Comprehensive tests of the crane trolley with hoist and grips are ongoing at ISF-2 (Chernobyl NPP dry spent fuel storage facility). The crane trolley with hoist and grips (CTHG) will be used jointly with the hot cell (HC) crane to transfer hot cell equipment.
All procedures are performed in accordance with the Testing Program approved by the State Nuclear Regulatory Inspectorate of Ukraine.
The ability to remove and transfer HC equipment (an apparatus to cut spent fuel assemblies, equipment to replace a disk of the cutting device of this apparatus, sliding holder components, system of the double cover of the fuel cartridge, video cameras, power manipulators), as well as the ability to prevent jamming of sliding holder components are checked during the tests.
The possibility of remote (using manipulators and CTHG without personnel access to HC) dismantling of HC equipment, its transfer from HC to decontamination and maintenance areas, backward transfer to HC, remote installation and operability after installation is checked.
According to SNRIU instructions, representatives of the State Scientific and Technical Center for Nuclear and Radiation Safety, who monitor the progress of the tests, participate in these tests.
According to SSTC NRS expert Mykola Sapon, the possibility of remote dismantling of CH equipment and its remote reinstallation, without personnel access to HC are very important operations in terms of the possibility to avoid additional personnel exposure.
“The test results generally confirm CTHG ability to perform the established functions jointly with other hot cell equipment at ISF-2. At the same time, it will be possible to speak about completely positive results of the comprehensive tests only after considering the comments made the tests”, Mykola Sapon commented.
