Neutron Flux differences in LMFBR vs Thermals

This image shows the major differences in Thermal and LMFBR enutron energy with the neutron flux as the y axis and energy as X. As neutron flux increases, thermal experiences a major slope downwards while in the .001 eV to 10 eV range, LMFBR doesn't even play a role - it is at a very high neutron flux and energy that LMFBR is effective

Back to Thermal ReactorThermal Reactor Back to Fast Neutron ReactorFast Neutron ReactorA Fast Neutron Reactor is a specific type of reactor that different from a Thermal Reactor-- it is not very common because unlike a thermal reactor that uses neutron to sustain the chain reaction, a FNR has no neutron moderation and less primary coolant due to an excess of fast neutrons * the capture to fission ratio is lower is fast reactors * high number of neutron produced per one fission * Neutron Flux has differences too The following image shows the neutron flux differences 400 Neutron F
