Update on the Development of Ultra-Low Residual Resin for Condensate Polishing Applications

摘要

This paper reports on the application of a strongly basic anion resin with ultra-low residual chloride content. The first resin charge installed five years ago at a pressurized water reactor nuclear power station remains in service, having produced more than 26 billion liters of condensate without any regeneration and with a current chloride leakage of significantly less than 10 ng ? L"1. The development and testing of an ultra-low sulfate strongly acidic cation resin, particularly for use in condensate polishers in boiling water reactor units, is also discussed. Data from plant trials is presented.
