In the framework of the IAEA CRP (I31033) an uncertainty quantification exercise is currently under development based on test-6 of the QUENCH experimental facility and ENEA is participating. The current status of the ENEA activity is here summarized.

Monitoring chlorine cycle in environmental matrices is important to better characterize the reference state and the water cycle for the predisposal planning of radioactive waste. Methods and protocols for 36Cl  analysis in environment have to be tested in order to monitor  the performance of the radioactive waste repository.

Currently an uncertainty application exercise against the Phebus FPT1 test is in progress in the MUSA HORIZON 2020 EURATOM project. ENEA is the lead of this uncertainty exercise that it has as a main target to training the project Partners gaining experience for the nuclear power plant and spent fuel pool uncertainty application planned along the project.

The  Fukushima Daiichi nuclear accident having its 10^th anniversary, here is a compilation of content published by the members of ETSON on this occasion.

There is a need for the construction of supplementary interim storage capacity for spent fuel in Belgium, because of the definitive shutdown of the 7 nuclear power plants in the next 4 years.

In the framework of the OECD/NEA PKL projects [1], Bel V proposed to perform a series of experimental tests connected with the Natural Circulation Interruption (NCI) issue. The objective was to assess the natural circulation interruption phenomena under asymmetric cooldown conditions and its eventual impact on the current operating emergency procedures (EOPs).

According to the European Research Roadmap to the Realisation of Fusion Energy the next step after ITER facility is DEMO, the demonstration power plant.

The Ignalina Nuclear Power Plant (INPP) was operated with two RBMK-1500 reactors for 21 and 22 years respectively. Since 2010, decommissioning has become the major activity at Ignalina NPP.

Lithuanian Energy Institute (LEI) is participating actively in IAEA activities by performing six Coordinated Research Projects (CRPs) in different nuclear fields, three of these were initiated in 2020.

Rostechnadzor is to update regulatory requirements to computer programs used for safety analysis of nuclear installations in 2021.

To promote the exchange on the challenges posed to nuclear safety by the current Covid-19 pandemic, ETSON conducted a workshop in 2020. Now ETSON has published a workshop report which summarises the contributions of the partaking organisations.

PRO ALFRED project - Activities for the Preparation of the ALFRED Research Infrastructure Development in Romania  was devoted to strengthen  the  Romanian capability for an increased national  participation in the ALFRED Infrastructure implementation.

The European Joint Programme on Radioactive Waste Management (EURAD) will help the EU member states to obtain the know-how required to implement safe and long-term management of radioactive waste.

The work on Kraken started recently and has proceeded to the first validation calculations for operating cycle simulations. Transient simulations will soon follow.
