Anticipated transient without scram (ATWS) are considered as events which might produce a severe accident in a boiling water reactor (BWR). It has been selected the most unfavourable of the different scenarios that could lead to an ATWS accident: an inadvertent closure of the main steam isolation valves (MSIVs).
To mitigate this accident, a borated water solution is injected. This action is an alternative way to shutdown the reactor quickly and effectively. This event has been analyzed using the TRAC-BF1 computer program.
