The last series of the EC funded project included additional five SBLOCA experiments. VTT Energy and LTKK ran the experiments in August and September 1997. Based on the experiences from the previous series, the new experiments were performed in the third and final series of the EC funded programme.

In this series the CMT position was moved to a 1 m higher elevation than in previous experiments. The purpose was to increase the driving head of the passive safety system. The result was about 10% higher flow rate during the recirculation phase of the system. Also, a very small break size was used to investigate if the driving force could disappear due to filling of the CMT with warm water. As a result, the experiment showed this phenomenon.
