the same time, then we really should be very worried. and these things are the breach and the confinement chamber of a nuclear power plant. so, every nuclear reactor that contains a core, nuclear core, reactor core, is protected by a very robust reinforced concrete confinement chamber that is designed to withstand an explosion internally of the reactor core that might release this radioactivity. it's designed to contain that radioactivity inside but it is also designed to withstand the outside impact of a certain intensity. of course, the staged shelling by missiles and artillery might compromise that confinement chamber. um, but the -- the -- the breach of the confinement chamber itself might not necessarily result in a nuclear accident. what -- what is critical for a safe operation of a nuclear
