Covariance matrices were calculated for the $sup 238$U, $sup 241$Pu, and $sup 239$Pu fission cross sections and for the $sub 23$$sub 8$ $sup 240$Pu, $sup 241$Pu, and $sup 239$Pu capture cross sections. A computer program was written which uses the evaluated ENDF/B data files and the measured or evaluated (from other evaluations) cross sections for the calculation of the uncertainty files. An effort has been made to make the output of the program consistent with the ENDF/B error files format. A user's manual for the present code and references utilized in the covariance matrix calculations are given. (auth)
