Monitoring and determination of Beryllium contamination at HELCZA

摘要

Application and optimization of a method for quantification of beryllium dust particles present a key issue within the experimental complex HELCZA. The selected available analytical instrument is the portable fluorimetry by using a procedure ensuing from the NIOSH (National Institute for Occupational Safety and Health) method. The experimental complex HELCZA is a high heat flux test facility is designed for cyclic heat loading for testing ITER/DEMO plasma-facing components, for instance, the first wall panels. These tests represent the requirement for controlling the airborne particles of beryllium because the accurate knowledge of present beryllium in the workplace is crucial considering its high toxicity. During HELCZA operation a considerable attention is dedicated to safety procedures including measuring beryllium dust particles.
