PRIMARY PRESSURE-PROOF TEST PRESSURE DEVICE FOR REACTOR PRESSURE VESSEL ACCESSORY PIPELINE

摘要

PURPOSE:To provide a primary pressure-proof test pressure device for a reactor pressure vessel accessory pipeline automatically securing the test normal pressure and reducing the load of an operating worker by using the control rod driving mechanism pump and control rod driving mechanism pipeline of a plant main facility and a temporary facility used when the control rod driving mechanism pipeline is washed. CONSTITUTION:A primary pressure-proof test pressure device for a reactor pressure vessel accessory pipeline is constituted of a control rod driving mechanism system provided with a control rod driving mechanism pump 14 connected to a reactor water feed pipeline 9 communicated with a reactor pressure vessel 4 at one end, a pressure reducing valve 12, a flow regulating valve 11, and a driving water pipeline 10 and a purifying facility provided with a tank 16, a heat exchanger 17, a filter 18, a pressure control valve 20, and a pipeline 21 arranged for purifying the control rod driving mechanism system.
