The phrase "a reactive system" is correct and usable in written English.
It can be used in contexts related to technology, software, or systems that respond to changes or inputs dynamically.
Example: "In modern software architecture, a reactive system can efficiently handle user requests and adapt to varying loads."
Alternatives: "an adaptive system" or "a responsive system".
The authors write:[T]he focus on preventive services is a profound shift from a reactive system that primarily responds to acute problems and urgent needs to one that helps foster optimal health and well-being.

The system proposed realizes a reflexive motion to bend the arm toward the target direction by detecting a contact location using a mechanical reactive system.
The bilayers were deposited using non-balanced magnetrons in a PVD reactive system in both a conventional manner and injecting extra N2 directly between the target and the substrate.
