One gasoline channel (FC) and one channel of management and safety system (CPS) had been faraway from the Unit 1 reactor. These works are carried out with a analysis function within the framework of working documentation improvement for the the second stage of the Project “Chernobyl Units 1, 2, three Final Shutdown and Preservation” (FS&P). Dismantling and processing of the channels has sensible worth for willpower of length for decommissioning actions, preservation and secure enclosure of reactors.
Estimated time period for FC & CPS channels dismantling and processing, in accordance with the “Program of Units 1, 2, three Shutdown & Preservation Stage implementation” permitted by SNRIU, till 2028. The Stage length is set, particularly, by the point of works execution in every of three reactors, containing from 1661 to 1693 FC and 227 CPS channels.
It is assumed that eliminated FC and CPS might be fragmented on the modernized Long Length Waste Cutting Facility (LLWCF), the place particular objects might be dried, fragmented, packaged within the overpack, obtained packages might be characterised and loaded into transport containers. The length of dismantling works and particular objects processing is set by LWCF capability: inside someday and evening (two twelve-hour shifts), solely 2 channels could be processed on the Facility.
“Due to delay in implementation of the Project Creation of a Modernized Long Length Waste Cutting Facility at Chornobyl NPP we’re pressured to search for methods to hurry up the work. In specific, length of lengthy size waste slicing course of could be diminished by eradicating from the method operations on particular objects drying and by decreasing the variety of transport operations, because the technical circumstances established at ChNPP throughout decommissioning enable to make applicable adjustments to beforehand permitted technical options”, — famous Vladimir Peskov, Deputy Technical Director for Operation.
In addition, because the work on FC and CPS channels elimination was carried out in giant scale at Chornobyl NPP throughout operational Units repairs, that’s, within the 90’s of the final century, these works will assist to determine the extent of expertise of the employees concerned within the work, dose load, in addition to availability of the required tools for particular objects retrieval from the reactor. “There should not many specialists on the plant who’re succesful to carry out these works. Consequently, the switch of expertise in efficiency of the channels retrieval from skilled employees to younger folks, is an important a part of at this time’s exercise”, — emphasised the Deputy Technical Director.
