Dismantling Completion of Turbine Hall Light Roof within NSC Under-the-arch Space

16 February 2018

Completion of this task significantly improves fire safety of the New Safe Confinement.

The sections of potentially inflammable roof of Turbine Hall located in the area of Arch End Walls within axes 60-62 and 38-40 were dismantled under the project of NSC enclosing perimeter which was completed by construction at the end of 2017.

In the first half of February 2018, three sections within axes 52-54, 56-58 and 60-62 were dismantled. Consequently, the whole area of the roof defined by the design was dismantled.

The work was carried out with two cranes whose lifting power makes 300 and 270 tons. One of them was positioned on the pioneer wall and the other one - to the north of Shelter Deaerator Stack within the NSC temporary storage area.

Currently, the activities associated with cutting the dismantled structures and their removal to specially equipped area for their storage are underway. The dismantled slabs are decontaminated if necessary.

As of February 15, 2018, about 15 % of the dismantled slabs have been removed.

During the work period, the reference levels of external exposure (13 mSv) established for the NOVARKA (Contracting organization) personnel were not exceeded. No emergencies or incidents were recorded.

At ISF-2 preparation for the on-site transport container HI-TRAC-H testing is underway

15 February 2018

A series of technological operations was hone to perfection as part of the preparation for the on-site transport container (OTC) testing. In particular, 71-tons OTC was installed on the trolley for the canisters handling and transportation system, after that OTC was delivered to one of the premises of the facility for Spent Fuel preparation for storage. Further using the the crane with loading capacity of 125 tons, OTC was lifted to the vertical position and moved to one of the special carriages.

OTC HI-TRAC-H is the most important equipment ensuring the safety during Spent Nuclear Fuel handling at ISF-2, it performs the radiation protection functions for the personnel and provides heat removal during operations for SNF drying, DWSC filling with helium and DWSC welding, transportation and loading into concrete storage module. This is one of the key elements of the temporary dry storage system implemented at ISF-2 for ChNPP's RBMK-1000 Spent Nuclear Fuel long-term temporary storage.

Chernobyl NPP starts transportation of treated RAW for disposal

01 February 2018

Transportation and handover for disposal of RAW packages produced at the Liquid Radioactive Waste Treatment Plant (LRTP) into the Engineered Near-Surface Solid RAW Disposal Facility (ENSDF) commenced on January 31. The first batch in this year – four packages of RAW – was transported to the disposal facility. The further handover of RAW packages to the ENSDF is to be implemented according to the schedule approved between the Chernobyl NPP and State Specialized Enterprise "Central Enterprise for Management of Radioactive Waste" (SSE “CEMRW”) to which the ENSDF belongs. The available RAW packages are transported to make room for the end product storage at the beginning of LRTP operation.

As noted by the Deputy Technical Director (for RAW Management) Oleksandr Skomarokhov, at the beginning of 2018 the Chernobyl NPP has approached the final stage of LRTP commissioning: “A separate permit for the LRTP operation was given to the enterprise in December 2014. Before that all required tests of the LRTP had been carried out. These tests resulted in production of 63 packages with RAW. Four packages were transported to the ENSDF in 2014 to fulfil the whole processing chain of RAW management. Other packages were stored at the LRTP within the end product curing premise in accordance with the permissions of the State Nuclear Regulatory Inspectorate of Ukraine (SNRIU)”.
