Title:
COMPREHENSIVE FORTIFICATION SYSTEM FOR COLD SOURCE SAFETY OF NUCLEAR POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2024/051023
Kind Code:
A1
Abstract:
Disclosed in the present invention is a comprehensive fortification system for cold source safety of a nuclear power plant. The system comprises a first-stage damming unit, a second-stage damming unit, a third-stage damming unit and a fourth-stage damming unit which are sequentially arranged in the direction of a water flow entering the nuclear power plant; the first-stage damming unit comprises a harbor entrance damming net arranged at the intake and at least two harbor entrance buoy monitoring units arranged outside the harbor entrance damming net; the second-stage damming unit comprises a second-stage damming net and a first net-bag damming net which are spaced apart in the water flow direction and are used for carrying out full-section damming on seawater passing through an intake open channel; the third-stage damming unit comprises a second net-bag damming nets; and the fourth-stage damming unit comprises a final net. According to the comprehensive fortification system for cold source safety of a nuclear power plant of the present invention, by means of the sequential arrangement of the four stages of damming units, comprehensive treatment such as monitoring, early warning, damming, cleaning, etc., is carried out on disaster-causing objects such as marine organisms and floating objects carried in an intake water flow, such that the disaster-causing objects are prevented from blocking a nuclear power plant filtering device.
