Ottawa, St. Lawrence valley at risk of major earthquake

The insurance industry is warning that Canada is unprepared for the next major earthquake and that the risk is not confined to the well-known fault lines off the west coast.

A study released Tuesday by the Insurance Bureau of Canada suggests that a damaging and potentially deadly earthquake could hit the Ottawa and Saint Lawrence river valleys.

"I think this is the beginning of a wake-up call for consumers, for governments and for the industry as it relates to central Canada," said Don Forgeron, president of the Insurance Bureau of Canada.

After a string of major earthquakes around the world culminating in the devastating 2011 earthquake and tsunami in Japan, the insurance industry commissioned a study to assess the risk to Canada.

A US risk modelling company looked at what it called two plausible scenarios: a magnitude 9.0 earthquake off the west coast of Vancouver Island and an earthquake measuring 7.1 on the Richter scale with an epicentre near Quebec City.

However, one of the scientists behind the study warns the eastern earthquake could occur anywhere between Quebec City and the nation's capital.

People in eastern Canada particularly unprepared, bureau says "The entire corridor between Ottawa, Montreal and Quebec City is prone to earthquake risk, so think about the Ottawa River valley and the Saint Lawrence River valley," said scientist Jay Guin.

The research team estimated total losses at a staggering $75 billion for the west coast scenario and $61 billion in losses for the central Canada scenario.

Both potential earthquakes would also entail significant loss of life, said Guin.

The bureau said the insurance industry would be hard-pressed to meet all of the claims for either of the possible earthquakes.

People living in the eastern earthquake zone are particularly unprepared for a quake, and buildings and infrastructure would be more susceptible to damage, the bureau said.

Underground radioactive waste eyed for Chalk River

OTTAWA Enough nuclear waste to fill more than a hundred Olympic-sized swimming pools could be buried in an underground chamber near the Ottawa River, upstream from Parliament Hill and about a million residents of the nation’s capital.

The federal government is eyeing the site of the Chalk River nuclear reactor, 160 kilometres northwest of Ottawa, as a radioactive waste site.

Atomic Energy of Canada Ltd. says 267,000 cubic metres of low- and medium-grade nuclear waste is now stored above-ground in steel containers at the Chalk River site. The amount of radioactive material is expected to grow to 360,000 cubic metres by 2100. That’s enough debris to fill 106 Olympic swimming pools now, and 144 by the end of the century.

Government-owned AECL is looking at building an enormous underground repository to bury the detritus of six decades of nuclear testing at the Chalk River site. The cavernous compound would consist of shafts, access tunnels and as many as 223 storage rooms for the radioactive waste.
A document posted recently on a website that advertises government contracts outlines the proposal.

“Atomic Energy of Canada Limited is investigating the suitability of the Chalk River laboratories site for hosting a geologic waste management facility as part of the Nuclear Legacy Liabilities Program funded through Natural Resources Canada,” the document says.

“The (geologic waste management facility) is envisioned to be an underground engineered-geological repository consisting of shafts, access tunnels and emplacement caverns located at a nominal depth of 500 to 1,000 metres in the bedrock at the (Chalk River laboratories) site.”

Site studied for 6 years

AECL began looking at the Chalk River site as a nuclear burial ground six years ago. While the government has not yet decided where to bury the radioactive waste, Chalk River holds promise.
“No features have been found to disqualify the bedrock of the Chalk River laboratories site from hosting a GWMF,” the document says.

“The bedrock of the Chalk River laboratories site below a depth of 400 to 500 metres appears to have a good potential to safely host a GWMF for Chalk River laboratories’ (low- and intermediate-level radioactive waste) although the work to date is premature in nature.

“The many unknowns and uncertainties ... will need to be addressed as part of any future detailed siting-characterization process, if the government of Canada decides to initiate such a process.”
Ottawa Riverkeeper, a local conservation group, meets regularly with AECL to talk about the health and safety of the waterway. The group’s executive director, Meredith Brown, said there is always some chance radioactive material could leak into the Ottawa River.

“It’s always a concern,” Brown said.

“There’s always a chance (of a leak). I guess it depends largely on how they build it, right? I mean, obviously they’re going to have to built it to handle any seismic activity in the area. I take it that they know what they’re doing in that respect.”

Site in Earthquake zone

The proposed site is in the Western Quebec seismic zone, an earthquake belt that surrounds the Ottawa Valley from Montreal to the town of Temiscaming, Que., as well as the Laurentian mountains and parts of Eastern Ontario.

The AECL contract document notes the majority earthquakes in the area are very small, measuring between 2.0 and 4.5 in magnitude on the Richter scale.

However, the Natural Resources Department’s website says there have been at least three significant earthquakes there in the past. The most powerful occurred in 1935, when an earthquake measuring 6.2 on the Richter scale shook the Temiscaming area.

No one from AECL was available for an interview.

In an emailed statement, the Crown corporation said it would not make any decisions about where to store the waste without a full environmental assessment and public consultation.

“This is the first step in a long process designed to find a safe location for the long-term storage of low- and intermediate-level radioactive waste, which is already located at the Chalk River site,” the statement said.

“No decisions have been made by the Government to locate such a facility to (Chalk River laboratories); this (request-for-proposals) is a preliminary step to assess whether the site warrants continued consideration.

“AECL has completed a number of studies that investigate options for the long-term management of the legacy radioactive waste stored at the Chalk River site. AECL will continue to contribute expertise to support government decision-making regarding the infrastructure required to manage this waste inventory.”

The Crown corporation has long been a headache for successive federal governments. AECL has cost Canadian taxpayers billions of dollars and faced major cost overruns at key projects in recent years while struggling to find a buyer.

In May 2009, the Conservative government announced plans to spin off AECL’s commercial reactor business from its research division. The announcement coincided with what turned into a lengthy shutdown of the company’s Chalk River research reactor, which caused a worldwide shortage of the medical isotopes used to detect cancer and heart ailments.

The National Research Universal reactor was down for 15 months. There were times when it looked like the half-century-old reactor might never return to service.

An earlier shutdown in late 2007 also strained the global isotope supply and ended only after Parliament voted to bypass the nuclear safety regulator’s closure order.

The government finally sold AECL’s Candu nuclear reactor business to SNC-Lavalin in October for $15 million.

Since the sale of the reactor business, AECL has focused on its nuclear laboratories division, mainly in Chalk River and Pinawa, Man. The division, which has a staff of more than 3,000, manages nuclear waste, conducts research and produces medical isotopes.

74年Ontario的Building Code加入了抗震的要求，但之前的建筑需要担心， 包括楼上提到的核设施

曾经咨询过专门搞地球物理的同胞专家，说渥村应该是受自然灾害侵袭可能性最小的城市之一，俺才搬到这个村里的。

都说加州要迎来毁灭性地震，可是你看那个硅谷的房价啊，窜天猴一样地直冲云霄。

渥村比起那些地震带来，其实就是天堂啊。

“Canadian reactors routinely release radioactive tritium into the atmosphere and nearby bodies of water. All radiation releases increase risks of birth defects, cancer and other diseases. Tritium – radioactive hydrogen – is particularly dangerous because it can move readily as water to any cell in the body and accumulate in DNA; and it has just the right decay energy to damage DNA without killing the cell.”
