The reactor is supposed to be pulsed, so 1ms might be fine. Skipping the heat cycle is possible if they achieve their goal of using aneutronic fuel. With D-T fusion (the easiest) the output energy is 80% neutrons, so you're stuck with heat. With aneutronic, you mostly get fast-moving charged particles.
