CNSC regulatory documents

The NSCA and its associated regulations provide the basis for regulatory expectations and decisions. Regulatory documents clarify NSCA require­ments and associated regulations, and are an integral part of the regulatory framework for nuclear activities in Canada. Each regulatory document aims to disseminate objective regulatory information to stakeholders, including licensees, applicants, public interest groups and the public, and promote consistency in the interpretation and implementation of regulatory require­ments. As outlined in the CNSC Regulatory Policy P299, Regulatory Fun­damentals (CNSC, 2005), CNSC sets requirements using appropriate industry, national and international standards. The CNSC regulatory frame­work draws upon Canadian and international standards and best practices, including the nuclear safety standards of the International Atomic Energy Agency (IAEA).

A list of CNSC’s regulatory documents is available online at: nuclearsafety. gc. ca. Two of these documents are specific to the management of RAW. Other more generic regulatory documents that relate to action levels, decommissioning, environmental protection and public information programs may also apply to the management of RAW. The CNSC’s regulatory documents for management of radioactive waste are discussed below.

The CNSC Regulatory Policy P-290, Managing Radioactive Waste (CNSC, 2004) outlines the philosophy and principles used by the CNSC in regulat­ing radioactive waste. The policy considers the extent to which owners of RAW must address:

• waste minimization;

• the radiological, chemical and biological management of RAW;

• the predicted impacts on the health and safety of persons and the environment;

• the measures needed to prevent unreasonable risk to both present and future generations; and

• the trans-border effects on the health and safety of persons and the environment.

The CNSC Regulatory Guide G-320, Assessing the Long Term Safety of Radioactive Waste Management (CNSC, 2006) assists licensees and applicants to assess the long-term storage and disposal of RAW. The guide was developed using provincial, federal and international documents, fol­lowing a consultation with the nuclear industry in Canada.

In addition, the nuclear industry in Canada, in conjunction with the CNSC, has developed two Canadian Standards Association (CSA) stand­ards for the interim management of used nuclear fuel and RAW. These standards incorporate best practices both nationally and internationally. For example, the CSA has developed a standard consisting of best practices for the safe siting, design, construction, commissioning, operation and decom­missioning of facilities and associated equipment for the dry storage of irradiated fuel, known as CSA N292.2-07, Interim Dry Storage of Irradiated Fuel. (CSA, 2007). The standard CSA N292.3-08, Management of Low — and Intermediate-Level Radioactive Waste (CSA, 2008) provides advice on the management of low — and intermediate-level radioactive waste which is based on current best practices, international experience and guidance, and in accordance with the existing CNSC regulatory requirements.
