November 2018 - ENEA


Dear Reader,

Welcome to the November 2018 Edition of the EUROSAFE Newsletter, which has been prepared by the Nuclear Safety, Sustainability and Security Division (SICNUC) of the ENEA Department on Fusion and Technology for Nuclear Safety and Security (FSN). This give us the opportunity to share some news about recent research activities and events in the field of nuclear technology and safety.

ENEA is the Italian National Agency for New Technologies, Energy and Sustainable Economic Development under the aegis of the Italian Ministry of Economic Development. It is a public, non-profit body operating in the fields of Energy Efficiency, Renewable Energy Sources, Nuclear Energy, Climate and the Environment, Health and Safety, New Technologies and Electric System Research. The mission of ENEA is to develop research and technology innovation, to provide advanced services for the energy sector, notably the nuclear sector, and to foster sustainable economic growth.

ENEA supports national institutions on a variety of nuclear activities, including: legacy from former nuclear program and related fuel cycle (e.g. waste and repository), evaluation of current and innovative reactors as well as fusion systems, radiological/nuclear activities for non-power applications (e.g. medicine or industry), nuclear security and non-proliferation. The support provided by ENEA includes expert advice, assessments, measurements, monitoring etc.

Specifically the SICNUC Division has also been developing methods and capabilities for nuclear emergency preparedness and response intended to support the Italian authorities, also providing expertise for scenario-based exercises.

The R&D activities, here presented, are carried out within the frame of research programs funded by the Italian Ministry of Economic Development for developing and maintaining expertise in nuclear safety and security, as well as in the framework of EURATOM Programs. In parallel, the extensive participations in Collaborative Research Projects, Technical Working Groups and Committees of International Organizations (IAEA; OECD-NEA) and Initiatives (ETSON, NUGENIA, IGD-TP, ESNII, MELODI) allow to maintain a global vision and a high level of competence on safety assessment.

I wish you a pleasant reading!

Developments in Monte Carlo Radiation Transport

The increase in computing power of the last few decades has changed the role of the Monte Carlo (MC) method in radiation transport from that of reference benchmark to design tool. The range of problems coming within the remit of MC has become ever greater. All the same, the intrinsic weakness of MC, that all results come with a statistical uncertainty and furthermore to halve the uncertainty requires, under the best of circumstances, four times the calculation time, remains.


DTT: a step towards the Fusion Reactor

In the 2012 the European Commission issued an important document tracing the “Road Map” to achieve the goal to realize a demonstrative Fusion Reactor (DEMO) in the second half of this century. Along this “walk” it was recognized as a possible show stopper the so called “power exhaust”. In a Tokamak configuration part of the energy enclosed is not confined by the magnetic topology. In order to control these losses a dedicated magnetic configuration (the so called X point) drives the lost energy flux in a dedicated region (the divertor).


International Best Practices and Lessons Learned on the Public Engagement of the Back End of Fuel-Cycle

On October 12 2018, the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA), hosted in its premises at Frascati (Rome) a one day workshop to debate best practices and lessons learned from national and international experiences on the public engagement in the back-end of the nuclear fuel cycle.

ENEA-Bologna Nuclear Data Group Activities for Nuclear Safety

The Nuclear Data Group (NDG), included in the ENEA Nuclear Safety and Sustainability Division in Bologna, has recently obtained significant recognition by the OECD-NEA Data Bank for the excellent quality and the importance of the work done in the last 20 years in support of international cooperation. Since 2001 NDG has been engaged in the production and validation of a dozen of multi-group and continuous-energy neutron and photon nuclear cross section libraries, dedicated respectively to deterministic and stochastic (e.g. Monte Carlo) transport codes.

Stable and radioactive isotopes environmental monitoring

Before designing the construction of a repository, preliminary data must be collected to characterize the site, including identifying the Zero State. It defines the conditions of all the environmental parameters needed to verify whether the construction and operation of the deposit have had a significant impact on the environment and on the population in the future.


ALFRED on the licensing path

The ALFRED project, aimed at realizing a demonstration lead-cooled fast reactor in Romania, was launched in 2013 with the signature of the “fostering ALFRED construction” (FALCON) international consortium among the Italian Ansaldo Nucleare and ENEA, and the Romanian RATEN-ICN. The project kick-started after the conclusion of the EURATOM FP7 “LEADER” project, within which a collaborative endeavor of 18 European organizations set the conceptual design of the ALFRED reactor.

FASTNET School - 21-25 January 2018 Bologna, Italy

In the framework of the H2020 project FASTNET (Fast Nuclear Emergency Tools,, a School on Emergency Preparedness and Response will be organized by ENEA in Bologna, Italy, during the week 21-25 January 2019. The detailed program (including general lectures or presentations focusing on the project results, round tables and emergency means demonstration) is being finalized. The School is offered at no cost. The number of allowed participants is however limited, and a selection will be made by the FASTNET Management Team shall a too large amount of requests be received. For further information, please contact Federico Rocchi at the email address below.
