Russia`s nuclear chief said Japan may be seeking to reduce liabilities of insurance companies.
Sanya: Japanese authorities may be exaggerating the scope of the country`s nuclear disaster to reduce the liabilities of insurance companies, Russia`s nuclear chief said on Wednesday.
Japanese officials on Tuesday upgraded the severity of the emergency at the tsunami-damaged Fukushima Daiichi plant to a 7, putting it on par with the 1986 Chernobyl nuclear disaster, the world`s worst.
"It is hard for me to assess why the Japanese colleagues have taken this decision. I suspect, this is more of a financial issue, than a nuclear one," Sergei Kiriyenko said on the sidelines of a meeting of major developing economies in southern China.
"I guess that maybe it could be linked to the definition of force-majeure with regard to insurance. I would pay attention to that. It is a bit strange," Kiriyenko said without further elaboration.
Japan, which initially ranked the crippled plant at a 4, said it had taken time to measure radiation from the plant after it was smashed by March 11`s massive quake and tsunami.
Officials were quick to add that increasing the rating to the highest level on a globally recognised scale did not mean the situation had suddenly become more critical.
According to the International Atomic Energy Agency, a level 7 incident means a major release of radiation with a widespread health and environmental impact, while a 5 level is a limited release of radioactive material, with several deaths.
No radiation-linked deaths have been reported since the earthquake and tsunami crippled the plant.
Several experts have agreed that Japan`s new rating exaggerated the severity of the crisis and did not compare with Chernobyl, which blew the roof off a reactor and sent large amounts of radiation across Europe.
Kiriyenko said the damaged plant should have initially been ranked at a 5 or 6, a level he said still matched the severity of the leaking radiation given the current low risk of a blast.
"Our estimates showed that the level was between 5-6. Today it doesn`t reach the 6th level," he said.
Kiriyenko`s agency, Rosatom, is building a slew of reactors at three sites in energy-hungry India, which plans to fuel economic growth with 63,000 megawatts of nuclear power by 2032.
Russia`s nuclear stations built overseas, including the Kudankulam power station project in India are safe, Kiriyenko said, ruling out a Fukushima-like disaster scenario.
"If you think of a station that would resist all possible tsunamis, earthquakes, power supply outages, you will get Kudankulam in the end," he said, adding that the Indian side is now carrying out some additional safety checks on the project.
