Among the very extensive engineering works undertaken during the Fukushima programme, new systems were installed to further ensure proper cooling of the reactor core in any potential emergency situation. In addition, a new emergency control room (PCS3), designed to withstand the extreme conditions described above, was built above a new heavy water handling building; see Fig. 11.7. The ILL’s skyline was also altered by the new chimney, strengthened to prevent any potential damage to the ILL reactor containment building.
The STR programme required an exceptional effort on the part of the ILL’s staff while the additional expense, totalling about 30 M€, resulted in severe financial difficulties. However,
