On June 24th on the premises of Croatian Ministry of Economics regular exercise of TPC was held. This exercise was planned to be training for TPC members but also this opportunity was used to check once again organisational and working procedures of TPC. Before the exercise two new specialised softwares were installed in TPC. First, called Technical basis, is intended to be used for the fast development of technical basis and basis regarding public relations. The second software, called Hazard Assessment, was specially developed for the leader of TPC for fast and simple assessment of the consequences and countermeasures that may be implemented in the case of the nuclear accident in the NPP Krsko and NPP Paks. Company Enconet Int. developed both softwares.

Expert team of the Nuclear Safety Directorate of the Hungarian Atomic Energy Authority has finished the investigation of causes and consequences of the nuclear accident on unit number 2 in the NPP Paks. Results of the investigation have shown that several actions that were taken were not in co-ordinance with nuclear safety standards, technical regulation and quality assurance program. Complete report you may find here. According to the report, radiological impact on the environment was neglectable but economical consequences for the NPP Paks will be very high. For every day that unit number 2 will not be available NPP Paks will loose almost 200.000 euros, also costs for the removing of the accident's consequences and for a buying thirty new fuel elements that were destroyed in the accident cannot be neglected.

Major accident in Paks NPP. On Thursday, 10th of April a nuclear accident classified as major accident –third degree of the INES scale (see INES menu) happened in Paks NPP.
The operation of the reactor number 2 in Paks NPP had been stopped some ten days before the accident (Saturday, 29th of March), for the purpose of regular annual repairs. Nuclear fuel elements were transferred from the reactor into the fuel cooling pool. The process of cleaning fuel elements from surface layers was started for the purpose of more efficient fuel use in further operation. While the sixth set of 30 fuel elements (1/10 of reactor) was being cleaned on Thursday, 10th of April, the monitoring system installed in the reactor hall of the reactor number 2, late in the afternoon registered presence of inert radioactive gasses. The radioactive gasses had reached the reactor hall from the fuel elements cleaning system, which had not been properly hermetically sealed. Certain amount of inert gasses was emitted under control into the environment of the nuclear power plant through the ventilation system. Only one out of 9 automatic radiological measuring stations within a radius of 1,5 km from Paks NPP has registered a transitory increase in dose rate of 260 nSv/h (the average measured value of dose rate around Paks NPP is about 100 nSv/h; alarm value is 500 nSv/h). Radiological teams from Austria (Global 2000 environmental organization) executed independent measurings on Wednesday, 16th of April, which confirmed that radiological conditions around Paks NPP are at the level of background radiation. The HAEA (Hungarian regulatory body for atomic energy) has thus reached the conclusion together with the executive for safety in Paks NPP, that it is not necessary to undertake measures of protection for the surrounding population.
Based on information and data from Paks NPP and the disposable documents, the HAEA has decided to cancel the operating permit for the fuel elements cleaning system. It has also formed an expert commission with a task to investigate the whole case and control further works concerning the reactor number 2. At the same time inspection of fuel elements cleaning system by means of underwater cameras was started. It turned out that the damage on fuel elements is considerably bigger than expected. A big number of fuel elements (if not all 30) have been mechanically deformed. The lining of fuel rods has been damaged. The cause of damage was deficient cooling of fuel elements during the cleaning process.
