Monitoring and control of nuclear steam generating plants including fast reactors

The main attention is paid to one aspect of the computerized systems' creation problem, namely, to the development of specific system's functions concerning monitoring and control. That is, first of all, the regimes' optimization aimed at reducing equipment damageability, at improvement of safety. The possibility is considered for improvement of neutron flux monitoring during refuelling aimed at control rod movements' detection, as well as possibility of lowering thermal stresses when realizing the protection in the regimes with violation of normal operating conditions including the loop isolation. The possibility and purposefulness of using computer systems for this task as well as for control of the plant residual heat removal system, for the plant startup and shutdown are considered. The developments are mentioned concerning the operator's advisor system as well as questions of the system's distributiveness. (author). 3 figs
