Pebble bed is another type nuclear energy. This design of the reactor is for more fuel efficiency and lower risks. Instead of using water, pebble bed uses gases such as helium, nitrogen, and CO2. This doesn't require the steam management process that other nuclear techniques need. This also increases thermal output by 30 - 50%. Pebble bed is used is Germany, China, and Southern Africa. The safety feature of pebble bed is that it produces 1000 times less radioactive gas into our atmosphere. Pebble bed is a greener version of nuclear power.
