DS Overview and Safety Functions
DS functions:
• Detritiation before gas release to environment
• Pressure Depression for dynamic confinement
• Filtration of radioactive particulates

DS Status
• DS core
– At early final design
• DS piping network
– Captive pipe installation begins 2021
• DS Qualification
– Technologies validated
– Beginning system qualification tests in 2021

Industrial Opportunities – TC-DS DS Design & Fabricate
• Scope
– Tokamak Complex Detritiation System (TC-DS) Core
• Total 8 modules (2 for normal operation; 6 standby for accident conditions)
• Planned contract for final design and procurement/fabrication of TC-DS Core
• Call for tender to be launched in 2021
• Final Design: 2022 - 2024
• Initial manufacturing and testing first components: 2024 – 2027
• Full manufacturing: 2025-2027

Industrial Opportunities – Other planned DS contracts
Other design & fabricate contracts planned as separate contracts:
• TC-DS Piping network (2023 – 2025)
– Approximately 8 km piping network connects clients to TC-DS Core
• Component Nuclear Qualification (2023 – 2025)
• Hot Cell Facility Detritiation System (HCF-DS)
– HCF-DS Core: 6 modules, similar arrangement to TC-DS
– HCF piping network similar scale to TC-DS piping network
– Will follow later according to Hot Cell Facility schedule
