Comparison of microstructural features of radiation embrittlement of VVER-440 and VVER-1000 reactor pressure vessel steels

Journal of Nuclear Materials, 2002
Comparative microstructural studies of both surveillance specimens and reactor pressure vessel (RPV) materials of VVER-440 and VVER-1000 light water reactor systems have been carried out, following irradiation to different fast neutron fluences and of the heat treatment for extended periods at the operating temperatures.

VVER-440 and VVER-1000 Reactor Dosimetry Benchmark—BUGLE-96 Versus ALPAN VII.0

Journal of ASTM International, 2012
Analytical results of the vodo-vodyanoi energetichesky reactor-(VVER-) 440 and VVER-1000 reactor dosimetry benchmarks developed from engineering mockups at the Nuclear Research Institute Rez LR-0 reactor are discussed. These benchmarks provide accurate determination of radiation field parameters in the vicinity and over the thickness of the reactor ...

30th anniversary of VVER-1000 startup

Atomic Energy, 2010
The first power-generating unit with VVER-1000 was brought on line at the Novovoronezh nuclear power plant on May 30, 1980. The history of VVER-1000 development is briefly recounted. The possible goals and paths for further development of light-water vessel reactor construction in nuclear power in Russia are briefly examined.

VVER-1000 SFAT

2002
IAEA needed a rugged spent fuel attribute tester, SFAT, for verifying spent fuel assemblies of the Ukrainian VVER-1000 reactors in line with IAEA safeguards measurement standards and criteria of verification. Spent fuel verification using the existing Improved Cerenkov Viewing Device is becoming more and more difficult and sometimes impossible ...

Monitoring of the VVER nuclear reactor internals

Nuclear Engineering and Design, 1997
Abstract This paper presents a review of the published pressurized water reactor accidents caused by internal vibrations. These accidents are evaluated with respect to their impact on the safety and economy of nuclear power generation. Subsequently, criteria for a monitoring system which would allow the prevention of such accidents are proposed ...

Advanced process simulation with APROS for VVER-91, the next generation reactor design for VVER-1000

1997
The paper describes the capabilities of APROS code in the simulation of the VVER-91 concept. The VVER-91 models realized with APROS are described and a short overview of the various types of analysis performed is given. Particular emphasis is paid on the ATWS analyses performed with APROS.

Defence in Depth of VVER-440 Reactors

2011
Defence in depth is one of the most important principles, since it underlies the safety technology employed in nuclear power plants. All safety activities, whether organisational, behavioural or equipment-related, are subject to layers of overlapping provisions which are designed to ensure that if a failure should occur it would be compensated for or ...
