A modular construction method for nuclear power reactor cavity pool

Abstract

The invention relates to a modular construction method for a nuclear power reactor chamber pool, the construction method comprising the first step, prefabrication of the inner supporting steel frame module; the second step, prefabrication of the stainless steel cladding module; the third step, the stainless steel cladding module and the inner The supporting steel frame module assembly; the fourth step, on-site assembly of the reactor cavity module; the fifth step, the overall hoisting of the module in place; the sixth step, concrete pouring. Compared with the traditional construction technology of nuclear power reactor cavity pool, this modular construction technology not only The formwork support on one side is reduced, and the process of keel installation and secondary plastering is also reduced. While meeting the construction needs, it can reduce the time spent on construction and create greater economic and social benefits.

Description

technical field [0001] The invention relates to the field of building construction methods, in particular to a modular construction method for nuclear power reactor cavity pools. Background technique [0002] The traditional nuclear power reactor cavity pool construction method is designed as the "post-pasting method" construction. It is necessary to complete the primary concrete pouring of the pool first, then install the keel on the primary concrete, and then lay the stainless steel cladding after the secondary plastering and leveling. This traditional post-pasting construction technique is to construct the stainless steel cladding of the pool cavity after the dome is hoisted. The prefabrication and installation of the cladding of the stainless steel pool start late, and there are many on-site installation procedures and a long construction period, which is different from the stack cavity. There are many cross-operations in other constructions, which need to occupy more cr...

This traditional post-pasting construction technique is to construct the stainless steel cladding of the pool cavity after the dome is hoisted. The prefabrication and installation of the cladding of the stainless steel pool start late, and there are many on-site installation procedures and a long construction period, which is different from the stack cavity. There are many cross-operations in other constructions, which need to occupy more critical paths for the construction of the stack cavity, which has a direct impact on the lead-in time of the main equipment pressure vessel

This traditional "post-post method" construction technology has a relatively large construction period risk for new nuclear power reactors, especially the construction of the first reactor.
