Random ENDF files from other libraries

Last update: 9 February 2021

Random nuclear data files can be useful to repeat identical simulations with different nuclear data. This is the whole idea behind TMC (Total Monte Carlo). For more information, please read our paper. You can find such random files in the TENDL subdirectories for each isotope (obtained from random variations of model parameters).

But another solution is also possible: generate random libraries based on the covariance files (so-called MF32, MF33, or MF34). This is an approximation compared to the original TMC method, but it is also a very convenient solution to propagate uncertainties based on other libraries than TENDL.

Thanks to the SANDY tool developed by L. Fiorito (SCK.MOL), one can now easily produce random files based on JEFF-3.3, ENDF/B-VIII, or any other library (including TENDL of course). For details on SANDY, you can read this paper. If you want to access and run yourself SANDY, please look at this github page, and at these notes.

But for those of you who want to rely on us and directly use random files produced by SANDY, here they are by groups of 300 random files. They were simply produced with this command:.

sandy $file --samples 300 --njoy njoy-2016.47
