Oregon State University TRIGA Reactor (OSTR) Docket No. 50-243 , License No. R-106 In accordance with section 6.7.1 of the OSTR Technical Specifications, we are hereby submitting the Oregon State University Radiation Center and OSTR Annual Report for the period July 1, 20 16 through June 30, 2017. 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. Executed on: 1o /'3oL7

The material has also been prepared in compliance with Oregon Department of Energy Rule No. 345-30-0 I 0, which requires an annual report of environmental effects due to research reactor operations. Within the scope of Oregon State University's radiation pro-tection program, it is standard operating policy to maintain all releases of radioactivity to the unrestricted environment and all exposures to radiation and radioactive materials at levels which are consistently "as low as reasonably achievable" (A LARA). Environmental Releases The annual reporting requirements in the OSTR Technical Specifications state that the licensee (OSU) sha ll include "a summary of the nature and amount of radioactive effluents released or discharged to the environs beyond the effective control of the licensee, as measured at, or prior to, the point of such release or discharge." The liquid and gaseous effluents released, and the solid waste generated and transferred are discussed briefly below. Data regarding these effluents are also summarized in detail in the designated tables. 16-17 Annual Report

Neutron activation analysis (NAA) stands at the forefront of techniques for the quantitative multi-element analysis of major, minor, trace, and rare elements. The principle involved in NAA Teaching An important responsibility of the Radiation Center and the reactor is to support OSU's academic programs. implementa-tion of this support occurs through direct involvement of the Center's staff and facilities in the teaching programs of various departments and through participation in University research programs. Table lll.2 plus the "Training and lnstuction" sec-tion (see next page) provide detailed information on the use of the Radiation Center and reactor for instruction and training. Research and Service Almost all Radiation Center research and service work is tracked by means of a project database . When a request for facility use is received, a project number is assigned and the project is added to the database. The database includes such information as the project number, data about the person and institution requesting the work, information about students in-volved, a description of the project, Radiation Center resources needed, the Radiation Center project manager, status of indi-vidual runs, billing information, and the funding source. consists of first irradiating a sample with neutrons in a nuclear Table VI.
