SCHOTT Receives ASME NQA-1 Certificate
Nuclear Safety Division Completes AREVA’s Supplier Audit for USA and Beyond
Electrical Penetration Assemblies (EPAs) serve as the feedthroughs for power, control, and instrumentation cables into the containment structures of nuclear power plants. With its compression glass-to-metal sealed EPA, SCHOTT offers a unique technology that ensures reliable hermeticity and pressure resistance. Due to the inorganic, non-aging glass seal, these EPAs offer an unlimited lifetime for the pressure barriers.
“We have been working together with SCHOTT for many years,” says Heiner Dornburg, Director Electrical Systems Projects at AREVA NP in Erlangen, Germany. “Now, that the NQA-1 supplier audit has been completed, we are looking forward to continuing this cooperation in the U.S. and other countries. Besides being very satisfied with their solutions, we can count on high-quality services by experienced application engineers and this is of great benefit.”
“Quality and superior technology have always been the keys to success,” says Thomas Fink, General Manager of the Nuclear Safety Division at SCHOTT Electronic Packaging in Landshut, Germany. “We manufacture according to KTA 3403 and IEEE317, our quality management system complies with ISO 9001, IAEA 50-C-Q and many others. This obviously contributed toward our extremely good performance in the NQA-1 supplier audit at first go,” he adds.
Since 1962, SCHOTT has delivered more than 12,000 EPAs that have been installed in about 100 nuclear power plants. They are still performing to specification without any maintenance whatsoever after more than 40 years in service. Nuclear power plants in Europe, South America, and Asia, as well as Japan’s nuclear powered ship “NS Mutsu” and Astute Class submarines by BAE Systems have also been equipped with EPAs from SCHOTT.
Compression glass-to-metal sealed feedthroughs consist of a metal housing, a glass sealant, and metal conductors. The preassembled component is heated up to a temperature at which the glass melts to the metal. During the cooling process, the metal housing contracts to a much greater extent than the glass does. This compression creates a highly pressure-resistant and hermetically sealed unit that ensures the highest safety level.
