摘要：
The paper presents modelling and analysis results of contamination of the RBMK-1500 reactor Low Salted Water System (LSWS) components and comparison of the results with other RBMK-1500 water systems at Ignalina NPP Unit 1. These results provide information for radiological characterization, which is an important task of the nuclear installation to be decommissioned. The modelling was performed using a computer code LLWAA-DECOM (Tractebel Energy Engineering, Belgium), taking into consideration LSWS components' characteristics, parameters of the water flowing in circuits, system work regimes, etc. During the modelling, results on activity of LSWS subsystems and components' deposits and nuclide composition of the deposits at the moment of the final shutdown of the reactor, as well as activity decay of the most contaminated PCS components' deposits and dose rates after the final shutdown of the reactor were obtained. Analysis showed that there is significant difference of contamination levels among LSWS components. LSWS activity is lower than Main Circulation Circuit (MCC) and Purification and Cooling System (PCS) subsystems activity. Activity variation for LSWS components is smaller compared to MCC and PCS. Nuclides that mostly contribute to contamination in deposits of LSWS are corrosion nuclides as in MCC and PCS. (C) 2015 Elsevier Ltd. All rights reserved.
