There are numerous new reactor designs being generated all over the world.

The reactor design had problems because of limited operating temperature constraints.

Just because the reactor design is old doesn't mean it isn't safe.

In fact, I think reactor designs, even old ones, are quite robust.

Also can you imagine how many measurements there are in a reactor design?

In addition, the reactor design has recently been changed to include other safety features.

The basic physics data needed for the reactor design were as yet unavailable.

After problems with nearly every aspect of the reactor design it finally began generating electricity in 1983, 13 years late.

Problems in commercial development are similar to those for any of the existing fusion reactor designs.

Not even the West has mastered the necessary reactor designs.
