In the organisation of Slovenian Nuclear Safety Administration (SNSA) workshop on the topic: "Accident
in the Nuclear Power Plant Paks - what we can learn from it?" was held on September 2nd in Ljubljana.
Nuclear experts from Slovenia and Croatia were attended on this meeting. They discussed
about the reasons that led to the accident in NPP Paks, accident course and consequences. Responsible persons
from NPP Krsko convinced experts and responsible persons from SNSA that similar accident is not possible
in their power plant because of diversities in the technologies and procedures. More about workshop you
can find here.

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
May 5, 2003
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.

on the main manu and then click the ordinal number of the measure station
A new specialised software called PC-995 has been installed and it is meant for
estimate of the state of a Nuclear Power Plant under the conditions of possible
accident. The software has been made by the company Enconet International and it is conforming
with recommendations of the International Nuclear Energy Agency (IAEA).

protection and rescue. This bill establishes The Public Protection
and Rescue Administration that becomes competent in matters of
activity-coordination of all the participants in protection and rescue,
as well as monitoring of the implementation of protection measures.
The bill was given its first reading in the Parliament. Its application
is expected to start in June 2002.
From the 3rd to the 6th of February an international conference going by
the name of PIME 2002 - accelerating nuclear communication was held in
Prague, organised by the European Nuclear Society. One of the main issues
of the conference was notifying of the public in case of a nuclear emergency.
Two young experts of the firm Enconet Int. took part in the work of the conference,
both active in the project for improvement of our nuclear emergency response
At the request of the Ministry of Economics, Enconet Int. has made The Proposal
of implementation strategy of the measure of protection by means of stable
iodine prophylaxis. The main purpose of the Proposal is to initiate an expert
debate on this subject. The Proposal is based on the estimated number of
5.125.000 unit-doses, that is 1.025.000 packages of stable iodine tablets.
A close estimate indicates that a total cost of implementation of the proposed
strategy of stable iodine prophylaxis of the thyroid gland could amount up to 1
million US dollars. The production of the implementary plan should come within
the shared competence of the Ministry of Health and the Ministry of Home Affairs.
