Nuclear Safety
Safety Principles
Three core principles guide every decision we make.
Defense in Depth
Our safety philosophy is built on defense in depth — multiple independent and redundant layers of protection, each designed to prevent, detect, or mitigate failures. No single barrier is relied upon for safety; instead, overlapping systems ensure that the failure of any one layer does not compromise overall protection.
- Robust fuel design and quality control
- Reactor coolant pressure boundary
- Containment structure
- Emergency response and mitigation
- Off-site emergency planning
ALARA Principle
All radiation exposures are kept As Low As Reasonably Achievable (ALARA), consistent with proper functioning of the plant and in consideration of economic and social factors. This principle drives continuous improvement in radiation protection practices across our operations.
- Time, distance, and shielding controls
- Continuous radiation monitoring
- Work planning and exposure optimization
- Regular employee training and awareness
- Annual ALARA performance reviews
Safety Culture
A strong safety culture is the foundation of nuclear safety. It encompasses the attitudes, behaviors, and organizational practices that ensure safety remains the overriding priority. We foster an environment where every individual feels empowered to raise safety concerns without fear of reprisal.
- Leadership commitment to safety
- Open communication and reporting
- Continuous learning and improvement
- Questioning attitude and peer checking
- Respectful and collaborative workplace
Multi-Barrier Containment
Radioactive material is contained by multiple independent barriers, each designed to prevent its release to the environment.
Fuel Matrix
Ceramic uranium dioxide pellets are designed to retain radioactive fission products within the fuel structure itself.
Fuel Cladding
Zirconium alloy tubes enclose the fuel pellets, forming the first physical barrier against the release of radioactive material.
Reactor Coolant System
The high-pressure reactor coolant boundary contains the radioactive coolant and prevents its release into the environment.
Containment Building
A reinforced, pre-stressed concrete structure with steel liner designed to contain any release of radioactive material under accident conditions.
Emergency Systems
Backup safety systems, including emergency core cooling and hydrogen management, provide additional protection during beyond-design-basis events.
Safety Performance
We track and report our safety performance across key indicators to drive continuous improvement.

Our Safety Culture
Our safety culture is built on the belief that every incident is preventable and every employee has the responsibility and authority to stop work if they observe an unsafe condition.
Integrity
We are honest and transparent about safety performance.
Accountability
Every individual is accountable for safety outcomes.
Vigilance
We maintain a questioning attitude at all times.
Continuous Learning
We learn from experience and share knowledge openly.
Standards & Regulations
Our operations comply with international safety standards and are subject to rigorous regulatory oversight.
IAEA Safety Standards
We align with the International Atomic Energy Agency's safety standards and conduct regular peer reviews.
National Regulatory Bodies
Our plants are licensed and inspected by the relevant national nuclear regulatory authority in each jurisdiction.
ISO Standards
Our management systems are certified to ISO 9001 (Quality), ISO 14001 (Environment), and ISO 45001 (Occupational Health & Safety).
WANO Membership
We participate in the World Association of Nuclear Operators, benefiting from peer reviews and best-practice sharing.
INPO Evaluation
Our U.S. plants are subject to evaluation by the Institute of Nuclear Power Operations.
NPT Treaty Compliance
We fully comply with all nuclear non-proliferation obligations and safeguards agreements.
