Exercises

Exercise 1

Generate 200 perturbed ACE files from the JEFF-3.3 evaluation for U-235 in file u235.jeff33. Use 20 CPUs and post-process each file at a temperature of 300 K. Perturb both cross sections and fission yields.

python -m sandy.sampling  u235.jeff33  --samples 200 --processes 20 --temperatures 300  --acer

Exercise 2

Generate 5 perturbed copies of the ENDF-6 file pu239.endf80. Use 1 CPU and do not produce the ACE files, but only perturbed ENDF-6 and PENDF files. Perturb both cross sections and fission yields.

python -m sandy.sampling  pu239.endfb80  --samples 5
