Apparatus for falling-shock absorption of control rod of nuclear reactor

摘要

There is provided an apparatus for drop impact absorption of a control rod of a nuclear reactor that can maintain the appropriate drop speed during the free drop of the control rod to quickly stop the operation of the nuclear reactor, and can reduce the drop impact of the control rod that occurs at the last stage when the control rod drops. An apparatus for drop impact absorption of a control rod of a nuclear reactor according to an aspect of the invention includes a fixed frame disposed at an upper side of the core of the nuclear reactor, and a impact absorbing device installed at the fixed frame to reduce the drop impact with respect to a control rod mounted at the lower part during the free drop of the control rod to be inserted into the core of a nuclear reactor.
