Conceptal Design And Numerical Analysis On A High Temperature Helium Experiment Loop, HTHEL

The tritium breeding blanket concept is a very important experiment platform in ITER,which will achieve tritium self-sufficency and extract high-grade heat that will be translated into electricity. At the same time, it will offer reliable statistics in order to build blanket in the DEMO reactor. ITER, as an important experimental platform for developing fusion energy, will be used to conduct some relevant technical experiments by the participant countries. In this instance, China submitted the Design Description Document for the Chinese Helium Cooled Solid Breeder(CH HCSB)Test Blanket Module to TBWG in 2004. Now, all the relevant design and research about the HC-SB TBM is in progress. The first test blanket module for testing electromagnetic will launch into the experiment as soon as ITER running. Constructing a high temperature helium experimental loop is essential to insure the TBM's design credibility and operational safety.On the base of domestic and abroad helium experimental loop design and running experiences, the conceptual of high temperature helium loop was designed, in which the main loop system, pressure control system, water cooled system, helium pure system and key components was presented.Recuperator is an important component in the loop. It adopts finned heat exchanger according to the characteristic of the gas-to-gas heat exchanger, the thermal design and numeric analysis is also carried out.The professional software is used to simulate and analyze the pipe's stress and force condition at the key part of the pipe and the junction of the pipe and circulator. According to the simulated results, the pipe design is reasonable; the condition of the stress and influence to circulator is allowable.The operation and security of the loop is proved in the thesis, the main research is summarized and the suggestion for the next work in the last part is proposed.The design, calculation and analysis in this thesis is valuable for the future further detailed design and practical engineering design.
