Description
technical field [0001] The invention belongs to the field of maintenance of nuclear power plant reactors, and in particular relates to a pressurization and recycling device for a pressure shell hydraulic test medium and a method thereof. Background technique [0002] The first phase of Tianwan Nuclear Power Plant consists of two VVER-1000 units, and the reactor is a B-428 reactor. A single unit is now equipped with 103 sets of ШЭМ-3 control rod drive mechanisms, which are used to move the control rod up and down and fix it at the uppermost, lowermost or middle position. The position information of the control rod can be known through the position indicator. The control rod driving mechanism inserts or lifts the control rods from the core to realize power start-up, power control and shutdown. During a reactor scram, the drive mechanism is de-energized and the control rods fall to the bottom. The control rod driving mechanism is composed of five parts: electromagnet assembly...
