The covariance data processing and the nuclear data sensitivity and uncertainty analysis of the keff have been carried out for some 1-D benchmark problems by using the ERRORJ/SUSD3D code system. The uncertainties due to the U-233, U-235, U-238, Pu-239, Pu-240, and/or Pu-241 covariance data of JENDL-3.3 have been estimated with the P3-S16 and P3-S4 approximations. The uncertainties amount to 0.53% ~ 1.86% depending on the major actinides of the benchmark cores.
