At least a month backlog of radioisotopes Western Health Region

It will take at least a month to clear up a backlog of specialized medical tests for western Newfoundland patients, officials said as a nuclear medicine department reopens.

The Western Health regional authority cancelled tests for 48 patients through Western Brook Memorial Hospital in Corner Brook after the Chalk River reactor shut down in November.

The supply of medical isotopes has been restored and officials were expecting to resume tests, including bone and heart scans, on Monday.

"It's wonderful," said Mike Brake, a nuclear medicine technologist who has worked at the Corner Brook hospital for three decades.

"This is the first incident in which we've had an interruption in service, so it's quite unusual for us, but we're so very happy to be back to normal."

Peter Dawe, executive director of the Canadian Cancer Society's Newfoundland and Labrador branch, said the reopening of the department will reduce anxiety for patients waiting for tests.

"It's very important news for people on the west coast, obviously, because you can't treat them and you're absolutely stuck until you get a proper diagnosis," Dawe said.

Western Health has already begun contacting patients to rebook cancelled appointments.

Chalk River resumes radioisotope production

The Canadian government-owned nuclear reactor at Chalk River, Ontario, was back in service this morning and expected to begin producing medical isotopes within four days, Atomic Energy of Canada Ltd said.

The National Research Reactor (NRU), which makes more than two-thirds of global supply of the radioisotopes used in cancer tests, was shut down in November for technical reasons, quickly triggering shortages.

On Wednesday, the Canadian government ordered the AECL, the government-owned nuclear technology company that operates the reactor, to restart the plant.

In spearheading the restart, Canadian Prime Minister Stephen Harper criticized Canadian Nuclear Safety Commission boss Linda Keen for not allowing the reactor to restart earlier this month because of what she said were safety concerns.

"NRU provides medical isotopes for about 25 million diagnoses and treatments a year," David Torgerson president of AECL's research and technology division, said in a statement.

"While we recognize the importance of the reliable production of medical isotopes, our first and foremost commitment is to safety. The NRU reactor has operated safely for the past 50 years and is safer now than ever before."

When injected into the body, the isotopes give off radiation that can be seen by a camera to diagnose cancer, heart disease and other medical conditions.

Chalk River produces medical isotopes for Canadian health-care company MDS Inc. and its MDS Nordion division, which is responsible for about 50 percent of world supply.

In addition to provoking shortages of medical isotopes in Canada and outside the country, the shutdown of the Chalk River reactor sparked a furious debate in parliament and changes at the AECL.

On Friday, Harper said he accepted the resignation of Michael Burns as AECL's chair of the board, effective Dec. 31.

He also announced the appointment of Glenna Carr as the new chair and Hugh MacDiarmid as chief executive officer.

Chalk River restarting isotope production

The nuclear reactor whose shutdown created a critical shortage of radioactive isotopes used to diagnose and treat cancer patients in Canada, the U.S. and many other nations, will resume its operation shortly.

Atomic Energy of Canada Ltd. said yesterday that it expected to begin producing the medical isotopes within seven or eight days.

The announcement came a day after the government scrambled to pass legislation allowing the company to bypass Canada's nuclear safety watchdog and immediately restart the 50-year-old reactor at Chalk River, Ontario.

The reactor was shut down Nov. 18 for maintenance and was scheduled resume operation Nov. 23.
But the Canadian Nuclear Safety Commission ordered an indefinite stoppage after discovering the reactor had been running for a year without the emergency power system being connected to two cooling pumps.

Prime Minister Stephen Harper said there was no risk of a meltdown with the startup. Company executives proposed an interim fix, in which one pump will be hooked up to the emergency power supply.

The reactor produces a radioactive substance called molybdenum-99, which is processed and packaged into canisters that are sold to big hospitals and specialized pharmacies.

The cylinders, in turn, are "milked" for technetium-99, which is used on patients. Technetium-99 is injected into patients undergoing body scans to assess a wide variety of conditions, including cancer, heart disease and bone or kidney illnesses.

Health Minister Tony Clement said he couldn't believe the AECL didn't inform health officials about the extended shutdown.

"I think it's shocking quite frankly," Clement told reporters yesterday. "... If there is an issue of extended shutdown in the future, Health Canada has to be notified immediately."

Decision made by the Commons: Chalk River "open for the public"

The Commons have decided last night to restart Ontario's Chalk River nuclear reactor and resume the production of medical radioisotopes.

Health Minister Tony Clement said this decision balances safety issues at the plant with the urgent need for the product.

The government introduced emergency legislation last night that will compel the plant to restart operations immediately, at least for 120 days.

Atomic Energy of Canada Ltd. shut down the plant for scheduled maintenance last November. The closure was then extended when serious safety concerns were discovered by the Canadian Nuclear Safety Commission, the federal watchdog for the industry.

Last night's bill allows the plant to restart, but suspends the CNSC's oversight of the Chalk River facility.

"A reasonable decision," according to Clement.

The commission made its decisions based on concerns from scientists and engineers over the system used to cool the reactors, and the possibility of a meltdown in an emergency situation.

But Clement said the government's priority is providing the isotopes to patients who need them.

"In terms of balancing that risk with the risk of cancer patients and heart patients who will not be able to get diagnosis or not be able to get therapy, I think the House of Commons made the right decision and approved the startup of the reactor," Clement told CTV's Canada AM today.

He said the government expects the plant to once again be producing usable isotopes within six to eight days.

The bill still needs to be passed by the Senate, which will likely happen today.

Green Party Leader Elizabeth May called for an inquiry into exactly what took place leading up to last night's decision.

She said Prime Minister Stephen Harper turned the reactor shutdown into a partisan issue and undermined Canada's nuclear regulator.

"Yesterday in the House, he attacked the Canadian Nuclear Safety Commission which is the regulatory body that oversees nuclear safety, referring to them as Liberal appointments and charging the Liberal party was getting in the way of people getting their medical isotopes," May told CTV's Canada AM. (click to see video)

"This was a moment for statesmanship, this is when the prime minister should have called on all parties to work together in the interests of Canadians to protect the supply of radioactive isotopes."

She said the situation sets a dangerous precedent for other Canadian communities that host nuclear reactors.

"These are experts in nuclear safety and the chairperson Linda Keen has now been undercut by the prime minister," May said.

"So the next time Canadians living near a nuclear reactor should be concerned if there's a safety defect in a reactor, AECL is going to thumb their nose at the regulator and know the prime minister is going to come to their defence and blame the regulator?"

The Liberals had threatened to refuse to give the bill the unanimous support necessary to bypass the legislative process.

But all of the political parties eventually agreed to fast-track the legislation through the House and Senate.

MPs passed the vote late Tuesday night, with the NDP and Bloc Quebecois backing it.

The Liberal-dominated Senate, which also agreed to stay late, was expected to put the bill to a vote by early today.

"Isn't this political system just great? Although you might not agree with the decision, at least some real decisions are being made!"

"I wonder though, who's going to pay the bill if there's going to be a meltdown!"

Isotopes Chalk river: production could start very soon

Chalk River Part 4

"The continuing actions of the Liberal-appointed nuclear safety commission will jeopardize the health and safety and lives of tens of thousands of Canadians," Harper said today.

The Liberals shot back.

"Attacking the regulator and taking him out of the process is going to make the problem worse," charged Deputy Liberal Leader Michael Ignatieff.

The shutdown has led to radioisotope shortages throughout North America and other parts of the world that have delayed diagnostic testing, therapies and surgeries involving nuclear medicine. AECL has said it is unlikely the reactor will be back to full production until mid-January.

Legislation to be introduced Tuesday will call on the CNSC, the Canadian Nuclear Safety Commission, to reopen the reactor for 120 days. During that time, the reactor's operators will be expected to bring in the changes that CNSC has said are needed.

The proposed legislation was the topic of heated debate today, with Opposition members demanding to know whether it was safe to re-open a facility the country's nuclear watchdog has said does not meet safety standards.

"There will be no nuclear accidents," said Harper, responding to the heckles of Opposition members. "What there will be is a growing medical crisis if all members of the House don't support the legislation," he said.

The National Research Universal reactor is now 50 years old. It was supposed to have been decommissioned in 2005. But a plant designed to replace the aging facility is six years behind schedule and would not produce radioisotopes until late 2008.

The CNSC extended NRU's operating licence until the problems with the new reactors can be sorted out.

But the commission's director-general, Barclay Howden, said the licence was issued based on assurances from AECL that an emergency power system connected to cooling pumps had been installed. Safety regulators found out only last month that that those pumps were not installed.

The CNSC has said several new safety standards must be met before the reactor can be reopened. AECL employees are working around the clock and are in the process of completing the installation of one pump and have secured all necessary components to assemble the second pump.

The company says returning the NRU reactor to service, on an interim basis, using one coolant pump with the emergency backup power connected while work is completed on the second pump will allow the "safe operation of the reactor."

The "heroic efforts" by staff means the facility could be restarted on December 20, if all went well.

"Within three to four days we start delivering radioisotopes and within seven days we're at full production," said AECL spokesman Dale Coffin.

The reactor might restart as soon as Wednesday if the Conservative government succeeds in pushing through emergency legislation allowing AECL to use a back-up method.

The Ontario Association of Nuclear Medicine says that this is good news for the about 50,000 Canadians and 160,000 Americans who would have their tests postponed for each month the reactor remains shut down.

Breaking news: federal government to legislate temporary production of radio isotope at Chalk River


CTV reports that the federal government is set to introduce emergency legislation later today to compel the Chalk River nuclear reactor to restart for 120 days to allow the production of medical radioisotopes.

The National Research Universal (NRU) reactor in Chalk River, Ont., which is operated by Atomic Energy Canada Ltd. (AECL) was closed for repairs on Nov. 18.

The Canadian Nuclear Safety Commission (CNSC) has said several new safety standards must be met before the reactor can be reopened. The repairs have taken longer than expected, leading to radioisotope shortages throughout North America.

That has delayed diagnostic testing, therapies and surgeries tremendously.

More than two-thirds of the world's medical isotopes are produced at the publicly-owned reactor.

CTV reports further that if the legislation passes, the reactor will be allowed to re-open for three months to resume production of the radioisotopes.
