Isar Nuclear Power Plant

Next to the Isar river, two base load nuclear power plants have been built, called Isar I and Isar II. They are fourteen kilometres away from Landshut, between Essenbach and Niederaichbach.SafetyPassive safety featuresConsequentially shielding: The safety feature begins with the so-called “passive safety feature” which includes the radioactive materials in the reactor core (also by accidents) to protect them from the outside environment.Safety in- and outward: Fuel pellets, Fuel-Rod casings, reactor pressure vessel, biological shield, steel containment structure and the outer ferro concrete mantle are six of the most important passive safety features.Active safety featuresThe passive safety installations are supplemented by a lot of automatically working “active safety systems” whose reliableness is based on their plural existence and their autonomously working in separate rooms.This is as necessary for the internal electric power supply as for the reactor cooling system, which guarantees the reliable thermal dissipation in every operating status, even when an implausible accident ingresses (for example a break of a primary coolant line).It constantly controls and compares all the important key operating parameters of the plant and activates automatically the necessary protection measures (independent from the plant operating personnel) if a parameter reaches a limit value.For example, the protection system may initiate a rapid shutdown and aftercooling procedure.The futureOn-site storage facilitiesBy law, all German nuclear power plants are forced to store their atomic waste in on-site storage facilities near the power plant.
