Nuclear data measurements, analysis and evaluation at the Oak Ridge National Laboratory in support of nuclear criticality safety

This paper describes the activities in nuclear data measurement, nuclear data evaluation, and nuclear data testing at the Oak Ridge National Laboratory in support of the US Department of Energy Nuclear Criticality Safety Program. Data measurement's activities are performed at the Oak Ridge Electron Linear Accelerator (ORELA); data evaluations are done with the computer code SAMMY; and cross section processing is performed by the AMPX and/or NJOY code systems.
