Nuclear Power Plants and Radiation Technology

Nuclear power plants are complex facilities that use nuclear energy to generate electricity. They operate by splitting atomic nuclei, which releases a large amount of energy. This energy is then used to heat water and produce steam that drives turbines and thus generates electricity. Due to the way this energy is generated, radiation and radiation safety play a central role in the operation and monitoring of nuclear power plants.

Radiation Technology Products

Various radiation technology products are used to ensure both the safety of the facility and the protection of workers and the environment:

Radionuclide Identifiers (RID): These devices are crucial for identifying and quantifying radionuclides in the environment. They are particularly important in situations where a potential release of radioactive materials has occurred or is suspected.
Dosimeters: These instruments measure the dose of ionizing radiation to which a person has been exposed. They are crucial for protecting workers by ensuring that individual radiation exposure remains within legal and safety limits.
Dose Rate Meters: They measure the rate at which radiation dose is delivered, i.e., the dose rate. This information is important for monitoring areas within and outside the facility to ensure they are safely accessible.
Dose Rate Warning Devices: These devices are designed to trigger alarms when the radiation dose rate exceeds certain thresholds. They are an important part of the safety management in a nuclear power plant, as they allow for immediate warnings.
Contamination Detection Devices: These instruments are essential for detecting contamination of surfaces with radioactive substances. They play an important role in decontamination and in procedures to prevent the spread of radioactive materials.
Probes: Specialized probes are used to take samples of the environment or perform measurements in areas that are difficult for humans to access. They can also be used to identify specific types of radiation.
Telescopes: Telescopes used in radiation technology can serve to detect high-energy particles from cosmic sources or from the reactor itself. They are important for research purposes and for monitoring the natural radiation background.
Area Monitoring Monitors: These devices are constantly operated to monitor radiation levels in various areas of the facility. They help ensure that the work environment remains safe and that no unexpected events occur.

Each of these devices contributes in its own way to ensuring safety in nuclear power plants by enabling precise measurement, monitoring, and control of radiation. The continuous development and improvement of these technologies are crucial for further enhancing nuclear safety and ensuring the protection of people and the environment.

Area monitors GRAETZ WS05C

Simultaneous monitoring of up to 3 areas with any probes from the GRAETZ probe program
Up to 3 measuring channels
An illuminated LC display is assigned to each measuring channel, on which the measured values are displayed
When using gamma probes, the dose rate is shown on the LC display in Sv/h
When using end window probes (α-/β-measurements) or NaI scintillation probes (β-/γ-measurements), the measured value is displayed in Ips
For each channel 4 freely programmable dose rate warning thresholds in the entire measuring range of the respective connected gamma probe
The measuring range switchover within a channel takes place automatically. If a measuring channel triggers a dose rate alarm, both an optical and an acoustic warning is given at the WS05C by the integrated warning light column
In the standard version: Green for “Ready for operation”, Orange for “Warning threshold exceeded”, Red for “Error message” (e.g. probe failure).
Red LED above the display indicates which measuring channel has triggered an alarm
An RS-232 interface is available for connecting a measuring channel to a PC

Optional:

Relay output for controlling an additional external optional warning light column for each measuring channel
Potential-free relay output for each measuring channel (switching capacity max. 24 V, 20 mA)
Acoustic alarm with triggered warning threshold occurs when the door to the monitored room is open, a motion detector or a light barrier has been activated
Counter for irradiation time
Operating hours counter
Rotating beacon
Integration of already existing warning devices
External warning light columns (optical/acoustic)
Probe cable, extension up to 100 m (standard length: 1.25 m)
Emergency power supply (300 W) for uninterrupted operation of WS05C in case of power failure
Special designs possible on request
