Review of advances in human reliability analysis of errors of commission, Part 1: EOC identification

In close connection with examples relevant to contemporary probabilistic safety assessment (PSA), a review of advances in human reliability analysis (HRA) of post-initiator errors of commission (EOCs), i.e. inappropriate actions under abnormal operating conditions, has been carried out. The review comprises both EOC identification (part 1) and quantification (part 2); part 1 is presented in this article. Emerging HRA methods addressing the problem of EOC identification are: A Technique for Human Event Analysis (ATHEANA), the EOC HRA method developed by Gesellschaft für Anlagen- und Reaktorsicherheit (GRS), the Misdiagnosis Tree Analysis (MDTA) method, and the Commission Errors Search and Assessment (CESA) method. Most of the EOCs referred to in predictive studies comprise the stop of running or the inhibition of anticipated functions; a few comprise the start of a function. The CESA search scheme—which proceeds from possible operator actions to the affected systems to scenarios and uses procedures and importance measures as key sources of input information—provides a formalized way for identifying relatively important scenarios with EOC opportunities. In the implementation however, attention should be paid regarding EOCs associated with familiar but non-procedural actions and EOCs leading to failures of manually initiated safety functions.     

An investigative study into the sensitivity of different partial discharge φ-q-n pattern resolution sizes on statistical neural network pattern classification

This paper investigates the sensitivity of statistical fingerprints to different phase resolution (PR) and amplitude bins (AB) sizes of partial discharge (PD) φ-q-n (phase-amplitude-number) patterns. In particular, this paper compares the capability of the ensemble neural network (ENN) and the single neural network (SNN) in recognizing and distinguishing different resolution sizes of φ-q-n discharge patterns. The training fingerprints for both the SNN and ENN comprise statistical fingerprints from different φ-q-n measurements. The result shows that there exists statistical distinction for different PR and AB sizes on some of the statistical fingerprints. Additionally, the ENN and SNN outputs change depending on training and testing with different PR and AB sizes. Furthermore, the ENN appears to be more sensitive in recognizing and discriminating the resolution changes when compared with the SNN. Finally, the results are assessed for practical implementation in the power industry and benefits to practitioners in the field are highlighted.     

Simple cost risk-benefit calculation: nuclear plant backfit analysis

The radiological risks include the probabilities and consequences of severe accidents at commercial nuclear power plants. The purpose of this paper is to present a valuation on the expected person-rem or societal committed dose from major accidents to identify whether back-fits in design modification can be supported. The approach of project evaluation by engineers of amortization is somewhat modified for these probabilistic events. A sample calculation is presented along with examples from published analytical calculations for several US light water reactors.     

Hyperconnected,receptive and do-it-yourself city. An investigation into the European “imaginary” of crowdsourcing for urban governance

This paper critically explores the construction and diffusion of the socio-technical imaginary of crowdsourcing for public governance in Europe via a quali-quantitative analysis of academic publications, research and innovation projects funded by the European Commission (EC) and local initiatives. Building upon the increasing narrative of digital social participation that describes crowdsourcing processes as short ways towards democratisation of public decision-making processes, our research describes the trends and threats associated with the “hyperconnected city” imaginary advanced by (part of) scholarly research and EC policy documents and projects. We show how, while these last describe digital-supported participation processes as (at least potentially) able to bootstrap an open governance agenda, local urban initiatives suggest the need to question this technology-optimistic imaginary. A critical analysis of crowdsourcing for public governance prototyped and piloted in some European cities makes it evident that at local level, alternative imaginaries are emerging. We describe them in this paper as the “receptive city” (often adopted by public institutions and administration), and the “do-it-yourself city” (referring to the critical perspective of (digital) social activists) imaginaries, both emerging from local-based experiences and debates; and clarify their convergence and divergence how these differs from the above-mentioned “hyperconnected city” imaginary prefigured by EC guidelines. The conclusive section further expands the analysis prefiguring future research possibilities promises in terms of local experiences influencing the future internet for society and digital agenda for Europe.

大型加氢精制装置的设计与运行

镇海炼油化工股份有限公司１．２ Ｍｔ／ａ加氢精制装置反应部分采用新型热高压分离流程,分馏部分采用双塔汽提流程,同时还设有循环氢、冷低压分离气和燃料气脱硫,以及溶剂再生设施,具有能耗低和产品质量好等优点。介绍了该装置的设计特点、标定情况以及生产中存在的问题。热高压分离与冷高压分离流程相比,其综合能耗约下降１２５．６ＭＪ／ｔ,但设备略有增加,故总投资也有所增加,而其总的经济效益也比较好。     

地质技术装备管理中的激励约束机制分析

搞好地质技术装备建设和管理是实现公益性地质调奁队伍精兵加现代化目标重要保障条件。本文从地质技术装备管理的目标出发，以激励和约束机制的理论分析为基础，对地质技术装备管理中激励和约束机制建立和实施进行了具体分析，提出建立系统的管理制度体系，完善管理组织结构和明确职责是实施地质技术装备有效管理的基本条件；地质技术装备管理的激励约束手段应以行政手段为主；建立地质技术装备管理考核制度，建立考核目标、量化指标、考核办法和奖惩措施，将地质技术装备管理水平纳入领导政缔考核内容之一。     

浅析国有企业如何落实“两个责任”

党的十八届三中全会《决定》提出院“落实党风廉政建设责任制,党委负主体责任,纪委负监督责任。”落实“两个责任”,是深入推进党风廉政建设和反腐败斗争的“牛鼻子”。作为国有企业,结合自身实际就如何抓好党委的主体责任和纪委的监督责任,以推动党风廉政建设和反腐败斗争深入开展。
