SFCOMPO - Spent Fuel Isotopic Composition Database

Developed by Fuel Cycle Safety Evaluation Laboratory at the JAERI Department of Fuel Cycle Safety Research. Operated by the NEA Nuclear Science Division under the supervision of the Working Party on Nuclear Criticality Safety.

SFCOMPO, the Spent Fuel Isotopic Composition Database, was originally developed at the JAERI Department of Fuel Cycle Safety Research's Fuel Cycle Safety Evaluation Laboratory. SFCOMPO provides isotopic composition data via the internet [Ref 3 and 4]. It archives measured isotopic composition data and the values of their ratios, which are required for the validation of burn-up codes.

Based on discussions at a meeting of the Working Party on Nuclear Criticality Safety (WPNCS) held in December 2001, a system of SFCOMPO for internet dissemination was transferred from JAERI to the NEA Data Bank. The system is now operated by the NEA.

SFCOMPO data covers the following areas:

  1. Reactor Name
  2. Reactor Type
  3. Active Height[mm]
  4. Assembly Name
  5. Assembly Location
  6. Fuel Rod Position
  7. Sampling Position of Fuel Rod[mm]
  8. Initial Enrichment[wt%]
  9. Cooling Time[year]
  10. Laboratory
  11. Burn-up[GWd/MTU]
    • Nd-148 Method
    • Cs-137 Destructive Method
    • Cs-137 Non-destructive Method
    • U, Pu Isotope Based Method
    • Theoretical
  12. PIE Data[kg/MTU initial]
