  • Risk-informed inservice inspection (RISI) programs effectively concentrate limited and costly examination resources on systems and locations most relevant to plant safety. The thought process used in the selection of nondestructive evaluation (NDE) methods and procedures in a RISI program is expected to change toward integrating NDE into integrity management, with a concentration on understanding failure mechanisms. Identifying which damage mechanisms may be operative in specific locations and applying appropriate NDE methods to detect the presence of these damage mechanisms is fundamental to effective RISI application. Considerable information is already available on inspection for damage mechanisms such as intergranular stress corrosionmore » cracking (IGSCC), thermal fatigue, and erosion-corrosion. Similar procedures are under development for other damage mechanisms that may occur individually or in combination with other mechanisms. Guidance is provided on application of NDE procedures in an RISI framework to facilitate implementation by utility staff (Gosselin, 1996).« less
  • Process engineers and safety professionals have used qualitative and quantitative risk assessment techniques for many years to analyze process hazards. Environmental managers have recently been exposed to many of these techniques through submission of Accidental Release Risk Management Plans (40 CFR 68). This presentation discusses the broader application of such tools (Hazard and Operability Analysis, Fault-Tree, Failure Modes and Effects) to issues involving emergency and disaster preparedness and business contingency planning. In particular, the authors have successfully expanded the HazOp methodology to apply to a broad range of natural and man-made disasters that may affect continued business operations. Specific examples,more » including the development of comprehensive contingency planning for a water supply system, electronics manufacturer, and a distribution center will be discussed. These classical safety and reliability tools have broad application in the environmental planning arena, including emergency response and the operability of air and water pollution control equipment.« less
  • This paper describes the introduction of formal systems engineering including the introduction of a requirements management and modelling tool to a particular mass transit railway renewal project. The paper begins by explaining the nature of railway projects and the need, yet current scarcity, of application of formal systems engineering. It describes the specific project and the events leading up to the introduction of a systems engineering team into a project which would otherwise have not adopted formal systems engineering techniques. These are specifically the development of a code of practice and an initial feasibility study. It also describes the issuesmore » that have had to be resolved in this emerging application which include selection of a systems engineering tool, training, architecture and processes.« less
  • Screening level site specific human health and ecological risk assessments (ERA) were conducted at a historical (1908--1921) smelting and refining site in the Niagara Region, Ontario in accordance with the recently released provincial and federal risk assessment guidelines. The purpose of the assessment was to evaluate the risk associated with elevated levels of arsenic and lead in surface soils, and to assess alternative remediation options, prior to property transfer. Future intended land use will be parkland and for the site to remain forested. The identification of potential receptors, exposure pathways, and end-points was conducted at the biological community-level. The ERAmore » involved a toxic cue inventory of the core smelting and refining site, adjacent lands and a reference site. Development of remediation options was based on hazard assessment and the prediction of risks associated with arsenic contamination. An evaluation of remediation options and the selection of a preferred option are discussed.« less
