CONCLUSIONS
Advanced reactors create new challenges in TH codes development & validation |
Neither right boundary conditions are available to study PS behaviour nor correct energy sources to the containment are obtained |
Integrated FUMO is the result of efforts aimed at investigating advanced
reactor TH
basing on a realistic "plant approach"
Mainly intended for prediction of
containment phenomena but results show
that indications on overall plant behaviour can be obtained
Integrated code assessment on
experimental data is presently not feasible

Some aspects involving an effect of AP600 & SBWR containment phenomena on the PS accident evolution highlighted: |
Gravity & Containment pressure driven coolant injection | |
passive residual heat removal systems | |
long term cooling features |
Intrinsic limit in pressure reduction linked to the absence of active systems |
