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 Independent Data

MF=4 to 99

Temperature Independent Neutron Data: ENDF MF=4 to 99

Data are Included for ALL 557 ENDF/B-VIII.0 Evaluations (MF=4 to 99)

Download and Uncompress MF4to99 ONCE (use with ALL temperatures)

Temperature Dependent Data
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
