as_of = 03/20/2008Next 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 Essenbachand Niederaichbach.
Passive safety features
The safety feature begins with the so-called “passive safety feature” which includes the radio-active 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 features
The 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.
On-site storage facilities
By law, all nuclear power plants are forced to store their
atomic wastein on-site storage facilities near the power plant.
These temporary storage facilities have to be used until a final processing plant is built in a central location in Germany, to where all nuclear power plants would bring their atomic waste to. The usage of this storage is planned from
2030onwards, so interim storage facilities are necessary.
The nuclear power plants Isar must also therefore have its own temporary storage facility, which has been under construction since
15 June 2004.
Work on the temporary storage facility at the Isar location was marked by protest actions from environmentalist and resident groups, which voiced concern about possible health effects.
By plan, the interim storage facility of Isar I+II should be finished in the first half of the year
2006and can be used from then on.
Phasing-out of nuclear power
Concerns for the safety of nuclear power production were greatly increased after the Chernobyl accident in
1986, eventually leading to plans for its phase-out in certain countries. According to German Nuclear Phase-out regulations, Isar-I will be shut down in 2009, with operations in Isar-II continuing until 2020.
