Summary

Introduction of the modern neutron monitoring systems on NPPs provides more reliable control after the parameters of safety of reactor. In accordance with the requirements of normative documents modern monitoring systems allow to control such parameters of safety as reactivity and speed of its input, they are not plugged in the project of the reactor setting and control only period. Limitations of such approach are presented in the article.
Keywords: reactivity, period of reactor, neutron flux monitoring systems, SCRAM, accelerated unit uploading.
