Oregon State University TRIGA Reactor (OSTR)

Docket No. 50-243, License No. R-106 In accordance with section 6.7.1 of the OSTRTechnical Specifications, we are hereby submitting the Oregon State University Radiation Center and OSTR Annual Report for the period July 1, 2020 through June 30, 2021.

The Annual Report continues the pattern established over many years by including information about the entire Radiation Center rather than concentrating primarily on the reactor. Because this report addresses a number of different interests, it is rather lengthy, but we have incorporated a short executive summary which highlights the Center's activities and accomplishments over the past year.

I declare under penalty of perjury that the foregoing is true and correct.

The visitors included elementary, middle school, high school , and co ll ege students; relatives and friends; facu lty; current and prospective clients; nati onal laboratory and industrial sc ienti sts and engineers; and state, fede ral and international offici als . The Radiation Center is a significant positive attraction on campus because visitors leave with a good impression of the fac ility and of Oregon State University.

The Radiation Center projects database continues to provide a useful way of tracking the many different aspects of work at the faci lity. The number of projects supported thi s year was 116. Reactor related projects compri sed 77% of all proj ects.

The total research dollars in some way supported by the Radia-tion Center, as reported by our researchers, was $ 16.3 million.

The actua l total is likely hi gher. This year the Radi ation Center provided service to 73 different organi zati ons/in stituti ons, 4 I%

of whi ch were from other states and 41 % of which were from outside the U. S. and Canada. So, whil e the Center's primary mission is loca l, it is also a fac ility with a nati onal and interna-tional cli entele.
