摘要:
The paper discusses the problem of fouling and corrosion in the Service Water System of a nuclear reactor employing an open recirculating cooling system. Field and laboratory experiments were carried out using carbon steel as test material. The studies included corrosion rate measurements, corrosion product characterisation (using XRD, EDAX and IRAS), and the effects of addition of biocide (chlorine) and corrosion inhibitor (polyphosphates) on the bacterial population of the cooling water. The fouling films which developed on metal and glass coupons as well as debris collected from within the cooling system were chemically characterised. The results indicated the prevalence of microbiologically induced corrosion (MIC) within the system. The findings are discussed in the light of the information available on MIC of cooling water systems.
