Abstract
The Low-Fidelity Covariance Project has developed a complete set of covariance data estimates for all ENDF/B-VII.0 isotopes. Covariance data are provided for elastic scattering, inelastic scattering, (n,2n) reactions, radiative capture and fission (cross section and nubar) over the energy range from 10-5 eV to 20 MeV. Various approximations were utilized depending on the mass of the target, the neutron energy range, and the neutron reaction. The resulting covariance data are not an official part of ENDF/B-VII, but are available for testing in nuclear applications.

Funding
This paper describes the motivation, goals, activities, and status associated with the Low-fidelity Covariance Project (“Low-Fi”). The Low-Fi project was funded in FY07-08 by the United States Department of Energy’s Nuclear Criticality Safety Program (NCSP). The project was a collaboration among Argonne, Brookhaven, Los Alamos, and Oak Ridge National Laboratories. In summary, the Low-Fi project was sponsored by the US DOE Nuclear Criticality Safety Program and involved a collaboration among Argonne, Brookhaven, Los Alamos, and Oak Ridge National Laboratories.
