Event timings compared to station data and previous studies.
| | Event | Station data (s) | [18] (s) | This work (s) |
| | Loss of class IV power | 0 | 0 | 0 | | Turbine trip | 0 | 0 | 0 | | Emergency stop valve (ESV) close | No data | 0.28 | 0.28 | | Stepback on turbine trip | 0.5 | 0.5 | 0.5 | | CSDV open | 0.8 | 0.8 | 0.8 | | ASDV open | 1.0 | 13.6 | 13.5 | | SDS1 low flow trip | 2.9 | 3.3 | 3.41 | | Liquid relief valve (LRV) open | 3.5 | 4.2 | Not actuated | | SDS2 low flow trip | 11.6 | N/A | N/A |
