WENRA Guidance on Article 8a of the Nuclear Safety Directive - Draft for Public Consultation

March 29, 2017, 8:15 a.m.

The ENSREG meeting (24th November 2015) discussed the implementation of Art 8a of the Nuclear Safety Directive and invited WENRA to provide guidance on the question of “timely implementation of reasonably practicable safety improvements to existing nuclear power plants”. A WENRA Ad-Hoc Group was established in April 2016 to bring forward a guidance paper on the “timely implementation of reasonably practicable safety improvements to existing nuclear power plants” (Article 8 a). The UK agreed to Chair the group with members from Finland, Germany, France, Hungary and Switzerland. It was agreed the guidance should be finalised prior to the implementation date for the Nuclear Safety Directive in August 2017.

WGWD Processing Report Open for Stakeholder Comments

Nov. 14, 2016, 10 a.m.

During the fall meeting in Rome, WENRA approved the most recent safety reference level report produced by the WGWD. The report covers safety relevant issues of waste processing from small mobile equipment up to large stationary installations and facilities. As this document is adressing the process of generating the final waste package to be disposed of in a repository, there are strong links to the disposal as well as to the storage report.

HERCA-WENRA Workshop Concludes

June 15, 2016, 9:39 a.m.

Trust between authorities competent in radiation protection, nuclear safety and civil protection authorities is of fundamental importance to establish the rapid and reliable channels of information, communication and alerts necessary for a harmonised approach in the early phase of a nuclear accident. This was one of the conclusions from the HERCA WENRA Workshop on the implementation of the HERCA WENRA Approach, held in Bled, Slovenia on 13-15 June 2016.

Workshop on the Implementation of the HERCA-WENRA Approach

May 9, 2016, 6:21 a.m.

HERCA and WENRA jointly organise a workshop on the implementation of the approach for cross-border emergency preparedness on 14 and 15 June 2016 in Bled, Slovenia. Committed to engage cooperation at national level with the competent authorities in charge of civil protection, the two associations has invited national civil protection authorities from Europe to participate in the workshop. The objectives of the workshop are to share experience on the implementation of the HERCA-WENRA Approach, to discuss issues identified and to define steps for addressing them.

A little more than one year after WENRA presented the final version of its waste and spent fuel storage report (Ver. 2.2 ) the final version 2.2 of the decommissioning report is now publicly available. In part III of this report all WENRA countries have documented their efforts to update their national regulations regarding the previously released set of reference levels as of the 2012 report version 2.1. Country specific fact sheets and status tables have been added in this final version of the report as well as a comprehensive description of the whole procedure.

WENRA-HERCA side event on Emergency Preparedness

Sept. 21, 2015, 1:48 p.m.

To introduce the HERCA WENRA approach for a better cross-border coordination of protective actions during the early phase of a nuclear accident, WENRA and HERCA held a side event during the 59th IAEA General Conference in Vienna. At the side event, Chair of the HERCA Working Group on Emergencies Georges Piller presented the approach, which introduces a common European emergency preparedness and response approach on coordination, independent of the scenario of the accident.

Flaw Indications in Swiss Nuclear Power Plant Beznau

July 16, 2015, 9:18 a.m.

While carrying out ultrasonic measurements of the reactor pressure vessel of the Beznau 1 nuclear power plant in Switzerland, the operator detected flaw indications that require evaluation. The operator Axpo submitted a corresponding report to the Swiss Federal Nuclear Safety Inspectorate ENSI yesterday. Beznau 1 is presently inactive because of the main annual overhaul. ENSI is now awaiting an assessment of these findings by Axpo. Operation of Beznau 1 may only be started again if the safety of the reactor pressure vessel is confirmed.

Doel 3/Tihange 2: next steps of the review process

May 13, 2015, 8:09 a.m.

At the end of April 2015, FANC held another meeting in Brussels with the International Review Board, an international panel of experts in the effects of radiation on material properties. The experts investigated the results of the additional test campaigns conducted by Electrabel over the past year. These mechanical tests were carried out on specimens containing hydrogen flakes that had been previously irradiated in the BR2 research reactor at the SCK•CEN.

FANC publishes Guidelines for new nuclear Class I installations

May 6, 2015, 4:24 p.m.

The Belgian nuclear regulatory authority FANC has developed guides for new nuclear class I installations on the safety demonstration and on specific external hazards. The guide on the safety demonstration provides expectations by the nuclear regulator with respect to defence in depth, quantified safety objectives and external hazards in general. The specific guides on external hazards provide expectations on how one or more hazard levels can be derived with the purpose to include these in the safety demonstration; these guides address respectively seismic hazards, unintentional aircraft crashes and external flooding. During the development of the guides use was made of several sources including WENRA documentation and the recently issued European Council Directive 2014/87/Euratom of 8 July 2014 which amends Council Directive 2009/71/Euratom. The contents of the guides have also been discussed extensively with licensees and advisory bodies.

Natural Hazards Guidance Document

April 27, 2015, 4:18 p.m.

The WENRA Reactor Harmonization Working Group (RHWG) recently completed the Guidance Document for Issue T: Natural Hazards. One of the Key recommendations from ENSREG following the completion of the European Stress Tests was to develop reference levels and guidance on the subject of Natural Hazards to drive harmonisation and improve safety. The purpose of this Guidance is to provide explanations of the intent of the Safety Reference Levels (RLs) of Issue T, to contribute to a consistent interpretation and to permit insights into the considerations which have led to their formulation. In addition, some background information is provided for easy reference. This Guidance does not define any additional requirements. Furthermore, it is important to recognize differences in national regulations and in reactor designs when using this document. However, the overall content and meaning is in all cases relevant.

The members of WENRA have agreed to accept Serhii Bozhko, Chair of the State Nuclear Regulatory Inspectorate of Ukraine SNRIU, as a new WENRA member with immediate effect. The Terms of Reference were signed during the WENRA spring plenary session held in Geneva. "Since they joined WENRA as an observer in 2009, Ukraine has contributed to the work of the WENRA and its working groups RHWG and WGWD in a constructive and cooperative manner. Ukraine have proved able and willing to comply with WENRA safety reference levels and technical criteria for the safe operation of its nuclear power plants," says WENRA chair Hans Wanner. "It is therefore with great pleasure that we today can announce the inclusion of Ukraine as a new WENRA member."
