The Canadian Nuclear Security Fee says the newest air samples present beryllium emissions from the BWXT Nuclear Power Canada facility in Peterborough, Ont., stay beneath provincial limits and pose no threat to human well being and the surroundings.
Throughout Peterborough Public Well being’s board assembly on Wednesday, the fee offered an replace on the annual air high quality monitoring which is required across the facility on Monaghan Street. The corporate is positioned simply metres away from Prince of Wales Public College.
The Toronto-based firm utilities uranium and “small quantities” of beryllium — a light-weight metallic — to hitch parts of gasoline bundles on the Peterborough facility utilizing uranium dioxide pellets produced at its facility in Toronto. The pellets are then inserted into the tubes to create gasoline bundles.
CNSC director Andrew McAllister instructed the board that the general public continues to boost issues about beryllium use and ranges on the facility. The fee says in the newest air sampling carried out in the summertime of 2023, the hours of sampling had been prolonged from eight to 72. Hotter months (July to September) had been chosen to “maximize potential for beryllium assortment.”
One of many places for testing was on the Prince of Wales Public College faculty yard. The others had been on the south of the BWX facility inside its fence-line and east of the ability contained in the GE property fence line, as indicated on this fee slide:

He famous testing at web site 3 was “reduce brief” as a result of noise issues from residents alongside Wolfe Avenue, conducting 27 hours as an alternative of 72.
“With a view to conduct this sampling, the CNSC sourced a brand new sampler applicable for steady operations in antagonistic climate circumstances with the flexibility to run successfully over prolonged intervals,” stated McAllister.
He stated examinations of the samples decided that an “extraordinarily small quantity” of beryllium — 0.0000056 micrograms per cubic meter (µg/m³) — was discovered at web site 1 throughout monitoring in mid-July.
McAllsiter says that quantity is “nicely beneath” Ontario’s Ambient Air High quality Standards launch restrict of 0.01 µg/m³.
“This measurable beryllium could be coming from numerous pure and human actions,” stated McAllister.
He famous the opposite two websites had samples that had been “not above the detection restrict,” that means that the quantity discovered was smaller than what may very well be measured by lab strategies.

“These outcomes confirms that ranges of beryllium in air (round BWXT) are negligible and nicely beneath air high quality pointers which can be protecting of human well being and the surroundings,” he stated.
The director stated that even with testing hours prolonged, his workers “proceed to conclude” that the quantity of beryllium in air is “extraordinarily low and doesn’t pose any threat to the well being of the group or the surroundings at these concentrations.”
He famous that workers suggest that the unbiased environmental monitoring program for air sampling proceed as soon as each three years and that the corporate’s annual soil sampling for beryllium and uranium proceed. The sampling is required as a part of the BXWT’s licensing renewal settlement.
