ITER is also not planning to capture the neutrons. It is only planned to produce more thermal energy than the total amount of electrical energy put in.

DEMO will be plants built independently by several nations following the research from a successful ITER. They will be the first time that any attempt is made to actually convert the fusion products into electricity. There are currently no concrete plans for any DEMO plant - those are contingent upon ITER's success.

If everything goes to plan, the first model DEMO plant would begin operation in 2051. So, as I said, we are a long way away from producing even 1W of usable electrical power from fusion.
