Greater Safety, Lower Cost of Ownership
When you think of nuclear power, what comes to mind?For many, the image of a nuclear power plant hasn’t changed much from the first generation of large-scale reactors built in the mid-1900s. However, through the use of innovative components and forward-thinking design, modern nuclear power plants are becoming safer and more cost efficient.
SCHOTT is an international technology group with 130 years of experience in the areas of specialty glasses and advanced technologies. Using glass-to-metal sealing technology for the manufacture of hermetically-sealed components, SCHOTT has established itself as a trusted supplier of high quality and safety-relevant electrical penetration assemblies for the nuclear power industry dating back to the early 1960s.
Why is glass-to-metal sealing technology important?For decades, organic polymer seals have served as the status quo of the nuclear power industry. However, these seals cannot meet the demanding standards for high temperature and pressure resistance required by new builds of Small Modular Reactors (SMRs) or High-temperature Reactors (HTR), which represent the next generation of nuclear power innovation. Glass-to-metal sealing technology offers extremely robust high temperature and pressure resistance that makes it a safety-conscious, long-lasting feedthrough option for nuclear power applications, including and especially the latest reactor technology.
While polymer seals need to be replaced and decontaminated every 20-30 years because they degrade and age over time, non-aging glass seals are qualified for 60 years of use. Since they do not need to be replaced as frequently over the lifespan of the reactor, plant owners (and in most cases, tax payers) save in labor and material costs (based on an average figure of around 40 penetration replacements). Savings of $25-50 million can be realized when considering these figures in the reactor’s Total Cost of Ownership (TCO), in addition to the enhanced efficiency and safety offered by these components.
