Coal 2 Nuc proxy study for the retrofit of existing power asset with SMR

The Challenge

As part of its decarbonization strategy, the client sought to assess the feasibility of retrofitting an existing coal and biomass power plant with Small Modular Reactors (SMRs). The objective was to explore whether SMRs could serve as a viable low-carbon alternative while leveraging existing infrastructure. The challenge was to evaluate technical compatibility, regulatory constraints, and economic viability—without committing to a specific vendor or technology at this early stage.

The Solution

Tractebel conducted a comprehensive feasibility study to identify potential red flags and map out integration pathways for SMRs. The scope included defining suitability requirements and decarbonization scenarios, down-selecting best-in-class SMR designs, and conducting a pre-siting assessment aligned with IAEA NS-R-3 standards. The study also covered project roadmapping, cost assessment, and technical integration, including thermodynamic modeling to evaluate heat recovery and system compatibility. Tractebel’s approach combined international benchmarking with in-house nuclear expertise to deliver a robust and vendor-neutral analysis.

The Impact

The study provided the client with a clear path forward, quantifying the reusability of existing infrastructure and identifying the most promising SMR technologies for retrofit. By establishing a solid technical and economic foundation, Tractebel enabled informed decision-making and de-risked early-stage planning. This mission highlights Tractebel’s leadership in nuclear innovation and its commitment to supporting the energy transition through practical, future-ready solutions.
