RE: burying radioactive reactors a last resort
RE: burying radioactive reactors a last resortJapan must cool and isolate the nuclear fuel at its crippled atomic power station before trying to encase the reactors in a Chernobyl-style concrete sarcophagus, nuclear experts believe.
...
The Chernobyl sarcophagus, built in just over six months on the orders of panicked Soviet authorities who had remained silent for days before even acknowledging the accident, was not designed to last more than 20 to 30 years.
Its roof was supported on one side by the wall of the old reactor building and the structure had to be reinforced in 2008.
"Holes and fissures in the structure now cover 100 square metres, some of which are large enough to drive a car through," according to Chernobyl Children International, a UN-sponsored charity organization.
...
A new 29,000 tone convex steel structure -- called the New Safe Confinement -- is being financed by the Chernobyl Shelter Fund.
The $1.4 billion structure, tall enough to house the Statue of Liberty, will completely cover the old sarcophagus and will allow the reactor to be eventually dismantled. It is designed to last for a century.
