ROVNO NPP (RAES) is composed of 3 reactors in operation (2 WWER 440/213 and 1 WWER 1000/320). EDF decided to join the EC effort on improvement of design and operational safety and conduct the whole project, particularly to permit development of the on-site presence of a significant team, which is considered as necessary condition for the implementation of an in-depth work program.
This programme aimed at improving the following areas at Rovno NPP:
- Operating and monitoring conditions
- Design nuclear safety level
- Nuclear safety organization during operations.
This is the continuation of General On-site assistance project U1.01/95 that started in November 1997. EDF continued operational assistance to Rovno NPP that involved above mentioned safety improvement areas. Similarly to U1.01/95, several technical methodological exchanges were organised by the EDF OSA team with Rovno NPP engineers and technicians.
Improvement of operating and monitoring conditions involved activities linked with procurement procedures. The four selected action within TACIS 94 through 96 programmes using all the funds available were defined as its first priority and included the following:
- Automatic radiation monitoring system "ASKRO" (U1.01/96B).
Improvement of design nuclear safety level involved development of Safety improvement report which presented an exhaustive programme of action that must be performed, with prior justification in order to reach a sufficient safety level, considering:
- Replacement of Steam Generator Safety valves for Unit 3 (U1.01/96A)
- Maintenance of safety related valves (U1.01/96C)
- Shock absorbers spare parts (U1.01/96D).
Improvement of Nuclear safety organization during operations and maintenance involved necessary actions to improve operating methods and practices by an active transfer of operating experience of EDF. The main tasks were:
- review of operational and emergency operating procedures,
- implementing quality assurance organization,
- implementing work and organization of maintenance.
Further information on the project results could be sought from the beneficiary organizations.
