Status of Indian LLCB TBM program and R&D activities

摘要

The Indian LLCB TBM, currently under development, will be tested from the first phase of ITER operation (H-H phase) in one-half of the ITER port no-2. The present LLCB TBM design has been optimized based on the neutronic as well as thermal hydraulic analysis results. LLCB TBM R&D activities are primarily focused on (ⅰ) development of technologies related to various process systems such as Helium, Pb-Li liquid metal and tritium, (ⅱ) development and qualification of blanket materials viz., structural material (IN-RAFMS), tritium breeding materials (Pb-Li, and Li_2TiO_3), (ⅲ) development and qualification of fabrication technologies for TBM system. The present status of LLCB TBM design activities as well as the progress made in major R&D areas is presented in this paper.
