PRIMARY SYSTEM FLOW MEASURING DEVICE FOR SODIUM-COOLED FAST REACTOR

摘要

PURPOSE: A primary flow meter for a sodium-cooling faster reactor is provided to back-calculate the flow by measuring the pressure difference between the rear side and the front side. CONSTITUTION: A primary pump is placed inside the main container body of a nuclear reactor. Sodium flows in through an inlet hole. A front side (172) collides head-on with the flow of the sodium. A rear side (174) is located at the rear of the front side. The rear side generates the rear-side flow of the sodium.
