The C Reactor is one of the five nuclear reactors at the Savannah River Site, all of which no longer function as reactors. The C Reactor is similar to the K Reactor, where some 13 tons of deadly radioactive plutonium is in so called temporary storage at the plant. Officials won't allow photographs of the highly-protected K Reactor, which like the C Reactor often has vultures roosting on top or flying overhead. Michael Pronzato/Staff
