Traversing incore probe valve support and traversing incore probe system

摘要

According to an embodiment, a traversing incore probe valve support has: a valve bed fixed to a traversing incore probe valve provided in a traversing incore probe guide tube extending to outside of a reactor containment vessel; a stand provided on a floor surface outside the reactor containment vessel; and a displacement allowing member that connects the stand and valve bed in such a manner that they can be displaced in an axial direction of the traversing incore probe guide tube. The displacement allowing member may include: a lower slide rail fixed to the stand valve bed and having an upward contact surface; and an upper slide rail fixed to the valve bed and having a downward contact surface that can be slid in the axial direction of the traversing incore probe guide tube while contacting the upward contact surface.
