The first meeting of the international commission, initiated by the Russian Academy of Sciences with the membership of French, Swedish, Finnish, German, British, Norwegian and Russian experts, was held in Moscow, on 31 January 2018. The Commission concluded that there were no health effects for the population in the countries involved. The modelling calculations performed in different countries are consistent with each other, though there are too many uncertainties to make conclusions about the location of the Ru source. Since not only ruthenium 106, but also 103 isotopes have been measured in some countries, the hypothesis on the “medical” origin of Ru-106 (as a source for medical therapy) was excluded and the origin from fresh spent fuel was suggested.
WENRA’s Reactor Harmonization Working Group (RHWG) had a meeting in January 23-26 2018 at the Headquarters of the HAEA. The meeting was attended by more than 30 participants from 16 European countries and representatives of Canada, Japan were also present.
The VVER group of the OECD NEA's Multinational Design Evaluation Programme (MDEP) is a professional forum for the nuclear authorities of countries involved in the construction of new Russian VVER type nuclear power plant units. The 9th meeting of the Technical Expert Subgroup on Reactor Pressure Vessel and Primary Circuit took place at the end of January. Participants of the meeting discussed topics arising from the new units of Russian design from the national authorities' point of view.
Following the Fukushima accident in 2011, Hungary also performed the stress tests in relation to Paks Nuclear Power Plant to review its resistance against extreme hazards. The improvement actions decided upon the results were compiled into a National Action Plan that was published on the HAEA website. The HAEA reviewed the progress in the Action Plan in 2013, 2015 and in 2016 either for an EU request or for the international review conference of the Convention on Nuclear Safety. Approaching its completion, the HAEA, also complying with the EU expectations, reviewed the plan again in 2017.
The EU Nuclear Safety Directive (2014/87/EURATOM (NSD)) requires member states operating nuclear facilities to perform a Topical Peer Review at least every six years. The first Topical Peer Review took place in 2017. As the first step of the review, member states have to prepare a National Assessment Report in the specified topic, which they need to publish in English as well. Then member states mutually review each other’s reports, and the public may also make comments and put questions to them. Experts are also invited by the EU to study the reports. Finally, the results of the review will be discussed by the representatives of member states and the invited experts in an international peer review workshop in the spring of 2018. The results will be summarized in a report after the workshop.
