An easy method to design gas/vapor relief system with rupture disk

Tank discharge gas/vapor flow problems are frequently encountered in both practice and design. To perform this type of design calculation, the first step is to identify whether the flow is choked or not through a trial-and-error solution of an equation for adiabatic flow with friction from a reservoir through a pipe. Developing a direct method without any trial-and-error to identify a choking condition would be helpful for expediting the flow calculations. This paper presents an easy and quick method to identify the choking of gas flow for an emergency relief system consisting of a rupture disk and vent piping. This greatly simplifies the design calculations. The proposed method for validating the venting adequacy of existing ERS circumvents the iteration calculation and the use of Lapple charts. Three case studies for the design of vent piping for rupture disks support the proposed method.     

Earthquake Planning for Government Continuity

/ The problem of assuring government operational continuity following earthquakes has been given little research attention. Recent earthquake experience has documented that government organizations without a public safety mission do incur damaged facilities and routinely see increases in public demands following an earthquake. Impediments to service delivery associated with such dam-ages can be minimized if agencies address earthquake plan elements likely to enhance postimpact functioning, including: the potential to relocate operations, protection for the workplace, possession of an organizational inventory, emergency instructions for employees, the ability to use volunteers, and communication capacity. Factors associated with the adoption of these plan elements were studied in one county government and its municipal county seat in the southwestern United States. A census of departments within these jurisdictions was asked to complete a questionnaire reporting the level of planning activity relative to each of these plan elements. It was found that the overall level of preparedness was low, but statistically significantly related to agency size, perceived risk, and information seeking. The implications of these findings underscore the potential for disruption to government service delivery and permit the identification of potential avenues for increasing levels of preparedness.KEY WORDS: Emergency planning; Earthquakes; Government preparedness

A taxonomy of performance influencing factors for human reliability analysis of emergency tasks

This paper introduces the process for, and the result of, the selection of performance influencing factors (PIFs) for the use in human reliability analysis (HRA) of emergency tasks in nuclear power plants. The approach taken in this study largely consists of three steps. First, a full-set PIF system is constructed from the collection and review of existing PIF taxonomies. Secondly, PIF candidates are selected from the full-set PIF system, considering the major characteristics of emergency situations and the basic criteria of PIF for use in HRA. Finally, a set of PIFs is established by structuring representative PIFs and their detailed subitems from the candidates. As a result, a set of PIFs comprised of the 11 representative PIFs and 39 subitems was developed.     

Survey-based analysis of evacuation preparation behaviors in a chemical leakage accident: A case study

Public evacuation preparation exerts an important impact on overall evacuation efficiency during regional evacuations. Early warnings often delay the occurrence of chemical accidents. Studying the characteristics of public evacuation preparation in such accidents will help develop better evacuation strategies considering the actual public response. In this work, the characteristics and factors influencing public evacuation preparation behaviors were analyzed by examining an evacuation case in China. The results indicated that the probability distribution of public's evacuation preparation time during a regional evacuation conforms to a Weibull distribution regardless of whether or not evacuation warnings were received. An estimation model of the traffic flow loading rate in a regional evacuation was then proposed on the basis of this finding. The results of this research can provide a reliable reference for evacuation modeling or logistics optimization for future incidents.
