Description of need

According to Venu Varma at Oak Ridge National Laboratory, the neutron irradiation in a Nuclear fusion reactor can be as high as 1E5 Sv/hr and 1E5 W/m3 heat.

A comparison with Nuclear fission is helpful:

  • In a PWR, all the fuel elements are inside water, so water does a good amount of shielding. You can go to do maintenance inside the reactor.
  • In fusion, we don’t have this luxury. Will need to do remote maintenance, i.e. remove and store large, highly radioactive components.

Utility connections are also a challenge, especially:

  • the vacuum vessel seal
  • the coolant seal
  • the blanket seal
