Description

Technical Field

[0001] This invention belongs to the field of nuclear power plant maintenance equipment, and specifically relates to a clustering mechanism and component pool. Background Technology

[0002] In nuclear power units, control rods are used to control the unit's operating power and shutdown. Control rod drive rods provide power for their movement, and control rod guide tubes provide guidance. Each unit has dozens of control rod drive rods. As the nuclear power unit's operating time increases, the control rod guide tubes may show wear, requiring inspection / replacement. One prerequisite for control rod guide tube inspection / replacement is removing the control rod drive rods from the CRGT (Construction Control Rod Mounting Unit). Current technology utilizes the original storage area for lower in-reactor components in the component pool, making it impossible to store lower in-reactor components and drive rods simultaneously. However, critical path operations such as RPV (Reverse Vehicle Inspection) require the lower in-reactor components to be lifted out and stored in the component pool. Therefore, CRGT inspection / replacement cannot be performed concurrently with RPV inspection, impacting overhaul schedules. There is an urgent need for a clustering mechanism design that does not occupy usable space in the component pool. Summary of the Invention
