Instrument Description


The production element chopper (PEC) resides in the argon cell at the Fuel Conditioning Facility. The PEC is designed to chop Experimental Breeder Reactor-II (EBR-II) driver fuel elements into small segments (typically .25” up to a maximum length of approximately 1”). The element segments are produced via a programmable logic controller (PLC)-controlled electromechanical press capable of producing 30 tons of force. The elements are typically automatically fed into the press via a servo-controlled linear slide feed mechanism. The feed mechanism houses a cassette able to hold a maximum of five elements. Elements are chopped directly into an anode basket to support electrorefining operations.

Applications


Size reducing irradiated fuel elements for further processing.


Specifications


  • Ability to process five elements simultaneously

  • Fuel diameters that range from 0.174 - .500” have been sheared in the PEC

  • Designed for chopping EBR-II fuel elements (Mk-IA, Mk-II, Mk-IIA, Mk-IIB, Mk-IIC, Mk-IICS, Mk-IIS, Mk-III, Mk-IV)

  • Ability to obtain sample segments at any location of the fuel element

  • Manual or automatic sequencing capabilities
