Uranium mining has been a significant industry in Saskatchewan since the s, when the major demand for the product was for the manufacturing of nuclear weapons. More recently, uranium is chiefly used for fuelling nuclear power reactors, in Canada, the United States, as well as overseas. Uranium ore is mined in northern Saskatchewan and milled there to create yellowcake before being shipped.   Canada has no national program to deal with contaminated sites. Abandoned mines and tailings ponds create toxic nightmares, contaminating rivers, lakes and surrounding lands. Local communities are left with the toxic legacy.” Saskatchewan uranium mines create toxic legacy, Digital Journal by Kyle Ashmead, 28 Aug , The Keepers of the Water, held a.

The Saskatchewan Environmental Society says more investigation should have been done on the feasibility removing the tailings. It questions how the covering will stand up as climate change delivers more severe weather, and whether government will continue to monitor the sites. From the s onward, a larger proportion of Saskatchewan’s uranium was mined for use in nuclear power plants. After almost half a century of mining, Saskatchewan uranium is used in almost every nuclear power reactor in Canada, the U.S., Japan, South Korea and Western Europe. Health and environmental effects.

This chapter presents a discussion of impacts of uranium mining and processing operations on air quality, soil, surface water and groundwater, and biota. Much is already known about the environmental impacts of mining, both on-site and off-site, and that body of information provides a basis for this chapter. However, the primary emphasis of the chapter is on the unique impacts caused by.   Article content continued. Perched on the north shore of Lake Athabasca, the Gunnar mine was abandoned in Work on the cleanup, which includes covering sprawling tailings .

Both sites are located in the Athabasca Basin region of Northern Saskatchewan. The McClean Lake site has been in operation since and includes a uranium mill and tailings management facility.

The Cluff Lake facility was shut down in and consisted of a uranium mine, mill, and tailings management area. environmental conditions of the Cold War Legacy Uranium Mine and Mill Sites in Northern Saskatchewan, which include s the rehabilitatio n of the former Gunnar mine and mill site.

Most uranium mine sites in northern Saskatchewan have tailings disposal facilities at them that pose a long term risk to the environment. In this paper we focus in on the Key Lake uranium mill site as a current example. At Key Lake the issue to consider is whether uranium mill tailings can be properly contained for thousands of years into the future.

The governments of Canada and Saskatchewan are now funding the clean-up of these abandoned northern uranium mine and mill sites and have contracted the management of the project to the Author: Laurier L.

Schramm. Mine and Mill Sites During the s and s, uranium mines and small prospecting sites were developed and operated across northern Saskatchewan by private companies. The sites and mining operations were later abandoned with little consideration to environmental protection or aesthetics.

SRC is remediating 37 abandoned uranium mine sites in northern Saskatchewan. Project CLEANS focuses on removing safety hazards and restoring the land. address the current environmental conditions of the Cold War Legacy Uranium Mine and Mill Sites in Northern Saskatchewan, which includes the rehabilitation of the former Gunnar site.

Under the MOA, Saskatchewan Industry and Resources (SIR) has been assigned the responsibility to ensure that the project is carried out on behalf of the two. Saskatchewan, feds at odds over abandoned uranium mine remediation WATCH: The Saskatchewan and federal governments are in dispute over the cleanup of abandoned uranium mines.

Most of the contamination dates back to the ‐ period when Eldorado Nuclear Ltd., a federal crown corporation, operated numerous mining properties east of Uranium City.

The moss bag technique of air quality monitoring has been used to assess the spatial distribution of metal particulates blown as dust from U tailings adjacent to the Lorado mill in northern Saskatchewan. Monitoring sites were set up at 32 locations on and around the tailings during June, July, and August, Of the 23 metals initially detected in the tailings by plasma emission spectroscopy.

The Saskatchewan Research Council (SRC) is working in northern Saskatchewan to remediate 37 abandoned uranium mine and mill sites as part of Project CLEANS (Cleanup of Abandoned Northern Sites). There are two licensed closed uranium mine and tailings sites in the Northwest Territories: Port Radium mine and Rayrock mine.

address the current environmental conditions at the abandoned uranium mine sites in northern Saskatchewan, including the Gunnar site. Under the MOA, the Saskatchewan Ministry of the Economy (ECON) is responsible for the remediation of the Gunnar site on behalf of the two governments.

The SRC was thereafter contracted by. Uranium tailings exist at operating uranium mill sites in northern Saskatchewan and at inactive or decommissioned sites in Saskatchewan, Ontario and the Northwest Territories. The following table provides a list of uranium mine and mill facilities licensed by the CNSC.

The evolution of tailings management in Saskatchewan’s uranium industry has come a long way since the initial mining of the Uranium City era.

The introduction of in-pit tailings management at Rabbit Lake in was the introduction of the current methodology. More than 50 years after a Saskatchewan uranium mill that is a key part of Canada’s nuclear history closed, heavy machinery is once again rumbling across the remote northern corner of.

The Saskatchewan Research Council (SRC) is proposing to rehabilitate the former Lorado Uranium mill site just north of Lake Athabasca.
