Popis:	Radiation effects on the uranium retention property of degraded n-dodecane by acidic radiolysis in the Purex process were studied. The absorbed dose of n-dodecane varied from 24.04 to 2403.69 kGy (5 to 500 Wh/dm3) . When the absorbed dose exceeded 48.07 kGy (10 Wh/dm3), the uranium (UO22+) was retained in degraded n-dodecane even without TBP as extractant. An empirical correlation of the uranium retention was also derived. This correlation is a very effective one because it can especially be used for the prediction of the amount of retained uranium in the degraded n-dodecane. Data obtained through this work should be useful for the process design under solvent degradation conditions in nuclear fuel processing facilities especially in reused solvent.
