On the one hand customs authorities are charged with the responsibility for policing a country＇s borders, and consequently they need to have in place measures to ensure that only legitimate trade takes place and that this trade does not present security concerns. On the other hand we have the requirements of traders, who benefit from an environment of trade facilitation with speedy and efficient movement of cargo across international borders, with minimal bureaucratic intervention. This paper focuses on and provides early discussion and comments on the possible ramifications of the introduction of the 24-hour rule in China, effective for all exports and imports of sea freight container traffic since January 1, 2009. The new rules will have significant impact on the logistics flows of exporters and importers alike. Specifically, the reporting requirements timelines are likely to result in increased costs in cargo processing at wharves that traders will have to bear; place added pressure on storage facilities at wharves, or at container depots; and may additionally increase the amount of inventory buffer because of the timing of the data reporting requirements. The paper concludes that security needs have prevailed over trade facilitation considerations and that traders should urgently implement a review of existing practices to ensure they comply with the China Customs requirements, whilst simultaneously minimizing cost increases.展开更多

The MI of HSIs in the MCR indicates the HSIs that the operator always needs available to： （1） monitor the status; （2） perform and confirm a reactor trip; （3） perform and confirm a controlled shutdown of the reactor; （4） actuate safety related systems; （5） analyze failure conditions of the normal HSIs; （6） implement the plant＇s emergency operating procedures （EOPs）; （7） bring the plant to a safe condition; （8） carry out those operator actions shown to be risk important by the probabilistic risk assessment （PRA）. The proposed analytic procedure on the MI of HSIs in this study can be used to （1） identify the MI of HSIs and their design requirements; and （2） address design requirements and implementation for the MI of HSIs. The contribution of this study is to describe the MI of HSIs needed to implement the plant＇s EOPs, to bring the plant to a safe condition, and to carry out those operator actions shown to be risk important by the PKA.展开更多
