Vienna (ANTARA News/AFP) - The situation at Japan`s stricken Fukushima nuclear plant has not worsened "significantly" over the past 24 hours, an IAEA expert said Friday, but refused to say that he felt "optimistic".

"At the Fukushima Daiichi nuclear power plant the situation remains very serious. But there has been no signficant worsening since our last briefing," Graham Andrew, scientific and technical advisor to the head of the International Atomic Energy Agency, told a regular daily press briefing here using the same words the day before.

The current situation at units 1, 2 and 3 of the plant, whose cores had suffered damage from a number of explosions and fires since the devastating earthquake and tsunami nearly a week ago, "appears to be relatively stable," Andrew said. (*)
