I do not like this particular design because they are not continuously removing fission products. This means the drain tank must be able to dissipate large amounts of heat from decaying fission products in the event of an emergency shutdown. Much better to use a fuel cycle where you are continuously removing the fission products. Also requires active cooling rather than just a melt plug for emergency shut down. This leaves you open to Fukashima type failures.
