Bury the damaged chernoby nuclear reactor

I was wondering whether they have considered the possibility of burying the damaged chernobly reactor. Bringing radioactive materials to the surface of the earth is like raising a deadly monster that kills all life. Leaving these radioactive isotopes on the surface is just as deadly. The nuclear experts can advise whether one can tunnel below the damaged chernobyl reactor and let it drop down and fill it up with cement or sand or any suitable material. If not, think of other ways to bury the damaged reactor. Uranium-235 has a half-life of 700 million years. Assuming one generation is 100 years, uranium 235 has a half life of 7 million generations. This deadly monster has a half life of 7 million generations.
