Empowering the future of energy through safe and innovative nuclear solutions that support decarbonization and energy resilience.

Supercharge tomorrow

With demand for sustainable energy rising globally, the challenge is delivering innovative solutions that drive meaningful progress while ensuring reliability and efficiency. By drawing on world-class expertise, we can support the advancement of nuclear projects in uranium mining & fuel processing, site selection, licensing, and permitting of new builds, support of existing nuclear plants and life extensions, and monitoring of on-going operations. WSP can also support decommissioning solutions and waste disposal - helping clients navigate complex transitions with confidence.

As countries look to new deployment of nuclear power with advanced and small modular reactors (SMRs), our specialists collaborate across borders, leveraging industry-leading research and global networks to develop solutions that are practical, scalable, and built for the future.

As we harness the potential of nuclear power, we act as stewards of innovation—supporting a cleaner, more sustainable future for generations to come. It is no small task, but when achieved, it’s a powerful force for progress.

Providing solutions at various phases of nuclear projects

Uranium mining & fuel processing

The nuclear lifecycle begins with the extraction and processing of uranium, a critical fuel source. This phase involves complex geological, environmental, and engineering considerations, and the development and construction of new fuel fabrication facilities. Drawing on decades of experience in mining, WSP has supported uranium projects across diverse geographies - helping navigate exploration, permitting, environmental assessments, and site closure. Our multidisciplinary approach reflects the integrated nature of mining and fuel preparation in the broader nuclear value chain.

Nuclear new builds

As countries explore new nuclear capacity, whether large-scale plants or small modular reactors (SMRs), the early stages of development hinge on navigating environmental approvals and regulatory frameworks. WSP has contributed to some of the most intricate nuclear projects in North America, the UK, Canada, and the Nordics, offering insight into both legacy infrastructure and emerging technologies. Our experience helps clients anticipate and address environmental and permitting challenges that shape the feasibility and timeline of new builds. As new build projects quickly move into construction, WSP is also a leader in providing services to deliver consistent quality, materials testing, and program management.

End-of-life planning & decommissioning

The final stages of a nuclear facility’s life require careful planning to ensure safety, regulatory compliance, and future land use. WSP works with licence holders to assess remediation and decommissioning strategies and evaluate opportunities for closure or redevelopment. Understanding the technical and environmental implications of end-of-life decisions is essential for long-term stewardship and community engagement.

Nuclear waste management

A sustainable nuclear future depends on robust strategies for managing radioactive waste. Deep geological repositories typically located 500 to 1,000 meters underground are the preferred solution for long-term containment. Since the 1970s, WSP has supported the development of these facilities, contributing to engineered barrier systems and site characterization across multiple continents. Our work informs policy, implementation, and research, helping stakeholders address one of the most critical challenges in the nuclear lifecycle.

Digital platforms

Our digital platforms perform a critical role in underpinning our advice and services. These world-leading tools allow us to collaborate across design teams, as well as with clients and the communities they serve; ultimately delivering stronger designs and advice.

Can Nuclear Small Modular Reactors (SMR) redefine our relationship with nuclear?

Our experts explore public perceptions of nuclear, why SMRs must be introduced differently and what the sector can learn from other energy sectors.

Frequently asked questions

What are some common challenges in new nuclear project site selection?

Site selection involves balancing technical, environmental, and social factors. Common challenges include:

Ensuring geological stability and low seismic risk
Access to grid infrastructure, water, and transport
Navigating complex regulatory requirements
Minimizing environmental impact
Building community and Indigenous support

WSP provides comprehensive site selection, site due diligence assessments and engagement strategies to help clients select viable, low-risk locations.

Small or large reactors – what should we consider in project development?

Choosing between Small Modular Reactors (SMRs) and large reactors depends on your goals:

SMRs:

Faster deployment (5–8 years)
Lower capital cost
Ideal for remote or industrial sites
Scalable and flexible

Large Reactors:

Higher power output (1,000+ MW)
Long-term baseload generation
Established regulatory pathways
Higher upfront investment but proven technology

WSP helps clients evaluate both options based on energy needs, site conditions, and long-term strategy.

How fast can new nuclear be deployed, and what are the power outputs and costs?

Deployment timelines and costs vary by technology:

SMRs: 5–8 years, 50–300 MW, $1–3 billion
Large Reactors: 10–12 years, 1,000–1,600 MW, $10+ billion

WSP supports clients with cost modeling, schedule planning, and risk mitigation to accelerate deployment and ensure financial viability.

How do you handle and dispose of nuclear waste?

Nuclear waste is managed through a tiered approach:

Low & Intermediate-Level Waste: Safely stored and disposed of in engineered facilities.
High-Level Waste (Spent Fuel): Initially stored on-site, then transferred to long-term geological repositories (or in onsite safe storage containers in the USA). The amount of nuclear waste generated is quite small – spent fuel that would be used to support the energy needs throughout the lifetime of one person that lived for 80 years would fit into a single soda can.

WSP provides services in waste characterization, facility design, transportation logistics, and regulatory compliance to ensure safe and responsible waste management.
