Development of Innovative Nuclear Reactor Technology to Produce Protected Plutonium with High Proliferation Resistance: Requirements and Validation of Nuclear Data

The Protected Plutonium Production (P3) project has been initiated. The first stage of this project (P3‐A) is based on the idea of protecting plutonium by 238Pu isotope generated from 237Np doped in the fresh uranium fuel. The present status of nuclear data relevant to the P3‐concept reactor design is surveyed and data requirement is presented.
