RESUMO

A nonstationary problem of thermal interaction of a hot spherical particle and surrounding water is being solved for conditions of heavy accident at a nuclear reactor. In calculation of heat transfer through a vapor gap thermal radiation of a particle is taken into account. For the initial stage of interaction, an analytical solution is obtained in isobaric approximation; comparison with a full numerical solution has shown that oscillations of vapor pressure and vapor-gap thickness do not influence mean parameters of heat transfer from a particle to water. Results of the damping effect of thermal radiation of a particle on oscillations of particle vapor envelope are obtained. Possible destruction of a melt drop under the influence of pressure fluctuations in the vapor gap is evaluated and the size of a drop is determined at which its further destruction is impossible.
