An improved process for removing oxygen from an aqueous medium used in a steam generating system, the aqueous medium having hydrazine added thereto, wherein hydrazine-containing aqueous medium condensate formed in a condenser is exposed to ultraviolet light in the condenser hotwell, prior to being recycled to the steam generator. The exposure to ultraviolet light is for a period of time sufficient to effect removal of the dissolved oxygen by the hydrazine without the need to add chemical additives or catalysts to the system.
