Perhaps Dr. dr Vicente is talking about ITER, but surely not a real fusion reactor.
Here's something talking about an actual fusion reactor:
"While the radioactivity level per kilogram of waste would be much smaller than for fission-reactor wastes, the volume and mass of wastes would be many times larger."
and
"To reduce the radiation exposure of plant workers, biological shielding is needed even when the reactor is not operating. In the intensely radioactive environment, remote handling equipment and robots would be required for all maintenance work on reactor components as well as for their replacement because of radiation damage, particle erosion, or melting."
