The Control Method When Loss of Convention Island Instrument Control Air Source at Full Power
ZHANG Jun;Hainan Nuclear Power Co.,Ltd. Opration Department;
The purpose of this article is to study the response of each critical systemin compressed air for instrument control in the case of loss of conventional island and concluded that the condition on a circuit has impacts on the secondary circuit system and the BOP system, eventually master of nuclear power plant operators to take the most effective and feasible method of operation and sequence of Control to control the State of nuclear power units. Operator through specific procedures of this condition in the process of stopping of steam turbine, first to minimize the transient circuit, followed ensure turbine, condenser and low pressure cylinder blast films, auxiliary cooling pumps, water pumps, condensate pumps and other critical equipment to safely down, stressed that in the process, master control operator should concern the main aspects. This analysis of method is through on Unit II back road all important pneumatic mediation implementation institutions in lost instrument control with compression air of security state for analysis, first came single system lost instrument control with compression air of effect, then put important of Mediation system and important analysis of the loss of compressed air for instrument control together and concluded that overall run at full power state effect on unit and then find out proper ways.Finally on the current unit in compressed air for instrument control design deficiencies is to improve methods and operating procedures under such conditions.
