Abstract

Disclosed is a solid lithium-lead blanket for a fusion reactor, where a solid lithium-lead alloy is adopted as a neutron multiplier and a tritium breeder, and is placed in a form of a unitary or binary pebble bed inside a structural skeleton composed of structural materials; and nuclear thermal deposition in the solid lithium-lead alloy generated due to an interaction between the solid lithium-lead alloy and a fusion neutron is moved out by a coolant. A proportion of lead atoms in the solid lithium-lead alloy is low, so that, under normal operations and accident conditions of the blanket, the solid lithium-lead alloy always remains in a solid state without melting, and tritium can be brought out of the reactor by purge gas flowing through the pebble bed to allow tritium self-sufficiency. The blanket of the present disclosure does not require beryllium to meet the requirements of tritium breeding.
