Waste Management, Decommissioning and Environmental Restoration Conference (Sep2011)

This conference, held in Toronto, ON, in Sep 2011, was organized by members of the division. The success of the conference can be attributed to a number of significant developments were reported on including the OPG DGR, the Port Hope Area Restoration Initiative, the assessment of feasibility of siting a geological disposal facility for LILW at CRL site, and the start of siting activities by the NWMO.

Interesting Plenary sessions on each morning of the Conference and 35 parallel technical sessions with over 130 final technical papers were well received by participants.

Waste Management, Decommissioning and Environmental Remediation Conference (May 2005)              

The conference organized by members of the division, held in Ottawa, ON, 2005 May, was successful with over 320 participants. Over 150 technical good quality papers (90% Canadian) were presented.

One plenary session (on waste classification systems) gave birth to a new national initiative through the Canadian Standards Association to come up with a Canadian standard to improve communication, reporting and joint planning. Another plenary session on waste clearance led to much better understanding all around of what future regulations may look like, and what the real-world implications of the requirements could be.

Update on the Nuclear Waste Management Organization’s (NWMO) Statement on Reconciliation

The NWMO’s Council of Elders and Youth, the Board of Directors, and NWMO leadership gathered together to finalize a Reconciliation statement through Indigenous ceremony.

The statement outlines the NWMO’s commitment to reconciliation and commits the organization to building relationships with Indigenous peoples and communities based on mutual respect and understanding.

This is a big step for NWMO; one that continues their journey since their founding.

NWMO has been clear as we work toward selecting a site for Canada’s used nuclear fuel that we can only move forward in partnership with local First Nation and Métis communities. Establishing that partnership includes acknowledging historical wrongs in Canada’s past, and clearly committing to reconciliation and working together to co-create a shared future built on rights, equity, and well-being for everyone.

The NWMO’s Reconciliation Statement is their acknowledgement and promise as an organization. The promise to continue that journey and to help build a better future by addressing the challenges of today is a milestone.

NWMO will be sharing some photos and a short video about the event on the NWMO’s Facebook and Instagram pages.

Environmental impact of nuclear power

From Wikipedia, the free encyclopedia 

The environmental impact of nuclear power results from the nuclear fuel cycle, operation, and the effects of nuclear accidents.

The greenhouse gas emissions from nuclear fission power are much smaller than those associated with coal, oil and gas, and the routine health risks are much smaller than those associated with coal. However, there is a “catastrophic risk” potential if containment fails,[1]which in nuclear reactors can be brought about by over-heated fuels melting and releasing large quantities of fission products into the environment. This potential risk could wipe out the benefits. The most long-lived radioactive wastes, including spent nuclear fuel, must be contained and isolated from the environment for a long period of time. On the other side, spent nuclear fuel could be reused, yielding even more energy, and reducing the amount of waste to be contained. The public has been made sensitive to these risks and there has been considerable public opposition to nuclear power.

The 1979 Three Mile Island accident and 1986 Chernobyl disaster, along with high construction costs, also compounded by delays resulting from a steady schedule of demonstrations, injunctions and political actions, caused by the anti-nuclear opposition, ended the rapid growth of global nuclear power capacity. A release of radioactive materials followed the 2011 Japanese tsunami which damaged the Fukushima I Nuclear Power Plant, resulting in hydrogen gas explosions and partial meltdowns classified as a Level 7 event. The large-scale release of radioactivity resulted in people being evacuated from a 20 km exclusion zone set up around the power plant, similar to the 30 km radius Chernobyl Exclusion Zone still in effect. But published works suggest that the radioactivity levels have lowered enough to now have only a limited impact on wildlife.[ In Japan, on July 2016, Fukushima Prefecture announced that the number of evacuees following the Great East Japan earthquake events, had fallen below 90,000, in part following the lifting of evacuation orders issued in some municipalities.
