Abstract

The control element drive mechanism (CEDM) is an electro-mechanical device to control reactivity of the nuclear reactor. The conventional CEDM was installed on a nozzle of the reactor vessel closure head as an ex-vessel type. However, there have been demands for an in-vessel CEDM to fundamentally eliminate the rod ejection accident. Conceptual design of the in-vessel CEDM, which was developed based on the existing technology of the ex-vessel CEDM, is introduced in this paper.

제어봉구동장치는 원자로의 반응도를 제어하기 위한 전기기기이다. 기존 제어봉구동장치는 원자로 외장형으로 원자로덮개의 노즐에 설치되었다. 그러나 최근에는 제어봉인출 사고를 근본적으로 배제하기 위한 내장형 제어봉구동장치의 필요성이 대두되어 왔다. 본 논문에서는 기존의 자석잭 방식 외장형 제어봉구동장치를 응용하여 원자로 내장형 제어봉구동장치를 개발하는 개념설계를 소개한다.
