Stress tests

As it is known, on March 11th 2011, on the Eastern coast of Japan a series of events occurred:

  • An earthquake of 9 degrees magnitude on the Richter scale
  • Followed by a tsunami wave of over 14 meters which damaged 4 of the 6 nuclear reactors of the Fukushima 1 NPP
  • Total loss of energy supply which lead to loss of cooling sources and the increase of the nuclear fuel temperature and its deterioration. Hydrogen emissions and accumulations followed which later exploded and affected the containers designed to stop the spread of radioactive products.

In this context, the European Council decided on March 25th, 2011 that “the nuclear safety of all the nuclear power plants in the EU will be revised based on a transparent and extended risk analysis, the so-called Stress Tests”.

Following the above mentioned, SNN and the designers of Cernavoda NPP (AECL-Canada and ANSALDO-Italy), as per the requirements of the National Commission for the Control of Nuclear Activities assembled a team of the best nuclear experts, who drafted, after an extended analysis the report on the reevaluation of the safety margins at Cernavoda NPP, which was submitted to the National Commission for the Control of Nuclear Activities (CNCANC) on 28.10.2011.
