Expert system approach for reactor vessel integrity

This paper describes the development strategy of a prototype expert system, called RViES, for the reactor vessel integrity. The main objectives of the system are to assist engineers to perform fatigue and fracture mechanics analyses of reactor vessels quickly and accurately. The system consists of three parts; user interface, knowledge base and inference engine. Various rules recommended in codes and standards are stored in the knowledge base. Several case studies were performed to check the usefulness of the system.

Modeling of protein adsorption to DEAE sepharose FF: Comparison of data with model simulation

The equilibrium and kinetic characteristics of the adsorption of human serum albumin (HSA) and ovalbumin (OVA) to the DEAE Sepharose FF weak anion exchanger were experimentally determined. The rate for protein adsorption was simulated with two different models, the first being based on a single lumped kinetic parameter, while the second includes the individual mass transfer processes occurring prior to the adsorption intervention, i.e., diffusion across the liquid film surrounding individual particles and diffusion within the ion exchanger particle itself. The actual adsorption of OVA to DEAE Sepharose FF in fully mixed stirred vessels and in packed bed columns was consistent with both models. In the case of HSA, however, the adsorption profile in an agitated vessel was consistent only with the pore diffusion model and neither model could correctly predict the latter part of the breakthrough profile observed in packed bed experiments.

基于Sesam仿真的原油转驳船主机基座强度校核

为保证主机基座满足原油转驳船(Crude Transfer Vessel, CTV)正常工作时的强度要求,建立CTV主机基座的三维仿真模型。采用Sesam软件在多种载荷施加状态下对主机基座的应力分布和自振性进行分析和校核。结果表明,主机基座区域应力最大值为237 MPa,低于最大许用应力284 MPa。当主机正常工作时,基座各节点振动位移不超过3 mm,且固有频率处于危险共振频率区间外,不会产生有害振动。主机基座结构强度符合CTV船体技术要求。
