ANKARA, Nov 10 (Reuters) - A Turkish court has stalled the government's plans to build its first nuclear power plant by ruling as invalid several parts of a tender for the project, the TMMOB industrial body said on Tuesday.

Russia's Inter RAO (IRAO.MM) and Atomstroiexport and Turkey's Park Teknik won the tender last year to construct and operate the plant, but the consortium has been in protracted negotiations with the government over electricity pricing.

"The Council of State has decided to suspend three articles in the tender process," said Mehmet Soganci, chairman of the Union of Chambers of Turkish Engineers and Architects, or TMMOB.
