A chemical cleaning program was developed to remove iron and copper fouling in the feedwater system of Arkansas Nuclear One (ANO) power company. The fouling caused an increase in pressure drop across the steam generator and an increase in steam generator water level. The cleaning process is divided into four phases: process qualification, system design, cleaning, and waste disposal. Phase one demonstrates the reliability of the program through pre-test evaluation, preliminary solvent investigation, corrosion testing, and a qualification test on a model boiler. Phase Two system design is based on the conceptual process description and process flow diagram developed by UNC. The scope of work in Phase Three includes construction and operation of cleaning system, provision of all equipment materials and personnel, solvent chemical analysis, and restoration of plant to precleaning condition. Solvent monitoring is used to determine when the iron and/or copper sludge removal cycle is completed. In Phase Four a generic design provides the capability to process chemical and radioactive wastes separately. APandL will use the Hanford low-level radwaste burial ground for its waste.
