Nuclear energy in HungaryNuclear energy in Hungary

Hungary operates a 4x500 MWe VVER NPP at Paks. Lifetime of the units will be extended until 2032-2037. The plant provides about 35-40% of electric energy of the country.

It is decided to build two 1000-1600 MWe units at the same site by 2020-2025.

The country has a National Energy Strategy since 2011, involving nuclear.

Two research reactors are in operation (10 MWth and 0.5 MWth). The nuclear regulation is largely harmonised with the international

requirements. It covers also research reactors.LILW (Long lived low and intermediate level waste) repository is

constructed. NPP spent fuel is stored in a dry storage facility. Final solution concerning spent fuel and HLW (high level waste) is not decided.

National National nuclear research history and statusnuclear research history and status

• The history started in ’50s• 1959 KFKI Research reactor• 1971 BME Training reactor• PAKS, Generation II. units 1982-1987, 4 units has commissioned

• Safety of Paks is acceptable by European standards too, because:• Conservative design of VVER-440/V213 units• Quality requirements during the construction of the units• The man-machine interfaces were replaced in due time by modern tools• The operation of modern safety authority• The timely review of the safety of the units by adequate tools widely

accepted• The safety improvement program executed on all the units.

Summary: a large national program launched in the early ‘90s on safety, also forming the basis of knowledge transfer, and further improvements (power uprate, licence extension)

• Nuclear R&D has a long tradition in Hungary• In the ’90s, the national research and design institutes were more

and more supported the operation of Paks NPP• From 2007, the preparation of the new units started: Teller

project. The necessary studies were prepared.– Feasibility report of the new units.– Preliminary environmental impact analysis– Handling of nuclear waste.

• In 2009, the government decided to strengthen the national R&D. First stage was the creation of the Vision report.

The national nuclear R&D programmeThe national nuclear R&D programme

• Paks units 1-4– maintaining compentence for the extended lifetime.

• Paks units 5-6– safety depends on the knowledge of the new technology.

• Modernizing the fuel cycle (reduced radioactive waste, supply of nuclear fuel in the long term) – national, regional and worldwide problem, the main tool will be the use of new generation fast reactors

A nationwide nuclear R&D programme is developed in 2010/2011. Creation of the Sustainable Atomic Energy Technology Platform in 2010

Main fields of interest:• nuclear materials• modelling and simulation• closing the fuel cycle and GenIV reactors• research infrastructureThe strategic research agenda (SRA) has been created with the four main

chapters above.

ALLEGRO: Gen IV. gas cooled fast reactor demonstratorALLEGRO: Gen IV. gas cooled fast reactor demonstrator

The preparation project aiming at the construction of ALLEGRO has been launched in 2010. CEA proposed to consider the idea of constructing ALLEGRO in Central European region based on a joint action of the Czech Republic, Hungary, Slovakia and Poland. The four members create a „V4G4” Centre for Excellence for Gas Fast Reactor studies in 2013.

General objectivesGeneral objectivesThe ultimate objectives of ALLEGRO can be summarized by:

1) Demonstration of the GFR gen-4 concept, a goal that itself can be divided into three sub-objectives, priorities between a, b and c still to be defined:

a) Qualification of the high-temperature, high-power-density, ceramic-clad , carbide fuel necessary for GFR

b) Demonstration of the technological feasibility, helium cooling and high temperature core in particular,

c) Demonstration of the breeding capacity, the ability of transmutation of actinides

2) Demonstration of heat production at industrial and economic conditions

The demonstration of the GFR concept, in its entirety, will require several steps:A first version of the ALLEGRO facility, an experimental research reactor with a fast neutron core, based on MOX fuel research experiments and qualification tests regarding new types of fuels, transmutation, high temperature materials, innovative solutions for gas circuits, etc. A second version with a ceramic fuel when availableThe questions relating to the realization of a pilot unit for fuel fabrication, associated with ALLEGRO, and reprocessing of spent fuel, remain currently open.

V4G4 Centre of Excellence - 1

A Centre of Excellence created on 18th July, 2013 among the members for supporting the research activities.Aims of the V4G4 Centre of Excellence:•to facilitate the co-operation and integration of nuclear research organisations of the V4 group (CZ, HU, PL, SK) •to perform the R&D and technology/fuel qualification tasks needed for licensing the demonstrator•to prepare the experimental program to be performed on ALLEGRO• to strengthen its scientific credibility.
