Fermi Unit 2 FWH Replacement
Project Highlights
- Sargent & Lundy is supporting DTE through all phases of project by working closely with stakeholders, implementation team and vendors.
- New No. 4 and No. 5 FWH fabrication complete and delivered to Fermi 2.
Project Description
The Fermi 2 North and South No. 3, No. 4 and No. 5 low pressure FWHs are approaching end-of-life and have experienced a reduction in thermal performance and age-related degradation, resulting in numerous condition reports over the last several years.
Project Scope
DTE has contracted Sargent & Lundy to complete the design work for all phases of the project associated with replacing the North and South No. 3, No. 4 and No. 5 FWHs (e.g., study, purchase specifications, modification packages, fabrication support). The No. 5 FWHs are being designed to submerge tubes in the condensing zone to provide subcooling to prevent drain line flashing in future power maneuvers. This replacement scope includes all piping rerouting/modifications associated with relocation or reconfiguration of the replacement FWH nozzles, as well as temporary removal or permanent resolution of interferences (piping, equipment, etc.) in the removal and installation path of the FWHs. Additionally, the small-bore vent and drain lines experiencing leakage concerns will be redesigned to incorporate dual isolation globe valves to ensure proper isolation.
