Overview

The Covariance Committee (CovCom) has the responsibility for addressing the topic of covariances relevant to evaluations that are to be included in the U.S. ENDF/B Library. While the actual generation of covariances is the responsibility of individual evaluators who produce these evaluations for ENDF/B, this committee maintains oversight and provides technical assistance and advice in the following areas:

• Encourage the development of methodologies for generating reasonable and reliable covariance information.
• Establish quality criteria for the covariances included in the ENDF/B library.
• Review covariance files submitted for inclusion in the ENDF/B library.
• Advise other committees of CSEWG on matters related to covariances.
• Maintain contact with the nuclear applications community regarding their requirements for nuclear data uncertainties.
• Provide sources of information concerning covariances.

For further details concerning the mission and methods of operation of this committee please refer to the CovCom Charter.
