The following email was received from @luca-fiorito-11.
NJOY sets by default the number of subsections ni=1 for MF34.
This is not specified in the ENDF-6 format manual, which, on the contrary, allows using more than 1 subsection also for MF34.
Line 1942 of error.f90 in NJOY2016.42
if (mfcov.eq.34) then
nc=0
ni=1
endif
For Fe56 in JEFF-33, the covariance between P1/P1 is given in 3 subsections (ni=3)…therefore NJOY fails to run.
By commenting out the lines reported above, NJOY completes the calculation.
Still, I think unit tests should be run to see if the change does not disrupt the NJOY regular behaviour.
