4. TRANSFER OF KNOWLEDGE ON NUCLEAR SAFETY AND TRAINING ORGANIZATION


  European Nuclear Safety Training and Tutoring Institute

ENSTTI was established in 2010. The Institute is closely related to the European Technical Safety Organization Network ETSON and technical safety organizations participating in this EU community. The objective of ENSTTI is to provide training, consulting and practical services in the assessment of nuclear and radiation safety. It is intended for technical support organizations to share their experience on enhancing nuclear safety, dissemination of news and practical experience in the field of nuclear safety culture.
Specialists of the Laboratory of Nuclear Installation Safety completed the implementation of a two-phase training project Training and tutoring for experts of the Nuclear Regulatory Authorities and their technical support organizations ordered by the European Commission. In accordance with the project the laboratory specialists participated in three training courses, two of which took place in LEI:

1. Nuclear Reactor Safety I, Bologna, Italy, May 2-6.,
2. Criticality Safety, Kaunas, Lithuania, May 9-13.,
3. Regulatory framework for decommissioning of Nuclear Facilities, Kaunas, Lithuania, May 16-20.
 
Trainings on criticality safety were also held by specialists from Ukraine (SSTC NRS) and Italy (ENEA), whereas trainings on nuclear objects decommissioning – by SSTC NRS (Ukraine) and IRSN (France) specialists. Participants were from different countries: Egypt, South Korea, Malaysia, Nigeria, Ukraine and Vietnam.

Since 2016 ENSTTI launched a new training project organized following the order of the European Commission Training and Tutoring for experts of the National Regulatory Authorities and their Technical Support Organisations for developing or strengthening their regulatory and technical capabilities. In accordance with this project a tutoring was organized for three nuclear energy specialists from Algeria. Tutoring Safety assessment of nuclear reactors was comprised of two parts: introductory part common for all specialists and specific trainings prepared for each specialist individually with certain individual tasks. During introductory first month trainings the specialists from Algeria were introduced with basics of nuclear energy safety and deterministic safety analysis. The laboratory specialists delivered lectures and consulted on the issues of reactor neutron kinetics, processes in nuclear fuel rods, reactor cooling circuits and their surrounding containments and probabilistic safety assessment. In the second tutoring part the foreigners performed individual tasks, they were consulted by LEI experts of certain field. The tutees developed numerical models of nuclear fuel rods or experimental facility, conducted structural and thermal-hydraulic analysis for nuclear fuel rods. The tutees from Algeria were also consulted on best estimate application issues, they used all available (at the institute) technical and software equipment. Active participation of LEI specialists in training courses and tutoring as well as their organization is beneficial for the organizers as well – in such way the institute is being promoted, new contacts are created, information is updated and systemized, qualification of consultants-experts is constantly improved.

  Transfer of the European Regulatory Methodology and Practice to the Nuclear Safety Authority of Belarus

In 2016, works of BY3.01/09 (BE/RA/07-A) project Development of technical cooperation in nuclear safety in the field of assistance to regulatory authorities, initiated and financed by the European Commission, were continued. The objective of this project is to support Regulatory Body of Republic of Belarus Gosatomnadzor in nuclear safety regulation activities, in licensing construction for Belarus NPP, also training Belarusian experts to properly perform the review of documents related to nuclear activity. In 2016, the first part of the project, related with support in supervising licencing documents, was completed, meanwhile the second part of the project, devoted to trainings of Belarus experts on how to use Western software codes, was launched. Experience gained by these experts will enable them to conduct independent safety analysis for constructed Belarus NPP. In BE/RA/07 project, which is managed by RISKAUDIT, besides LEI, the role of European experts was played by GRS and HZDR (Germany) and SSTC NRS (Ukraine). LEI specialists will participate in the trainings for preparing Belarusian experts on how to use ATHLET, COCOSYS and ASTEC codes. Trainings will be launched in 2017.

Such support to the neighbour country is necessary in order to ensure timely and effective supervision of the constructed nuclear power plant by Belarus nuclear regulation institutions. This is very important not only for Belarus, but also for Lithuania (at the border of which this nuclear power plant is constructed) and for the entire Europe.



5. PARTICIPATION IN EU RESEARCH ORGANIZATIONS AND COMPETENCE NETWORKS


  European Technical Safety Organizations Network

Since 2009, the researchers of the Laboratory of Nuclear Installation Safety have participated in the activity of European Technical Safety Organizations Network (ETSON). Presently, ETSON consists of ten member organizations: BelV (Belgium), INRNE BAS (Bulgaria), CV Rez (Czech Republic), AMEC (Great Britain), LEI (Lithuania), IRSN (France), VTT (Finland), PSI (Switzerland), JSI (Slovenia), VUJE (Slovakia), MTA (Hungary), GRS (Germany), and three associated member organizations: JNES (Japan), SEC NRS (Russia) and SSTC (Ukraine). In 2015, new ETSON president was elected, BelV director general Benoît De Boeck.

The main objectives of ETSON are as follows:
• stand for an exchange forum on scientific research and development of nuclear energy safety;
• contribute to fostering the convergence of nuclear safety practice in Europe and beyond;
• plan nuclear safety scientific research programs and promote their implementation;
• speed up the application of the EU Directive on nuclear safety;
• cooperate in implementation of safety assessment and research projects.

Fourteen expert groups were established in ETSON network in key nuclear safety research areas.
LEI representatives actively participate and have their representatives in all the main structures and groups of ETSON organization. In 2016, LEI specialists participated in ETSON organization network forum EUROSAFE, which was held in Munich on November 7-8. Issues of nuclear safety, scientific research, nuclear waste management, radiation safety and emergency preparedness as well as nuclear equipment and materials’ security were analysed. The chairman in the section of nuclear waste management, operation decommissioning and dismantling was appointed LEI director. LEI activity was represented in poster as well. Participation of ETSON members in planned and implemented EU projects is constantly being discussed  in ETSON expert and  coordinating group meetings, for example in programme Horizon 2020.  At these meetings one can learn about the latest ideas of performance and application of deterministic safety, risk assessment and probabilistic analysis and contribute to the implementation of new research and applied works in the field of nuclear safety analysis. Participation of young researchers enables to get better involved into a network of young specialists from different countries, encourage scientific and intercultural cooperation. Therefore, participation in ETSON network helps to get involved in new international projects and promote LEI.
