Canada’s Radioactive Waste Policy Framework

In accordance with Canada’s Radioactive Waste Policy Framework the waste producers and owners of radioactive waste are responsible for the funding,

• rganization, management and operation of disposal and other facilities required

for their wastes. Responsible nuclear waste management includes full life cycle management from generation to disposal. CNL and AECL are working actively at strategic and operational levels to identify strategies and solutions for waste management of the entire life cycle of all radioactive waste classifications including low level waste, intermediate level waste and high level waste.

Classification of radioactive waste

IAEA General Safety Guide (GSG)‐1, Section 2.27 … A limit of 400 Bq/g on average (and up to 4000 Bq/g for individual packages) for long lived alpha emitting radionuclides has been adopted in some States. For long lived beta and/or gamma emitting radionuclides … the allowable average activity concentrations may be considerably higher (up to tens of kilobecquerels per gram). Canadian Standards Association (CSA) N292.0‐19, A.5.1 …a limit of 400 Bq/g on the average (and up to 4000 Bq/g for individual waste packages) for long‐lived alpha emitting radionuclides can be considered in the classification process. For long‐lived beta and/or gamma emitting radionuclides … the allowable average activity concentrations can be considerably higher (up to tens of kBq/g).

• Historic waste information was used to populate the NSDF

Inventory.

• Nonetheless, the NSDF Reference Inventory does not qualify any

specific materials for disposal.

• All waste destined for NSDF will be evaluated against all of the

requirements of the licensed NSDF.
