The Logical Framework Approach (LFA) has proved to be a valuable tool for project approval, design, and evaluation. However, a few pitfalls make it hard to use within today's project management framework and to integrate with other project management tools. This article proposes an updated version of the LFA to improve its compatibility with today's corporate culture, project management framework, and tools. We propose to call the updated tool the Logical Framework Approach–Millennium (LFA‐M). The LFA‐M is a seven‐step approach leading to the development of the Logframe‐Millennium (LF‐M), a five‐column and four‐line matrix describing major project commitments and providing an overall understanding of the project. It was successfully implemented at the Canadian Space Agency and the Canadian Nuclear Safety Commission. The LFA‐M fits well within today's project management framework and corporate culture and leads easily to other project management tools.

This paper analyzes world steam generator (SG) operational experience (OPEX), research and development (R&D) for operational CANDU SGs. Emphasis is placed on design configuration, materials, and chemistry. SG OPEX from various databases is recounted to identify performance trends, active degradation mechanisms and common failure modes. A summary of CANDU and pressurized water reactor (PWR) SG OPEX including tube plugging statistics by material and degradation mechanism is provided. A discussion of ongoing SG-related research initiatives is also included. It was found that SGs with Monel-400 tubing and carbon steel tube support would perform well if properly maintained although Incoloy-800 tubing and stainless steel tube support is the current preferred design for CANDU, regarding Inconel-600 as an interim solution. All volatile treatment has also been adopted as the preferred SG chemistry for the CANDU fleet. Lessons learned from OPEX are highlighted and further international collaboration on the study of plant ageing, SG integrity, and nuclear safety is encouraged.
