Estimating is cheaper, he told a federal review panel on Wednesday.
KINCARDINE—Ontario Power Generation has taken a “cavalier attitude” to the potential hazards of nuclear wastes it plans to bury near the Bruce nuclear station, says a former OPG scientist.
And Frank Greening says the company did it to save money.
But OPG and Canada’s nuclear regulator told a federal review panel that the errors in their calculations pointed out by Greening, don’t alter the fact that the proposed waste site is safe.
Greening gave a technically dense but often scathing assessment of the company’s plans to entomb low- and intermediate-level radioactive waste 680 metres below ground on the shore of Lake Huron.
Greening discovered major errors in OPG’s statements of the types of waste and the radioactivity of materials destined for the site.
Greening, who holds a PhD in chemistry, worked for OPG and Ontario Hydro from 1978 until 2000.
Greening’s critique sent OPG and the Canadian Nuclear Safety Commission back to re-do calculations, which were presented to the panel on Wednesday.
For example, the CNSC reported that when Greening’s corrections were made, the radiation dose to members of the public resulting from a terrorist bomb damaging a package of scrapped pressure tubes would be three times more than originally calculated.

Greening accused OPG of estimating what materials, in what proportions, are contained in waste produced by their nuclear power stations — instead of taking samples.
Estimating is cheaper, he said.
“OPG has chosen to skimp on the costs of properly characterizing these piles of radioactive waste, perhaps because the analysis of just one sample costs over a thousand dollars,” Greening said.
After Greening pointed out mistakes, OPG said that they resulted from OPG’s use of “available data” in 2010, when the information was prepared.
“This is simply not true,” Greening said. “OPG did not use available data, but used fabricated data instead.”
