Overpressure Predictions by the MEM and the Baker-Strehlow-Tang Blast Curves for the SRI H2 Explosion Test in the Open Space

A safety distance between a Very High Temperature Gas-Cooled Reactor (VHTR) and a hydrogen production facility is usually determined based on the maximum overpressure under the assumption of a H2 explosion accident. If the overpressure due to the H2 explosion is predicted by a correlation, the determination of the safety distance may be performed easily. As for the prediction method of the overpressure, the Multi-Energy Method (MEM) and the Baker-Strehlow-Tang blast curves (B-S-T blast curves) are widely used because they can cover from a deflagration to a detonation. However, they were mainly validated for a hydrocarbon gas explosion. Thus, a validation work should be performed against the H2 explosion test data to apply the MEM and B-S-T curves for the H2 explosion accident
