According to the results of a comprehensive analysis, it was found that the nuclear safety monitoring system (NSMS) does not fully comply with the requirements put forward to it. By assessing the sufficiency of the detection points of this monitoring system, it was found that there is no monitoring at the cluster of nuclear fissile materials (NFM) in the central hall and at the "northern" cluster in 305/2 rooms. The effectiveness of monitoring the "southern" cluster of NFM in the room. 305/2 is insufficient and does not comply with the standards regulated by the rules of nuclear safety. Also, a number of other requirements to the NSMS (as the emergency alarm systems of the spent nuclear waste storage facility) are not fulfilled. It is proposed to re-arrange the measuring channels (MC) of the system, decommission excess (non-informative) MC and use their equipment to organize new effective monitoring points; to upgrade the software and arrange individual ground of the system to reduce the influence of high-frequency interference.
