Conclusions

  1. 1.

    Dynamic investigations and calculations performed on the basis of experimental data on static operation indicate that the large value of the power coefficient of reactivity, resulting from the high volumetric steam content, is the main reason for the occurrence of instability in the operation of the VK-50 reactor. The resonance properties of the natural-circulation loop or its individual components play a secondary role.

  2. 2.

    The damping coefficient of the correlation function of the fluctuations in the neutron power may be effectively used for predicting the stability limits.

  3. 3.

    The experimentally obtained limiting power values yielded valuable information for correcting the theoretical instability model, which makes it possible to extrapolate the data obtained to the region of higher pressure values.
