How much do molten salt jobs pay per hour?

As of Aug 10, 2026, the average hourly pay for molten salt in the United States is $16.01, according to ZipRecruiter salary data. Most workers in this role earn between $13.22 and $17.31 per hour, depending on experience, location, and employer.

What is a molten salt worker?

Molten salt workers are professionals who operate, monitor, and maintain systems that use molten salt, typically in industrial settings such as energy generation (especially molten salt reactors or concentrated solar power plants), chemical processing, or metallurgy. Their responsibilities include handling the safe transfer and storage of molten salt, maintaining equipment at high temperatures, and ensuring compliance with safety protocols. These workers require specialized training due to the unique properties and hazards associated with molten salts, such as high temperatures and corrosiveness.

What are the typical responsibilities of an engineer working with molten salt systems in the energy sector?

Engineers working with molten salt systems, especially in the energy sector, often focus on designing, operating, and maintaining thermal storage or reactor systems that use molten salt as a heat transfer or storage medium. Daily tasks may include monitoring system performance, managing safety protocols, troubleshooting equipment issues, and collaborating with multidisciplinary teams such as chemists and process engineers. Due to the unique properties of molten salts, engineers must also address challenges like corrosion, material compatibility, and temperature control to ensure efficient and safe operation. This role offers opportunities to contribute to innovative renewable energy solutions and advance in specialized technical or leadership positions.

What is the difference between Molten Salt vs Nuclear Reactor Technician?

AspectMolten SaltNuclear Reactor Technician
Required CredentialsTechnical training, safety certificationsRadiation safety, reactor operation certifications
Work EnvironmentHigh-temperature molten salt systems, labs, research facilitiesNuclear power plants, reactor control rooms
Industry UsageResearch, energy storage, advanced reactor designsOperational nuclear power plants, maintenance

While both roles involve working with nuclear-related technologies, Molten Salt specialists focus on handling and researching molten salt systems used in energy storage and advanced reactors, whereas Nuclear Reactor Technicians operate and maintain existing nuclear reactors. The skills and certifications overlap in safety and technical knowledge, but their work environments and specific responsibilities differ significantly.

What are the key skills and qualifications needed to thrive as a molten salt engineer, and why are they important?

To thrive as a Molten Salt Engineer, you need a strong background in chemical engineering, materials science, or nuclear engineering, often with a relevant bachelor's or master's degree. Familiarity with process simulation software, corrosion testing equipment, and safety protocols for handling high-temperature materials is essential. Strong problem-solving skills, attention to detail, and effective teamwork are crucial soft skills in this role. These competencies ensure safe, efficient operation and innovation in molten salt systems, which are vital for applications like energy storage and advanced nuclear reactors.

Job description

Navarro Research and Engineering is recruiting a Mechanical Piping Engineer (3917) in Oak Ridge, TN. 

Navarro Research & Engineering is an award-winning federal contractor dedicated to partnering with clients to advance clean energy and deliver effective solutions for complex challenges in the nuclear and environmental fields. Joining Navarro means being a part of an exceptional team committed to quality and safety while also looking for innovative strategies to create value for the client's success. Headquartered in Oak Ridge, Tennessee, Navarro has active programs in place across the nation for DOE/NNSA, NASA, and the Department of Defense. 

Position Summary 

The Mechanical Piping Engineer will support the design and integration of high-temperature piping systems associated with custom process equipment, molten salt systems, furnace systems, and related industrial equipment. This role will develop safe, reliable, and maintainable piping solutions while coordinating closely with mechanical equipment, process, electrical, controls, fabrication, and operations teams. 

Responsibilities 

  • Design and support high-temperature piping systems, piping layouts, pipe supports, expansion features, connections, and equipment interfaces. 
  • Develop piping specifications, design criteria, calculations, material selections, drawings, isometrics, and technical documentation for custom process systems. 
  • Evaluate thermal expansion, material compatibility, insulation, routing, support loads, maintainability, safety, and fabrication constraints. 
  • Coordinate piping design requirements with high-temperature vessels, furnaces, electrochemical systems, instrumentation, controls, electrical power, and facility interfaces. 
  • Support design reviews, procurement, vendor coordination, fabrication, installation, testing, commissioning, troubleshooting, and configuration control activities. 
  • Identify piping design risks, interface conflicts, constructability issues, and technical constraints that may affect safety, reliability, cost, or schedule. 

Requirements

Requirements 

  • Experience with mechanical piping design for high-temperature process systems, industrial equipment, chemical processing, molten salt systems, or similar applications. 
  • Strong understanding of piping design principles, pipe routing, supports, thermal expansion, materials, insulation, design documentation, and equipment interfaces. 
  • Ability to support multidisciplinary engineering packages and coordinate technical requirements with design, fabrication, installation, and operations teams. 
  • Experience applying applicable piping codes, standards, quality requirements, safety expectations, and documentation controls. 
  • Ability to work in a complex technical environment requiring careful coordination, practical solutions, and strict attention to safety and quality. 

Preferred Qualifications 

  • Experience with molten salt piping, high-temperature metallic or specialty materials, furnace interfaces, or advanced energy process systems. 
  • Experience with pipe stress considerations, thermal growth management, specialty valves, heat tracing, insulation, or custom fabricated piping assemblies. 
  • Experience supporting DOE, NNSA, nuclear, laboratory, chemical process, or highly regulated industrial facility projects.
