The Canadian Nuclear Safety Commission has started hearing from the public on the future of Lepreau.
New Brunswick's nuclear power plant, which generates as much as 40 per cent of the province's home-grown power supply, will see its operating licence expire in June. N.B. Power is asking the federal regulator to approve a renewal of 25 years.
On Tuesday, some Indigenous intervenors urged the Commission to reject that request.
They said N.B. Power has not fully addressed the concerns they've raised about the duty to consult with First Nations nor the questions they have about the plant's safety and decommissioning plans.
Passamaquoddy ask for three-year renewal
The Passamaquoddy Recognition Group, a non-profit organization that represents the Peskotomuhkati, whose traditional territory includes Point Lepreau, is asking the commission to renew the licence for three years.
For one thing, they say, 25 years is far outside the normal.
Only three Canadian nuclear power plants have been renewed for a full decade: Darlington, Bruce and Pickering.
Lepreau's 15 renewals since it started operating in 1982 have mostly been two years long.
"We're asking only that you maintain the status quo," said Kim Reeder, who works for the PRGI.
Any licence renewal will result in "fresh new hazardous waste" being deposited on traditional land without their consent, said the group.
And going 25 years without a public hearing would go against the spirit of meaningful engagement, said Chief Hugh Akagi.
"We're losing the voice of a generation," he said.
Where's the money to shut down?
Experts hired by the Passamaquoddy said N.B. Power has not set aside enough funding to dismantle the Lepreau reactor, dispose of its nuclear waste and return the site to its natural state.
"The bottom line cost…translates to about $1.83 billion, expressed in 2022 Canadian currency," concluded Gordon Edwards, a nuclear consultant and president of the Canadian Coalition for Nuclear Responsibility.
"That's two and a half times larger than the financial guarantee that the Commissioners are being asked to approve in the present hearings."
N.B. Power says it is required to report every year to the CNSC on the status of the decommissioning financial guarantee.
The utility says the total value of N.B. Power 's 2020 financial guarantee was $755 million against a funding requirement of $714.5 million.
And as of March, 2021, the actual amount of the guarantee was $842.8 million.
The Passamaquoddy say their experts have also flagged that Lepreau releases higher levels of radioactive tritium than any other Canadian reactor.
CNSC president Rumina Velshi tried to press N.B. Power to explain what was being done about that.
"For the last four years … it's an increasing trend," said Velshi, referring to the data in the written submission. "There is no fluctuation. It's just going up from 2017, '18, '19 and 20."
"You didn't explain why there is a difference between Lepreau and other CANDU reactors. What are you doing to eliminate the source and change the trend?"
CBC asked to interview Jason Nouwens, N.B. Power's director of external affairs to explain and elaborate on some of what was said in response to Velshi, but the utility said the commission had prohibited N.B. power staff from giving media interviews outside commission proceedings.
During proceedings, N.B. Power did admit that it does release more tritium than its peers.
Senior Health Physicist ·Jennifer Allen says elevated releases do occur when N.B. Power performs activities on its moderator system but she said levels are monitored daily and workers are protected.
"We recognize that this is a significant radiological hazard - not just from an environmental perspective but also for the workers who have to perform maintenance on these systems as well," she said.
Nouwens told the commission that increases do result from proactive maintenance but they're always planned in terms of ALARA, he said.
That's the acronym in the nuclear power industry for doing everything possible to reduce radiation exposure to "as low as reasonably achievable".
Mi'gmaw ask for 15 years
Mi'gmawe'l Tplu'taqnn Incorporated, a group created by Mi'gmaq First Nations, said Lepreau's licence should be renewed for no longer than 15 years.
"N.B. Power was unable to articulate the clear advantage of securing a 20 or 25 year licence rather than a ten-year licence," said their submission.
"MTI shares the Commission Members' concerns that a longer licence duration may negatively affect both public perception of the Commission's oversight, and opportunities for meaningful engagement with First Nations and other communities."
While recognizing N.B. Power's efforts to engage Mi'gmaq rights holders, MTI noted that more was needed to increase First Nations' confidence in the Point Lepreau Nuclear project.
They are calling for Indigenous people to be involved in environmental monitoring.
They're also asking that all decisions involving Lepreau be made with guidance from Indigenous knowledge which they defined as the body of knowledge, practice, and beliefs handed down through generations.
Hearings end on Thursday
The public hearings will continue Wednesday and run until midday Thursday.
Wednesday's agenda includes presentations from the New Brunswick Emergency Measures Organization, the Musquash Volunteer Fire-Rescue Department, the Canadian Nuclear Association and the CANDU Owners Group.
