POINT2021: IAEA-NDS-237 report
ENDF/B-VIII.0 includes 557 Evaluations
First each entire evaluation is included after ENDF2C
(ENDF2C makes evaluations FORTRAN, C and C++ Compatible)
Next each evaluation is divided into 2 Parts
1) Temperature Dependent Data - ENDF MF = 1 to 3
2) Temperature Independent Data - ENDF MF = 4 to 99
To use EACH evaluation you MUST
1) download &
uncompress the 2 parts
2) Merge the 2 parts
together to define a complete
evaluation

Temperature
Dependent Neutron data: MF=1 to 3
Data at Each
Temperature are Included for ALL 557 ENDF/B-VIII.0 Evaluations
(MF=1 to 3).
Data at 12 Different
Temperatures (13 entries: 0.1eV = 1200 K) are
Included.
Download and
Uncompress
EACH
Temperature you are interested in.
For use in applications temperature DEPENDENT (MF=1 to 3)
and
INDEPENDENT Data (MF=4
to 99) MUST be MERGED
