Operation of the Aircraft Reactor Experiment

Distribution and behaviour of 233Pa in 2LiF–BeF2 molten salt

“…Consequently, MSR is extremely suitable for nuclear application of thorium resources, and thorium-based molten salt reactor has become a hot spot in the development of MSR. 4 The world's rst MSR, aircra reactor experiment (ARE) with 2.5 MW power, was built by Oak Ridge National Laboratory (ORNL) at USA in 1954, 5 and the construction of a 10 MWt molten-salt reactor experiment (MSRE) was started in 1961. Aer reached criticality in 1966, the MSRE has been operated with 235 U and 233 U as fuel successively and separately for 4 years.…”

Evaluation of Power Fluidic Pumping Technology for Molten Salt Reactor Applications

“…Fluidic technology could be used as a high reliability metering pump to add or remove precise amounts of fuel to operating MSRs as needed to compensate for burnup or power level shifts. In the Aircraft Reactor Experiment (ARE), the fuel salt 235 U concentration was increased 8.8% over the course of operationsfrom 0.383 g/cc to 0.416 g/cc-as operational power was increased [53], demonstrating the potential to alter fuel loading to provide power level shifts.…”

Study on Kinetic Characteristics of Krypton and Xenon radioactive source term in molten salt reactor

“…The concept of Molten Salt Reactor (MSR) originated from the Aircraft Reactor Experiment (ARE) [1,2] Molten Salt Reactor Experiment (MSRE) [3,4], Molten Salt Breeding Reactor (MSBR) constructed or designed by Oak Ridge National Laboratory (ORNL) in the 1950s and 1970s [5,6], Denatured Molten Salt Reactor (DMSR) [7] and other experimental reactors.In 2011, the Thoriumbased Molten Salt Reactor Nuclear Energy System (TMSR) project was set up by Chinese Academy of Sciences. A molten salt reactor with 2 MW thermal power(Hereinafter referred to as 2MW MSR) is planned to be built in 2020 [8].…”
