原始语种摘要: The method of cluster dynamics (CD) is used to simulate the effect of the change in temperature of reactor pressure vessel on the time evolution of point defect clusters and the induced neutron embrittlement of $\alpha$-iron in a research nuclear reactor BR-2 (Mol, Belgium). For the two temperature regimes, the irradiation times, which provides the qualitatively change of the mean size and number density of self-interstitial atom clusters (SIAC) and vacancy clusters (VC), are found. Temperature is chosen of 573 K during all irradiation time at the first regime. Temperature is grown from the room one (288 K) to the value of 573 K during the start of nuclear reactor operation mode with time length about 381 hours; thereafter it does not change during next $\cong$ 14 days; then, at the...
