Digital Library of Periodicals of National Academy of Sciences of UkraineРезюме: | The paper is devoted to the theoretical study of Coulomb explosion in silicate
glasses with low ionization potential under internal alpha-irradiation.
The phenomenon was studied in the way of computer simulation, namely
by the molecular dynamics (MD) method; parameters of the so-called lavalike
fuel-containing materials (LFCM), were chosen as input parameters
for the model due to its practical importance. LFCM are high-radioactive
glasses, which were formed during an active stage of a well known heavy
nuclear accident, occurred on Chornobyl NPP in 1986. Computer simulation
revealed that Coulomb explosion really may occur in the LFCMs and
leads to additional radiation damages under internal alpha-irradiation. The
total quantity of atomic displacements produced in the way of Coulomb explosion
from each alpha-particle track is 40000 to 80000, which exceeds
radiation damages from alpha-particle and heavy recoil nuclei altogether
(about 3500) more than one order. |
