Abstract

Comprehensive investigations have revealed that the so called AP-CITROX (alkaline permanganate, citric acid + oxalic acid) technology is not an adequate method for the chemical decontamination of any reactor equipment having large stainless steel surfaces (e.g. steam generators), and has a detrimental effect on the morphology, chemical composition and mobility of the oxide layers grown on eg. heat exchanger tube surface. As a consequence of the lack of the appropriate decontamination method, an R&D project to develop a technology for decontamination and surface treatment of the inner surfaces of the steam generators at Paks NPP has been initiated. In this paper, we present some selected findings on the corrosion and surface chemical effects of the APCITROX technology as well as on the fundamental issues of the technology development. The second and third parts of the three-part series are scheduled to highlight some results obtained in the course of solution chemical calculations and laboratorial analysis of the efficiency of the technology to be developed.
