Looks like a nightmare. From the News, the building was basically used to store radioactive source on the time of Marie Curie time, when people had no idea about basic radiation protection. So the building is full of radioactive dust, and the initial plan was to disconstruct it and store the fragments as in a radioactive waste landfill.

Moving it seems like even more complicated (even though it means : No need to pay for radioactive waste storage). and I am not sure on the interest of keeping that building compared to others
