License No. R-80, Docket No. 50-157 License No. R-89, Docket No. 50-97 The purpose of this letter is to satisfy the requirements of Section 50.59 of 10CFR,'Part 50, in respect to activities carried out on the Cornell TRIGA reactor (facility license No. R-80) and the Cornell Zero Power Reactor-(facility license _No. R-89) during the period beginning July 1, 1982 and ending June 30, 1983.
TRIGA - License No. R-80
- 1. Operating Experience During the period ' reported herein the TRIGA reactor was used primarily for the purpose of teaching and research and to a small extent, instrument _ test and calibration.
Teaching programs included, 1) control rod calibration, 2) use of a low intensity neutron beam for a nuclear measurement laboratory course, 3) introduction to neutron' activation analysis, and 4) demonstration of reactor operation during steady-state and pulsed modes.
Research programs included.I 1) t' race. analysis 'by neutron acti-vation analysis, and.2) use of a' neutron beam for the investigation-of fissioning isomers.
Instrument test and calibration included performance measure-ments of neutron sensitive detectors, utilizing the central thimble, thermal column, and the annular space in the reflector.
