Methods and means of ensuring the accuracy of bending deformation measurements of connecting pipe between the VVER reactor and the steam generator in the conditions of a fuel campaign

Глобальная ядерная безопасность
The welded joint zone (WJ) No. 111 is a welding unit for the "hot" collector of the primary coolant to the DN1200 steam generator nozzle. The experience of operation of steam generators PGV-1000M of NPP power units with VVER-1000 shows that the WJ zone ...

Investigation of Coolant Mixing in Reactor VVER-1000

, 2011
We present an experimental investigation of coolant mixing in downcomer and lower plenum of VVER-1000 here. The arrangement of the problem, the methodology and results are discussed. Three groups of experiments simulating coolant mixing were executed: in conditions of RCP start-up, during natural circulation recovery in the course of SB LOCA and in ...

Energy deposition analysis for VVER‑1000 core internals

Nuclear Power and the Environment
Calculation of energy deposition in metal structures under the influence of reactor irradiation is an important task in analyzing the state of reactor pressure vessel (RPV). Correct determination of energy deposition is important for obtaining initial data for assessing: temperature fields in the RPV, radiation swelling of the RPV material, and changes
