For more than 60 years now, the nuclear power industry has relied on structural and pressure retaining materials generated via established manufacturing practices such as casting, plate rolling-and-welding, forging, drawing, and/or extrusion. During the past three years, EPRI has been leading the development and introduction of another established process, powder metallurgy and hot isostatic pressing (PM/HIP), for pressure retaining applications in the electric power industry. The research includes assessment of two primary alloys: 316L stainless steel and Grade 91 creep-strength enhanced ferritic steels, for introduction into the ASME Boiler and Pressure Vessel Code. Continuing DOE and EPRI research on other structural/pressure retaining alloys such as Alloy 690, SA 508 Class 1, Alloy 625, hard-facing materials, and others are also underway. This research will have a tremendous impact as we move forward over the next few decades on the selection of new alloys and components for advanced light water reactors and small modular reactors. Furthermore, fabrication of high alloy materials/components may require the use of new manufacturing processes to achieve acceptable properties for higher temperature applications such as those in Generation IV applications. Current research by EPRI and DOE will be reviewed and emphasis will be targeted at advanced applications where PM/HIP may be applied in the future.

The Relationship

Iran’s nuclear activities are prominent in today’s media reports. But few reports focus on the relationship between nuclear power and Iran’s energy needs. The Iranian government claims that nuclear technologies are vital for the national electric power industry and therefore for the country’s economy as a whole. It is common knowledge that the electric power industry is one of the main pillars of every country’s economy, directly influencing both state viability and national security. A state’s ability to provide and maintain the necessary amount of electricity production is vitally important. So, does Iran really, to such an extent, need nuclear power? My research shows that at the moment, and in the next ten years at least, the production of electricity using nuclear energy will secure an insignificant place in the energy basket of Iran.

Design Construction

Korea Electric Power Industry Code (KEPIC), a set of integrated standards applicable to the design, construction and operation of electric power facilities including nuclear power plants, has been developed on the basis of referring to the prevailing U.S. codes and standards which had been applied to the electric power facilities in Korea. Being the developing and managing organization of KEPIC, Korea Electric Association (KEA) published its first edition in 1995, the second in 2000 and the latest in 2005. KEPIC has been applied to the construction of nuclear power plants since 1997 in Korea. Along with the effectuation of the Agreement on Technical Barriers to Trade (TBT) in 1995, the international trend related to codes and standards is changing rapidly. KEA is, therefore, making its utmost efforts so as for KEPIC to keep abreast with the changing environment in international arena. KEA notified ISO/IEC Information Centre of its acceptance of the Code of Good Practice in the Agreement on TBT. Also the 2005 edition of KEPIC was published to be retrofitted according to the ISO/IEC Guide 21-Adoption of International Standards as regional or national standards. On the other hand, KEA is continuously performing to study on the improvement of KEPIC requirements. Such KEA’s efforts will help KEPIC correspond with international standards such as ISO/IEC standards, and internationally recognized standards such as ASME codes and standards. Furthermore KEA will expedite the publication of the bilingual edition of KEPIC at 2010 as per the globalization plan and KEA hopes that KEPIC can assist Korea Electric Power Corporation (KEPCO) and Korea Hydro & Nuclear Power Co., Ltd. (KHNP) in exportation of Korea Standard Nuclear Power Plant (KSNP) such as OPR-1000 and APR-1400 by the bilingual edition.

Technical Requirements

Korea Electric Power Industry Code (KEPIC) has been developed on the basis of referring to the prevailing U.S. codes and standards which had been applied to the electric power facilities in Korea. KEPIC has been applied to the construction of Ulchin Nuclear Units 5&6 since 1997 as per the endorsement of Ministry of Science and Technology, and is being completely applied to the construction of Shin-Kori and Shin-Wolsung Nuclear Power Plants (NPPs) in Korea and of Barakah NPPs in UAE. Although the technical requirements of KEPIC related to design and inspections for pressure vessels have been developed on the basis of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC), Korea Electric Association (KEA) that is KEPIC maintenance organization is trying to find and improve unreasonable requirements based on the acquired experiences for the continuous construction and operation of NPPs. In the administrative requirements, KEPIC, unlike ASME, adopted not only mechanical field but also electrical field related to NPPs. Furthermore, the qualifying system for services such as Nondestructive Examination, Heat Treatment, Design and Equipment Qualification Organization was adopted to improve safety and reliability for NPPs. In the technical and administrative requirements, KEA has been performing betterment studies such as ‘integration of welding coordinator in welding quality system of KEPIC’, ‘induction of Korean national standards (KS) materials equivalent to ASME/ASTM materials into KEPIC-MH codes’. The result of study for development of Steel-plate Concrete (SC) structure and modularization technique for NPPs has been adopted to 2010 edition of KEPIC-SNG.

Subject. This article deals with the issues relating to improving integrated reporting in terms of dovetailing strategic objectives with capital changes. Objectives. The article aims to develop a system of indicators for disclosure of capital types in integrated reporting of electricity generating companies, as well as recommendations aimed at implementing the fundamental concepts and guiding principles of integrated reporting. Methods. For the study, we used the methods of analysis and synthesis, comparison, generalization, and abstraction. As a case study, we conduct a comparative analysis of the disclosure of six types of capital by the largest electricity generating companies, namely PAO Inter RAO, AO Rosenergoatom and PAO RusHydro. Results. The article formulates proposals for disclosure of capital information to address such a lack of accountability as a contradiction to the principle of coherence. It proposes a system of indicators (core and additional) for disclosure of six types of capital by electricity generating companies. Conclusions. A significant reporting problem is the lack of correlation between key strategic objectives and capital changes. The formulated recommendations for disclosure of capital information can help solve this problem, and increase the attractiveness of the integrated report for capital providers.

The digital economy implies a structural transformation in many industries, including the energy sector, without taking into account the state specifics of the industry, for which full-fledged digitalization can be harmful. The aim of the study is to develop a methodology and determine the readiness of countries for digitalization in the electric power industry, taking into account all the main industry groups of factors. The paper analyzes the concept of “energy transition” and defines the indices that are applied to assess this transition at the global level. A system of indices is proposed to determine the degree of readiness for a digital transition in the electric power industry as one of the components of the “energy transition” and the most possible scenario for the transformation of this industry in Russia. The analysis of key areas of digital energy development is presented. The degree of readiness of the leading 100 countries in terms of GDP for digitalization in the electric power industry according to the proposed methodology has been calculated, and the further direction of basic research in this direction has been indicated. Conclusions have been drawn on the appropriateness of developing state programs and the main directions to which DM decision should be drawn with due desire to digitize the industry have been highlighted.
