The SO controlled parameters do not exceed the established reference levels.

Since the start of 2010 no record violations (accidents, incidents) at the ChNPP have been registered.

The main activities being performed at Power Units and Industrial Site:
• At 3rd Power Unit the activities on the Unit’s release from spent nuclear fuel are in progress. In total, starting this year, 891 spent fuel assemblies (SFA) were transported from the Unit to ISF-1. 134 SFA remain at Power Unit 3 in near-reactor cooling pools. The activities are performed according to the schedule approved by ChNPP Order No. 36 of January 22, 2010.
The release of Unit 3 from the fuel is accompanied by own production of “short” jerry cans required to store the SFA at ISF-1. 379 “short” jerry cans out of 400 required have been produced since the beginning of the year.
• Since June 05, 2010, the Industrial and Heating Plant (IHP) is under preventive maintenance. According to the schedule the repair activities completion is planned for July 12, 2010. The IHP will be operated only in case of additional financing required for the procurement and transportation of natural gas in accordance with the established procedures.
• Within the framework of preparation to 2010-2011 autumn-winter period the activities on inspection and repair of internal heat supplying systems of buildings and constructions are also in progress. Deadline – September.

The main activities being performed at Shelter Object:
• Under Project “Site Preparation for NSC Construction” the activities on excavation of trenches for the NSC foundations (South and North lines) are being performed on a twenty-four hour basis. The project deadline – July 2010;
• Under Project “Construction of SO Fire Protection System” the activities are being carried out according to the schedule. The project deadline – January 2012;
• Under Project “Creation of SO Integrated Automated Monitoring System (SO IACS)” the activities are being performed according to the schedule. The project deadline – September 2010;
• Under Project “Upgrades for SO Physical Protection and Access Control” the activities are being carried out according to the schedule. The project deadline – September 2010.

The main activities on decommissioning projects:

WANO Mission - by Information Department 25/06/2010 - 11:33

On 22-24 June 2010, WANO Technical Assistance Mission was held at ChNPP to exchange the decommissioning experience.

Mr. Andrey Nosov (WANO Moscow Center), Mr. Jeremy Hunt (Sellafield Ltd., Great Britain), Mr. Markus Birkholz (Greifswald NPP, Germany), Mr. Thomas Reinke (Greifswald NPP, Germany), and Mr. Valery Kotovich (Nord NPP, Germany) participated as mission experts.

Chernobyl NPP specialists provided information on current situation on ChNPP Units decommissioning, main decommissioning problems and methods to be applied for their solving.
In turn, the mission experts prepared the presentations under topics being interested to Chernobyl NPP specialists. Thus, German colleagues shared the experience in creating Decommissioning Management System (DeManS), decommissioning information preservation, planning and performing dismantling activities at Turbine Hall. The expert from Great Britain provided presentation, which is especially interested for ChNPP experts as it regards core survey issues, fuel retrieval, remote decommissioning of contaminated buildings and equipment, dismantling of ventilation stack, etc.
During the final meeting, WANO experts provided Chernobyl NPP specialists with preliminary recommendations to improve their activity. The final mission report will be distributed among ChNPP managers and specialists to analyze and take appropriate decisions.

WANO experts and mission participants noted that further improvement of decommissioning process at Chernobyl NPP is required as its efficiency mostly impacts on NPP safety.

For reference. The World Association of Nuclear Operators (WANO) was established on May 15, 1989, in Moscow city by the operators. Chernobyl NPP accident in 1986 became a prerequisite for the Association establishment. The accident became an obstacle to promote nuclear energy technologies at the world’s energy market and forced to critically revaluate safety level of all operating NPPs and those being under construction worldwide. According to WANO Statute, a membership in the association is achieved on voluntary participation base, openness, confidence among all association members.

WANO Mission is an organization of sharing the experience in power units operation, obtaining of recommendations on their safety and reliability improvement using advanced international experience, comparison of NPP operation results and following the example of the best operators.

Chernobyl NPP (ChNPP) is WANO member since its foundation. It enables the plant personnel to apply in their practice the experience of other NPP colleagues, participate in workshops, technical visits organized by the association, achieve positive results in decommissioning of ChNPP Units, Shelter transformation into ecologically safe system, as well as raise a level of needed knowledge.
