* Ministers to meet to discuss safety of Ohi reactors-govt

* Safety concerns run deep, local govts want new measures

(Adds comments by Trade Minister Edano)

By Risa Maeda

TOKYO, April 3 (Reuters) – Japan needs more time to decide

whether to restart two offline nuclear reactors, the trade

minister said on Tuesday, as concerns about a summer power

crunch vie with safety worries in the wake of last year’s

Fukushima crisis.

Prime Minister Yoshihiko Noda will meet three cabinet

members on Tuesday to discuss restarting the reactors, but will

not make any immediate decision, Trade Minister Yuki Edano, who

holds the energy portfolio, told reporters.

“Safety should be ensured to avoid massive leaks of

radioactive materials as occurred in the Fukushima crisis even

if an earthquake and tsunami that exceed past expectations

occur,” Edano told reporters.

“We should also obtain the understanding of local

communities in that regard.”

All but one of Japan’s 54 reactors have been shut, mostly

for maintenance checks, over the months since the disaster at

Tokyo Electric Power’s Fukushima plant, triggered by a

huge tsunami in March 2011. The remaining reactor is set to be

closed for maintenance on May 5.

Kansas Electric Power’s No.3 and No.4 reactors at

Ohi nuclear plant in Fukui prefecture, western Japan, are the

first to have passed government-imposed, computer-simulated

stress tests, a necessary step before any restart.

Energy markets are keen to know when the Ohi reactors will

go back on line. Their restart could reduce imports of liquefied

natural gas equivalent by about 2 million tonnes a year.

To make up for the lost nuclear power, Japan’s utilities

burned 25 percent more imported liquefied natural gas –

equivalent to a total of 51.8 million tonnes – and 150 percent

more crude oil in the year to February, according to the latest

power industry data. [ID: nL4E8EE3M9]

The government, however, must persuade wary locals that the

plants are safe after last year’s nine-magnitude earthquake and

tsunami triggered the world’s worst nuclear crisis in 25 years.

Nuclear power supplied about 30 percent of Japan’s

electricity before the crisis, and Noda’s administration is now

debating what role it should play in the future.

Japan’s defences against another major tsunami and the

safety of its nuclear plants were thrown into further doubt

after two official studies released at the weekend predicted

much higher waves could hit and that Tokyo quake damage could be

bigger than it was prepared for.
