CSA N288.7-15

1.1.1.1 This Standard addresses the design and operation of GWPPs for Class I nuclear facilities and uranium mines and mills. Notes: 1) In this Standard, any type of Class I nuclear facility and uranium mine and mill (refer to the definition of nuclear facility in Clause 3.1) is included in the term “nuclear facilities”. 2) Conventional waste management facilities on a Class I nuclear facility (or uranium mine and mill) are included in the scope of this Standard. 3) The applicability and suitability of this Standard to nuclear facilities will require professional judgment, knowledge of the relevant geological and hydrogeological conditions (e.g., travel time, position of freshwater aquifers, etc.), and validation of the CSM. For example, due to the potentially different environment encountered at great depths, portions of this Standard are likely not applicable to all aspects of deep subsurface facilities. Groundwater protection for such Class I facilities will be assured in the permitting and licensing process, and portions of this Standard can be used as applicable. 4) Not all Class I nuclear facilities and uranium mines and mills will need a GWPP. See Clause 5 on criteria for establishing a GWPP. 1.1.1.2 This Standard may also apply to the design and operation of GWPPs for a) Class II nuclear facilities; and b) facilities that use or store naturally occurring radioactive materials. Note: In these situations, however, the operator of the nuclear facility is responsible for determining the applicability and suitability of this Standard in consultation with the AHJ. 1.1.2 Facility lifecycle This Standard addresses monitoring performed during a) baseline characterization; b) site preparation, construction, and commissioning; c) operations; d) refurbishment or restarting after a prolonged shut-down; e) decommissioning; and f) post-decommissioning prior to abandonment and institutional control. Note: The nature and extent of groundwater monitoring requirements change over the lifecycle of the facility.
