CANSTOR is a spent fuel reinforced concrete storage structure in which seven years cooled spent fuel baskets are stored dry for a period of 50 years. This project consists of investigating the existing structures in which water has repeatedly been detected during sampling campaigns and providing solutions and recommendations.
Timeframe: 2013/2015
This project consisted of investigating the existing structures in which water has repeatedly been detected during sampling campaigns and providing solutions and recommendations.
The main activities provided are:
- Perform preliminary investigation to identify potential causes of water infiltration and propose a test program to confirm the cause
- Prepare the detail testing plan and procedure for the leak and pressure testing to be performed on the fully spent fuel loaded cylinders
- Expert confirmation of the cause of water presence post-tests
- Recommend modification to the spent fuel basket loading into the structures to eliminate water presence reoccurrences in subsequent cylinders
- Propose a solution to reduce/eliminate water/humidity in fuel loaded cylinders
- Prepare technical specification for the supply of an efficient drying system to completely eliminate residual water/humidity within affected cylinders
- Provide technical support for procurement and testing of the drying system.
