For the design and optimization of reactors a precise knowledge of the microscopic neutron data is needed. For this purpose, new evaluations for a number of important fast reactor materials have been performed at this laboratory. Reevaluations of ²³⁸U and ²³⁹Pu are discussed. To check the quality of the presently evaluated data in reactor physics calculations, their effect on k _eff for a large variety of critical assemblies is studied. Calculation shows that with the evaluated data for ²³⁵U, ²³⁸U, ²³⁹Pu, ²⁴⁰Pu, ²⁴¹Pu and ²⁴²Pu the value of k _eff for a large number of critical assemblies can be reasonably well reproduced without any adjustment of the data.
