Most nuclear survival guides assume the only radioactive contamination you need to worry about comes from fission fragments from the bombs themselves. How realistic is this? There isn’t anything stopping the enemy from hitting a nuke plant with ground bursts for maximum contamination. Each power plant also has hundred to thousands of tons of spent nuclear fuel ON SITE, so you don’t just need to worry about the fuel in the reactor but all the storage containers as well, this will all get released into the atmosphere to create a disaster literally 1000’s of times worse than Chernobyl. Each warhead only has about 50-100 pounds of material to generate fallout from, but hitting a single nuclear power plant will release many orders of magnitude more fallout. Spending 2 weeks in a sealed basement isn’t going to do jack shit to protect you in a scenario like this, the whole US will be inhabitable for thousands of years most likely.
