New risk-informed performance-based inspection program

A new risk-informed and performance-based inspection program will be enacted from April 2020. A part of this program builds on the information obtained from a probabilistic risk assessment (PRA). The significance determination process includes an incremental assessment of the risk incurred due to performance deficiency. The incremental risks of flooding and fire are determined from the results of an internal flooding PRA and internal fire PRA, respectively.

Internal flooding PRA:

The regulatory guide for reviewing the licensee's technical report for the extension of the operating period of commercial power reactors, enacted in November 2013, requires evaluation of the proof stress of the concrete structures of nuclear power plants operated for more than 40 years if the neutron fluence exceeds or may exceed a certain limit where neutron irradiation affects the concrete strength.

Although several previous studies showed effects on concrete strength, some obtained experimental data under material and temperature conditions different from those in the concrete

Uranium is an important nuclear material and contaminant with respect to the sites of uranium mining and whole nuclear facilities. As uranium can be released into the environment from these mining and facilities activities, it represents a typical actinide element, in various types of radioactive wastewater. Nuclear industries are thus point sources for potential release of uranium contaminated water into the environment.

   Some analytical methods, such as inductively coupled plasma-mass spectrometry (ICP-MS), spectrophotometry, alpha spectrometry, and laser fluorometry, are

About

„EUROSAFE“ is a global and European initiative aimed at promoting the convergence of technical nuclear safety practices in Europe. It is formed and managed by the EUROSAFE partners Bel V (Belgium), CSN (Spain), CV REZ (Czech Republic), MTA EK (Hungary), GRS (Germany), ANVS (The Netherlands), ENEA (Italy), INRNE BAS (Bulgaria), IRSN (France), NRA (Japan), Jacobs (United Kingdom), JSI (Slovenia), LEI (Lithuania), PSI (Switzerland), RATEN ICN (Romania), SSM (Sweden), SEC NRS (Russia), SSTC NRS (Ukraine), VTT (Finland), VUJE (Slovakia), a group of technical safety organisations (TSOs) and European regulatory bodies with nuclear safety expertise and competent in nuclear safety assessments, that create the EUROSAFE Association and the Programme Committee. Besides the authorities CSN, ANVS and SSM, all organisations are also members of ETSON, the European Technical Safety Organisations Network.

With a view to promoting the formation of a European scientific and technical network in the field of nuclear safety, the EUROSAFE Association has the following objectives:

  • to form a suitable forum for exchanges on analyses and R&D in the field of nuclear safety,to share experiences, and to exchange technical and scientific opinions,
  • to contribute to fostering the convergence of technical nuclear safety practices in Europe,
  • to further the definition and the implementation of nuclear safety research programmes.

The partners are aware that a high level of nuclear safety and radiation protection is a priority for the countries of Europe; they

  • recognise the reinforcement of the European dimension in the technical, economical and societal challenges which nuclear safety has to face,
  • take note that nuclear safety expertise plays a major role in contributing to the attainment and maintenance of a high level of nuclear safety and radiation protection,
  • acknowledge that the organisations competent in nuclear safety expertise develop appropriate approaches to safety issues as part of their assessments and research activities,
  • recognise the need for increased co-operation and reinforced sharing of experience between organisations competent in nuclear safety expertise.

The EUROSAFE Forums

Anchor Title: 
Forums

The EUROSAFE Forum is an international conference on nuclear safety and security, radioactive waste management and radiological protection. Since 1999, this event brings together representatives of organisations specialised in nuclear and radiological safety techniques, research institutes, power utilities, industry, public authorities and non-governmental organisations to inform about and discuss current developments and achievements in these topics.

Nuclear energy contributes approximately one third of European electricity production. A high level of nuclear safety is a priority for the countries of Europe. The technical safety organisations play an important role in contributing to that objective through appropriate approaches to major safety issues as part of their assessments and research activities.

The challenges to nuclear safety are increasingly international. Changes in underlying technologies such as instrumentation and control, the impact of electricity market deregulation, demands for improved safety, the ageing of nuclear facilities, waste management, maintaining and improving scientific and technical knowledge and the need for greater transparency - these are all issues where the value of an international approach is gaining increasing recognition.

The development of the European Union including its 2004 enlargement will also require closer collaboration between technical safety organisations and even more convergence in European nuclear safety practices. EUROSAFE aims to respond to these needs by offering a European forum for information on and discussion of important nuclear safety issues.

The EUROSAFE Tribune

Anchor Title: 
Tribune

From 2001 until 2016, GRS and IRSN published the magazine "EUROSAFE Tribune". Twice a year, this publication provided readers with articles about key issues in the world of nuclear safety and radiological protection, focusing alternately on the respective EUROSAFE Forum´s main subject and special topics.
