CORROSION AND PROTECTION OF DEBRIS FILTERS IN CRF SYSTEM OF LING-AO NUCLEAR POWER STATION
岭澳核电站CRF系统碎石过滤器的腐蚀与防护

With morphology observation and chemical composition analyses by SEM and EDS as well as immersion test and corrosion potential measurement,the corrosion of debris filters in the CRF system of Ling Ao Nuclear Power Station was studied.The primary cause was regarded as microbion induced corrosion.After a series of anti-corrosion measures consisted mainly of cathodic protection (CP) were applied to debris filters in the CRF system,the CP potential measurement and surface examination showed that the CRF debris filters were efficiently protected.
