Karlsruhe. At the weekend, Block 2 of Philippsburg atomic power station (KKP 2) was taken out of operation according to plan for the annual inspection. In the coming weeks, inspection and maintenance work will be carried out, and 44 of the 193 fuel elements will be exchanged.
“This year, the main focus of the inspection is on routine work,” reports Horst Janisch, Manager of the Block 2 system. “The major individual projects include the inspection of one of the four main coolant pumps, the pressure testing of two of the four steam generators, and the inspection of one of the three low-pressure turbines.” In all, the work schedule comprises over 4,000 different activities. In these, the inspection team at KKP have the support of more than 1,200 additional employees of manufacturing and specialist companies.
“The inspection exemplifies our maxim, ‘Safety before profitability’. This year, we are again spending tens of millions, thus keeping the plant up to the current standard of technological development. This is an essential contribution to safe operation and to continued CO2-neutral electricity generation,” Horst Janisch explains.
The inspection work is carried out under the supervision of the Baden-Württemberg Ministry of the environment, and is being assisted, by order of the Ministry, by experts from the TÜV, the KeTAG (atomic technology experts’ association, Baden-Württemberg) and the MPA (stare material testing institute, Stuttgart).
Block 2 of Philippsburg atomic power station is a pressurised water reactor with an electrical output of 1,458 megawatts. The plant was put into operation in 1984, and generated over eleven-and-a-half billion kilowatt hours of electricity in 2006.
