Nevada National Security Site Site-Directed Research and Development Report (FY 2018 Annual Report)

This report compiles multiple articles describing activities developed and performed under the Site-Directed Research and Development Program for the benefit the Nation during Fiscal Year 2018. Sustained investment and ongoing core innovation are the keys to successful research and development programs. These elements drive the Site-Directed Research and Development (SDRD) Program and provide solutions to some of the most challenging problems our nation and our allies face. Our Nevada enterprise, consisting of both our management and operating entity and our NNSA field office, is aggressively investing in SDRD and injecting innovation through strategic partnerships. Our partnerships with universities, industry, and our sister institutions within the National Nuclear Security Administration (NNSA) build upon our core capabilities and allow us to create innovative solutions to support our mission requirements. In 2018, we raised the investment level of SDRD for only the second time in the history of the program. Nearly at our congressionally authorized limit, SDRD has substantial resources to successfully address numerous issues. Investment is only one part of the equation; innovation is generated through collaborations that bring discovery and provide the “technical differentiation” and the return on investment we seek. This report demonstrates an enduring theme of how partnerships help us drive the best outcomes and provide the maximum impact possible, while using our resources efficiently.

Time-Resolved Phase Transition Kinetics STL-03-15, Year 1 of 1

Presentation describes shock compression experiments performed to measure the dynamic reflectance of light from the surface of tin samples shocked through the β to BCT (body centered tetragonal) solid-solid polymorphic phase transition near 9 GPa, using a technique that extrapolates the low- and high-pressure behavior of reflectance through the mixed phase, allowing researchers to infer the value of the mixed-phase fraction.
