Nuclear power plants require human actions throughout their lifecycle from design,
construction, operation, and decommissioning. However, for advanced reactors (eg …

Abstract If the Total Loss of Feedwater (TLFW) accident occurs in a VVER reactor, the
primary side Feed & Bleed (F&B) recovery strategy prevents core damage by reducing the …

After the Fukushima accident, passive safety features have been highlighted to prevent
severe accidents. Since passive safety features are newly adopted in a nuclear power plant …

Combined accidents are considered as very rare events and therefore are not usually
considered in deterministic or probabilistic safety analyses. Yet, despite being rare, it is …

In the wake of the Fukushima accident, several applications of new safety features have
been highlighted to prevent severe accidents. As the feasibility of the newly applied systems …

In emergency operating procedures (EOPs) of largepressurized water reactor, feed-and-
bleed (F&B) operation and reactor coolant system (RCS) rapid cooldown are considered as …

Although a feed and bleed (F&B) operation is an important emergency task having a
significant effect on the risk of a pressurized water reactor–type nuclear power plant, there is …

In the case of combined accident, the accident sequence is very complicated, so it is not
easy to identify the accident sequence and perform the proper actions. In order to decide …
