Canadian Joint Review Panel Recommends the Approval of the DGR Project

In January 2012, a Joint Review Panel was appointed by the federal Minister of the Environment and the President of the Canadian Nuclear Safety Commission (CNSC). It was mandated to assess the environmental effects of Ontario Power Generation's project for the development of a proposed Deep Geologic Repository (DGR) for low and intermediate level radioactive waste at the Bruce nuclear site, Ontario. The Panel was also mandated to obtain the information required for the consideration of the Licence to Prepare a Site and Construct the project. On 6th May 2015, the Panel submitted its Environmental Assessment (EA) Report to the Canadian federal government ... Full Details

Concepts for Handling Norwegian Spent Nuclear Fuel and other Radioactive Waste

Quintessa has contributed to the successful completion of a concept selection study (KVU) for an intermediate store for spent nuclear fuel and other long-lived radioactive waste in Norway. The study was undertaken for the Norwegian Ministry of Trade, Industry and Fisheries by DNV GL AS and its partners Studsvik Nuclear AB, Quintessa Ltd., Westinghouse Electric Sweden AB and Samfunns- og Næringslivsforskning AS (SNF).

The study recommended sending all used Norwegian spent nuclear fuel abroad to be stabilised (reprocessed). In this case, Norway would receive a ... Full Details

The conference was organised by ONDRAF/NIRAS (Belgium) in cooperation with Andra (France), COVRA (The Netherlands), Nagra (Switzerland), NWMO (Canada), Posiva (Finland) and SKB (Sweden). Clays are exploited in most geological disposal concepts for radioactive waste, either as the host rock or as material for engineered barriers. The natural characteristics of clays ... Full Details

Long-Term Cement Studies Meeting in Henley-on-Thames

Quintessa recently hosted the biannual meeting for the Long-Term Cement Studies (LCS) project at Leander Club in Henley-on-Thames. This international project is a collaboration between Nagra (Switzerland; the project leaders), JAEA (Japan), Posiva (Finland), RWM (UK) and SKB (Sweden), and seeks to extend our understanding of cement and cementitious systems in the context of geological disposal of radioactive waste.

The historic Leander Club, one of the oldest rowing clubs in the world, provided a comfortable backdrop to the technical ... Full Details
