SUMMARY

OF OPERATIONS

1. INSTRUCTIONAL USE Nuclear Engineering (NE) 231, "Survey of Nuclear Engineering" was offered in the spring semester with an enrollment of 30 students. The course is designed for freshmen students interested in nuclear engineering and consists of three lecture modules surveying fission, fusion and radiation science technologies. The fission module concludes with a reactor tour.

Two sections of NE 427 were offered in the fall and spring semesters with a total enrollment of 48 students. Several NE 427 experiments use materials that are activated in the reactor. One experiment entitled "Radiation Survey" requires that students make measurements of radiation levels in and around the reactor laboratory.

Two sections of NE 428 were offered in the fall and spring semester with a total enrollment of 41 students. Three experiments in NE 428 require exclusive use of the reactor.

These experiments ("Critical Experiment", "Control Element Calibration", and "Pulsing") required a total of 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> of exclusive reactor use. Other NE 428 laboratory sessions use material that has been irradiated in the reactor ("Fast Neutron Flux Measurements by Threshold Foil Techniques" and "Resonance Absorption").

A new course entitled "Detection and Remediation of Radionuclides in the Environment" was developed in collaboration with Civil and Environmental Engineering.

The cross listed course, NE 602/CEE 629, was offered in the spring of 2013 with 16 students participating. More details about this new course can be found in section A.4 of this report below.

4. OTHER MAJOR EDUCATIONAL, RESEARCH, & OPERATIONAL ACTIVITIES In December 2012 the facility conducted reactor demonstrations "offered at a distance" with Spring Harbor Middle School in Madison, WI. Over 95 children participated in a lecture and demonstration that was broadcast over the internet. Adobe Connect Pro software was utilized to connect the Spring Harbor Middle School with the UW Nuclear Reactor Lab. The reactor demonstration included a supercritical power excursion and demonstration of the prompt negative fuel temperature coefficient of reactivity that ended with a reactor scram to show the shutdown characteristics of a nuclear reactor.

In May 2013 the facility conducted a nuclear energy workshop "offered at a distance" with the State Engineering University of Armenia in Yerevan, Armenia. Approximately 24 students participated in 3 laboratory sessions over a 3 day period. Again, Adobe Connect Pro software was utilized to connect Yerevan with the UW Nuclear Reactor Lab. The reactor modules included an approach to critical, control element calibration and pulsing behavior of TRIGA reactors.

This program was supported by the U.S. Department of Energy (DOE) via the International Nuclear Safety Program (INSP) and the Safety Analysis Capability (SAC) program managed by Argonne National Laboratory.

The remote connectivity capability described above was funded through a NRC Educational Curriculum Development Grant, entitled "Remote Nuclear Reactor Measurements Laboratory: Development of innovative web-based nuclear engineering measurement modules to be offered at a distance".

UWNR ANNUAL REPORT- Fiscal Year 2012-2013 Page.9 of 15 In the spring of 2013 a collaborative effort between the UW Nuclear Reactor and the UW Department of Civil and Environmental Engineering developed a new course in the detection and remediation of radionuclides in the environment. Sixteen students from both curricula participated in the course. The course focused on the fundamental and practical concepts in nuclear engineering and environmental engineering to educate students from both disciplines so that they can communicate with each other.

The course included hands-on laboratory experiences in both disciplines. The course development was funded through a NRC Educational Curriculum Development Grant.

5. CHANGES IN PERSONNEL, FACILITY AND PROCEDURES Any changes reportable under 10 CFR 50.59 are indicated in section E of this report.

SUMMARY

OF RADIATION EXPOSURE OF PERSONNEL (01/01/12 - 12/31/12)

The personnel radiation monitoring program at the University of Wisconsin for the past calendar year used LandauerLuxel brand monitors for whole body and extremity exposure. No personnel received any significant radiation exposure for the above period. The highest annual doses recorded were 20 mrem to the whole body and 50 mrem to the extremities.

The highest dose received by a member of the public visiting the reactor lab was 0.67 mrem, as measured by Siemens brand Electronic Personal Dosimeters.

Monthly radiation surveys continue to demonstrate acceptable radiation dose rates within the reactor laboratory and no contamination.
