The longterm material research project of ALVEL entered its PIE stage after shipping first two batches of irradiated samples from Temelin NPP to hot cells in ┌JV Řež in April 2019.
Project is focused on irradiation induced grouwth of currently used and perspective Zr based alloys and irradiation induced creep of E110 cladding tubes under real VVER operating and water chemistry conditions.
It is implemented by ALVEL in cooperation with Škoda JS, ┌JV Řež and CVŘ for Bochvar Institiute of Anorganic Materials in Moscow and ČEZ - Czech utitlity company as main Customers.
It started from Conceptual design and licensing phase in 2012-2013. The total of six Material Cluster Assemblies (MCAs) were manufactured and delivered by TVEL and loaded into TemelÝn Unit 1 reactor core in 2014.
One MCA is unloaded from the reactor each year and after necessary cooling time shipped to hot cells for evaluation by experienced staff of CVŘ and ┌JV Řež using the State-of-Art facilities built in the frame of the SUSEN Project.
