Prospective opportunities for small and medium size reactor utilization in the Armenian National Grid

The use of reactors of commensurable power in Armenian National Grid is economically and ecologically expedient. However, the commensurability of nuclear units with the operating capacity of the whole power system (in a series of regimes the capacity of NPP can reach 60-70% of operating capacity of the power system) dictates the necessity for carrying out the special researches of survivability of the power system, in connection with the reciprocal influence of emergency perturbations in the power system on parameters of operation of technological systems of the NPP, and vice versa.
