# Terrestrial Energy
|
|
|
|
## Overview
|
|
Canadian advanced nuclear company developing the Integral Molten Salt Reactor (IMSR), a Generation IV reactor design using lithium fluoride-based fluoride salts as combined fuel and coolant.
|
|
|
|
## Technology
|
|
- **IMSR Design**: 822 MWth / 390 MWe capacity
|
|
- **Operating Temperature**: 600-700°C
|
|
- **Core Innovation**: Fluoride salts serve as both fuel carrier and coolant
|
|
- **Optional Grid Integration**: Can couple with external nitrate salt thermal storage for grid-scale energy buffering, enabling nuclear heat to recharge thermal batteries that complement wind/solar
|
|
- **Chemistry**: Uses lithium fluoride-based salts (distinct from CSP industry's sodium/potassium nitrate)
|
|
|
|
## Regulatory Progress
|
|
- **September 2025**: NRC approved IMSR Principal Design Criteria
|
|
- **April 23, 2026**: Submitted topical report on safety events to NRC—final stage before Safety Evaluation Report (SER)
|
|
- **Target**: Licensed commercial operation in early 2030s
|
|
- **Strategic Value**: An SER would allow the same safety determination to be referenced in multiple future licensing applications, enabling fleet-scale efficiency
|
|
|
|
## Timeline
|
|
- **2026-04-23** — Submitted foundational safety topical report to NRC, final step before Safety Evaluation Report
|
|
- **2025-09** — NRC approved IMSR Principal Design Criteria |
