Thorium is a possible nuclear fuel to achieve the sustainable development of energy. The molten salt reactor (MSR) has great potential and advantages in realizing efficient utilization thorium resources. However, there are still many challenging technologies be developed, such as graphite lifetime problem, complex online processing salt. Therefore, actual deployment timelines thorium-based MSR unpredictable. In this research, Thorium-based Molten Salt Fast Energy Amplifier (TMSFEA), which...
A compact photoneutron source (PNS), based on an electron linac was designed and constructed to provide required nuclear data for the design of Thorium Molten Salt Reactor (TMSR). Many local shielding are built reduce background neutron γ rays, making location time flight (TOF) detector be fixed at 6.2 m place. Under existing layout, some physical parameters very difficult get by experiments, while can obtained Monte Carlo simulation method. However, deep penetration problem rays transport...
A numerical simulation program for the dynamic distribution of krypton and xenon with flow on-line removal function was established primary loop system molten salt reactor(MSR) Based on Mathe-matica7.0.The results static burnup compared ORIGEN-S program, deviation is less than 10%, which in good agreement.The characteristics were analyzed under regionalization online model.The show that,the model underestimates total 135 Xe activity about 6.61% system, underestimated by 1.46%.Under maximum...
Conventional neutron targets in accelerator driven subcritical system (ADS) are based on the design using heavy metal like lead and lead-bismuth eutectic (LBE), which generally needs a separated loop for target cooling. In thorium-based molten salt fast energy amplifier, an integrated is conceived that proton beam directly placed chloride/fluoride core without cooling consideration of productivity liquid fuel bombarded with proton. The physical analysis spallation presented, including yield,...
The existing thermal neutron molten salt reactor design has a complicated online processing system that many technical difficulties. A thorium-based fast energy amplifier (TMSFEA) driven by proton accelerator can operate stably for nearly 40 years at rated power of 300 MW without processing. In order to simplify the core structure TMSFEA, is based on hollow and moderator-free cylindrical geometry. in serves as both fuel spallation target. this paper, previous TMSFEA physics design,...
The neutronic properties of Molten Salt Reactor are different from that traditional solid-fuel reactors due to its nuclear fuel particularity. Based upon MCNP code, the influence size and shape salt channel on neutron physics MSR cell was studied systematically in this work. results show infinite multiplication factors increases first then decreases with change graphite under condition given volume fraction. In case same FVF average chord length, when length is relatively small, k values...
