A mechanism of ferrite formation on BWR fuel surface

  • 1. Hitachi Ltd., Tokyo (Japan)

Description

Feed water iron concentration control has been applied in Japanese BWR plants to reduce Co activity concentration in rector water. Co activity was fixed on fuel cladding surface by ferrite formation from iron crud and Ni2+ as reactor water impurities. But the mechanism of ferrite formation on fuel cladding surface has been nuclear. A ferrite formation experiment was performed to clarify the mechanism on a simulated fuel cladding surface under simulated reactor water conditions that accompany boiling and flow. The results indicated that ferrite formation on the fuel cladding surface and character of the fuel crud are related to the surface condition of fuel cladding and iron species in the reactor water.
