FIELD: power industry.
SUBSTANCE: control method of operating parametres of radiation zone of nuclear reactor operating on water under pressure, which involves the following: data acquisition stage (FB, FH, "ТВГ", TBX, Q), which characterises operating conditions of radiation zone of reactor; evaluation stage of real values (T av. real, AOr, 
max real) of operating parametres at least depending on the obtained values (FB, FH, "ТВГ", TBX, Q); selection stage of control law of concentration of absorbing compound ([B]) and positions of introduction (Z1-Z5) of groups of rods (P1-P5), which is chosen at least between the first and the second control laws differing from each other; and control stage of operating parametres by means of chosen control law depending on the set values (T av. set, AOset max set) of those parametres and from real values (T av. real, AOreal, 
max real), which have been determined as the result of evaluation.
EFFECT: improvement of the method efficiency.
