A first wall structure for use in a fusion device surrounds the plasma region and includes a base wall which is substantially continuous. The base wall has an inner surface which faces the plasma region and an outer surface which faces the first wall coolant. The inner surface has a plurality of recesses. The wall structure also includes a number of inserts corresponding in number to the recesses with each insert being received in a respective recess and extending inwardly beyond the inner base wall surface. The inserts are made of material having a substantially greater heat flux capability than the material from which the base wall is formed. A method of forming a composite first wall structure for use in a fusion device, is also disclosed.
