Chemical behavior of Mo99 formed by the irradiation of uranium oxide with slow neutrons

In this paper we examine the problem of extracting Mo99 from irradiated samples of U3O8 and UO2, fired in vacuum and in a stream of argon from 400 to 1200 °. The relation of the per cent of Mo99 extracted to temperature and time of firing was demonstrated.

The activation energy for removing Mo99 from uranium oxide grains for some sections of the curves was calculated on the basis of the relations obtained between the logarithm of the value of Mo99 extraction and the inverse absolute temperature.
