Triso information
What are some common challenges faced by professionals working in the TRISO fuel industry, and how can job seekers prepare for them?
What is the difference between Triso vs Radiologic Technologist?
| Aspect | Triso | Radiologic Technologist |
|---|---|---|
| Required Credentials | Certification in Triso procedures, relevant healthcare certifications | ARRT certification, state licensure |
| Work Environment | Hospitals, clinics, specialized imaging centers | Hospitals, outpatient imaging centers, clinics |
| Industry Usage | Medical imaging, diagnostic procedures | Medical imaging, diagnostic radiography |
| Common Search/Comparison | Yes | Yes |
While Triso specialists focus on specific imaging procedures involving Triso technology, Radiologic Technologists perform a broader range of diagnostic imaging tasks using various radiographic equipment. Both roles require certification and work in similar healthcare environments, but Triso is more specialized within the imaging field.

Job description
About Valar Atomics
At Valar Atomics, we're redefining what's possible in energy. Our mission is to make clean, high-temperature nuclear power scalable-unlocking abundant energy for industry, hydrogen, and next-generation manufacturing. We are a team of builders, engineers, and operators who believe nuclear energy should be fast to deploy, factory-made, and built for the real world. Our first pilot plant in Orangeville, Utah will demonstrate how advanced nuclear systems and fuel fabrication can power the future. Joining Valar Atomics means becoming part of a company where autonomy, ownership, and impact exist at every level.
The Role
We're looking for a Plant Operator who thrives on challenge and precision-someone ready to help commission and operate one of the most advanced energy and fuel systems ever built. This role begins with an intensive onboarding and training period at Valar Atomics' headquarters in Los Angeles, where you'll work directly with our design, controls, and engineering teams before relocating to the Utah pilot site. Operators may be assigned to either the reactor plant or the pilot fuel fabrication facility, depending on operational needs and experience. At Valar, we take a team-first approach-everyone pitches in to tackle the most critical tasks, no matter the title. Whether it's assisting with commissioning, troubleshooting, or hands-on plant work, you'll be part of a tight-knit team that values collaboration, adaptability, and a shared commitment to the mission.
Key Responsibilities
- Operate and monitor advanced high-temperature reactor systems and/or pilot TRISO fuel fabrication equipment.
- Execute startup, shutdown, and routine operations in accordance with safety and procedural standards.
- Work hands-on with engineering teams during commissioning, testing, and performance validation of both reactor and fuel systems.
- Analyze operational data to identify trends, optimize efficiency, and maintain system reliability.
- Support process control, material handling, and quality assurance for fuel fabrication operations.
- Collaborate across teams to refine procedures and contribute to a culture of continuous improvement.
- Uphold Valar's safety, environmental, and quality commitments every day.
You Will Be Successful in This Role If
- You're technically strong, detail-driven, and calm under pressure.
- You're energized by hands-on work and real-world problem-solving.
- You take ownership in a fast-moving environment and are eager to learn and grow.
- You're a team player who values shared goals and steps in wherever needed.
- You hold a high bar for safety, procedural discipline, and quality.
- You communicate clearly with engineering and operations partners and surface issues early.
Basic Qualifications
- Associate degree or equivalent training in nuclear technology, mechanical, chemical, or electrical systems.
- 2+ years of experience in industrial, power plant, or process operations.
- Strong understanding of safety culture, technical systems, and control instrumentation.
- Willing to relocate temporarily to Los Angeles for training, and then to Orangeville, UT for ongoing operations.
Preferred Skills and Experience
- Background in nuclear operations (commercial, research, or naval) or fuel fabrication processes.
- Familiarity with TRISO fuel systems, helium coolant loops, or high-temperature process systems.
- Experience with commissioning, plant startups, chemical processing, or control room operations.
Equal Employment Opportunity Statement
Valar Atomics is an equal opportunity employer. We consider all qualified applicants without regard to race, color, religion, sex, gender identity, sexual orientation, national origin, age, disability, veteran status, or any other protected status under applicable law.
We are committed to providing a workplace free of discrimination and harassment and will provide reasonable accommodation as required by law.
