Nuclear power plants are among the most demanding facilities from a security management perspective. The scale of installations, the number of monitored data points and the stringent regulatory requirements mean that a security system integration platform must meet challenges not encountered in any other type of facility.

In practice, this means handling thousands of data points, providing dedicated control mechanisms and supporting operators in making time-critical decisions. Below is a discussion of the key GEMOS environment features that address these requirements.
Automatic data point import from CAD files
A nuclear power plant is a facility where the number of monitored data points — sensors, detectors, controllers, input/output modules — reaches thousands, sometimes tens of thousands. Manually entering each one into the visualisation system would be not only time-consuming but also prone to error.
Automatic data point import from CAD files — thousands of elements placed on site plans without manual entry.
The GEMOS environment enables automatic data point import directly from CAD files. As a result, installation elements — together with their location on site plans — are transferred to the visualisation system in an automated manner, preserving the precision of the design documentation.
Data points imported from CAD documentation — each element retains its precise location on the facility plan.
This process significantly shortens system deployment time and minimises the risk of omitting or misplacing a data point. In the case of installation modernisation or expansion, updating the visualisation is reduced to re-importing the updated CAD file.
Dedicated functions — management in practice
The specifics of a nuclear power plant require the integration platform to offer functions that go beyond the standard scope of security system visualisation. One example is dedicated fire alarm control buttons that allow the operator to quickly perform key actions — such as confirming an alarm, silencing the acoustic signal or initiating an evacuation procedure for a selected zone.
Dedicated control buttons — quick access to key fire alarm system functions directly from the visualisation level.
These buttons are designed in cooperation with the facility’s technical staff so that their layout and logic correspond to actual operational procedures. In a heightened security environment, there is no room for accidental clicks — critical controls may therefore require additional confirmation or authorisation.

Operator support
In a nuclear power plant, every operator decision must be made on the basis of reliable information and in accordance with established procedures. The GEMOS environment supports this process by providing operators with technical documentation and response procedures directly in the context of an alarm event.
Documentation and response procedures accessible directly in the context of an event — the operator does not need to search external sources.
When an alarm occurs, the system can automatically display the response procedure assigned to the given event type and facility zone. The operator receives step-by-step instructions, minimising the risk of missing a critical action — particularly in stressful situations where time pressure is immense.

This is complemented by an event archiving module that records not only the alarms themselves but also the actions taken by operators — which is essential both for audit purposes and for refining procedures.
Ready for any integration
A nuclear power plant is a facility where, alongside classic security systems — such as fire alarm, access control and video surveillance — specialised systems operate, including ionising radiation monitoring systems.
Integration with radiation monitoring systems — data from ionising radiation detectors accessible in the visualisation environment.
Thanks to its open integration architecture, the GEMOS platform enables the inclusion of such systems in a shared visualisation environment. The operator has access to radiation detector data on the same site plans where fire sensor statuses, cameras and access control readers are displayed.
One site plan — all security systems, including radiation monitoring, accessible in a single view.
Readiness for integration with specialised systems is a feature that is of critical importance in the context of nuclear power plants. The integration platform must not only support a broad spectrum of communication protocols but also ensure an appropriate level of reliability and redundancy — commensurate with the importance of the protected facility.
