Generation of 238U Covariance Matrices by Using the Integral Data Assimilation Technique of the CONRAD Code

Generation of 238U Covariance Matrices by Using the Integral Data Assimilation Technique of the CONRAD Code

A new IAEA Coordinated Research Project (CRP) aims to test, validate and improve the IRDF library. Among the isotopes of interest, the modelisation of the 238U capture and fission cross sections represents a challenging task. A new description of the 238U neutrons induced reactions in the fast energ...
