Leak tightness testing system for nuclear fuel assemblies in wet conditions of interim spent fuel storage
The Slovak wet Interim Spent Fuel Storage Facility in the Jaslovske Bohunice nuclear power plant was built and put in operation in 1986. Since 1999, leak tests of VVER-440 fuel assemblies have been provided by the special leak tightness detection system 'Sipping in Pool' delivered by the Framatome-anp facility, with external heating for the precise detection of active specimens. Although this ...

How Residual Gas Analysis (RGA) Factors into Leak Detection
Leak detection is an essential aspect of vacuum operations, underlying critical performance indicators like cost, efficiency, and safety. Extraordinary effort has been made to engineer leak-tight systems capable of inducing and maintaining different vacuum regimes without significant loss of pressure due to leaks. Yet no system is perfect. Even the highest-quality chambers, gaskets, pumping ...

SF6 gas recovery for maintenance of high voltage equipment - Case study
Starting position / boundary conditions SF6 gas is a halogen compound, which as a greenhouse gas has a very harmful effect on the environment. It can remain stable in the atmosphere for 3200 years. The greenhouse effect for SF6 is 23'900 times as large as for the same quantity of CO2. In the 1997 Kyoto protocol, SF6 was listed as one of the six greenhouse gases which are prohibited from freely ...
