Nuclear-safety agency not adequately inspecting power plants, watchdog says

The federal agency charged with ensuring the safety of Canada’s nuclear
power plants is unable to prove that it is inspecting those facilities
often or thoroughly enough or that it has the number of staff required
to do the job, says a new report by the Commissioner of the Environment
and Sustainable Development.
The audit released by the commissioner, Julie Gelfand, on Tuesday as
part of her fall report calls into question whether the Canadian Nuclear
Safety Commission (CNSC), which is often accused by environmentalists of
being too close to the industry it was established to monitor, is
providing proper oversight of the country’s nuclear reactors.
The auditors could find no proof that the CNSC has determined how many
inspections are needed to ensure that nuclear power plant operators are
complying with their licensing and regulatory requirements. Nor, says
the audit, could the regulator demonstrate that it takes risks into
account when making decisions about which inspections it would and would
“I think it’s pretty serious,” Julie Gelfand, the environment
commissioner, told a news conference. ”Given that the nuclear industry
is a precision industry, it’s pretty serious if something goes wrong.”
Ms. Gelfand said the audit does not inspire confidence in the safety of
the nuclear system, or provide assurances that important things are not
The audit found that 75 per cent of inspections carried out by the CNSC
were done by an inspector who was not following an approved guide.
“It’s a bit like an airline pilot who doesn’t go through his check list
before taking off,” said the commissioner. “That means that the
commission can’t tell us, and show us, that they are covering in their
site inspections all of their requirements.”
The audit follows on the heels of an anonymous letter sent earlier this
year to CNSC president Michael Binder, purportedly written by
technologists inside the regulator, that pointed to five separate cases
in which the commission’s staff sat on relevant material about risk or
non-compliance that might have called the safety of a plant into question.
Dr. Binder, who was appointed by the previous Conservative government
after it fired former president Linda Keen when she balked at skirting
safety rules, subsequently questioned whether that letter was part of a
“conspiracy theory” concocted by outsiders.
But the CNSC management agreed with all of the recommendations made by
the environment commissioner to correct the deficiencies that her audit
team uncovered in the regulator’s inspection regime.
Among other things, the audit says the CNSC conducted only about 48 per
cent of the inspections of nuclear plants in 2013-14 and 2014-15 that
should have been scheduled under the regulator’s five-year plan.
“The decisions about which inspections the CNSC would and would not
carry out from the five-year plan were based on professional judgment
and the rationales for those decisions – such as on how risks were taken
into account – were not documented,” says the audit.
In some cases, the inspections were not done because inspectors and
technical specialists were not available. The audit says the CNSC could
not show that it had assigned an appropriate number of staff to deal
with the risks.
In fact, the regulator’s senior managers told the auditors that they
believed there were enough inspectors to do the work and that more were
being assigned as issues arose. But, wrote the auditors, “we were told
by site inspectors and site supervisors at every nuclear power plant
that there were either not enough inspectors at their sites, or not
enough at the levels needed.”
NDP Leader Tom Mulcair asked Prime Minister Justin Trudeau on Tuesday to
explain why he continues to support Mr. Binder in the role of CNSC
president after the letter of last summer and the problems that were
uncovered by the auditor.
Mr. Trudeau did not respond directly to the question but said the
Liberal government takes the question of nuclear safety seriously and
will work to ensure that Canada maintains the highest standards.
After the daily Question Period in the House of Commons, Kim Rudd, the
parliamentary secretary to Natural Resources Minister Jim Carr, said the
government does have confidence in the CNSC and said she understands
that the regulator is already beginning to address the auditor’s
Japanese officials have admitted that there were inadequate inspections
of the nuclear power plant in Fukushima Japan in the years leading up to
the disaster of 2011 when an earthquake and tsunami disabled three
reactors, causing their cores to melt down and creating the largest
nuclear disasters since Chernobyl.
In response to the audit, the CNSC says it is updating its five-year
plan and will review both its staffing allocation and the frequency and
type of inspections that are needed to ensure compliance.
But Shawn-Patrick Stensil, a senior energy analyst with Greenpeace
Canada, said the audit proves that “Canada’s so-called nuclear watchdog
is all bark and no bite. The CNSC needs to actually oversee nuclear
safety instead of just reassuring Canadians nuclear power is safe.”
CNSC review dismissing nuclear-safety concerns called a ‘sham’

An internal review by the Canadian Nuclear Safety Commission dismisses
allegations that important information was withheld during the licensing
of nuclear plants but two nuclear scientists say the review is “less
than impartial” and a “sham” that should give Canadians no comfort.
In June, CNSC president Michael Binder received an anonymous letter,
purported to have been written by employees at the nuclear regulator,
that pointed to five separate cases in which the commission’s staff sat
on relevant information that might have called the safety of a nuclear
plant into question.
Peter Elder, a strategic adviser within the CNSC’s regulatory operations
branch, who says he was able to maintain a neutral position because he
did not work on the safety of nuclear power plants between 2008 and
2015, conducted a review that concluded late last week that none of the
five cases point to any safety issues.
Most of the allegations in the anonymous letter relate to inadequate
“probabilistic safety assessments” (PSAs), which forecast what could go
wrong in a reactor, the probability of those situations occurring and
the potential consequence.
“In most cases, the anonymous letter overstates the importance of the
PSA to the overall safety case,” Mr. Elder wrote. PSAs, he wrote, are
not meant to be used without other types of safety analyses, or to set
operational safety limits, and care should be used when regulatory
conclusions are drawn from their results.
“There was also no evidence to support the author’s opinion that ‘CNSC
commissioners do not receive sufficient information to make balanced
judgments,’” Mr. Elder wrote.
He recommended that the CNSC make a better effort to clarify the role of
PSAs in the regulation of nuclear generating stations, that the “depth
and scope” of the technical reviews performed to support licensing be
clearly documented, and that management should reinforce with staff all
of the processes that are available for raising issues of this nature.
But two nuclear experts have written subsequent letters to Mr. Binder
asking him to discard Mr. Elder’s review and to allow an arm’s-length
inquiry into the allegations of the anonymous whistle-blowers.
Frank Greening, a nuclear chemist who is a former senior research
scientist at Ontario Hydro, the predecessor of Ontario Power Generation,
wrote that Mr. Elder’s claim to have conducted an independent
investigation was “quite extraordinary and ridiculous.”
Mr. Elder “cannot possibly be independent because he is an employee of
the CNSC,” wrote Dr. Greening. He asked Mr. Binder to “reject Mr.
Elder’s less than impartial review.”
In a telephone interview, Dr. Greening said PSAs have, for many years
“been taken very very seriously and formed the backbone of a licence
renewal. And now the CNSC turns around and says well actually, they’re
really not that important. That’s absurd.
“If I was one of those whistle-blowers, I would be very very distressed
at this stage of the game.”
In a second letter, Sunil Nijhawan, a nuclear safety engineer with more
than 35 years in the industry, wrote that Mr. Elder’s conclusions
display an ignorance of basic safety principles and the legislated role
of the CNSC.
“After a lifetime of working in PSAs I am now asking why so many of us
toiled for years and why the industry was forced to spend well over
$50-million on PSAs so far?” Dr. Nijhawan wrote. “Why are many in the
rest of the world doing brilliant peer-reviewed PSAs and using the
findings to not only improve operations, reduce risk and also come up
with improved designs?”
