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.
