JCO Co. is likely to pay around 10 billion yen in compensation over last September's nuclear accident at its uranium processing plant in Tokai, Ibaraki Prefecture, local government officials said.

The officials reached the estimate Saturday night after all 578 compensation claims in Tokai were calculated in negotiations between JCO and local residents and businesses. The talks were mediated by the Tokai government.

JCO said it plans to announce the compensation total this week. The amounts of compensation paid in 3,650 cases filed in other municipalities of Ibaraki Prefecture were calculated in late February.

The compensation owed in 491 cases in Tokai and 3,143 in the rest of the prefecture -- about 85 percent of all cases -- has already been agreed, according to officials involved with the talks.
