This study was started in 1982 as the part of BEFAST programme. In this year (1984), periodical measurements of the concentrations of micro-element (Fe,Ni,Cr)in the pool water continuously perform and the results were statistically compared with the results of 1983. It seems that nosignifi

As a part of the IAEA coordinated programme on BEFAST, behavior of spent fuel assemblies during extended storage, corrosion of pool components has been investigated. In this study the concentrations of micro-elements of corrosion products (Fe, Cr, Ni) in pool water have been periodically measured and the evaluation of corrosion has been made from the results of analysis. The concentration of micro-elements of corrosion products (Fe, Cr, Ni) was almost constant during this study. Corrosion rate was estimated to be only a little as compared with the pool lining in thickness of 3 mm (the side) or 4 mm (the base).
