A comparison of RBMK and BWR reactor parameters is presented in Table 1.3. It is worth noting that these reactor types [2] are quite similar in power per fuel quantity or fuel rod length, but large differences appear when comparing reactor power per core volume. The power of the RBMK reactor is somewhat less in that respect, and its heat capacity is correspondingly larger. These parameters have a certain impact on the operation of the reactor during an emergency.
