It is found out that self-shielding correction for unresolved resonance data of many nuclei in JENDL-3.3 and ENDF/B-VII.0 is too large around the upper boundary energy of the unresolved resonance region. It is confirmed that this issue can be solved by increasing the upper boundary energy of the unresolved resonance region. In evaluation for unresolved resonance data, the upper boundary energy of the unresolved resonance region should be set to be high enough by considering self-shielding correction.
