Primary Physics
Design of nuclear weapon primaries and performance and reliability assessments
Mission
To design nuclear weapon primaries and assess their performance, reliability, and surety.
What we do
The Primary Physics and Design Group, XTD-PRI, designs nuclear weapon primaries and assesses their performance and reliability.
XTD-PRI provides intellectual leadership toward improved predictive understanding of primaries, develops primary design and certification methods, and plays a leadership role in the integration of weapons-directed theoretical, experimental and modeling activities throughout the Laboratory.
More broadly, XTD-PRI also applies its technical capabilities to enhance the entire portfolio of work of the X Theoretical Design (XTD) division.
