WebThe primary containment system usually consists of a large metal and/or concrete structure (often cylindrical or bulb shaped) that contains the reactor vessel. In most reactors it also contains the radioactively contaminated systems. WebThe subpile area connects to the concrete basemat which also has some concrete loss. This is the main structural support for the reactor pedestal. With the damaged concrete, you have reduced seismic resistance. You could have a collapse of the reactor pedestal. This can potentially damage or destroy parts of the reactor building and containment.
