HELSINKI, July 30 (Reuters) - A small fire at the construction site for a new nuclear reactor in Olkiluoto, western Finland, spread to two floors of the reactor building, before it was put out, plant operator Teollisuuden Voima (TVO) said on Wednesday.
"A small amount of contruction materials had caught fire," TVO said in a statement, and added the fire was noticed at around 2:00 a.m (2300 GMT) and it was put out four hours later.
