The assumed cause of the emergency power cut-off is the damage of Phase B of current transformer air circuit breaker V-330-Lesnaya with the subsequent inflammation.
The current transformer’s damage resulted in fall of Phase B of air circuit breaker V-330-Lesnaya. The damaged area was localized by backup protection actions. The inflammation was eliminated. There were no injuries. The investigation is underway under the established procedure.
As on February 4, 2014, seven dismantled blocks of VS-2 were completely fragmented on specific-equipped site. Consequently, 1,599 fragments became available, which were transferred to Unit 3 Turbine Hall for temporary storage.
For information. VS-2 dismantling works were carried out under extremely complicated radiation conditions since end of October till beginning of December 2013. Totally, 330 tons of supports and braces of the ventilation stack were dismantled.
On January 27, a regular session of the Slavutich Town Council was held, where deputies made elective resolution to prepare joint statement of the representatives of all factions represented in the town council regarding social and political situation in Ukraine and Slavutich. First of all, the statement was addressed to the managers of international projects being implemented currently within Chernobyl NPP site, and to ChNPP Management as well.
By this statement, the representatives of local government confirm that territorial community of Slavutich is able to control the situation and guarantees security for the international project stakeholders during their stay in the town.
During January 29-30, 2014, additional training of operational personnel of ICSRM and instructors of the Training Center in functioning of ICSRM Radiation Record-Keeping and Monitoring System was provided on SSE ChNPP site.
The training was arranged by NUKEM Technologies GmbH under the Contract of European Commission to support ICSRM hot testing.
The mission is a continuation of activities performed during 2013 in relation to studying possibility of using GEOSIL geopolymer as binding material for RAW immobilization. This technology is successfully used for immobilization of ion-exchange resins and sludge at A-1 NPP and V-1 NPP (Bohunice, Slovakia).
Preliminary results of investigations conducted at ChNPP have confirmed possibility of using geopolymers in radioactive waste immobilization technology. At this, waste filling in GEOSIL matrix, while meeting the waste package acceptance criteria at the Specially Equipped Near-Surface Solid Waste Storage Facility (SENSSWSF), exceeds the waste amount in cement matrix specified by the technology of ChNPP Liquid Radioactive Waste Treatment Plant. This would enable to reduce amount of RAW packages being produced meeting the requirements of normative documentation applied in Ukraine, and IAEA recommendations on radioactive waste management.
On January 22, 2014, the IAEA expert mission started at Chernobyl NPP to review a design of technical specification for upgrading of RAW incineration facility of the Solid Radioactive Waste Processing Plant (SRPP).
Upgrading of incineration facility assumes the creation and inclusion of additional waxing unit into SRPP process flow to carry out technological operations relating to mixing a non-combustible product, resulted from RAW incineration, in the form of ash and cinders with a wax prior to its compaction.
On January 20, 2014, the Minister of Ecology and Natural Resources Oleg Proskuryakov has conducted phone negotiations with the Director of Nuclear Safety Department of the European Bank for Reconstruction and Development Vince Novak.
Representative of Chernobyl Shelter Fund in Ukraine Alexander Slavis, Chairman of the State Agency of Ukraine for Exclusion Zone Management Vladimir Kholosha and Head of International Relations Directorate of the Ministry of Ecology and Natural Resources Mikhail Kamasa participated in the negotiations.
The parties discussed the issues of cooperation between Ukraine and EBRD regarding the activity of Chernobyl Shelter Fund, progress in negotiations with the contributors in relation to international projects funded from Shelter Fund assets, Nuclear Safety Account and the contributions.
Oleg Proskuryakov and Vince Novak confirmed that nowadays the highly positive dynamics and the consistency are achieved in cooperation for the purposes of Chernobyl NPP issues.

According to the results of the personnel dosimetry control averageannual exposure dose per Chernobyl NPP’s worker in 2013 was 1.98 mSv. In 2012 - 2.2 mSv.
Collective dose based on 2504 Chernobyl NPP workers in 2013 was 4956.8 m*mSv, whereas in 2012 - 5800.56 m*mSv.
