I recently started mapping out the system of 113 EOWS and Modulators in the EPZ of the plant. Surprisingly there are still a few active 612s in their system. Sadly most, if not all, of the 408s have been removed and replaced with Mods in 2006. They use different sizes of Mods in the system, so far I found 6024/32s, 5020s, and 3012s. The 5020s and, to a lesser extent, 3012s replaced 408s with one found so far that was a new installation when it was installed. Chances are that the remaining EOWS sirens will stay since the plant will be closing in the next couple years. With 113 total there are bond to be more EOWS sirens in the system, so there is still a chance that a couple 408s were left in service.
