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 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.

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.

Job description

Idaho National Laboratory is hiring a well-qualified Postdoctoral Research Associate to perform laboratory-based research and development of electrochemical systems and processes within our Chemical Separations group in the Critical Materials and Geothermal Energy Department. Our team works a 9x80 schedule located out of our Idaho Falls facility with every other Friday off. You will report to the Project Investigator.

You will develop and optimize electrochemical systems for a variety of pyrometallurgical/molten salt applications including metallic deposition, electrochemical redox stripping, electrophoretic separations, leaching and electrochemical processing. Knowledge and a working background in electrochemical processes in moderate and high temperature molten salt systems in inert environments is required.

Responsibilities:
  • You will be a strong asset to an established R&D team to achieve specific project/program targets and goals on multiple projects within the same area of study.
  • Autonomous work and collaborative work taking direction from other team members and peers.
  • Writing scientific manuscripts for journal publication, project reports and proposals, as well as preparing presentations of research results and presenting them at national/international conferences/workshops/meetings.
  • Must maintain currency in relevant scientific literature, meet Environment Safety and Health (ES&H) goals, demonstrate a strong commitment to safe laboratory practices, and perform all work in an environmentally safe and compliant manner.
Required:
  • Ph.D. in Engineering, (e.g., chemical engineering or nuclear engineering (with emphasis on electrochemical studies) or Ph.D. in Physical Sciences (e.g., chemistry, or materials science, or physics).
  • PhD requirements must be completed by commencement of appointment and within the previous 5 years.
  • A developing publication record with demonstrated oral and published written communication skills (in English).
  • Demonstrated experience in molten salt electrochemistry, electrodeposition of metals, from fundamental understanding of reduction/nucleation processes to electrochemical engineering and process optimization and production of electrodeposits with desirable composition and material properties.
  • Hands‑on experience with inert‑atmosphere gloveboxes.
  • Experience with electroanalytical (CV, CA, CP, EIS) and surface characterization (XRD, SEM) techniques.
The ideal candidate will possess:
  • Experience in either electrocatalysis, spectro-electrochemistry, or computational/theoretical analysis.
  • Experience in molten salt electrolytic cell design.
  • Experience with high vacuum systems
Physical Requirements:

While performing the duties of this classification, the employee is frequently required to stand, walk, sit, stoop, kneel, bend, and work in an office and field/laboratory environment. The job requires hand/finger dexterity to keyboard or type, handle materials, manipulate tools, and reach with hands and arms. The job requires operation of job-related equipment. The employee must occasionally move up to 50 pounds using carts/dollies to move equipment into place. Sufficient visual acuity and hearing capacity to perform the essential functions and interact with people is required. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.

Job Information:
  • The pay for this position is $105,144.00 Annually. At Idaho National Laboratory compensation decisions are determined using factors such as education, relevant experience, and other credentials.
