EX-VESSEL NEUTRON DOSIMETRY EQUIPMENT OF CHANGE POSSIBLE REACTOR VESSEL

摘要

PURPOSE: Ex-vessel neutron dosimetry equipment is provided to watch an ex-vessel neutron dosimetry of a nuclear reactor vessel by arranging a plurality of monitoring capsules in the exterior wall of the nuclear reactor vessel. CONSTITUTION: A plurality of monitoring capsules(20) are arranged in the exterior wall of a nuclear reactor(10) at a predetermined interval. A support structure apparatus comprises a support rod, a chain clamp, a support chain, and a support structure stand. The support rod supports an ex-vessel neutron dosimetry guard. The chain clamp prevents the movement of a bead chain. The support chain secures the support rod along the upper wall of the nuclear reactor. The support structure stand secures the support rod, the bead chain, the chain clamp, and the support chain.
