Isotopic signatures from high-energy electron bremsstrahlung are key observables for a number of nuclear security applications, and these applications depend on specific nuclear data. The Photonuclear Reactions for Isotopic Signature Measurements (PRISM) accelerator is a state-of-the-art S-band electron linac at LLNL accelerator complex which will be used to acquire such data. In addition, a pulsed photo-fission neutron source will be generated using the same x-ray beam for neutron time-of-flight scattering experiments. Experimental capabilities and recent progress towards these experiments will be discussed. A methodology for constraining nuclear data with integral scattering experiments will also be discussed.
