Electrabel, Group GDF SUEZ, submit conclusions for restart Doel 3 and Tihange 2
Over the last few months Electrabel has carried out an in-depth investigation
in response to the indications found in the reactor vessels of Doel 3 and
Tihange 2. On Wednesday, Electrabel submitted its conclusions and action plan
for restarting both units, to the Federal Agency for Nuclear Control (FANC).
Electrabel already submitted the technical dossier on Friday 30 November.
The voluminous technical dossier was executed by a multidisciplinary team,
assisted by national and international experts and academics. Based on an
examination of construction records, ultra-sound inspections, several tests of
the materials employed, and calculations on fracture mechanics, the report
reached the following conclusions:
- The construction of the power plants was in accordance with international
norms and standards;
- The initial hypothesis of hydrogen flaking that are stable and that were
formed during the forging process, was confirmed;
- Tests on more than 400 samples, performed by different laboratories, show that
the metal of the reactor vessels is sound, with properties that meet the
The technical report and the engineering and calculations demonstrate that the
vessels' structural integrity meets, within significant margins, all safety
criteria for each of the detected indications. The investigations and
calculations carried out were subjected to a stringent control procedure that
was validated by outside experts.
In conclusion, the results confirm the structural integrity of the reactors in
question, justifying the immediate restart and safe operation of Doel 3 and
Electrabel also submitted an action plan that sets out certain additional safety
measures it is taking to prepare for restarting the reactors, plus some
additional short and medium term measures.
It is now up to the FANC to provide its advice to the Belgian government.
Electrabel is available to the FANC and its experts to answer any questions they
may have on contents of the report.
