Newsletters and Reports

Stewardship Science Today Newsletters Heading link

The Office of Research, Development, Test, and Evaluation publishes the Stewardship Science Today  newsletter on a quarterly basis. The newsletter highlights current research carried out by groups in the DOE/NNSA laboratories in a wide variety disciplines in the support of science-based stockpile stewardship.

Volume 3, Number 3 features research being conducted at Los Alamos National Laboratory and Lawrence Livermore National Laboratory to improve the safety of explosives. This issue also introduces you to the first two alumni of the DOE/NNSA Laboratory Residency Graduate Fellowship (LRGF) program and the new classes of the Stewardship Science Graduate Fellowship and LRGF programs.

Volume 3, Number 4 features an article about the record-breaking shot that occurred at the National Ignition Facility in August and important research being conducted at Texas A&M University’s Center of Research Excellence on Dynamically Deformed Solids. Be sure to note the upcoming events listed on the Calendar, particularly the early January deadlines for submitting applications to the DOE/NNSA Stewardship Science Graduate Fellowship and Computational Science Graduate Fellowship programs.

Volume 4, Number 1 highlights the winners of Best Poster Awards from the recent Stewardship Science Academic Programs Symposium, and provides an outline of SNL’s multi-platform study of Ga2O3, along with a description of a new digital holography diagnostic for shock compression experiments, and a brief update on studies of helium bubble dynamics in aging plutonium.

Volume 4, Number 2 is the first to be published by the Defense Programs Office of Strategic Partnerships, which now manages the NNSA Stewardship Science Academic Programs. Featured in this issue are an update from the Predictive Science Academic Alliance Program III, an outline of new opportunities for collaborative work on Sandia’s Z Machine, and new results from Lawrence Livermore National Laboratory showing that new scintillating nanoguide fiber blocks provide superior performance as compared to legacy fiber blocks for neutron imaging.

Stewardship Science Academic Programs Annual Heading link

The Stewardship Science Academic Programs Annual is published yearly by the Office of Research, Development, Test and Evaluation and outlines recent developments in the SSAP Centers, features student and alumni profiles, and reports on new developments in stewardship science research taking place in the NNSA Laboratories.

SSAP Annual 2021  contains profiles of CDAC alumna Sakun Duwal (p. 20), now at Sandia National Laboratories, and CDAC graduate student Samantha Couper (p. 24), along with two research briefs on diamond encapsulated silicon fibers and the multi-technique synchrotron x-ray and infrared spectroscopic study of the complex silicate material jarosite at high pressure (p. 13).

SSAP Annual 2022 features an article (p. 17) describing the the combination of theory and experiment in the UIUC and Utah groups.  At UIUC, Brian Blankenau and Tianyu Su are carrying out experiments at HPCAT in support of their first-principles calculations in the Complex Materials and Phase Transition Dynamics Thrusts. At Utah, Samantha Couper has used finite element modeling using the ALE3D method to illuminate her deformation and texture development experiments on MgO + MgSiO3 mixtures, a part of the Plasticity, Strength and Deformation Thrust.
