RCP TBA 비상 급유장치 및 그 설치방법{Oil supply device for RCP TBA for emergency and installation method of it}RCP TBA emergency oil supply device and its installation method {Oil supply device for RCP TBA for emergency and installation method of it}

본 발명은 원전의 RCP(Reactor Coolant Pump, 원자로냉각재펌프) TBA(Thrust Bearing Assembly) 비상 급유장치로서, RCP TBA로 윤활유를 공급하는 HPU(Hydraulic Power Unit)가 오작동 시 사용할 수 있는 비상 급유장치와 그 설치방법에 관한 것이다.The present invention is an RCP (Reactor Coolant Pump) TBA (Thrust Bearing Assembly) emergency refueling device of a nuclear power plant. It is about the installation method.

원전의 RCP는 원자로 냉각재에 순환력을 제공하는 기기로서, 원자로를 지나 증기발생기에서 열교환 된 냉각재를 다시 원자로로 순환시킨다. RCP는 내부에 TBA를 포함하며, TBA는 모터와 펌프 축 사이에 설치되어 펌프의 축방향(Thrust) 하중과 레이디얼(radial) 하중을 지지하는 Thrust bearing 조립체이다.The RCP of a nuclear power plant is a device that provides circulation power to the reactor coolant, and circulates the coolant that has been heat-exchanged in the steam generator through the reactor and back to the reactor. The RCP includes the TBA inside, and the TBA is a thrust bearing assembly installed between the motor and the pump shaft to support the axial load and the radial load of the pump.

TBA는 평상시 HPU에 의해 윤활유를 공급받아 일정한 충유 상태를 유지한다. TBA에 오일이 공급되지 않을 경우, RCP가 정지되어 발전 정지 사고가 발생할 수 있다. 실제로 미국의 Palo Verde 원전은 RCP TBA에 오일이 제대로 공급되지 않아 발전 정지 사고를 겪은 바 있다. 따라서, RCP TBA 오일 공급 시스템에 이상이 있을 경우를 대비하여 긴급하게 사용 가능한 비상 급유장치의 필요성이 있다.The TBA is normally supplied with lubricating oil by the HPU and maintains a constant state of filling. If oil is not supplied to the TBA, the RCP is stopped and a power generation stop accident may occur. In fact, the Palo Verde nuclear power plant in the US suffered a power generation shutdown due to insufficient oil supply to the RCP TBA. Therefore, there is a need for an emergency refueling device that can be used urgently in case there is an abnormality in the RCP TBA oil supply system.
