Canadian Nuclear Laboratories (CNL) announced on November 9 that it has completed the excavation and transfer of about 450,000 cubic meters of historic low-level radioactive waste (LLW) and contaminated soils away from the Lake Ontario shoreline in Southeast Clarington, Ontario. The waste resulted from radium and uranium refining operations of the former Canadian Crown corporation Eldorado Nuclear and its private sector predecessors, which operated from the 1930s to 1988.

CNL said the placement of the last truckloads of waste in the aboveground mound at the new long-term waste management facility, located about 700 meters north of the shoreline site, marks a milestone for the Port Hope Area Initiative (PHAI), Canada’s cleanup and long-term management response to LLW in the municipalities of Port Hope and Clarington. CNL is implementing the PHAI on behalf of Atomic Energy of Canada Limited.

Work crews at the Department of Energy's Hanford Site recently completed removal and staging of 52 large concrete covers used to shield hoses for transferring radioactive waste between waste tanks in Hanford’s AY and AP farms. (Tank farms are groups of tanks.) The covers, known as “barns,” are being staged as part of an infrastructure improvement project until they can be used in the building of a hose system that will transfer waste from Hanford's A farm to the AP farm.

NRC proposes new LLW rule interpretation

March 9, 2020, 9:48AMNuclear News

The Nuclear Regulatory Commission is issuing a proposed interpretation of its low-­level radioactive waste disposal regulations that would permit licensees to dispose of waste by transfer to persons who hold specific disposal exemptions. The NRC said that it will consider approval of requests for specific exemptions only if they are for the disposal of very low-­level radioactive waste by land burial. Notice of the proposed interpretive rule was published in the March 6 Federal Register.
