The development of WWER monitoring and diagnostic concept

Safety and efficiency of NPP operation is ensured to a great extent by the quality of implementation of a reactor monitoring and diagnostics. A complex of monitoring and diagnostic system (MDS) is planned to be implemented in operating WWER and those which are in the design phase. MDS is designed as a complex of weakly interconnected subsystems capable of further improvements and performing the assigned functions on a full scale (therefore, a subsystem incorporates detectors, communication lines, instruments, computer facilities and software). MDS design makes provisions for step-by-step development of basic subsystems. MDS being developed is proposed to be installed gradually in all operating NPPs with WWERs. (author). 1 fig., 1 tab
