Publikováno v: Journal of Nuclear Science and Technology. :1-10

The Pt coating (Pt-C) process has been developed to lower the recontamination by 60Co which was incorporated in oxides on piping surface after chemical decontamination. In order to determine the suppression mechanism of 60Co deposition by Pt-C, it is

Investigation of cobalt buildup behavior and suppression by zinc injection on stainless steel under HWC conditions using simultaneous continuous measurements of corrosion and cobalt buildup

Autor: Makoto Nagase, Ohashi Toshimasa, Tsuyoshi Ito, Hideyuki Hosokawa, Motohiro Aizawa

Publikováno v: Journal of Nuclear Science and Technology. :1-8

In boiling water reactor (BWR) plants, cobalt-60 (60Co) is the main source of radiation exposure, and it builds up on oxide films of structural materials. The 60Co buildup is caused by its incorporation into the oxide films. In the BWR plants using h
