechanism. It can be simulated with the seismic test equipment. In addition, about the control method of the flow control valve of a present Example, the method like Example 2 can also be taken. That is, by driving the flow control valve 210 so that the pressure at each outlet of the scram pipe opened to the dump tank 210 matches the pressure at the inlet of the control rod drive mechanism 110, the branch portion and the pipe end Accordingly, the same flow rate as that of the scram pipe in which the control rod drive mechanism is connected to the scrum pipe to which the control rod drive mechanism is not connected can be generated.
