At the existing P8 testbed, testing of components, like combustion chamber, nozzle, etc. is conducted. The planned expansion will add the new P8.3 building and extend the supply systems.
The testbed consists of a test cell with an opening roof, as well as diagnostic rooms, an MCC room and storage facilities for various fuels. A catch basin with a retention capacity of 250 m3 is planned for collecting process water, quench water and rainwater.
