The first cycle PUREX raffinate is very radioactive. Thus, two alternate product batches are generated&colon; a raffinate and a strip product. One component of this ISOM site was a unit called the raffinate splitter. The resulting streams will be a loaded organic and a raffinate. With either design, not all of the hydrogen is removed from the product gases (raffinate). Support areas include nitric acid recovery, raffinate treatment and refinery sump. The impurities exit the tower as the raffinate stream for further processing. The digestion, extraction, and raffinate areas included 'hot' and 'cold' sides. Remedial work had been started on the raffinate splitter from February 21, 2005. Currently PUREX raffinate is stored in stainless steel tanks before being converted into glass.
