Complete instruments for failure related component handling of pressurized water reactor nuclear power plant

Abstract

The invention relates to equipment related to pressurized water reactor nuclear power plant, in particular to complete instruments for failure related component handling of a pressurized water reactor nuclear power plant, comprising a gripping tool, a special adaptor and a multifunctional guide comb. The gripping tool is a hook, and the upper end of the hook is connected with a steel wire rope; the special adaptor is a fixed special adaptor for related components or a special adaptor for a control rod component, the frame end face of the special adaptor is provided with a positioning hole and an anti-misplace hole, and four edges of the end face are respectively provided with positioning plates which can be closely attached to the inner wall of a fuel storage cell and can be matched grippers of a spend fuel component gripping apparatus; and the multifunctional guide comb comprises an operation pole, two structures are arranged on two sides of the end part of the operation pole vertical to the surface of the operation pole, one structure is two comb shaped structures which are used for guiding a failure control rod body to ensure that the control rod is uniformly dispersed, while the other structure is two parallel-rod structure which plays a role in guiding and drawing rod bodies of failure related components, wherein end parts of the parallel rods are bent outwards respectively.

Description

technical field [0001] The invention relates to related equipment of a pressurized water reactor nuclear power plant, in particular to a complete set of tools for handling fault related components of a pressurized water reactor nuclear power plant. Background technique [0002] The relevant components of the PWR nuclear power plant are stored in the spent fuel pool by mating and inserting in the fuel assembly or the adapter. According to the behavior in the reactor, they can be divided into the following two categories: movable (control rod assembly) and fixed (primary neutron source assembly, resistance plug assembly, burnable poison assembly and secondary neutron source assembly), in the PMC system (nuclear fuel transportation and storage system), are equipped with corresponding grippers to grab and store them. These grippers are equipped with a positioning system and a guiding system so that only the relevant components within the fuel assembly or adapter with positioning...
