Dosimetry User's Perspective on Covariance Needs

The dosimetry community has a critical need for covariance matrices to characterize the uncertainty in the input nuclear data used in a range of applications. This need is growing more acute as the nuclear regulatory community increases the rigor with which dosimetry statements must be made and supported. This paper presents and prioritizes a set of needs that reflect the application of neutron dosimetry to the research reactor and commercial nuclear power industry.
