Thermal Response Of The Ifmif Lithium Loop At Beam Trip

The thermal response of liquid lithium (Li) at beam trip has been studied by modifying a computer code. This is a part of the design activity of the International Fusion Materials Irradiation Facility (IFMIF), which will provide high flux, high energy neutron irradiation fields for testing: and development of fusion materials by deuteron-li reaction in the target. By the accelerator system, two deuteron beams are focused onto a liquid Li target. An existing computer code for reactor transient response has been modified to deal with Li, and the transient analysis has been performed for thermal response of IFMIF primary Li loop in cases of one and two beams trips.
