LEI Contribution to Transfer of Knowledge on Nuclear Safety

The European Nuclear Safety Training and Tutoring Institute (ENSTTI) was created by Technical Safety Organization Network (ETSON) with the ultimate goal to provide initial training and continuous qualification programs to ensure that personnel at European Nuclear Regulatory Authorities and Technical Safety Organizations can maintain skills in their current positions and remain prepared to take on emerging tasks or advancements.

Lithuanian Energy Institute participated in training activities from the establishment of the Institute in 2010. Specialists of LEI in 2016 participated in the 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 LEI experts participated as trainers in three training courses, two of which took place in LEI:

1. Nuclear Reactor Safety I, Bologna, Italy, May 2-6, 2016,

2. Criticality Safety, Kaunas, Lithuania, May 9-13, 2016,

3. Regulatory framework for decommissioning of Nuclear Facilities, Kaunas, Lithuania, May 16-20, 2016. 

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 has been providing training and tutoring for Algerian nuclear energy experts in the framework of the International Atomic Energy Agency's Technical Cooperation Program "Training of National Trainers and Experts in Engineering Nuclear Safety and Security (Oracle Project No. 1060227)". As part of this project, a two-month tutoring session for three Algerian nuclear energy specialists was organized at LEI in the autumn of 2016. This tutorial on Nuclear Reactor Safety Assessment 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 LEI 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, and qualification of consultants-experts is constantly improved.

Starting from 12 March till 2 June 2017, training “Safety Assessment of nuclear installations. Probabilistic Safety Analysis” was organized for Algerian nuclear energy specialists Rabah BENABID (Nuclear Research Center of Birine) and Abdelkader BOUHLAL (Nuclear Research Centre of Draria) at the Lithuanian Energy Institute. The training took place as  part of International Atomic Energy Agency’s (IAEA) project “Developing  a Knowledge base and Strengthening Competence in the Field of Nuclear Safety Assessment” (ORACLE project No. 3060501). LEI experts, being part of European Nuclear Safety Training and Tutoring Institute, were asked to transfer knowledge and improve qualification of Algerian specialists. The tutees were introduced to basic principles of Nuclear Safety and to Probabilistic Safety Analysis. The training was organized according to ESNTTI methodologies through lectures and consultations, the tutees also received individual assignments. At the end of the traineeship the tutees prepared reports to IAEA and ENSTTI.

One more training session is planned for the Algerian specialists Djemai MERROUCHE and Hocine BENKHARFIA (both from the Nuclear Research Center at of Birine) for the Autumn of 2017 (12 Sept – 1 Dec). The 12 week training will cover Safety Assessment of Nuclear Devices, Probabilistic and Deterministic Safety Analysis, Modelling of Neutron Kinetics in Nuclear Reactors.
