Custom Reactor Pressure Vessel (RPV) Seals
CUSTOM RPV SEALS HELP EXTEND GERMAN NUCLEAR POWER PLANT’S OPERATIONS
Many are concerned about the recent German energy crisis’s effects on the economy, private households, and the wider European power grid. As such, the German government is facing increasing pressure to address the crisis.
One of the main challenges is a shortage of electric energy in the power distribution grid. This shortage has been caused by several factors, including the closure of several nuclear power plants (NPPs) in the country, which has reduced the energy supply. In response, the German government agreed to extend the operation of the remaining NPPs in their regular service until at least April 2023.
Extending the Isar 2’s Energy Production
As one of the remaining NPPs, Preussen Elektra’s Isar 2 is a 1450 MWe pressurized water nuclear power reactor facing a shortage of Reactor Pressure Vessel (RPV) seals, one of the most crucial parts of an NPP as they keep the pressurized water from leaking into the environment. Thanks to our longstanding relationship and expertise in the nuclear industry, we were able to develop a custom solution for PreussenElektra.
Requiring RPV seals, O-rings, and 195″/190″ diameter seals made of Inconel 718 and silver electroplated, we supplied one set of RPV O-rings that arrived at the NPP site before Christmas 2022. The manufacturing process, including source inspection and airfreight from Atlanta, GA, to Frankfurt, Germany, and onward to Bavaria, was managed with great care to ensure timely delivery.
Technetics’ RPV Seals Help Provide Energy to Germany
Our process for creating the Isar 2 RPV seals was flawlessly executed to accommodate PreussenElektra’s requirements.
First, the source inspection at TG Columbia was completed satisfactorily, and the shipping approval was obtained as planned. Then, we worked with Isar 2 to ensure the solution arrived during their scheduled outage. These outages occur every 12-18 months and are a standard procedure for pressurized water nuclear power reactors to reorganize nuclear fuel bundles inside the reactor and ensure that all fuel is burned off equally, optimizing efficiency and reducing costs.
The RPV seals arrived on time and were installed with no issues or unplanned downtime, allowing the entire process to be carried out with precision and efficiency. As a result, the installation of the RPV seals was completed successfully, enabling the Isar 2 nuclear power plant to resume normal operations without any further disruptions to the German energy supply.
The successful installation of the RPV seals helped to prevent further disruptions to the German energy supply and ensure the safety of the Isar 2 nuclear power plant.
