Disclosed is a device to measure a size of a reactor vessel. According to an embodiment of the present invention, the device to measure the size of the reactor vessel comprises: a base part placed on an inner floor surface of a forged reactor vessel; an internal diameter measuring part including a first extended part, extended from the base part in a radial direction of the reactor vessel, and a first gauge placed on an end of the first extended part in order to measure an internal diameter of the reactor vessel; and an external diameter measuring part including a second extended part, extended from a top of the base part to the outside in the radial direction of the reactor vessel, and a second gauge placed on an end of the second extended part in order to measure an external diameter of the reactor vessel. As such, the present invention is capable of improving a reliability of the measured size data. |
