Critical Aspects

Flexible systems maintain a high performance level under changing operating conditions or design requirements. Flexible systems acquire this powerful feature by allowing critical aspects of their design con guration to change during the operating life of the product or system. In the design of such systems, designers are often required to make critical decisions regarding the exible and the non-exible aspects of the design con guration. We propose an optimization based methodology to design exible systems that allows a designer to effectively make such critical decisions. The proposed methodology judiciously generates candidate optimal design versions of the exible system. These design versions are evaluated using multiobjective techniques in terms of the level of exibility and the associated penalty. A highly exible system maintains optimal performance under changing operating conditions, but could result in increased cost and complexity of operation. The proposed methodology provides a systematic approach for incorporating designer preferences and selecting the most desirable design version — a feature absent in several recently proposed exible system design frameworks. The developments of this paper are demonstrated with the help of a exible three-bar-truss design example.

Stress And Strain Distribution

A steady-state thermo-hydraulic analysis of SB was done to get pressure drop and heat transfer coefficient in the cooling pipes, then a transient thermal analysis was performed to get temperature field of the SB with time in Inductive plasma operational scenario. Finally static structural analysis of the SB based on the temperature fields obtained with the transient analyses at specific time points were done to get the stress and strain distribution of the SB. The numerical analysis results were investigated by rules from ITER System Design Criteria for In-vessel Component to further verify the design. The final results of analyses indicate that the design of the SB meets with the ITER design requirements.

System Architecture Design

In order to design AP1000 protection system based on the FirmSys platform of CTEC, the AP1000 protection system based on CommonQ platform is analyzed and researched. Through the comparison of the FirmSys platform and the CommonQ platform, it is found that the number of cabinets should be increased largely if the protection system design based on the FirmSys platform refers to Westinghouse AP1000 protection system architecture. So that the cabinets can not be laid out in the electrical room due to the AP1000 electrical room space constraints. In order to solve this problem and to achieve the required reliability, the optimization of the emergency reactor trip and engineered safety features actuation control method based on FirmSys platform is studied. At last a new protection system architecture design is completed. It is proved that the optimized protection system architecture, in which the number of cabinets is reduced and the reliability is improved, not only can solve the cabinet layout problem, but also can meet the design requirements of AP1000.
