AGN 201 Reactor- Fission Plate y

Gn This letter is written at your request concerning the unaccounted for fipion '

plate for the Georgia Tech dismantled AGN 201 training reactor. g Following the dismantling of our.AGN 201 reactor, a special nuclear material (SNM) inventory was made.on December 20, 1984 At the time and up

.until recently it was thought that all of the enriched uranium was accounted for properly. Subsequent testing showed this.not to be true. After searching rather thoroughly a 168.22 gm element weight and 29.49.6m isotope weight fission plate has not been found.

~

A review of past records definitely indicate a degree of confusion over this fission plate. Past Georgia Tech license operators.say that we nave never had a fission plate with this reactor.. My feeling is the same now that we . ave studied the situation.in more. detail.

Over the years since 1967, when Georgia Tech acquired ~ the AGN 201 reactor from the University of Dayton, our DOE /NRC form 742 inventory reports have shown a total of 3498 gm element weight' and 695 gm isotope weight. As late as July '1987 we mistook a blank poly disk (poorly stamped 473.5 grams) for the unaccounted for fission plate (supposedly stamped 483.0 grams). Please refer to the attached breakdown of the . enriched uranium.

Should you need additional information on this SNM inventory deficiency, I will be happy to try and provide it for you. A Nuclear Material Transaction Report (Form 741) has been submitted to Oak Ridge concerning this deficiency.

Sincerely, k -

Robert M. Boyd RMB/jlr
