October 3, 2014. Presentation Overview. PFRC will produce at least 100 times fewer neutrons than a D-T burning reactor. Neutron radiation is still damaging, but PFRC will require much less shielding than a D-T Tokomak (less than a meter compared to several meters). Neutrons (Basic Concepts). Neutrons (Basic Concepts).
