Description

원자력발전소 금속파편감시계통 공압형 충격발생장치{air pressure type impact test apparatus for loose parts monitoring system of nuclear power plant}Air pressure type impact test apparatus for loose parts monitoring system of nuclear power plant}

본 발명은 원자력발전소 금속파편감시계통 공압형 충격발생장치에 관한 것으로, 특히 원자력발전소의 금속파편감시계통의 건전성을 확인하기 위하여 실시하는 강구충격시험에 사용되는 원자력발전소 금속파편감시계통 공압형 충격발생장치에 관한 것이다.The present invention relates to a pneumatic shock generating device for a metal fragment reduction watch cylinder of a nuclear power plant. In particular, a metal fragment reduction watch pneumatic shock generation used for a steel ball impact test performed to verify the integrity of the metal fragment reduction watch cylinder of a nuclear power plant. Relates to a device.

일반적으로 원자력발전소의 원자로냉각재계통은 방사능물질의 누출을 방지하기 위한 압력경계를 이루고 있어, 상기 원자로냉각재계통의 건전성 확보유지는 원전의 안전과 직결된다. In general, the reactor coolant system of the nuclear power plant forms a pressure boundary for preventing the leakage of radioactive material, and maintaining the integrity of the reactor coolant system is directly connected to the safety of nuclear power plants.

원자로냉각재계통 내로 외부에서 이물질(foreign material)이 유입되거나 또는 원자로냉각재계통에 설치된 각종 기기의 부품이 이완/이탈되면, 금속파편(loose part) 상태로 고속의 냉각재 유동과 함께 원자로냉각재계통 내를 이동하면서, 원자로 내부 구조물 및 핵연료집합체, 원자로냉각재 펌프의 임펠러, 증기발생기의 튜브시트, 전열관 등에 심각한 영향을 미쳐 원자력발전소 안전성을 위협한다.When foreign material flows into the reactor coolant system from outside or the components of various equipment installed in the reactor coolant system are relaxed / detached, it moves in the reactor coolant system with high speed coolant flow in a loose part state. At the same time, the internal structure and fuel assembly, the impeller of the reactor coolant pump, the tubesheet of the steam generator, and the heat pipes threaten nuclear power plant safety.

금속파편감시계통(LPMS)은 충격파감지센서(가속도센서)를 이용하여, 원자로냉각재 내부에서 발생하는 금속파편의 충격신호를 탐지하여 원자로냉각재계통의 손상을 조기에 방지하고자 하는 감시장치로서, 원전 안전성 유지를 위한 필수적인 장치이다.LPMS is a monitoring device that detects the impact signal of metal fragments generated inside the reactor coolant by using the shock wave sensor (acceleration sensor) to prevent damage to the reactor coolant system at an early stage. It is an essential device for maintenance.

금속파편은 기계적 손상 또는 피로, 부식 등으로 인하여 원자로냉각재계통 내부의 기기에서 이탈되어 발생하거나 원전건설, 핵연료 재장전시 또는 정비시에 원자로냉각재계통 외부로부터 유입되어 발생된다.Metal debris is generated from the equipment inside the reactor coolant system due to mechanical damage, fatigue, corrosion, etc., or from outside the reactor coolant system during nuclear power plant construction, nuclear fuel reloading, or maintenance.

금속파편감시계통의 기본 기능은 원자로냉각재계통 내부에 금속파편이 존재할 때 충격신호를 선별 취득하고, 저장하여 금속파편에 의한 충격신호 여부를 판단하여, 이에 대한 경보를 발생하고, 금속파편의 특성, 충격 위치 등을 결정하는 진단정보를 제공하는 것이다.The basic function of the metal debris watch cylinder is to acquire and store shock signals when metal fragments are present in the reactor coolant system, determine whether the impact signal is caused by metal fragments, and generate an alarm for them. It is to provide diagnostic information for determining the impact location and the like.

여기서, 상기 금속파편감시계통은 여러 개의 센서가 설치되어 있으며, 사용의 편리성이나 견고성 등에서 PIEZO 가속도 센서가 사용된다. Here, the metal fragment watch is equipped with a plurality of sensors, PIEZO acceleration sensor is used in the ease of use, robustness, and the like.

금속이물질은 구조물에 부딪히면서 충격을 구조물에 주고, 이 충격은 여러 개의 센서에 의해 신호로 검출되며, 각각의 신호 모양으로부터 금속파편(loose part)의 위치, 질량 등을 분석한다.The metal foreign object hits the structure and gives an impact to the structure, which is detected as a signal by several sensors, and analyzes the position, mass, etc. of the metal parts from each signal shape.

따라서 금속파편감시계통은 원자력발전소의 안전성에 매우 중요한 계통이고, 주기적인 검증이 필요하지만 운전 중 전 설비의 건전성을 시험할 수 있는 방법이 현재로는 없는 문제점이 있다.Therefore, the metal debris watch tube is a very important system for the safety of nuclear power plants, and periodic verification is required, but there is a problem that there is currently no method for testing the integrity of all equipment during operation.

즉, 종래의 방법은 원자력발전소 운전을 정지한 기간에 강구를 실에 매달아 충격위치에 때리는 방법을 사용하는데 충격량으로부터 역산되는 위치에 강구를 놓고, 자유 낙하시키거나 반원운동(진자운동)을 시켜 구조물에 충격을 주고 있다.In other words, the conventional method uses a method in which a steel ball is hung on a thread in a period where the operation of a nuclear power plant is stopped, and a steel ball is placed at an impact position. Is shocking.

이 방법은 피시험체가 수평으로 놓여 있거나 수직으로 놓여 있을 때 유효한 방법이지만 시험 오차가 크고, 수직 상 방향으로는 시험을 할 수 없고, 또 원자로가 가동하지 않더라도 원자로 하부 부위는 방사선 준위가 너무 높아서 작업자가 접근하여 시험을 할 수 없다.This method is effective when the test object is placed horizontally or vertically, but the test error is large, the test cannot be performed in the vertical direction, and even if the reactor is not operated, the lower part of the reactor has a high radiation level. Cannot access and test.

또한, 원자로 가동 중에는 작업자가 원자로에 접근할 수 없어서 테스트할 수 있는 방법이 현재로는 없는 문제점이 있다.In addition, there is a problem that there is currently no way to test because the operator can not access the reactor during operation.
