A lithium blanket module (LBM), representative of a fusion reactor blanket module has been fabricated by GA Technologies Inc. via sub contract from Princeton Plasma Physics Lab under the sponsorship of the Electric Power Research Institute. The LBM consists of a cubical array of 92 cylindrical breeder rods, 2.54 cm in diameter. Each rod consists of an ∼59 cm long section of lithium oxide pellets clad in 0.03 cm wall Type 316 stainless steel tube followed by a 20 cm long stainless steel reflector rod. Reusable test rods in the 20 cm diameter central region incorporate activation foils for neutron dosimetry and aluminum clad pellets for tritium dosimetry. The breeder rods are contained in an enclosure structure which has provisions for insertion and removal of test rods and dosimeter wires. Procedures developed for fabrication and assembly of the rods and enclosure structure proved to be satisfactory and reliable and the work was done on schedule and within budget.
