Its about time they replaced the current shelter. I went to the reactor in 2009 and saw the decaying state of the current shelter for myself. It made me so nervous just seeing it as it really is falling apart. The new shelter is exactly whats needed even though it will 'ruin' the site from a historical point of view. When the area is truly safe for tourists (it really isnt right now as I was sick for a month after I went in 2009) it will almost be a shame that future generations cannot see the sarcophagus in its original state. However for the safety of not only Ukraine, but Belarus and Russia as well, its mad that it has taken almost 25 years to put a permanent shelter over the reactor to stop the risk of anything leaking from the remains.
