About Prompt Neutron Lifetime Calculation

Dear experts,

I am still on the learning path and I’m currently struggling to get PNL. The same issue is mentioned in another topic but I couldn’t make it work since I’m not very familiar with usage of property objects and it asks for a “states” parameter for pnl() function to operate where I couldn’t figure out what should I feed it with. My intention is to get the PNL value for Jezebel assembly (just as in example file) to test and compare the results but I am not sure which tallies I should be using.

Also in some papers I saw usage of OpenMC(TD) to get Rossi-alpha values, is it an openly accessible version?

I appreciate all the help regarding PNL calculation of Jezebel.

Thanks!
