Abstract

Abstract

In order to establish the time and spatial distribution model of boron and provide support for the experiment of boron transport and heat transfer within the Chalk River Unidentified Deposit (CRUD) depositions, the reproduction method of CRUD depositions was studied based on anodic oxidation method. With reference to the morphology data of the real CRUD depositions in the PWRs, the effective control of the pore size can be realized by adjusting the ammonium fluoride concentration, water concentration, oxidation voltage and oxidation time of the electrochemical system. Characterization analysis shows that the reproduced CRUD deposition samples can fully cover the range of morphological parameters of the real CRUD depositions. Therefore, the reproduction method established in this study can be used for the reproduction of CRUD deposition samples.
