Multinational consortium yields to public pressure on nuclear dump plan

(Ottawa, October 30, 2017) The multinational consortium running Canadian Nuclear Laboratories (CNL) and managing Canada’s federally-owned radioactive waste announced on Thursday (October 26th) that it will remove intermediate-level waste, which requires remote handling, from its plans for a giant radioactive mound beside the Ottawa River at Chalk River, Ontario.

Citizens’ groups who have been working for months to sound the alarm about the CNL proposal hailed the announcement as a partial victory. Over 200 submissions, most highly critical, were sent to the Canadian Nuclear Safety Commission during the public comment period for the project’s environmental impact study that ended in August.

CNL said in a press release October 26th that it was responding to comments from the public and the Canadian Nuclear Safety Commission, and that wastes intended for disposal in the proposed facility will meet guidelines for low level radioactive waste set out by the International Atomic Energy Agency (IAEA).

“We are pleased that our concerns are being heard,” said Johanna Echlin of the Old Fort William Cottagers’ Association, based in Sheenboro Quebec. “We said from the start that the facility should not contain “intermediate level” waste which is supposed to be disposed of in underground caverns according to the IAEA.”

There is still a long way to go before the proposal could be considered acceptable, according to Echlin. She notes that even “low level” radioactive waste is not supposed to be disposed of on top of the ground in a mound according to the IAEA. “It’s only common sense”, says Echlin. “You don’t have to be a rocket scientist or nuclear engineer to understand that radioactive waste should not be placed on plastic liners that will deteriorate long before the waste becomes harmless.”

“Low-level” waste is a misnomer that causes a lot of confusion, according to Dr. Ole Hendrickson of Concerned Citizens of Renfrew County and Area. “Low-level” waste is so named because it can be handled without using robots or special shielding, unlike used nuclear fuel rods which can provide a fatal dose of radiation within seconds to a person standing a few feet away.

“Low-level” radioactive waste can contain very hazardous materials, says Hendrickson. “Man-made isotopes such as plutonium, neptunium, and americium have extremely long half lives. They are highly toxic and will be around for thousands of years. Yet significant quantities are destined for this facility if it gets approved.”

Citizens groups say the proposed technology, an “engineered mound” similar to a municipal landfill, is not acceptable. They would like to see a “state-of-the-art” facility that would keep the radioactive materials out of the air and water for as long as they remain harmful, which could be longer than 100,000 years.  Facilities currently under construction in Finland and France which utilize engineered caverns in stable rock, tens of metres below the surface, would be much safer and could serve as an example for a new Canadian facility.

Dump opponents are also concerned about the site for the facility. “You couldn’t choose a worse site for this dump if you tried,” according to Echlin, “on the side of a hill, that would have to be deforested, and smack in the middle of a wetland that drains into the Ottawa River only a kilometre away”.

Proximity to the river is causing worry about possible contamination of drinking water since the Ottawa River is a drinking water source for millions of Canadians downstream of Chalk River in cities such as Ottawa-Gatineau and Montreal.

Ole Hendrickson of the CCRCA notes that siting was not done according to IAEA guidance that calls for a site that can ensure the environment will be adequately protected during the entire lifetime of the facility. “CNL should explore the 70,000 acres of federal land adjacent to the Chalk River Labs property to find a more suitable location,” Hendrickson said. “With a better location, away from the river and in stable rock, we could all get behind this project and build a facility that Canada can be proud of,” he added.

Scientists decry plan for Ontario nuclear-waste site

Former AECL scientists are condemning a plan to build a nuclear waste facility at the Chalk River site on the Ottawa River, saying it would be ill-equipped to handle the level of radioactive material planned for it.

The government-owned, private sector-operated Canadian Nuclear Laboratories (CNL) is proposing to build a $325-million facility to dispose of a large quantity of low- and intermediate-level waste generated from the demolition of aging buildings and other contaminated material generated over the past 65 years.

But several former senior scientists who worked there say the CNL proposal is seriously flawed and represents a threat to human health and the environment.

In 2015, the Canadian National Energy Alliance consortium won a contract to manage the Chalk River laboratories. The group includes SNC-Lavalin Group Inc. and U.S. engineering giants, CH2M Hill Inc. and Fluor Corp.

The former Conservative government split up the country’s nuclear flagship, Atomic Energy of Canada Ltd., selling its commercial business to SNC-Lavalin and retaining its research operations, including Chalk River, in CNL.

Ottawa is financing a $1.2-billion, 10-year effort to transform the aging Chalk River site, where the Candu reactor was developed. CNL is constructing some new facilities and demolishing older buildings. The company is also managing the site’s longer-term decommissioning.

The Canadian Nuclear Safety Commission (CNSC) is currently reviewing CNL’s plan for the nuclear waste disposal facility that would be a five-storey-high, dome-like structure and would hold one million cubic metres of low- and intermediate-level radioactive waste. The material is generated and stored on site, and the new facility is meant to provide permanent disposal.

David Winfield, a former senior scientist in safety management at AECL, said international standards suggest permanent disposal of intermediate-level radioactive waste should be done in vaults built deep underground in impermeable rock.

“The proposed design seems not to be appropriate to handle that level of waste,” Mr. Winfield said in an interview Tuesday. In addition to his role at AECL, Mr. Winfield has done consulting work on safety issues for the International Atomic Energy Agency.

He also worries CNL is locating the disposal facility in a swampy area of the sprawling Chalk River site, which could cause material to leach from it.

Another former AECL senior scientist, William Turner, said the new management appears to be rushing the plan in order to have it operational by 2020, and worries they are driven by financial considerations, including performance bonuses. “If this isn’t done right, they will walk away with pockets full of money and Canadians will be left with an enormous bill,” Mr. Turner said in an interview.

In a submission to the regulator last month, a former AECL director of safety engineering and licensing said CNL’s proposal “employs inadequate technology and is problematically located.”

“The proposal does not meet regulatory requirements with respect to the health and safety of persons and the protection of the environment,” Dr. J.R. Walker said in a lengthy critique of the plan.

CNL president Mark Lesinski defended the company’s proposal, saying the near-surface facility will provide “safe and permanent disposal” of radioactive materials.

In a statement provided to The Globe and Mail, Mr. Lesinski said the company carried out extensive geotechnical and hydro-geological tests to ensure the location was the best place to put it.

The site will primarily contain low-level radioactive waste – which requires no shielding for exposure – while more dangerous intermediate-level waste will represent no more than 1 per cent of the total material, he said.

“As proponent/licensee, CNL must demonstrate to the regulator (CNSC) that inclusion of these limited quantities of [intermediate level waste] is safe,” Mr. Lesinski said.Editor’s note: An early version of this article incorrectly identified Dr. J.R. Walker as Dr. Robert Walker.

Giant Radioactive Waste Dump on the Ottawa River: New revelations alarm citizens’ groups

(Ottawa, Ontario, April 3, 2017)  The draft environmental impact statement (EIS) for a proposed giant nuclear waste dump along the Ottawa River is ringing alarm bells for citizens’ groups.   It reveals that the dump would contain plutonium and dozens of other waste products created by nuclear reactors,  many of which will be radioactive for hundreds of thousands of years.

The proposed “Near Surface Disposal Facility” (NSDF) would be built on a 34-hectare site about one km from the Ottawa River at Canadian Nuclear Laboratories in Chalk River, Ontario.  The site is about 150 kilometres northwest of Ottawa, across the river from the Municipality of Sheenboro in the Province of Quebec.  The dump would be similar in design to a municipal landfill.  It would be used for permanent disposal of up to one million cubic meters of “low-level” and “intermediate-level” radioactive wastes in a mound up to 25 meters high.

The draft environmental impact statement (EIS) was released on March 17th.  A CNSC (Canadian Nuclear Safety Commission) decision on approval of the facility is expected in January 2018 and construction could begin soon after.

Johanna Echlin of the Old Fort William Cottagers’ Association was shocked to learn that the dump would contain very long-lived radionuclides. “How can it possibly be ethical and environmentally-responsible to put plutonium and other very long-lived radioactive wastes in a landfill beside the Ottawa River?” she asks. “I have talked to many people on both sides of the river, all the way to Montreal, and everyone I have spoken to thinks this is a terrible idea.”

Plutonium is one of many radioactive byproducts of nuclear fission that would be present in significant quantities in wastes disposed of in the NSDF.  Inhaling or ingesting plutonium or other radionuclides (e.g., in dust from the waste dump or runoff into the river) would increase risks of cancers of the lung, bones, blood and liver.

Dr. Ole Hendrickson is reviewing the draft EIS for the Concerned Citizens of Renfrew County and Area.  He says that the landfill-type design would expose radioactive wastes to wind, rain and snow.  Long-lived radioactive wastes would be hazardous long after plastic liners had deteriorated and leachate collection and treatment had ceased, and would spread into surrounding wetlands, lakes and waterways.   

“By failing to provide adequate waste containment, this proposal flagrantly disregards the International Atomic Energy Agency’s safety standard for disposal of radioactive waste,” warns Hendrickson.

The public has 60 days to respond to the EIS (until May 17, 2017).  It is posted on the Canadian Environmental Assessment Agency website at: http://www.ceaa-acee.gc.ca/050/document-eng.cfm?document=118381
