Beryllium dust generation caused by HHF tests

Popis výsledku v původním jazyce

Beryllium will be used as a plasma-facing material of the ITER reactor components. One such component is the ITER first-wall panel, which contains a layer of beryllium tiles on the plasma-facing surface. Full-Scale Prototypes (FSP) of these panels are undergoing qualification through a series of cyclic High-Heat-Flux (HHF) tests at the HELCZA (High Energy Load Czech Assembly) facility. Such process, directly and indirectly, causes disintegration of the beryllium surface and results in beryllium dust formation. With regards to the beryllium toxicity, it is crucial to monitor the occurrence and the spread of the mentioned dust to ensure personnel safety. Moreover, it is necessary to decontaminate FSPs from the beryllium dust at the end of HHF tests. This study deals with the monitoring of the beryllium dust concentration levels on the FSP after HHF testing at HELCZA and its spread to the vicinity of the testing area, with the aim to provide a basis for safe operation.
