Scrapping the reactors could mean Japanese nuclear operators would decommission 21 units, or nearly 40 per cent of their pre-disaster fleet, saddling them will billions of dollars of costs to dismantle and decontaminate the facilities.

Before the March 2011 tsunami, nuclear power served about 30 per cent of Japan’s electricity requirements. The nuclear station shutdown forced Japan to use record quantities of imported thermal coal and liquefied natural gas to replace the lost generation capacity.

The Daini station, which has four reactors, also came close to a disaster, but retained enough back-up power to keep cooling going. Successive Fukushima governors had called for it to be scrapped.
Scrapping the Daini station will leave Tepco with just one potentially operational nuclear station, Kashiwazaki-Kariwa, where the company is trying to revive two of the eight reactors under new safety regulations against strong local opposition.
It will also leave Japan with 33 reactors, compared with 54 before the disaster: many operators decided to scrap older units that would cost too much to meet new safety standards imposed after the world’s worst nuclear catastrophe since Chernobyl in 1986.Source: Reuters
