How did Chernobyl cope with the nuclear accident?

The reactor that had the explosion in entombed. The actual structure is problematical because it will not last nearly long enough. The other reactors have remained in use since the accident. The area around Chernobyl was, and remains, evacuated. A broader area has been taken out of use for various purposes, such as agriculture. Forest fires have to be carefully dealt with because the fires put radioactive materials into the atmosphere. People in the area have health problems that require attention, and the people who have not developed diseases need to be checked carefully for them.
