Zaporozhye NPP, located in Energodar, Zaporozhye Region, Ukraine comprises 6 power units and, with 6000 MW installed capacity, is the largest nuclear power generation facility in Europe.
Background
The aim of the On-Site Assistance at the ZNPP is to transfer an operational safety culture and to support the implementation of nuclear safety improvement projects.
Background
The primary overpressure protection system is designed to protect the reactor equipment and pipelines against primary circuit overpressure phenomena during different transients.
Background
Rovno NPP located in Kuznetsovsk, Rivne Region, Ukraine comprised 4 power units thereof 2 VVER440 type reactors and 2 VVER1000 type reactors.
1) Background
The present project is a continuation of on-site-assistance (OSA), rendered by RWE Energy as the EC appointed Consultant to Zaporoshe NPP.
2) Objectives
This project had 2 main different categories of objectives and tasks:
Objectives
Objectives
In the framework of the “Tacis Nuclear Safety Programme”, it was decided to increase the nuclear safety of the units 1 through 6 at the Zaporozhye NPP by improving the protection of the primary circuit from overpressure under normal and emergency modes.

Project Description (to be included in the Database)
The aims of the On-Site Assistance at the RNPP have been:
1. to improve operational safety culture of the RNPP (Soft OSA) through general On-Site Assistance to RNPP eg.
U1.01/95 - Phase 3
Project Description
After the "Stuck-open of the pressurizer safety valve" incident that occurred in Zaporozhye in 1995, the maintenance work was incriminated and led to a modification of the geometry of valve seat and disk.

1) Background
The TACIS 96 programme for nuclear safety agreed upon between the European Commission and Ukraine contains provisions for operational safety and near term technical improvements for Ukrainian NPP.
1) Background
This contract is for the the design, manufacture, delivery, etc.
Objectives
The present TACIS project U1.01/95C aims at replacing the 12 SG (steam generator) safety valves (2 per SG) of each unit 1 and unit 2 of Rovno NPP. The new safety valves should have the following functions:
Objectives
The present TACIS project U1.01/96C aims at providing spare parts for valves for unit 3 pressuriser and pressure accumulators, which were originally supplied by German companies Sempell and Bopp & Reuther.
