HALIFAX – Fire officials say an evacuation zone remained in place Friday at a port in Halifax after four steel cylinders carrying weapons-grade uranium fell about six metres the night before as they were being unloaded from a container ship, prompting a radiation scare.
Phil McNulty, the city’s executive fire officer, said the area is being monitored by emergency crews after the cylinders carrying granular uranium hexafluoride fell.
Investigators with the Canadian Transport Emergency Centre were scheduled to arrive later Friday to the Ceres terminal in the city’s north-end to conduct a more detailed assessment, McNulty said.
“This is weapons-grade uranium. This is a volatile, dangerous substance,” he said.
McNulty said the material reacts with water and could react violently if it catches fire.
Firefighters had earlier determined there was no leak of radioactive material when the steel cylinders fell from a pallet as they were being lifted off the ship around 10 p.m. Thursday, landing in a contained area of the vessel.
“The bottom basically fell out of the container when they were off loading it at Ceres and the product was uranium hexafluoride,” McNulty told Global News.
There were no injuries and tests showed no one was contaminated at the terminal in Fairview Cove, though initial tests showed three to four times the “normal” radiation at the site–not considered dangerous.
“There’s radiation in the ambient air around us at all times,” said McNulty. “So all this represented was an increased level of normal radiation in the atmosphere.”
The granular substance was well contained in the cylinders, he added.
McNulty said the evacuation area at the port extends about 150 metres and will remain in place until after federal investigators arrive.
“We’re not working at the terminal,” said Ceres’ senior vice president Calvin Whidden. “I’m not putting anyone to work until we’re absolutely positive that there was no breech.”
Once the investigation wraps up, McNulty said the cylinders would be placed on a truck and continue to their destination.
The Canadian Nuclear Safety Commission said the uranium cylinders came from an enrichment facility in the United Kingdom owned by URENCO.
“The Cylinders are designed to withstand significant impact and initial investigations have confirmed there has not been any breach to the cylinders,” the commission said in an emailed statement.
Uranium hexafluoride is the chemical compound used in the gas centrifuge process to enrich uranium that is then used as reactor fuel or to arm nuclear missiles.
URENCO’s website says it is an international supplier of enrichment services for nuclear fuel used to generate electricity. A spokesperson for the company in London could not be reached for comment.
Firefighters evacuated the immediate area as a safety precaution after the accident Thursday night and the crew of the Atlantic Companion – which arrived in Halifax from Liverpool, England – were taken to a local hotel.
McNulty said there was a similar incident at a Halifax port in the late 1990s involving uranium hexafluoride, but there was no leakage.
“It’s very rare,” Whidden told Global News. “It’s a mechanical failure either of our crane, or a flat, or it’s a human error…We do between 150-200,000 containers a year and we don’t have one of these incidents a year.”
