HRA in a NPP;quantity analysis;time division and parameter determination
摘要：
The purpose of human reliability analysis (HRA) is to provide a quantitative conclusion for Probabilistic Safety Assessment (PSA) and detect the weak points of a system. The failure probability of post-accident human factor events is composed of cognitive failure probability PI, non-response probability P2 and the failure probability P3 of conducting the critical actions according to EOPs. The paper adopts the method of combining THERP and HCR and quantifies P1, P2 and P3 separately. In the analysis procedure the particular time division and parameter selection principle are put forward and illustrated by examples.

摘要：
Based on human' inherent characteristic, the state of network information security, etc, it is necessary to form the human errors analysis theory for network information security. The theory can be established, because it has possessed three conditions: theoretical basis, technological support and practical environment. This paper discusses the three conditions. The final goals of the human errors analysis theory for network information security reduce and prevent human error and strengthen human's management in network. The theory conduct an investigation into ordinary behavior rule of human errors in network, the quantitative and qualitative evaluation for human factors and human errors and its process, and the measure preventing and reducing human error.
摘要：
The structure characteristics and running conditions of the uranium mill-tailing site in southern China were investigated. Based on the geological and hydrogeological analysis of the study site, the ID-coupled solute reaction-transport numerical model was set up to simulate the representative radionuclide-uranium(U6+) migrating in shallow groundwater at the uranium mill-tailing site using the recently updated PHREEQC version 2 code. The effects of the uncertainty factors in the aqueous-complexation, adsorption-desorption, ion exchange, surface-complexation, dissolution-precipitation, and redox processes were considered in the numerical model. Furthermore, the cases of the U6+ migrating in the groundwater in different conditions were discussed at the study site. The results showed that PHREEQC version 2 successfully simulated the U6+ migrating in the shallow groundwater. The simulating results were accordance with the observation records in site and the feasibility of the model was proved. It also could be obtained that the effect of the dispersion was remarkable but the molecule diffusion could be ignored in this model. Selecting the values of the dispersion coefficient was a key factor in this modeling. It could also provide valuable reference for the risk assessment and treatment after the decommission of the uranium mill-tailing site. Furthermore, the results could demonstrate that treatment engineering was necessary after its decommission.
摘要：
The strength and ductility are the most important seismic indexes for the high strength concrete (HSC) frame columns, respectively. Firstly, in the paper, the seismic strength and ductility of these kinds of columns, which used C60 and C90 concrete and 1420 MPa yield strength rebars, were developed systematically by 6 model tests under the low circle repeated loads in the lab. Secondly, some non-linear numerical analyses also were carried out for columns with the same parameters. Finally, an experiential formula for the ductility, which is related to both the axial compression ratio and the index of stirrup, was derived on the basic of test data and numerical analysis results. The results of both test and analysis show that the strength and ductility were related closely to the following parameters: the axial load ratio, the index and spacing of stirrups, and type and strength of the confinement and longitudinal rebars etc. The flexural behaviors of the columns can be effectively improved by mixed ultra high and normal strength steel bars for the longitudinal reinforcement, especially in the case of high axial load levels. Moreover. the results were also shown that the ductility of HSC Columns, which were reinforced by ultra strength stirrup rebar, was better than the one by the normal reinforcement because the high strength rebar can provide the good confinement forces for the core concrete.

ABSTRACT: Deep ocean cobalt crust is about 5cm thick and as hard as coal. For mining the crust, a drum cutter similar to that for mining coal was conceived. A cutting model was proposed to describe the cutting process of a single tooth, the forces on the tooth were analyzed and the cutting force was calculated. The model and the analysis will be of great help to the design of the drum cutter upon taking into account the associated engineering issues and equipment design in operating 800−3000 m depth in the ocean. INTRODUCTION As we know, there are much more mineral resources on the sea floor than on the land (Manheim, 1986; Manheim, 1988). Since the mineral resources on the land are being used out, mankind has to turn to the ocean and exploit the mineral resources on the sea floor. Currently, many countries are competing to exploit the mineral resources on the sea floor. China has taken thirty years of great efforts to have an area in international seawaters. In this area, there are enormous amounts of cobalt crust. The curst is variable in its thickness, ranging from 1cm to 15cm, mostly from 4cm to 6cm. Its color is black red, its surface, in the shape of smooth grape, sometimes, flat and smooth. The crust is directly contacted with undersea hill side slope rock, with no sediments between them. The seabed rock is generally alkaline basalt, degenerative basalt or glass fragmentary rock (Bu and Qiu, 2002). The density of the crust is between 1.6g/cm3 and 2.17g/cm3, its compressive strength, between 0.5MPa and 16.8 MPa (Yamazaki and Sharma, 1998; Yamazaki and Sharma, 2000). As far as the strengths are concerned, the crust is equivalent to the coal and can be considered to be a kind of soft rock.
