Nuclear data for fusion analysis

Output

For example

Heat deposition

Neutronics simulation

OpenMC neutron transport

Nuclear data

For example

ENDF B 8.1 library

Nuclear data underpins every neutronics simulation, from neutron photon transport to activation studies.

Where is nuclear data used

Activation

Decay heat

 

Delayed responses

Tritium breeding ration

Neutron / photon heating

Instantaneous Dose

 

Prompt responses

Decay data

half lives

decay modes

energy spectra of decay product

Q values of decay

emitted neutron photon spectra

Body text

Q values for every reaction

fission yields

product yields

isotope masses

branching ratios

gamma emission (discrete, cotinuum ....)

delayed neutron emission

Body text

Angular distributions

neutrons and photons in outgoing channel (can be correlated)

thermal scattering laws

resonance parameters (for resolved resonance region)

 

atomic relaxation data (after photoelectric absorption m k 

  • electron shell structure
  • fluorescence yields
  • Auger yields
  • x-ray transition probabilities
  • binding energies

Cross sections

total, elastic, inelastic, capture, fission,
(n,2n), .... hundreds of energy dependant reactions

coherent scattering, incoherent scattering, pair production ....

for several temperatures
