ANALYSIS OF Mo99 PRODUCTION IRRADIATING 20 %U TARGETS

ABSTRACT

At present time, CNEA is producing about 800 Ci of Mo99 per week irradiating 90% enriched uranium - aluminum alloy plate targets in the RA3 reactor, a 5 Mw. MTR type one. In order to change to 20% enriched Uranium, and to increase the production to about 3000 Ci per week, some configurations were studied with rod and plate geometry with uranium (20% enriched) - aluminum targets.

The first case was the irradiation of a plate target element in the normal reactor configuration. Results showed a good efficiency, but both reactivity value and power density were too high.

An element with rods was also analized, but results showed a poor efficiency, too much aluminum involved in the process, although a low reactivity and an acceptable rod power density.

Finally, a solution consisting of plate elements with a Zircalloy clading was adopted, which has shown not only a good efficiency, but it is also acceptable from the viewpoint of safety, heat transference criteria and feasibility.
