A travelling wave reactor (TWR) is an advanced nuclear reactor which is capable of running for decades given only depleted uranium fuel, it is considered one of the most promising solutions for nonproliferation. A preliminary core design was proposed in this paper. The calculation was performed by Monte Carlo method. The burning mechanism of the reactor core design was studied. Optimization on the ignition zone was performed to reduce the amount of enriched uranium initially deployed. The results showed that the preliminary core design was feasible. The optimization analysis showed that the amount of enriched uranium could be reduced under rational design.

Head Protection

Head impact with bonnet is one of the major causes for pedestrian severe injury or fatality in car accidents. This paper proposes a multidisciplinary design optimization method for bonnet inner based on pedestrian head protection along with bonnet stiffness requirement. A finite element (FE) model of a child headform impactor is developed and verified via simulation according to Global Technical Regulation No. 9 (GTR No. 9). Static stiffness analysis and headform collision simulation against one impact point for a particular bonnet are implemented. Parametric design and optimization analysis are carried out. Optimization solution significantly achieves a better head protection effect, which clearly affirms the feasibility of the proposed multidisciplinary optimization method and provides a reference approach to optimal design of engine bonnet inner.

Subcritical System

In China Lead Alloy Cooled Research Reactor (CLEAR-I), which is an accelerator driven subcritical system, a proton tube inserts into core from the top of reactor. Some neutrons will leak out along the proton tube, inducing structure materials damage and potential exposure danger for workers. The shielding design and optimization analysis for the proton tube of CLEAR-I was conducted using the VisualBUS system developed by FDS Team in this study. The result indicated that during operation allowed working time at outside containing compartment above the reactor shall not exceed 40 hours per week and entering into containing compartment was forbidden. Above results showed that the design after optimization basically met the requirements of shielding.
