Refurbishment of the Spent Fuel Pool

The project consists of determining, testing and qualifying a radiation resistant membrane, then installing the flexible waterproof qualified protective liner on the existing deteriorating pool walls in a highly radioactive environment (spent fuel in pool) using mechanical metal fixtures.

Third Party Expert Review of Reactor Components Inventory

This project consists of providing a third-party expert review and a detailed calculation of the core components inventory in preparation for the decommissioning plan.

Spent Fuel Storage Structures (CANSTOR) Investigation

CANSTOR is a spent fuel reinforced concrete storage structure in which seven years cooled spent fuel S.S. baskets are stored dry for a period of 50 years. This project consists of investigating the existing structures in which water has been repeatedly detected during sampling campaigns, and providing solutions and recommendations.

Spent IX Resins Extraction, Dewatering and Dry Storage

This project consists of removing wet radioactive spent resins from two underground full 170 m³ capacity rectangular concrete reservoirs by slurrying the resins into 3 m³ S.S. containers within a shielded flask and subsequently dewatering them for dry storage on the on-site solid radioactive waste facility.

Moderator D20 - Intermediate Storage Options Assessment after Shutdown

This project consists of assessing multiple options for 40 years storage of the highly tritiated moderator heavy water or to dispose of it off-site immediately.

Expertise and technical support for the corrective work to be performed on the reactor building ring beam

This project consists of performing an assessment of the current condition of the ring beam of the reactor building and implement urgent corrective work to secure the structure before the winter.

Turnkey Retrieval and Packaging of Spent IX Resins

This turnkey project consists of providing all services and operation staff related to performing recovery and packaging of the spent resin waste from two underground horizontal S.S. cylindrical storage tanks, through a restrictive 10” access pipe, into 5 m³ High Integrity Containers (HIC) within appropriate certified transportation shielded casks, for processing and dry storage.

Turnkey Retrieval and Packaging of Spent IX Resins

This turnkey project consists of providing services and operation staff related to sampling and characterization, recovery, packaging into drums, and shipment of the Moderator Purification System (MPS) resin waste stored in an underground horizontal S.S. cylindrical storage tank, and Heat Transport Purification System (HTPS) resin waste stored in four underground rectangular concrete storage vaults, as well as associated mixed water, sand, and gravel waste for interim storage.

Turbine and Auxiliary Systems Sampling Characterization

This project consists of retrieving multiple physical samples from the turbine and auxiliary systems and analyzing them for contamination in order to plan for this system’s decommissioning.

Study and Options Assessment of Low- Intermediate- and High Level- Waste Disposal from Power Plant Auxiliary Pools

This project consists of a preliminary assessment on the inventory, handling and disposal of all low-, intermediate-, and high-level wastes stored in the four auxiliary pools, after the power plant’s definitive shutdown. The objective is to optimize the waste streams and maximize the use of existing shielded handling equipment and storage structures.

Processing, Transfer and Disposal of Low and Intermediate Level Waste from Power Plant Auxiliary Pools

This project consists of developing the methodology and tooling required to transfer all miscellaneous low and intermediate level waste from the storage bays to interim dry storage structures. Most of the waste consisted of filters used to recuperate debris within the pool.

Processing, Transfer and Disposal of High-Level Waste from Power Plant Auxiliary Pools

This project consists of developing the methodology and tooling required to transfer all miscellaneous high-level waste from the storage bays to interim dry storage structures, including modification of the existing unused concrete structures to receive this waste.

Fabrication of Spent Fuel Shielded Interface Modules

This project consists of fabrication of key shielded interface components for the loading and unloading of CANDU spent fuel baskets for relocation to centralized interim storage facility.
