SUMMARY:NE Seminar: "An Examination of Nuclear Forensics at PNNL: A Multidi
 sciplinary Examination of Nuclear Data"
DESCRIPTION:Abstract\nIn an era of increasing global instability\, the pros
 pect of finding nuclear devices or materials outside of regulatory control
  is an ever-increasing concern\, while the threat of a nuclear detonation 
 becomes a sobering reality that we may face. In this threat filled landsca
 pe\, nuclear forensics emerges as means to decipher fundamental questions:
  what is it? Where did it come from? How did it get there?\n\nWithin nucle
 ar forensics\, there are two domains\, framed in the context of a nuclear 
 device\, pre-detonation and post-detonation. Pacific Northwest National La
 boratory (PNNL) is one a few laboratories tasked with stewarding US capabi
 lities that investigate materials in both domains.\n\nIn this talk\, the b
 roader topic of nuclear forensics will be discussed as it pertains to PNNL
 \, however further focus will be applied to the post-detonation domain. We
  will highlight the efforts of a highly diverse multidisciplinary team exa
 mining a pursuit to improve the nuclear data\, a foundational underpinning
  of nuclear forensics\, of several high impact isotopes. These nuclear dat
 a examinations explore fission products yields\, single isotope decay sche
 mes\, both radiochemically separated and unseparated with a variety of rad
 iation spectroscopic techniques including advanced coincidence systems.\nB
 io\nNic Uhnak\, Ph.D.\nStaff Scientist and Team Lead\nPacific Northwest Na
 tional Laboratory\nDr. Nic Uhnak is a staff scientist at Pacific Northwes
 t National Laboratory. He attended undergraduate at Boise State University
 \, studying Chemistry\, where he discovered a love for radiochemistry. He 
 furthered his education at Washington State University\, where he studied 
 inorganic chemistry\, which focused on trivalent f element separations for
  nuclear fuel reprocessing.\n\nDr. Uhnak joined PNNL as a NTNFC (National 
 Technical Nuclear Forensics Center) Postdoctoral Fellow shortly after his 
 defense. During his 8-year tenure at PNNL\, he has focused on chemical sep
 arations associated with nuclear forensics\, currently leading efforts to 
 create ML/AI enabled predictive separations models\, as well leads the PNN
 L efforts to improve fundamental nuclear data\, as well as a leading membe
 r of the operational nuclear forensics team.
