Deb, there is typically no "Ka-BOOM" associated with a biological attack, therefore making your Nuc Pwr Plant irrelevent. Even a NUC attack on Knoxville probably wouldn't make the Pwr plant explode. (Sparky could answer that better than I)
Let's try this again....
Bad guys aren't going to hit Oak Ridge by biological attack. The only way to hit Y-12 would be by air or an insider. Y-12 is not a nuclear power plant. Y-12 is a huge compound, covering miles, it is where the Manhattan Project was. K-25 is also over there and it is currently being dismantled....and has been in the process for several years and will continue for several years more.
I
know there is not a KA-BOOM with a biological attack.
The TVA system is totally separate from the OR facilities....though the OR facilities have had a very detrimental effect on the TVA system due to all the contaminates that OR has put into the waters and water table for 40-50 years.
Obviously they no longer do, but the damage was done years and years ago. There is so much nuclear contaminated materials buried in the OR area...that no one even knows where it's all buried. Which is why so much of the wildlife over there is "altered" - extra eyes, missing legs, etc....and why only those desperate for food will eat the fish caught in the waters downstream from OR.
Back on a biological attack....it has been a major concern around here since 9/11, that it would be so easy for terrorists to contaminate the TVA system or to blow up one of the dams. Obviously the dams are well patrolled but it is impossible guard the shorelines against terrorists.
Although...those TVA guys are very good at determining if you've put in an illegal dock or you cut down any trees on your property that TVA has an easement. TVA has easements along every bit of shoreline in the TVA system. While a landowner may "own" the land several feet - sometimes 100's of feet - out into the water, they are not allowed to build within a specified footage of the "TVA high water line". In most cases, that high water line is never going to see water unless The Great Flood arrives...but nevertheless...TVA makes the rules and a landowner is not even allowed to cut down a tree on that easement. TVA routinely takes shoreline pictures, and woe to the landowner who makes any changes without written permission from TVA. The fines imposed on the landowner are quite high. (the only reason I know as much about this is because I have had buyers who bought waterfront property and sellers who have sold waterfront - lots of additional paperwork concerning shoreline, docks, permits, etc. must accompany the documents)
