The hydrogen propellant (or water in the case of a terrestrial reactor) is seeded with tungsten nanoparticles which absorb UV like nobodies business, eliminating the need for the high pressure hydrogen. The boundary layer is actually neon, which is injected to form an irrotational vortex (the opposite of a tornado) that pushes everything to the center at high pressures.
