Acoustic method for monitoring the state of VVER vessels

The results of an investigation of the possibility of using acoustic characteristics to evaluate the state of the VVER vessel material are presented. The investigations were performed on template–samples cut from the VVER-440 vessel material and on control samples from VVER-1000 vessels. It is shown that the characteristics of elastic waves depend on the fluence and the radiation embrittlement of VVER vessel materials.

Investigation of the partitioning of fission products between the metallic and oxide phases of melt in a VVER-1000 vessel during a serious accident

The results of investigations of the interaction of U-Zr-B-C-O melt with steel, performed as part of the OECD MASCA program, are presented. It is established that the presence of Mo, Ru, Sr, Ba, Ce, and La in the melt does not qualitatively affect the interaction with structural steel and the character of the stratification of the melt in the reactor vessel. The partition factors of the fission products between the oxide and metallic phases are determined as a function of the oxidation of the melt, the ratio U/Zr, the composition of the structural steel, and the temperature. __________ Translated from Atomnaya énergiya, Vol. 105, No. 1, pp. 3–7, July, 2008.
