Thermal-Hydraulic Analysis of PDS-XADS Spallation Target
摘要
Abstract
The thermal-hydraulic analysis of PDS-XADS spallation target for 80 MW reactor core power was studied. PDS-XADS is a small scale experimental accelerator driven sub-critical system (ADS). The analysis presented in this paper was based on lead bismuth eutectic (LBE) cooled XADS type experimental reactors, which are the designs of the European experimental PDS-XADS project. The spallation target is a very important component of ADS because it is responsible to keep the reactor power at the required level by spallation reactions. A high rate of neutron production by spallation reaction creates the problem of decay heat cooling. LBE flow is properly cooled, but the window is not properly cooled because of the stagnation point in the pole of the window. It would be very difficult to keep the window temperature below the design limit, which is an important design limit challenge. Thermal-hydraulic analysis of LBE spallation target was carried out by using ANSYS CFX 11.0. The detailed CFD analysis, which reveals thermal and hydraulic conditions in the window and spallation region, was carried out for different spallation target designs. Finally, the spallation target design limit was used to choose the best design.关键词
