UNIVERSITY PARK, Pa. — Penn State’s Radiation Science & Engineering Center (RSEC), house to the Breazeale Reactor — the nation’s first licensed and longest constantly working nuclear analysis reactor, is increasing to accommodate an tools donation valued at $9.8 million and to facilitate extra superior neutron beam analysis in addition to the expansion of nuclear engineering at Penn State. With the assist of the College of Engineering, in partnership with the Ken and Mary Alice Lindquist Department of Nuclear Engineering, RSEC will launch a joint initiative as a part of the enlargement to assist novel research in elementary and utilized analysis for Penn State college and college students, business, and collaborative universities and institutes. 

“This is a very exciting time for RSEC, the nuclear engineering department and many other disciplines at Penn State,” stated Kenan Ünlü, director of RSEC and professor of nuclear engineering. “Having access to an operating research reactor is a key strength for Penn State and allows us to harness research and educational opportunities rarely available in the United States.” 

The Breazeale Reactor, which generates an unlimited variety of neutrons per second and permits many various kinds of analysis, was established in 1955 after President Dwight D. Eisenhower launched the “Atoms for Peace” initiative to make use of the comparatively new-found management of the atom to learn human life. 

“The Breazeale Reactor has had several upgrades since its founding,” Ünlü stated. “A significant redesign and installation of five new beam ports was completed in 2018, but we needed a new and expanded neutron beam hall to make full use of the reactor’s capabilities and to establish state-of-the-art neutron beam facilities.”  

One of 5 neutron beam ports might be outfitted with an “extremely” chilly moderator, measuring at a temperature of 20 Kelvin (-423 levels Fahrenheit), that permits simpler transportation of low-energy neutrons to the experimental pattern location by way of neutron guides. This port might be devoted to the Small-Angle Neutron Scattering (SANS) instrument. The SANS instrument was donated by Helmholtz-Zentrum Berlin, Germany, the place it was beforehand put in at a reactor. Ünlü realized of the instrument after giving a chat in 2018 on the International Atomic Energy Agency in Vienna, Austria, when a colleague from Germany talked about tools that was obtainable in Berlin. Ünlü secured the donation, which might be transferred to Penn State in late spring of 2022 when the brand new beam corridor development is accomplished. 

“The Penn State RSEC’s Breazeale reactor will be the only university research reactor with a SANS facility in the United States,” Ünlü stated.

The energy of neutrons across disciplines 

The instrument will allow two analysis choices in a single beam line: steady neutrons and pulsed neutrons. Both approaches permit researchers to measure how neutrons scatter after they work together with quite a lot of pattern supplies, in addition to management which parameters the researchers select to trace when investigating totally different features of the samples.  

“Neutrons are an ideal probe for the investigation of complex materials, including biological materials at the atomic scale,” stated Jean Paul Allain, head of the nuclear engineering division. “SANS is an excellent technique to probe many novel and complex materials systems including soft matter, glasses, biomimetic structural proteins, microemulsions, flexible electronics and many more systems.”  

To oversee the design, administration and group of the Penn State SANS facility, Allain and Ünlü convened main neutron scientists to ascertain the primary Penn State Neutron Science Advisory Council, chaired by Robert Dimeo, director of the National Institute of Standards and Technology Center for Neutron Research. Dimeo can be a Penn State alumnus, who earned his grasp of science in electrical engineering in 1994 and his doctorate in physics in 1999. 

“The SANS facility has broad applicability across a wide swath of disciplines, and the facility at Penn State provides opportunities not just for research impact, but also for educating and training students,” Dimeo stated. “When I was a graduate student, I would’ve loved to have had access to something like this right on campus.” 

According to Dimeo, no less than half of all beamtime requests — the reservations to make use of neutron science amenities for numerous analysis functions — across the nation are rejected attributable to lack of sources. 

“This facility provides opportunities to expand research capabilities across Penn State and to help support operations for the scientific community across the United States,” Dimeo stated.

The analysis capabilities go beyond nuclear science and engineering, in keeping with Dimeo, Allain and Ünlü. Eberly College of Science and the College of Earth and Mineral Sciences, in addition to the Huck Institutes of Life Sciences and the Materials Research Institute all have college desperate to see what the SANS instrument may reveal about their material of alternative, Allain stated. 

“The new SANS equipment will provide the opportunity to study the detailed atomic structure of glasses and other materials, providing key insights into the relationships between atomic structure and the macroscale properties of a wide range of materials,” stated John C. Mauro, professor and affiliate head for graduate training within the Department of Materials Science and Engineering within the College of Earth and Mineral Science. “More broadly, SANS will provide a platform for cross-disciplinary collaboration among nuclear engineering, materials science and engineering, physics, chemistry and other departments at Penn State.” 

Premier neutron science vacation spot 

The deliberate enlargement additionally demonstrates an in depth collaboration and deep dedication between RSEC and the Ken and Mary Alice Lindquist Department of Nuclear Engineering, which is experiencing an unprecedented progress of college and college students since its institution in the summertime of 2019, in keeping with Allain. The enlargement will embody workplace areas for RSEC workers, nuclear engineering college, graduate college students and visiting scientists who will collaborate with Penn State college on the brand new SANS instrument and the Breazeale Reactor. 

“The education and research mission of the nuclear engineering department and RSEC have enjoyed a strategic partnership for many decades in the College of Engineering,” Allain stated. “Strengthening already close ties, the college is making a significant investment in both the department of nuclear engineering and RSEC.”

The 10,000-square-foot enlargement is a $9.5 million funding for the College of Engineering, excluding the worth of the donated tools. According to Allain, it’s a worthwhile endeavor that can reap advantages for the University and beyond. He famous that Penn State’s enlargement of nuclear science and engineering may even accommodate business stakeholders for collaborative analysis tasks, in addition to function a key attraction in recruiting prime college and college students.

A groundbreaking occasion is deliberate for Oct. 22, the place management from the 2 models will ceremoniously break first floor and start development. It serves as a symbolic demonstration of not solely constructing towards a way forward for scientific development, but in addition highlighting the collaborative nature of Penn State, in keeping with Justin Schwartz, Harold and Inge Marcus Dean within the College of Engineering.

“The partnership between Drs. Ünlü and Allain to not only organize the physical upgrades but to also initiate truly transformative research and curriculum efforts is a stellar example of the interdisciplinary work that positions the Penn State as a leader in nuclear research,” Schwartz stated. “Penn State is becoming one of the nation’s premier neutron science destinations — a vibrant hub of students and researchers engaged in multidisciplinary education and research.”
