According to Research Program “Advanced Nuclear Fission Energy-ADS Transmutation System”, pool-type reactor CLEAR-I with lead-bismuth natural circulation will be built before 2020 to verify neutronics, thermal-hydraulics and safety characteristics and to test integration technology for ADS system. A sub-channel analysis of the core was performed to locate the hottest fuel assembly and obtain coolant flow distribution. Maximum fuel and cladding temperatures and coolant velocity are below design constraints.
