Item | Test ID | Test year | Test condition | Major thermal-hydraulic phenomena |
Station blackout (SBO) | TR-LF-16 | 2015 | SBO transient with loss of primary coolant with AM measures | Steam discharge through SG RVs, and single- and two-phase natural circulation |
Loss of reactor shutdown functions | TR-LF-13 | 2007 | LOFW transient without scram with delayed actuation of AFW system | Two-phase natural circulation |
Loss of ECCS water injection functions | SB-CL-41 | 2011 | LOCA with 8-in. break at cold leg with AM measures under totally failed HPI system | Critical flow at break, steam discharge through SG RVs, loop seal clearing, core boil-off, and steam condensation on ACC water |
Loss of heat removal functions from secondary cooling water system | TR-LF-07 | 1992 | Total LOFW transient with primary feed-and-bleed operation | Coolant discharge through PZR PORV, two-phase flow in PZR, two-phase stratified flow in hot leg, and steam condensation on ACC water |
Loss of ECCS recirculation functions | None | Expected; steam binding, core liquid level reduction, and core reflooding |
