Engineers attempt to plug nuke plant leak

A 20-cm split allows radioactive water to spill into the Pacific Ocean

TOKYO - Highly radioactive water was still gushing into the Pacific Ocean from Japan's tsunami-crippled nuclear plant despite efforts to stop it with a chemical substance mixed with sawdust and shredded newspaper on Sunday.

The new approach was employed after concrete failed to seal a crack at a Japanese nuclear power plant incapacitated by last month's earthquake-spawned tsunami. A search of site found no other leaks.
