We have performed benchmark tests for JENDL-4.0 released last year in shielding and fusion neutronics fields. Now we analyze OKTAVIAN TOF experiments (CF, Si, Ti, Cr, Mn, Co, Cu, As, Se, Zr, Nb, Mo, W) with JENDL-4.0 in order to validate JENDL-4.0. For comparison we also do with the older version JENDL-3.3 and other recent nuclear data libraries (ENDF/B-VII.0, JEFF-3.11). The Monte Carlo code MCNP-4C was used for these analyses. We adopted the official ACE files for JENDL-4.0, JENDL-3.3, JEFF-3.1 and ENDF/B-VII.0. As a result, the following results are obtained through comparison between calculation and measured results. (1) As, Se, W: Calculation results with JENDL-4.0 agree with the measured ones better than those with JENDL-3.3. (2) CF, Si, Co, Mn, Cu, Ti, Mo, Zr: Calculation results with JENDL-4.0 are almost the same as those with JENDL-3.3. (3) Cr, Nb: Calculation results with JENDL-4.0 are partially better and partially worse than those with JENDL-3.3.
