According to the Policy Statement of «Rosenergoatom»:

The management of the concern "Rosenergoatom" declares that they will make every effort to create atmosphere of openness, confidence and cooperative spirit for the purposes of safety and reli­ability improvement at the operating NPPs.

The management of the concern "Rosenergoatom" assures that the per­sonnel of the plants and enterprises directly supporting operation of the plants, will be ready to take all neces­sary and comprehensive measures for implementation of the above principles in the practical activities associated with safe, ecologically acceptable and eco­nomically efficient production of electri­cal power for the welfare of the state and people of the Russian Federation».

Safety of nuclear power plants with VVER, RBMK, EGP and BN reactors

In compliance with to the federal laws in the area of use of nuclear power, safety codes, standards and regula­tions, in 2003 extensive activities related to upgrading of plant components and systems were carried out to improve their safety level and bring to compli­ance with the current requirements.

All the major activities of «Ros­energoatom» were continued, first of all, - in the area of nuclear safety enhancement and implementation of the nuclear power plant centralized control:

- improvement of the centralized con­trol of safe NPP operation by depart­ments of the operating utility - «Rosenergoatom»;

- improvement and enhancement of efficiency of the activities at the con­cern's Emergency Response Center; effective scientific and engineering support of NPP operation by Rosenergoatom's research center - VNIIAES, other supporting research or design-and-engineering institutes;

- enhancement of the material-and- technical base and preparedness of the industry's Emergency-Engineering Center to respond to design basis and beyond-design basis accidents о enhancement of the material and technical base and improvement of operation of the training centers for operational and maintenance person­nel;

- allocating the funds for activities on NPP safety improvement from the centralized sources. The major priorities in plant operation are as follows:

- ensuring nuclear, radiation, opera­tional, fire and environmental safety, and safety precautions; о economical efficiency; о safety culture;

- compliance with safety codes and standards.

WER-type plant safety

In all the operating power units of the VVER plants a comprehensive assess­ment of the plant compliance with the current nuclear safety codes, standards and regulations were continued with the purpose of implementation of the meas­ures incorporated in the VVER Plant Safety Improvement Concepts.

Following the operating NPP safety improvement concepts, the high-priority measures were developed and are being implemented to improve the oper­ational quality and safety culture, to minimize the accident probability, and to eliminate and/or compensate the exist­ing non-compliance with the current codes, standards and regulations. The implementation of these measures will allow improving the reliability of the existing barriers and in-depth protection against radioactive releases. The meas­ures reflected in the safety improve­ment concepts are aimed at resolution of the following basic, safety-relevant challenges:

- diagnostics of the main equipment and pipe metal conditions, implemen­tation of the non-destructive metal testing methods;

- replacement of the obsolete equip­ment;

- minimization of the common-cause failure probability;

- improvement of the operational and accident management procedures;

- upgrading of the safety important systems in order to improve their reliability.

The safety improvement concepts are systematically implemented in the framework of the NPP upgrading and renovation programs.

A result of implementation of a set of upgradings was the lifetime extension of the Novovoronezh-3 and 4, and the Kola-1. The justification documents were prepared for the lifetime extension of the Kola-2.

During the life cycle of the nuclear power plants, «Rosenergoatom» inspects and assesses the safety level at all the NPP units, as stipulated by the Nuclear Safety Convention. The obtained results demonstrate that at all the operating VVER-type NPPs an acceptable safety level is maintained, and measures aimed at their continued reliability and safety improvement are taken.
