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
