Mechanical Mockup of IFE

Mass Production and Target

Irina Aleksandrova, Elena Koresheva, Evgeniy Koshelev,

Target production and its delivery into the reaction chamber of high repetition rate facilities are the most challenging issues in inertial fusion energy (IFE) research. At the Lebedev Physical Institute of Russian Academy of Sciences (LPI), efforts are underway on creation of the mechanical mockup of IFE reactor (MM-IFE) for developing the reactor-scale technologies applicable to mass production of IFE targets and their delivery with a repeatable rate into the chamber of IFE reactor. In this chapter, we discuss the current status and further trends of developments in the area of advanced target technologies underlying the research and development program on

Keywords: inertial fusion energy, free-standing target systems, mass production,

The goal of IFE research is development of high-precision and mass production technologies for fueling a commercial power plant at the rate of 10 Hz [1]. The conventional approach to solid layering based on the beta-layering method [2] is unable to ensure the IFE requirements, as it (a) works with targets fixed on a suspension (no repetition rate operation), (b) has a long layering time (more than 24 h that leads to a large tritium inventory), (c) shows the grain boundaries dynamic under thermal and mechanical loads in time between the moment just after target preparation and the laser shot, which results in roughening of the layer surface and may lead to implosion instabilities, and (d) has a high production cost

The beta-layering method can form a spherical fuel layer in a uniform thermal environment; however, it is inefficient in preventing local defects. Therefore, the
