Schott glass - metal sealed electrical feedthroughs

Schott glass - metal bolt sealed electrical feedthroughs, modern nuclear power plants to meet the highest safety standards 

Landshut, Germany and Shanghai, China, November 27, 2013 - International technology group SCHOTT has recently participated in nuclear safety organized by the China Nuclear Energy Association (CNEA) hosted. In this seminar, nuclear design institutes from China, the United States, France, Germany and South Korea, power companies, nuclear power plants and technology enterprises in more than 200 experts on nuclear safety expertise and technology in the field to exchange views and ideas. The summit's theme is how to significantly improve the level of safety of nuclear power plants. The prevailing view in the industry is to design conducting containment and containment equipment related components, you must use a higher safety standards, strict avoidance of major accidents, in order to achieve these goals. For example, flood or severe nuclear power plant accident (SA) could lead to a power outage, causing high pressure and high temperature condition occurs. The nuclear power plant accident of design components and parts made extremely complex requirements, especially for nuclear power plants and the safety concept of the core part - the reactor containment. It was before a serious accident must always remain controllable core elements and after. SCHOTT Technical Director Nuclear Safety, Dr. IEC (International Electrotechnical Commission) member Oliver Fritz said: "In order to achieve its containment structure for security purposes, the future must be consistent and higher margin of safety for all parts and components of the containment regulatory requirements. Currently, the global nuclear power industry is to define adequate margin of safety, and to amend the relevant regulatory requirements, to enhance the safety of nuclear power plants. Additionally, you need to simultaneously increase the IEEE (Institute of Electrical and Electronics Engineers), IEC (International Electrotechnical Commission) and other international Standard, in order to successfully achieve these objectives nuclear safety, "Deputy Secretary-General Xu Yuming China Nuclear Energy Association, said:" The biggest challenge we face is how to rebuild public confidence in nuclear power which is the most important task, however, only make nuclear energy to become a. items more secure and reliable technology, we can achieve this goal, "So far, Schott has more than 50 nuclear power plants around the world to provide a glass - metal metal security seal Electrical Penetration Assemblies (EPA). Sales Director SCHOTT Electronic Packaging Division and Chinese nuclear experts Derek Ye said: "Our electrical penetrations are China utilized, these electrical penetrations will be used for high-temperature reactors (HTR) primary circuit pressure vessel." Electrical penetrations are nuclear power plant safety equipment is important, but also the entire security an integral part of the shell. Schott electrical penetrations new brand Eternaloc unique proprietary-based Schott glass -? Metal sealing technology, than organic epoxy metal security seals technology has a greater advantage. 

     Recently, Schott Swedish Forsmark 3 nuclear power plant design a whole new generation of electrical penetrations. Currently, the nuclear power plant is being re-invested to improve its safety and reliability. The EPAs can achieve the latest operators to prevent serious accidents requirement that EPAs must withstand the requirements of various underwater environment can be maintained for at least 30 days in 13 meters of water, and withstand pressures up to 8.3 bar and 185 degrees Celsius. In addition, the electrical penetrations must withstand a dose rate 2360Gy / h of 1.7MGy radiation exposure value. Schott glass inorganic sealing material through the pressure boundary as the electrical parts that can minimize the effects of high radiation exposure, maintaining the integrity of the nuclear power plant after a serious accident containment. 

      Meanwhile, SCHOTT has developed to meet the small modular reactor design specifications of high electrical penetrations. These electrical penetrations can withstand high temperatures and pressures over 160 bar up to 320 degrees Celsius, can be used directly in the reactor pressure vessel. 

  Electrical penetrations nuclear reactor pressure vessel is the power circuit, control circuit and instrumentation circuits critical components. Its performance for running the reactor core functionality has a crucial role, and therefore must maintain adequate sealing strength to maintain the integrity of the reactor containment accident pressure in a variety of environments border. ? Schott Eternaloc Electrical Electrical Penetration Assemblies adopt more secure and high quality glass - metal sealing technology, which greatly exceeds the organic seal safety technology. Organic metal seal under extreme conditions of temperature and pressure can rupture, is Japan's Fukushima Daiichi nuclear power plant accident resulting. On the contrary, not aging inorganic sealing technology can be a good heat and radiation, thus ensuring the integrity of the metal seals housing and electrically through the reactor containment. Schott Eternaloc glass -? Metallic electrical penetrations are providing protection for nuclear reactors around the world, tested its service life up to 60 years. In 2012, Schott volunteered throughout its electrical parts in Alabama in Huntsville Wyle Labs conducted a rigorous test. Eventually, Schott electrical penetrations in accordance with IEEE317 successfully passed various quality standards and the identification of 344 tests, including the integrity of the test's 12 under conditions where the simulated earthquake.
