Document description

Licensees possessing nuclear material (uranium, thorium, and plutonium) are required to report their holdings, and any inventory changes, to the Canadian Nuclear Safety Commission (CNSC). The CNSC uses these reports to establish a national system of accounts for nuclear material.
This document:

• Ensures consistency in record-keeping and reporting of nuclear material, in accordance with Canada’s international obligations.
• Sets out the requirements for accurate and standardized accountancy of nuclear material inventories and describes the reporting requirements of nuclear material.

RD-336 supersedes AECB 1049 Reporting Requirements for Fissionable and Fertile Substances.

Where reporting of uranium, thorium and plutonium is currently required, licences refer to AECB 1049. In the fall of 2010, CNSC will be seeking Commission approval to amend these licences to reflect the new reporting requirements. Affected licensees will be contacted by their licensing officer regarding the proposed amendment. If they require additional information, affected licensees should contact their licensing officer.

Guidance document GD-336 Guidance for Accounting and Reporting of Nuclear Material has also been developed and will be published at the same time as RD-336. It provides supplementary materials for RD-336, including reports, forms, instructions, and reference tables.
