The activities are performed by “Ukrtransbud” Corporation.
    Over a period passed from the contract awarding, the Contractor performed the design works, all necessary permissions from the regulatory bodies were obtained, the preparatory works were executed, and the crane of large load capacity was commissioned.

    The SSE ChNPP Radiation Safety Shop carried out the radiation survey of VS-2. The continuous radiation monitoring within the work execution area are underway by this Shop.
    The dismantled fragments of VS-2 will be placed for temporary storage at Unit No.3 Turbine Hall’s premises. This Power Unit after removal of spent nuclear fuel has a status of radioactive waste management facility.

     

     

    The State Nuclear Regulatory Authority of Ukraine issued to the SSE ChNPP a separate authorization for operation of ChNPP II Generation New Ventilation Stack (NVS).

    According to this document the SSE ChNPP is allowed to operate the New Ventilation Stack and associated systems of the ChNPP II Generation provided that the strict control over the state of the NVS building structures is performed in accordance with the Regulations.

    For your reference: The Contract on construction of the New Ventilation Stack and associated systems of the Chernobyl NPP II Generation was signed on July 15, 2010, with the Russian-Ukrainian Consortium “Ukrytiye”(CJSC “Atomstroyexport”, Russia, and CJSC “Ukrenergomontazh”, Ukraine), as with the winners of the competitive tender carried out by the EBRD. The Project is included into the International Technical Assistance Program of Shelter Object Transformation into an Ecologically Safe System (SIP) financed at the expense of the Chernobyl Shelter Fund administrated by the EBRD.

    The NVS represents a metal tower 50 m in height (125 m from ground level) with a gas vent pipe 6 m in diameter located inside it. It was installed at the existing reinforced-concrete structures of the Chernobyl NPP II Generation main building and equipped with the radiation monitoring system and light fencing system. The NVS is commissioned instead of the existing Ventilation Stack (VS-2) to be dismantled in the nearest time.

    WANO Technical Support Mission is completed at Chernobyl NPP, which took place since 15 to 18 October. The event was held at the request of ChNPP and was devoted to Safety assurance problems during preparation of uranium- graphite units for long-term storage under supervision (preservation).

    The purpose of the mission in the first turn, was to share experience and knowledge in the field of NPPs decommissioning, as well as review of approaches and technologies, used in the uranium-graphite reactor decommissioning and optimization of ChNPP Units decommissioning strategy.

    On October 11, the inactive comprehensive tests at Liquid Radioactive Waste Treatment Plant (LRTP) using LRW simulator have been completed. According to a testing programme, four recipes were practiced, i.e. treatment of evaporated concentrate, ion-exchange resin, evaporated concentrate resin, and perlite.

    The testing had positive effects and currently the deliverables are being prepared. The prepared document package is planned to submit to SNRIU in early November to obtain a separate permit for LRTP commissioning (performing active tests using actual liquid radioactive waste).

    According to a schedule, the active comprehensive testing is supposed to commence in the first half of December 2013.

    On the 11th of October 2013 the third lifting of the Arch was successfully completed.

    The third lifting differed a bit from two previous operations, as it included several stages. The first stage – jacking of the Arch for the height just a little more than 110 meters (higher than the design position) – was performed during September 14-16, 2013. By doing so the Arch weight was completely transferred to the jacking systems. During a period from September 17 the final assembly of side segments of the Arch, as well as of its supporting parts, was done. Simultaneously, skidding tracks and other auxiliary constructions were installed at the Erection Zone foundations.

    The works on commissioning of New Ventilation Stack (NVS) and Generation II auxiliary systems are being continued at Chernobyl NPP.

    During September, the Main Building and Outdoor Facilities Operation Shop implemented the first two stages, i.e. pilot operation and acceptance testing of NVS. During work performance, a continuous monitoring of volumetric air activity around Shelter Object was ensured when changing the modes of ventilation systems and shutting the Ventilation Stack 2 (VS-2) orifice, the test logs of aerodynamic characteristics and radiation parameters of NVS discharges are finalized.

    On October 7-8, 2013, a delegation of Ignalina NPP (Lithuania) Management headed by the Director General Darius Janulevicius has officially visited Chernobyl NPP.

    Chernobyl NPP and Ignalina NPP are the nuclear power plants. Therefore, as Darius Janulevicius said, the priority of the visit is to share the experience gained by both enterprises for a period since their final shutdown.

    The official visit agenda was diversified enough. The guests got familiar with a decommissioning concept accepted at Chernobyl NPP, with the changes of organizational structure and the options of personnel motivation required for improvement of process management. In return, the Lithuanian delegation members provided also a presentation regarding Ignalina NPP decommissioning progress.

    Contrary to Chernobyl NPP, for the Units of which a deferred dismantling strategy is accepted, Ignalina NPP follows an immediate dismantling, when equipment is dismantled almost immediately following reactor shutdown. Hence, the delegation members were interested specifically in experience regarding organization of dismantling activities, as well as procedure and process of releasing the dismantling waste from regulatory control.

    During the tour, the guests visited the facilities for radioactive waste management located within industrial site and got familiar with NSC construction progress.

    At the end of the visit, Darius Janulevicius pointed out that during the meeting the representatives of Ignalina NPP have heard many valuable comments and remarks, which they would try to address in their future activity. “Our processes go forward almost in parallel. We keep ahead of you in some issues, and you do it in other ones, but we have different decommissioning strategies and, in common sense, we all are pioneers dealing with decommissioning of RBMK reactors. I am sure that such close bilateral cooperation would be very useful to enhance the efficiency for solving important and unique tasks, which our enterprises deal with”, the Director General of Ignalina NPP emphasized.

    During September 15-16, 2013, the first stage of 3rd lifting of the NSC Arch’s Eastern part was performed at the Shelter Object site. The structures with total weight of 9,986 tons were lifted for 26.5 m height.

    At the moment the installation of the Arch’s segments and activities on preparation for the second stage of lifting are in progress at the site. Total weight of the Arch to be lifted will be 11,516 tons. Completion of activities on the second stage is planned for October 2013. Following completion of the lifting works, the Arch’s Eastern part will reach the design height and will be moved towards the Shelter Object. The works on assembling the metal structures of the Arch’s Western part will commence at the emptied site.

    The New Safe Confinement (NSC) as a multifunctional facility with a design life of 100 years in future will enable to perform the removal of the fuel containing materials, being in the Shelter Object, and their conditioning for subsequent safe storage.
