Sandia and the Kansas City National Security Campus (KCNSC) have identified, researched, and selected a new conformal coating for the W88 Alt 370 program. A conformal coating is required in the application to provide environmental protection to the sensitive electronics. The new conformal coating replaces a previously selected coating that had demonstrated significant off-gassing of volatile species and poor accelerated-aging performance. The new coating does not suffer from poor aging behavior and exceeds requirements for the program. 1800, 2300, and KCNSC were the lead organizations.
The Program Office led a multidisciplinary team that evaluated nine different stockpile scenarios for the Nuclear Posture Review development. The analysis showed the ability of each site to deliver, what risks would be introduced, what assumptions would need to be made, how each site would be impacted, and how surveillance and dismantlement would be affected. The analysis and the results were compiled in three weeks to inform the discussions at HQ. The work used tools developed by the Enterprise Modeling and Analysis Consortium to quickly perform this task. (2100)
The Product Realization Information Management & Exchange (PRIME) project created an application that consolidated, modernized, and optimized the authorization (EA Web), storage and retrieval (Image Management System-IMS), and exchange (NSE Hub) of engineering authorizations (EAs) and product definition. It was successfully deployed in December 2016 across the NSE. PRIME has supported a significant increase in EA releases — from 792 per month in 2016 to 1,024 per month thus far, largely in support of product realization activities for the B61-12 and W88 ALT programs.

SEP provides program and supply chain management to ensure requirements and expectations for nuclear weapon production deliverables are met. (2000, 5000, 10000)
What happens when a detonation hits a corner? Modelers/ designers need to understand to optimize explosive performance. Techniques to see “inside” explosives during detonation, like flash X-ray, have limited resolution. Researchers in 02554 developed techniques to deposit and detonate thin-films of explosives to study performance at small scales. Using conventional ultra-high-speed imaging, the first optical images of corner turning behavior were presented at the 2017 American Physical Society Shock Meeting in the paper “Detonation Corner Turning in Vapor-Deposited Explosives Using the Micromushroom Test.” (2000, 1000, LDRD)
