The present invention relates to a three-dimensional integrated seismic isolation device for a nuclear power facility with a dynamic vibration absorber and, more specifically, to a three-dimensional integrated seismic isolation device for a nuclear power facility to which a design for absorbing a vertical resonance vibration response of a structure by installing a dynamic vibration absorber is applied. According to the present invention, a design for absorbing a vertical resonance vibration response of a structure by installing a dynamic vibration absorber in a seismic isolation device is applied, so the seismic isolation device minimizes vertical seismic isolation efficiency reduction around a vertical natural frequency of the structure. 본 발명은 동흡진기를 장착한 원전설비용 3차원 통합 면진장치에 관한 것으로서, 더욱 상세하게는 동흡진기를 설치하여 구조물의 상하방향 공진진동응답을 흡수하는 설계를 적용한 원전설비용 3차원 통합 면진장치에 관한 것이다. 본 발명에 의하면, 면진장치에 동흡진기를 설치하여 구조물의 상하방향 공진진동응답을 흡수하는 설계를 적용함으로써, 구조물의 수직방향 고유진동수 근방에서 수직방향 면진효율 감소를 최소화하는 면진장치를 제공한다.
