Reference:

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, 1983, and ending June 30, 1984.

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 low intensity neutron -beam for a nuclear. measurement laboratory course, 3) introduction to neutron activation analysis, and 4) demonstration of reactor operation during steady-stat.c and. pulsed modes.

Research programs included,1) trace 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.
