LEPREAU, N.B. - NB Power will provide an update today on the problem-plagued refurbishment of the Point Lepreau nuclear generating station.

The original $1.4-billion project to extend the life of the reactor by 25 years is running three years behind schedule.

The project is also more than $1 billion over budget.

Crews have experienced trouble getting proper seals on tubes at the heart of the reactor.

New Brunswick Premier David Alward wants the federal government to pay for the cost overruns.

It's the first refurbishment of a Candu-6 reactor by Atomic Energy of Canada Ltd., and the province argues New Brunswick shouldn't have to pay for the federal Crown corporation's learning curve.
