| Popis: | Pool scrubbing occurring in the containment of a nuclear reactor is an important mechanism for radioactive particle removal. In this article, an approximate analytical solution to the equation of particle removal with any possible combination of removal processes is suggested. Assuming that the particle size distribution can be approximated by a log-normal function, the reduction of total particle number and mass, and the changes in average particle size and polydispersity are expressed as explicit functions of their initial values, time, and the removal mechanism parameters. The solution is then applied to a pool scrubbing problem as an application example. The approximate solution derived in this study shows good agreement with the exact solution. The error, caused by an approximation for the slip correction factor, is potentially large only for the intermediate-size particles. However, the absolute error still remains small because the particle removal rate is minimum in that size range. The me... |
