On the possible physical mechanism of Chernobyl catastrophe and the unsoundness of official conclusion

The official conclusion about the origin and mechanism of the Chernobyl catastrophe is shown to essentially contradict experimental facts available from the accident. In the frame of existing physical models of nuclear fission reactor, it is shown analytically that under conditions of the accident the period of runaway of reactor at the fourth power generating unit of the Chernobyl Nuclear Power Plant (CNPP) should be either 10 times slower or 100 times faster than that observed. A self-consistent hypothesis is suggested for the probable birth of magnetic charges, during the turbine generator test under it's own momentum test, at the fourth power generating unit of CNPP, and for the impact of these charges on the reactivity coefficient.
