Aspects of secondary reactions in single- and
double-stage targets (ST7)

• Needs
• Good spallation codes
• ? validation with data (thin target)
• Residues (particles to be done in T4)
• Associated with a transport code
• validation with data (thick target) (ISOL data)

Aspects of secondary reactions in single- and
double-stage targets (ST7)

• Status at CEA-Saclay
• Development of INCL4 (with Liège Univ.)
• Numerous comparisons of INCL4/ABLA with data
  (Hindas project)
• Implementation of INCL4 and ABLA in MCNPX
• Coupling of MCNPX with CINDER (evolution code
  from LANL)
