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 iespect 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,- 1997 and end.ing June 30,1998.
IBIGA-LICENSE NO. R-80
- 1. Operating Experience l' During the period reported herein the TRIGA reactor was used
.primarily for the purpose of teaching and research and, to some extent,.. instrument test and calibration.
1 Teaching programs included,1) neutron radiography. demonstrations,
' 2) use of a low intensity neutron beam for a nuclear measurement c laboratory course, 3) introduction to neutron activation analysis, and?4) demonstration of reactor operation during steady-state and
,p m pulsed modes.
%. Research programs include,1) trace analysis by neutron activation
,'E analysh, 2) research and development of a neutron guide / cold source
'sy. stem, 3); investigation of root soil systems by neutron radiography u3 lng high resolution film, and (4) Imaging of m .grubsis they moved through soit using real time neutron
.? ; radiography,

. Instrument test and calibration included performance measurements of neutron sensitive detectors, utilizing the central thimble, Hat reflector face, and the annular space in the reflector.
- 2. Chanaes in Facility Design None
- 3. Changes in Procedures Standard Operating Procedures for the TRIGA reactor were changed to improve clarity and conform to a new format designed to facilitate checkout and calibration of the safety and control instrumentation. All changes were reviewed and approved by the Ward Reactor Laboratory Safety Committee.
- 4. Sitrveillance Tests and Inspections All parameters and systems undergoing surveillance tests and inspections are determining to be within the specified limits.
- 5. Power Generation 93 Megawatt hours
- 6. Emergency Shutdowns None-
- 7. Unintentional Scrams None
- 8. Maior Maintenance None r.
