Completed Conversion of the LVR-15 Research Reactor
Original language description
LVR-15 is 10 MW pool-type LWR research reactor situated in the Research Centre at Rez near Prague, Czech Republic. Since February 2010 the reactor had successfully undergone a conversion from HEU IRT-2M fuel to LEU IRT-4M fuel. The conversion had been planned to be finished in March 2012 after 23 cycles (K116 ? K138) using mixed cores with both types of fuel. Based on the agreement with US DOE the conversion plan was changed in spring 2011. The reason of the change was reasonable acceleration of the future return of spent IRT-2M fuel back to Russia. Based on the new plan, the last cycle using HEU fuel was operated in July 2011. After that, during summer 2011, the reactor obtained permission for the re-entry into the operation after refueling from the Czech regulatory body. Based on the permission the criticality experiment using both spent and fresh FAs IRT-4M was performed in September 2011 and the first criticality was achieved with a compact configuration in 12th September 2011.
