Central Institute of Design and Technology (CPTI JSC, an enterprise of Rosatom's TVEL Fuel Company) has been awarded and has signed the contract for supply of refuelling machines (RM) for Units 1-4 of Akkuyu NPP which is being constructed by Rosatom Russian State Corporation in Turkey, based on Russian project.
The Employer is TİTAN2 IC İÇTAŞ İNŞAAT A.Ş., a Turkish-Russian joint venture established by CONCERN TİTAN-2 JSC (an enterprise of Rosatom) and IC İÇTAŞ INŞAAT SANAYI VE TICARET A.Ş., for construction of Akkuyu NPP.
Under the contract, CPTI will provide development of the technical documentation, supply RMs for each power unit at Akkuyu NPP, and installation. The equipment will be manufactured in Russia.
Refuelling machine is designed for nuclear fuel loading and replacement of spent fuel with fresh fuel assemblies during the operational cycle of a power unit. RMs are used for operations with nuclear fuel assemblies and absorbing rods of the reactor’s control and safety system, as well as for fuel cladding failure detection.
The machine is mounted on the hermetic vessel of the reactor building above the fuel storage pond and reactor pit. The total weight of the assembled RM will be approximately 55 tons.
CPTI has already begun to develop the technical project and necessary design documentation for manufacture of the RM for the Power Unit No. 1 of Akkuyu NPP - its supply is scheduled on 2022. The equipment supply for all four power units is to be provided by 2025, completion of installation - by the early 2026.
