Research on Severe Accident Mitigation Strategy of Injecting Into the OTSG of ACP100

Zhiqiang Zou Ming Zhang Chunrui Deng Deng Jian Qingan Xiang

The China multipurpose module small reactor named ACP100 is developed by the China National Nuclear Corporation (CNNC). The severe accident management guidelines (SAMGs) of ACP100 reactor is necessary to be developed to mitigate the severe accident induced by in the multi-cause extreme conditions. Inject into the steam generators (SGs) is one of the most significant strategies, this strategy aims at protecting the SGs tubes from creep rupture, removing the heat from the reactor coolant system (RCS) and depressurizing the RCS. The entry condition of the severe accident guideline of injecting into the SGs, as usual, is low SG Water level in the most of the present pressurized water reactors that adopt the inverted U-tubes SGs. The integral reactor of ACP100 adopts the design of annular tube once-through SGs. In the normal conditions, the secondary side of the OTSGs is operating in a given steady pressure, any water level measure tool is impossibly set in the OTSGs. Therefore, on the basis of the design features of ACP100, the strategy of injecting into the OTSG at severe accident is studied, the potential entry condition of the corresponding guideline is discussed. And the validity and feasibility of the strategy is validated by the analysis of the integral systems analysis code.

Effect of Transient Conditions on Combustion Noise of Internal Combustion Engines

Neiranji gongcheng (2006)

Zhiyi Yang

This article studied the effect of transient conditions on combustion noise of DIDiesel engines.By developing testing technique and method of transient conditions and studying the difference of cylinder pressure,maximal cylinder pressure,rate of pressure rise,maximal rate of pressure rise,highfrequency oscillation of combustion pressure and cylinder pressure level in different frequency between transient conditions and steady conditions,the mechanism of difference between transient conditions and steady conditions was analyzed from the point of aerodynamic load and highfrequency oscillation of combustion pressure.The changing trend of rate of pressure rise was similar to the combustion noise,but there were differences existing in some conditions.It was the result of effect of the highfrequency oscillation of combustion pressure on combustion noise.The result shows that the aerodynamic load and highfrequency oscillation of combustion pressure working together result in difference of combustion noise in transient conditions compared with steady conditions in the same load and at the same rotation speed.

Secondary Influence Factors of Combustion Noise Mechanism under Transient Conditions of DI-Diesel Engine

SAE technical papers on CD-ROM/SAE technical paper series (2006)

Gequn Shu Haiqiao Wei Yangjun Wang Wei Jingsi Zhiyi Yang

The secondary influencing factors of combustion noise mechanism under transient conditions of DI Diesel engines were studied.The secondary influencing factors of combustion noise were measured under steady and transient conditions.Under the same load and engine speed,the secondary influencing factors of combustion noise was analyzed including combustion chamber wall's temperature,fuel injection pressure,needle lift between transient conditions and steady conditions.The difference of the secondary influencing factors under the two conditions affects the aerodynamic load,high-frequency oscillation and combustion noise between steady and transient conditions.The secondary influencing mechanism of combustion under transient conditions at different fuel delivery advance angles is also studied.The result shows that wall temperature of combustion chamber,fuel injection pressure,maximum of needle lift and opening duration of needle lift under transient conditions are higher than those under steady conditions in the same load and engine speed,resulting in the difference in ignition delay,starting point of combustion,and fuel injection quantity between transient and steady condition,influencing the aerodynamic load and high-frequency oscillation of combustion pressure,making the difference of combustion noise between the two conditions.
