WW9715 Nuclear Safety 1997 / 1997


The VVER-1000 reactors constitute the latest generation of soviet-designed pressurized water reactors (PWR). They have been designed and built according to the requirements set out in the Russian OPB-82 safety regulations, which comply with international practices and safety standards.
The TACIS 97 program for nuclear safety contains provisions for the project referenced R2.03/97 –Part A- devoted to the development -or improvement- of reactor thermal-hydraulic safety analysis capabilities, related to the core behaviour during thermal transients. These reliable capabilities are compulsory to precisely evaluate the reactor core safety margins during normal, incidental and accidental phases, to draw possibly corrective design, and to improve accident management procedures.

These capabilities can be developed through the preparation and validation of accident management scenarios, through a numerical way and an experimental one.
The development of these capabilities will take into account the available international experience, especially from Western institutes. Thus a direct transfer of know-how from Western institutes with relevant expertise is expected.

To address the thermal-hydraulic experimental needs, a large-scale test facility called “PSB-VVER-1000” has been built at EREC, Elektrogorsk, Moscow Region.

General Description of PSB-VVER-1000 Test Facility:

The PSB-VVER-1000 test facility represents a model of a VVER-1000 V-320 reactor system. It consists of a pressure vessel housing an electrically heated rod bundle and four identical loops with all major components and safety features of the reference reactor, the 3000 MWth NPP. Experiments on the test facility are carried out in an automatic mode with use of the process control system and the data acquisition system of the test facility. It has more than 1000 measuring channels.

The PSB-VVER-1000 test facility is at present the only large scale test facility suited for the investigation of thermal-hydraulic phenomena during accident and transients in VVER-1000 reactors including the verification of related accident management procedures.

As part of the TACIS Project R2.03/97A, on this test facility, twelve experiments will be executed. These experiments are needed to validate codes and to improve the related VVER-1000 accident management procedures.


Within the framework of the project office equipment is necessary to perform the following major goals:

  • Numerous alternative pre-test calculations with use of system thermal-hydraulic codes both for the PSB-VVER 1000 test facility, and for VVER-1000 reactor for development of accident management experiments scenarios;
  • Processing and qualification of the big array of the experimental data received during modelling accident processes on the test facility and during performance of characterization tests;
  • The post-test analysis with use of system thermal-hydraulic codes of the executed experiments;
  • Revision of the accident management procedures of a reference NPP;
  • Preparation of reports and other documents requested in the framework of the Project;
  • Development of a code system for severe Accident analysis in RBMK reactors.
