Strontium fluoride flowsheet development studies for the waste packaging program

PDF Version Also Available for Download.

Description

It was demonstrated that the modified version of the Martin flowsheet can produce SrF/sub 2/ of acceptable quality using a simulated feed of the same composition as the anticipated packaging plant feed. By careful control of operating conditions, strontium losses in the process can be reduced to an acceptable level. Using a nonrepresentative radioactive feed (which contained impurities not present in the simulated feed) high strontium losses were encountered in the feed purification step, although the purification obtained was excellent. The other steps in the process presented no difficulties. Additional tests of the feed purification step will be necessary when ... continued below

Description

It was demonstrated that the modified version of the Martin flowsheet can produce SrF/sub 2/ of acceptable quality using a simulated feed of the same composition as the anticipated packaging plant feed. By careful control of operating conditions, strontium losses in the process can be reduced to an acceptable level. Using a nonrepresentative radioactive feed (which contained impurities not present in the simulated feed) high strontium losses were encountered in the feed purification step, although the purification obtained was excellent. The other steps in the process presented no difficulties. Additional tests of the feed purification step will be necessary when a representative feed is available to ensure that strontium losses can be reduced to an acceptable level. The proposed flowsheet differs from the Martin flowsheet in that a feed purification step is used in the proposed process. All the remaining steps in the process are essentially identical and the data and recommendations reported in the Martin publications appear applicable to the proposed process. Based on the results of this study (and including data published by the Martin Company), a detailed flowsheet with recommended operating conditions is given.
