Keywords:1F, radiolysis, chemical kinetics, oxygen, hydrogen peroxide, corrosion, database

Reported data on water radiolysis and its effect on corrosion have been surveyed to build a useful database for evaluation of corrosion under the radiation einvironment at 1F. Because of the lack of information on the effect on radiolysis for some chemical species, which could exist in the contaminated water, some radiolysis experiments and simulations have been also carried out to improve the dataset for radiolysis of the contaminated water.
