Analysis of Discharge Activity Thresholds of Liquid Waste Discharge System for Qinshan Nuclear Power Plant PhaseⅡ Extension Project

On line monitoring thresholds of liquid waste discharge and activity concentration of storage tank discharge of nuclear island liquid waste discharge system and conventional island liquid waste discharge system were analyzed. Total radiation dose control of liquid waste discharge system and on line monitoring demand of liquid waste discharge concentration were described. Finally, the target of liquid waste discharge concentration for Qinshan Nuclear Power Plant PhaseⅡ extension project was determined.
