Systems for separating isotopes from a sample of fission products

A system for separating isotopes from a sample of fission products, the system comprising:

• a container for a sample of fission products;
• a plurality of chromatography columns comprising chromatographic resins of differing isotope selectivity, the container being operatively connectable into a chromatography column of the plurality of chromatography columns;
• a plurality of acid sources, each operatively connectable, via at least one valve of a plurality of valves, into at least one of the chromatography columns of the plurality of chromatography columns;
• a plurality of receptacles, each operatively connectable, via at least one other valve of the plurality of valves, out from at least one of the chromatography columns of the plurality of chromatography columns;
• and
• the plurality of valves being adjustable to transition the system, without physically repositioning the chromatography columns, between:
• a series configuration, wherein a continuous fluid passage is defined through a series of at least some of the chromatography columns to a receptacle of the plurality of receptacles;
• and
• a parallel configuration, wherein a distinct fluid passage is defined, for each respective chromatography column of the chromatography columns:
• from at least one of the acid sources, of the plurality of acid sources, through the respective chromatography column, and
• to a respective additional receptacle, of the plurality of receptacles,
• at least one additional valve, of the plurality of valves, adjustable to transition an inlet of the continuous fluid passage, of the series configuration, between the container and a preconditioning solution source comprising nitric acid.

A system for separating isotopes from a sample of fission products, the system comprising:

• a plurality of chromatography columns reconfigurable, without physically repositioning the chromatography columns, between at least one series configuration and at least one parallel configuration, each chromatography column of the plurality of chromatographic columns containing a different chromatographic resin of a plurality of chromatographic resins comprising:
• a first chromatographic resin conditionable for an isotope selectively specific to zirconium (Zr) isotopes and reconditionable for an isotope selectivity specific to uranium (U) isotopes;
• a second chromatographic resin conditionable for an isotope selectivity specific to at least one lanthanide isotope;
• a third chromatographic resin conditionable for an isotope selectivity specific to molybdenum (Mo) isotopes,
• a fourth chromatographic rein conditionable for an isotope selectivity specific to barium (Ba) isotopes and reconditionable for an isotope selectivity specific to strontium (Sr) isotopes;
• and
• a fifth chromatographic resin conditionable for an isotope selectivity specific to tellurium (Te) isotopes;
• the at least one series configuration defining a continuous fluid passage through at least some of the chromatography columns of the plurality of chromatography columns, and
• the at least one parallel configuration defining, through each respective chromatography column of the plurality of chromatography columns, an individual fluid passage.
