2018 | AFC ACCOMPLISHMENTS 119 Figure 4. Temperature and pressure histories for the in-cell LOCA test NA#1 through full integral test sequence, including water quench at 800°C. In-cell re-fabrication of a high burnup commercial fuel segment into an integral LOCA test train and successful testing in the Severe Accident Test Station demonstrate the readiness to evaluate accident tolerant fuel (ATF) concepts subject to design basis accident (DBA) and beyond design basis accident (BDBA) scenarios.
