NB Power is seeking a one-year extension of its licence to operate the Point Lepreau Nuclear Generating Station amid criticism over the reactor's refurbishment delays.

Utility officials appeared before the Canadian Nuclear Safety Commission in Ottawa on Wednesday requesting a renewal for a licence that is set to expire this summer.

The regulatory body is expected to take six weeks to render its decision on the licence renewal.

Normally, NB Power requests a five-year licence, but because the nuclear refurbishment project is expected to be completed next year, the extension to June 2012 is being sought.

The $1.4-billion refurbishment project is three years and roughly $1 billion over budget.

Dan Togyesi, a member of the Canadian Nuclear Safety Commission, emerged as a new voice calling for more transparency on the Point Lepreau refurbishment project.

"You are quite behind the schedule. And I don't think the public opinion is satisfied with that," Togyesi said.

"But you should also show what you are doing, what you did, why you are delayed, and what you do ahead."

Atomic Energy of Canada Ltd. and NB Power were supposed to have Atlantic Canada's only nuclear reactor back producing power in 2009.

It is now expected that Point Lepreau will be generating power again in the fall of 2012.
