초록
The objectives of this study are to investigate the effect of the concentration ratios of Ni and Fe ionson crud deposition onto the fuel cladding surface in the simulated primary environments of a pressurizedwater reactor. Crud deposition tests were conducted in the Ni and Fe concentration ratios of 20:20 ppm,39:1 ppm and 1:39 ppm at 325℃ for 14 days. In the case of the same Ni and Fe ion ratio (20:20), nickelferrite with a polyhedral shape was formed. Nickel oxide deposits with a needle shape were formed inthe condition of high Ni to Fe ion ratio (39:1), While polyhedral iron oxide and needle-like nickel oxideformed in the condition of low Ni to Fe ion ratio (1:39). The amount of deposits increased, when Fe oxideswere formed. This indicates that Fe rich oxides stimulated Ni oxide deposition.
