Aaron Crafthttps://bios.inl.gov/Lists/Researcher/DisplayOverrideForm.aspx?ID=226Aaron Craft Dr. Aaron E. Craft is a research scientist at Idaho National Laboratory, the principal investigator for various projects to develop advanced neutron imaging and other capabilities for post-irradiation examination of nuclear fuel. He has helped develop portable digital x-ray radiography and computed tomography systems for in-field investigation of munitions. Additionally, his expertise with x-ray micro computed tomography has aided multiple programs at INL to develop advanced nuclear fuels and other energy-related materials. He received his doctorate in nuclear science and engineering from Colorado School of Mines, and his bachelor’s and master’s in nuclear engineering from Missouri University of Science and Technology. Outside of work, he enjoys teaching students at local schools about nuclear energy.<div class="ExternalClassE5835D5750594433994B3D88A18C8B37"><p>​Ph.D., Nuclear Science and Engineering - Colorado School of Mines</p><p>M.S., Nuclear Engineering - Missouri S&T</p><p>B.S., Nuclear Engineering - Missouri S&T</p></div><div class="ExternalClassAEB3F9896A254D6CAB30D010845AA0DF"><div><p><span aria-hidden="true"></span>Dr. Craft’s research interests include non-destructive examinations of irradiated nuclear fuels, with an emphasis on x-ray and neutron radiography and tomography techniques. His current projects are focused on developing advanced digital neutron imaging systems capable of imaging highly-radioactive objects with a longer-term goal of making neutron computed tomography a routine technique for post-irradiation examination. Dr. Craft is also leading the formation of a Beamline Examinations for Applied Material Science (BEAMS) Workgroup that will develop x-ray and neutron diffraction and scattering techniques in addition to traditional imaging capabilities. Dr. Craft is also a Nuclear Engineer who enjoys nearly everything nuclear and has contributed to a wide variety of nuclear R&D projects beyond post-irradiation examination.</p></div></div><div class="ExternalClass802C39D958214D639991918929854FA6"><p><span style="font-family:"baskerville old face", serif;font-size:11.5pt;"><font color="#000000">Center for Space Nuclear Research Fellow </font></span></p><p><span style="font-family:"baskerville old face", serif;font-size:11.5pt;">NEUP Fellow</span></p><div class="ExternalClassAE85084A4DE34413A940617B9842486D"><p><span aria-hidden="true"></span><span aria-hidden="true"></span>​American Society for Nondestructive Testing (ASNT)</p><p>American Society for Testing and Materials (ASTM)</p><p>American Nuclear Society (local Chapter President at CSM)</p><p><span aria-hidden="true"></span>ORNL Neutron Beam Sciences Review Committee</p><p>Missouri S&T Nuclear Engineering Department Advising Committee<span aria-hidden="true"></span></p></div></div><div class="ExternalClass0B391E8B3A2C4E3785B54F8532205FF9"><p><strong>Publications (Primary Author) </strong></p><p>Neutron radiography of irradiated nuclear fuel at Idaho National Laboratory, 2015.

Karen Wrighthttps://bios.inl.gov/Lists/Researcher/DisplayOverrideForm.aspx?ID=396Karen Wright Karen Wright is the Instrument Scientist for the EPMA at the Materials and Fuels Complex at Idaho National Laboratory, which she joined in 2000. She set up and operated a JEOL 8900 electron probe microanalyzer for use in studying environmental samples such as radiologically contaminated sediments and asbestiform minerals. More recently, she set up and operated a Cameca SX100R shielded electron probe microanalyzer for the purpose of analyzing irradiated nuclear fuels. In addition to analysis, she has been involved in the construction of transuranic standards and the design of remotely-handled standards and other equipment. Karen holds a master’s degree in geological science. Karen initiated a session for the analysis of irradiated materials at the Microscopy and Microanalysis annual conference and has chaired it. She also served as membership chair for the Microanalysis Society for three years. She recently worked as a visiting scientist at the Institute for Transuranium Elements in Karlsruhe, Germany. In addition to work with microanalysis, Karen has developed radiological decontamination methods, for which she holds two patents and won an R&D100 award.<div class="ExternalClassD2E8D0349A6F4D55BC1E16FAC7C42ABD"><p><strong><span style="color:#000000;font-family:calibri;font-size:11pt;font-style:normal;font-variant:normal;font-weight:400;text-decoration:none;vertical-align:baseline;white-space:pre-wrap;background-color:transparent;">Master of Science in Geological Science, Idaho State University, 1998</span></strong></p></div><div class="ExternalClass95E9F3CC573742E985C36CC097C291FF"><ul><li><div><p>​Electron probe microanalysis of irradiated nuclear fuels to include metal, oxide, and TRISO type fuels</p></div></li><li><p>Development of primary and secondary check standards to increase the accuracy of EPMA analysis of irradiated fuels</p></li><li><p>Developing and testing radiological decontamination methods</p></li></ul></div><div class="ExternalClass604CDCD96F164122889828F03405CA54"><p>Member of the Microanalysis Society</p><p>Member of the European Microanalysis Society</p></div><div class="ExternalClass34DEF07F4250491A97CA30D7C61773B8"><p><strong>Wright, K.E.</strong>, Popa, K., Poeml, P., 2017, Synthesis and characterization of PuPO4--a potential analytical standard for EPMA actinide quantification, accepted for publication in the journal, "IOP Conference Series: Materials Science and Engineering" (in press)</p><p><strong>Wright, K.E.</strong>, Van Rooyen I.J., 2016, Electron Probe Microanalysis of Irradiated and 1600<sup>o</sup>C Safety-Tested AGR-1 TRISO Fuel Particles with Low and High Retained <sup>110m</sup>Ag, 2016 ANS Winter Meeting and Nuclear Technology Expo, Las Vegas, Nevada</p><p><strong>Wright, K.E</strong>., Van Rooyen, I.

Jian Gan, Ph.D.https://bios.inl.gov/Lists/Researcher/DisplayOverrideForm.aspx?ID=737Jian Gan, Ph.D. Dr. Jian Gan is the directorate fellow and department manager of the Advanced Characterization at the Idaho National Laboratory’s Materials and Fuels Complex. He has been dedicated to conducting radiation effects research leading to the development of radiation tolerant materials for 25 years. He has extensive experience using multiple techniques such as light ions, heavy ions, in-situ ion irradiation/microscopy, and neutron irradiation to conduct research focused on the relationships between radiation damage, material microstructure, and material performance on a broad range of reactor structural materials and nuclear fuels. In addition to this effective multidisciplinary approach, Dr. Gan is a recognized international expert in the nanoscale characterization of irradiated fuels and materials using transmission electron microscopy (TEM). Before joining Argonne National Laboratory-West in 2002, he did his post-doc fellowship at Pacific Northwest National Laboratory in 1999-2001. He was an assistant professor (1982-1987) and a lecturer (1987-1990) in Physics Department of Fudan University. He has been working as principle researcher and work package manager for many DOE projects and he is the member of OECD-NEA Expert Group on Innovative Structural Materials. <div class="ExternalClass5C0C0738A86040C88F66DDB9AEEAE5B2"><p>​Ph.D. in Nuclear Engineering, University of Michigan-Ann Arbor, September 1999.<br> M.S. in Nuclear Engineering, University of Michigan-Ann Arbor, August 1994.<br> M.S. in Physics, Central Michigan University, August 1992.<br> B.S. in Physics, Fudan University, China, July 1982.<br><br><br></p></div><div class="ExternalClass2906A56DFB6542B6BA25B3D61C76E0A8"><p>(partial list of over 110 peer-reviewed publications)<br></p><ol><li>Jian Gan; Dennis D.
