Standalone Containment Analysis of Four Phébus Tests with the ASTEC and the MELCOR Codes

Table 1

Main characteristics of the different Phébus tests with a solid fuel bundle.

Test	Fuel	Fuel Degradation	Primary Circuit	Containment
FPT-0	Fresh Fuel 1 Ag–In–Cd rod 9 days pre- irradiation	Melt Progression and FP release in steam-rich environment	FP chemistry and deposits in non-condensing steam generator	Aerosol deposition and iodine radiochemistry at pH5
FPT-1	BR3 fuel ≈ 23 GWd/tU 1 Ag–In–Cd rod Re-irradiation	As FPT-0 with irradiated fuel	As FPT-0	As FPT-0
FPT-2	As FPT-1	As FPT-1 under steam poor conditions	As FPT-1 with effect of boric acid	pH9 evaporating sump
FPT-3	As FPT-1 with B4C instead of Ag–In–Cd	As FPT-2	As FPT-0	pH5 evaporating sump recombiner coupons
