Despite their advantages, there are several challenges associated with the use of modular reactors:
1. Cost: The initial investment for modular reactors can be high, although it is often offset by the long-term benefits. 2. Complexity: The design and operation of modular reactors require specialized knowledge and skills. 3. Scalability Limitations: While modular reactors are scalable, there can be challenges in translating lab-scale results to industrial-scale production.
