The government plans to propose at next month's global nuclear security summit creating backup systems to secure electricity supplies in the event that terrorist attacks against nuclear plants knock out power sources.
The Noda administration intends to make the proposal at the Nuclear Security Summit to be held from March 26 to 27 in Seoul, and to have it incorporated it in a document adopted at the meeting, government sources said Thursday.
The government will emphasize the need to map out detailed procedures over how to deal with potential terrorist attacks against nuclear plants, drawing on the lessons from the Fukushima nuclear crisis, the sources said.
The government will also urge that general security measures at nuclear plants be enhanced, for example through introducing stricter identity checks for plant workers, they said.
Three of the Fukushima No. 1 plant's reactors suffered meltdowns after the March 11 quake and tsunami disabled power sources.
Prime Minister Yoshihiko Noda has expressed his readiness to attend the summit. He has repeatedly vowed to share the lesson's from Fukushima with the international community.
But as the Diet will be in the final stages of deliberations on the fiscal 2012 budget in late March, his attendance remains in doubt.
The summit, the second of its kind, will be cochaired by U.S. President Barack Obama and South Korean President Lee Myung Bak.
The inaugural summit took place in Washington in 2010 following an initiative by Obama and is part of efforts to promote his vision of a world free of nuclear weapons.
