Repetition rate target and fusion chamber systems for HiPER

Abstract

We review development in the repetition-rate target area systems and technologies within the Work Package 15 of the HiPER Preparatory Phase project. The activities carried out in 2009-2010 have been involving analysis of solutions and baseline design of major elements of the repetition-rated fusion chamber, analysis of prospective injector technologies, numerical modelling of target survival during acceleration phase and during flight in the environment of fusion chamber, analysis of options of remote handling, systems of mitigation of fusion debris, and others. The suggested solutions assume operation at the repetition rate of 10 Hz and fusion yield between 20 and 100 MJ. Shock ignition is assumed as the baseline ignition scenario, although some technologies are applicable in the fast ignition; a number of the technologies identified are exploitable as well in the indirect drive. The operation of the HiPER repetition-rate chamber will contribute to technology development for the Demonstration Reactor HiPER facility.

Thermo-fluid dynamics and corrosion analysis of a self cooled lead lithium blanket for the HiPER reactor

“…25 690 1.98 , 9 0 .875 0.125 (5) where ν is the corrosion rate expressed in μm yr −1 , T is the local temperature in K, d is the channel width (expressed in cm; d = 8 and 70 cm in the inner and outer channels, respectively), and V is the average value of the velocity magnitude of the fluid (in m s −1 ) on an area of the cross-section of the channel with an azimuthal width of the order of the mean azimuthal size of the computational mesh cells on the whole cross section. According to [19,40], using equation ( 5) is consistent with the assumption that the corrosion rate is controlled by the diffusion of the metallic elements of the blanket walls dissolved into the flowing Pb-Li.…”

“…The European High Power Laser Energy Research (HiPER) facility [1], dedicated to demonstrating laser driven fusion as a future energy source, is divided into two phases: HiPER engineering and HiPER reactor. This division foresees HiPER reactor conceived to be the power producing extension of the technologies developed during the HiPER engineering phase [2][3][4][5][6]. It would be a 150 × MJ/shot 10 Hz inertial fusion energy (IFE) reactor based on direct drive ignition [7] and the dry wall concept [8,9].…”

Silica final lens performance in laser fusion facilities: HiPER and LIFE

“…The radiation nature and fluxes in laser fusion depend on the type of target. In this work we follow the studies of direct and indirect targets carried out in the frame of the ARIES project 3 . Thus, we use the ARIES direct drive target with a yield of 154 MJ to study the irradiation conditions of the final lenses in the HiPER demo power plant.…”

“…The HiPER project [1][2][3] is at the end of the preparatory phase (phase 2). The next step (phase 3) will take place over the next seven years to carry out appropriate R&D activities that eventually will lead to the construction of a demonstration (demo) power plant (phase 4).…”
