The Tihange Nuclear Power Station is one of the two large-scale nuclear power plants in Belgium, the other being Doel Nuclear Power Station. It is located on the right bank of the Meuse River in the Belgian district of Tihange, part of Huy municipality in the Walloon province of Liège. The primary stakeholder in the plant is the Belgian energy company Electrabel.


The plant has three pressurized water reactors, with a total capacity of 2985 MWe and makes up 52% of the total Belgian nuclear generating capacity.[1] Its units are rated as follows:

  • Tihange 1: 962 MWe (1975)
  • Tihange 2: 1008 MWe (1983)
  • Tihange 3: 1015 MWe (1985)

The reactors were supplied by different consortia, respectively ACLF (ACECOWEN-Creusot-Loire-Framatome), FRAMACECO (Framatome-ACEC-Cockerill), ACECOWEN (ACEC-Cockerill-Westinghouse).[2]

The units were designed for an operational lifetime of 30 years. In 2003, a Belgian law concerning the closure of the Belgian nuclear reactors permitted an operational lifetime of 40 years for the three reactors in Tihange. On July 4, 2012, however, the Belgian government decided that Tihange 1 could be operated until 2025.


On September 3, 2008 a malfunctioning fan was found in a reactor. This was classified as INES-1.[3] Also, in 2005 and 2002 there were two INES-2 incidents. And in 2001 and 1993 there were fires on the site of the nuclear power plant. Those were classified as level 0.[4]

Since 2006 there has been a leak of 0.5 up to 2 liters slightly radioactive water from a deactivation-bath.[5] After this was notified to the Belgium Federal Agency for Nuclear Control (FANC) (nl) Electrabel tried to find the cause of the leak. But on 11 July 2012 it became known, that the leakage still exists. According to FANC this issue is "under control" and no radioactivity leaks outside the buildings.[6]

September 1, 2012, it became known that the Tihange 2 reactor shows up to 0.3 m-depth signs of erosion weakening the outer reinforced concrete mantle. Electrabel and the Belgian nuclear regulator FANC deny any immediate security risk since the reactor was already shut down for maintenance.[7]

February 23, 2015, Dutch newspaper reports on thousands of cracks well up to 6 cm according to Federaal Agentschap voor Nucleaire Controle (FANC).[8] Actual discussion still assumes the reactor to be turned on in July again.
