Title:
FLOOR FINISHING METHOD FOR NUCLEAR POWER PLANT
Document Type and Number:
Japanese Patent JP2701614
Kind Code:
B2
Abstract:
PURPOSE: To reduce the cost of flooring materials and the working cost by applying thermal spraying to a concrete floor surface in a nuclear power plant with high-temperature resistant metal, ceramic or the like so as to form a film having a suitable thickness.
CONSTITUTION: A floor member for a nuclear power plant is formed by the thermal spraying of a concrete floor material with heat-resistant metal, ceramic, enamel or the like so as to form lining films 3, 3a. Gas thermal spraying for a metal material is made in such a way that acetylene gas and oxygen are mixed and burnt being blown onto a concrete floor surface 2 or that d.c. arc is produced between materials to be thermally sprayed so as to blow molten metal in the form of fine particles. Further, when a material having a high melting point, such as ceramic, is thermally sprayed, a plasma thermal spraying is used. With this arrangement, it is possible to reduce the cost of material for the concrete floor surface 2.
