Abstract

Abstract

It is of great significance to calculate the deposition source term produced by activated corrosion products in HFETR test loop for guiding dose estimation and decommissioning of facilities. In this paper, the test loop is divided into nodes and transport parameters are determined based on the CATE transport mechanism model and computation code. A 9-node transport model of the test loop is established to simulate the generation and distribution of activated corrosion product source terms of the test loop under actual operating conditions, and the results are compared with the actual monitoring data. The research results indicate that the calculation results of the model are consistent with the net effect of the migration direction of activated corrosion products, which proves the reliability of the calculated results. The dose rate error of the source term in the model is within 30% and the calculation results are conservative , which proves the accuracy of the calculated results. This study proves that the multi-node calculation method of the deposition source term in the test loop is applicable under the complex operating conditions of the test reactor and has great engineering application value.
