Description

Spherical structure outer surface working method and system thereof {Shere Type Structure Outer Surface Working Method and System thereof}

The present invention relates to a method and a system for working the outer surface of a spherical structure, and more particularly, in the process of processing and welding pipes, etc. to remove and reattach pipes, etc. coupled to the outer surface of a large spherical structure, more effectively and stably. It relates to a method and system for working on the outer surface of a spherical structure with an improved structure to work with.

Pipes that guide the flow of fluids including gases and liquids are coupled to mechanical facilities or devices.

These pipes age with use and need to be replaced.

In a nuclear power plant, facilities of a primary system, which is a system directly related to radiation, and a secondary system, which is a system not related to radiation, exist. The primary system includes a Nuclear Steam Supply System (NSSS), a reactor safety related system, a reactor auxiliary system, and other radiation related auxiliary systems. Secondary systems include turbines and generators, their auxiliary systems, and other non-radiation systems.

NSSS includes the reactor, pressurizers, steam generators and coolant pumps. The reactor pressure vessel stores nuclear fuel and provides a place where nuclear reactions take place, and the pressurizer controls the pressure in the primary system. The steam generator converts water into steam by exchanging heat between the water cooled in the secondary system and the cooling water heated by the nuclear fuel, and the coolant pump serves to supply the cooled coolant back to the reactor after heat exchange.

The reactor vessel is composed of a lower vessel and an upper reactor head, and includes a large number of small and medium-sized pipes or nozzles, such as a nozzle related to a removal rod driver, in addition to a large nozzle through which coolant is introduced and discharged. In addition, there are many small pipes or nozzles of about 1 inch in the reactor, the steam generator, the pressurizer, and the main pipe between them.

A plurality of pipes are coupled to the lower part of the reactor, and when these pipes are aged, they must be replaced.

In particular, when replacing an old pipe at the bottom of a spherical nuclear reactor, it is desirable to stably maintain the position of the pipe and the set angle.
