Research on Water Intake, Usage and Drainage Impact Demonstration for Coastal Nuclear Power Plants

Abstract

Nowadays, all nuclear power plants including constructed ones and those under construction are coastal plants in China. Water resources assessment of coastal nuclear power plants in China is based on the Guidelines for Water Resources Assessment of Construction Projects (SL 322). However, the specific guideline for water resources assessment of coastal nuclear power plant projects, the Guidelines for Water Resources Assessment of Coastal Nuclear Power Plant Projects, has not yet issued at present. According to the plans for intake, usage and discharge of water proposed by the owner of coastal nuclear power plants, it was proposed that the general requirements for water resources assessment by considering characteristics of intake, usage and discharge for water. In this study, Tianwan nuclear power plant was chose as the case study. Researches on yields of intake and usage of water, and the impact of water discharge for this nuclear power plant could provide the reference for water intake and usage rationalities, as well as the impact analysis caused by water discharge of coastal nuclear power plants.
