Radiation Protection Engineering Support Services Project

Design Packages for Deep Geological Low and Intermediate Level Radioactive Waste Repository
Project Objective
The main purpose of the project was to support the consolidation of Radiation Protection (RP) requirements into interim design packages for the Deep Geological Repository (DGR) for low and intermediate level radioactive waste (L&ILW) in three areas:
  • Surface facilities;
  • Underground facilities and geotechnical; and
  • Hoist, headframes and shafts. 
Scope of Work
  • Prepare the RP program document to support the progression of the DGR design to the 50% and 80% milestones.
  • Provide support to design engineers and review design packages.  
  • Participate in the Constructability, Operability, Maintainability and Safety (COMS) review
  • Perform shielding calculations (using the point-kernel approach) and assess shielding designs to support the DGR design.
  • Perform detailed shielding analysis of potential design changes using the Monte Carlo N-Particle (MCNP) code to capture the irregular geometries involved. 
Solutions and Work Performed
 
This project was awarded to Candesco because of our experienced team members who are well-versed in RP programs for diverse nuclear facilities and have expertise in Occupational Health Physics. Additional Subject Matter Experts including a Certified Health Physicist, and analysts were engaged to provide specialized support and advice to ensure quality deliverables are produced.
 
Our team worked closely with design engineering firms experienced in the design of underground facilities, but less familiar with the requirements for radiation protection and the design of nuclear facilities. 
 
Results and Benefits for the Client

  • Project was completed on schedule and budget
  • Project had open lines of communication between the Candesco and NWMO technical staff, and the deliverables were successfully completed so that NWMO could progress the DGR design to the 50% and 80% milestones.
  • The scope of work was completed according to NWMO's Quality Plan
  • The RP program document was of high quality and met CNSC regulatory requirements as well as OPG's practices and procedures.
