The nuclear characteristics of the thermal blanket and blanket-shield designs are analyzed to provide a basis for optimizing the blanket design of D-D fusion reactors. The thermal blanket is devised to yield high energy deposition in a compact blanket through the use of neutron multiplier and energy converter with 1/v neutron absorption cross section. The blanket-shield design, on the other hand, aims at providing acceptably good shielding characteristics to protect the superconducting magnet by incorporating shielding substances within the blanket itself.<BR>The results of calculation reveal that the thermal blanket design provides only modest energy deposition in the blanket despite its use of beryllium, which is limited in availability. In contrast, the blanket-shield concept is found to offer attractive possibilities in terms of nuclear characteristics, and the results of this analysis point toward the blanket-shield concept as the logical choice for D-D fusion reactor blankets.
