JEFF-3.3 Evaluated Data: fission product yields data

The JEFF-3.3 library provides independent and cumulative fission product yield data for a wide range of actinides undergoing neutron-induced and spontaneous fission. These evaluations support reactor physics, fuel cycle analysis, decay heat calculations, and radiological assessments by supplying consistent yield distributions that underpin many applications in nuclear technology and safety. The JEFF-3.3 yields represent an update over earlier releases, incorporating revised evaluations and benchmark testing to improve reliability across energy ranges and fissioning systems.
