September 2019 - RATEN ICN

Constantin PAUNOIU, Director RATEN ICN

Dear Reader,

Welcome to the September 2019 Edition of the EUROSAFE Newsletter, which has been prepared by the Institute for Nuclear Research (RATEN ICN). This gives us the opportunity to share some news about recent research activities and events in the field of nuclear technology and safety.

Our organization, subsidiary of Technologies for Nuclear Energies State Owned Company (RATEN), is providing scientific and technical support for the nuclear power activities in Romania.

The R&D activities are carried out in the frame of 18 research programmes, funded by the Romanian Ministry of Energy, 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, ESNII, MELODI) allow us to maintain a global vision and a high level of competence on safety assessments.

We are pleased to have the opportunity to share news about the most recent activities related to nuclear safety, together with some forthcoming events of possible interest for the readers.

I wish you a pleasant reading!

Director RATEN ICN,
Dr. Ing. Constantin PAUNOIU

Source term calculations for the relevant severe accidents in CANDU type reactors

Even if CANDU (CANada Deuterium Uranium) Pressurized Heavy Water Reactor (PHWR) plants have some commonalities in source term formation with the PWR, VVER type reactors, the particularities (horizontal fuel channels -two concentric Pressure and Calandria Tubes immersed in a large Calandria Vessel, heavy water filled; heavy water coolant and heavy water moderator;  short fuel bundles -roughly 50 cm long and 10 cm in diameter, placed horizontally in the core; natural uranium fuel; daily refuelling and shuffling), and especially the core configuration together with the complexity of the primary circuit, are highly impacting the modelling of severe accidents.
