License No. R 80, Docket No. 50-157 License No. R 89, Docket No. 50-97 The purpose of this report is to satisfy the reporting 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 (ZPR) (facility license No. R-89) during the period beginning July 1,1996 and ending June 30,1997.

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) neutron radiography demonstrations,

2) use of a low intensity neutron beam for a nuclear measurement

'aboratory course, 3) introduction to neutron activation analysis, and 4) demonstration of reactor operation during steady-state and pulsed modes.

Research programs include,1) trace analysis by neutron activation analysis, 2) research and development of a neutron guide / cold source ,

system, 3) investigation of root soil systems by neutron radiography using high resolution film, and (4) imaging of preferential flow of water through porous media using real time neutron radiography.

> 11. On 2/12/97, the NRC issued Amendment No. 4 which removes the

authority from the license to operate the reactor and authorizes

, possession - only of the reactor.
