[8] It is expected to enter the 'care and maintenance' stage of decommissioning in 2027. Subsequently, Unit B22 has been intermittently shut down for up to several months at a time. It seems that deposition on the north shore of the headland does not keep pace with erosion, although the power stations are about 1 km to the west of that shore. Problems with the construction of the pressure vessel liner had distorted it, so that the boilers, which were to fit in an annular space between the reactor and the pressure vessel, could not be installed, and the liner had to be partially dismantled and rebuilt. "New technology, which is seeing smaller reactor types developed, could suit Dungeness very well." No need to register, buy now!
