The Korean Government has been implementing a nuclear phase-out policy since 2017. Nuclear power plants accounted for 30.0% of the total power generation in 2016; this figure fell to 25.9% at the end of 2019, and the average Capacity Factor (CF) of a nuclear power plant approximately dropped from 89.1% to 69.2%. The nuclear phase-out policy presents severe consequences for the sustainable management of the nuclear power industry. Accordingly, the purpose of this study is to analyze the effect of a decrease in the nuclear capacity factor under the nuclear phase-out policy on the depreciation cost per unit using the Straight-Line Method (SLM) and Decelerated Depreciation Method (DDM) and to provide recommendations from a sustainable management perspective. The results show that the decrease in CF of nuclear power plants has a negative impact on sustainable development of the nuclear power industry. DDM is more beneficial than the SLM during this initial stage of depreciation under the nuclear phase-out policy. In addition, in the early stages of projects or immediately after attracting large-scale investments, DDM can offer more positive signs for stockholders by calculating a smaller net loss or a higher net profit.

One of America’s best kept secrets is the success of its nuclear electric power industry. This paper presents data which support the construction and operating successes enjoyed by energy companies that operate nuclear power plants in the US. The result—the US nuclear industry is alive and well. Perhaps it’s time to start anew the building of nuclear power plants. Let’s take the wraps off the major successes achieved in the nuclear power industry. Over 20% of the electricity generated in the United States comes from nuclear power plants. An adequate, reliable supply of reasonably priced electric energy is not a consequence of an expanding economy and gross national product; it is an absolute necessity before such expansion can occur. It is hard to imagine any aspect of our business or personal lives not, in some way, dependent upon electricity. All over the world (in 34 countries) nuclear power is a low-cost, secure, safe, dependable, and environmentally friendly form of electric power generation. Nuclear plants in these countries are built in six to eight years using technology developed in the US, with good performance and safety records. This treatise addresses the success experienced by the US nuclear industry over the last 40 years, and makes the case that this reliable, cost-competitive source of electric power can help support the economic engine of the country and help prevent experiences like the recent crisis in California. Traditionally, the evaluation of electric power generation facility performance has focused on the ability of plants to produce at design capacity for high percentages of the time. Successful operation of nuclear facilities is determined by examining capacity or load factors. Load factor is the percentage of design generating capacity that a power plant actually produces over the course of a year’s operation. This paper makes the case that these operating performance indicators warrant renewed consideration of the nuclear option. Usage of electricity in the US now approaches total generating capacity. The Nuclear Regulatory Commission has pre-approved construction and operating licenses for several nuclear plant designs. State public service commissions are beginning to understand that dramatic reform is required. The economy is recovering and inflation is minimal. It’s time, once more, to turn to the safe, reliable, environmentally friendly nuclear power alternative.

During the late 1970s and early 1980s, the German nuclear power industry came under considerable socio-political pressure from the growing environmental and anti-nuclear movement. As part of a diversified public relations strategy, the Kraftwerk Union (KWU, later Siemens) as the main manufacturer of nuclear power plants distributed pre-printed QSL cards to amateur radio enthusiasts. These cards carried images of the latest nuclear power plants built by KWU. This paper examines the history, iconography and distribution of these QSL cards in the context of the heritage of the German nuclear power industry. It is the first study of its kind to examine the heritage significance of QSL cards.

Abstract China has the third largest fleet of nuclear power plants in the world, totalling more than 45 GWe at the end of 2019. With the current high rate of growth, its capacity will soon overtake that of France. The country’s nuclear power industry has suffered no serious accidents to date. Nevertheless, the poor safety record of some other heavy industries in China, combined with the rapid growth of civil nuclear power capacity, has raised concerns over the industry’s ability to prevent a serious accident. The organization, development and governance of China’s nuclear power industry reflects the high strategic importance that the government has placed on the industry over several decades. At the same time, it has taken steps to address domestic and international concerns over its ability to effectively govern nuclear safety and security. The country has become party to most major treaties and conventions relating to nuclear matters and has frequent interaction with the International Atomic Energy Agency. Despite many significant steps taken by the government, a number of questions remain concerning: the capacity and independence of the National Nuclear Safety Administration; the relatively incoherent nature of the body of laws, regulations and rules that govern nuclear safety and security; the absence of a clear legal basis for managing civil nuclear liability, especially in the context of an accident with transboundary consequences; and the quality of public participation, especially in the case of planned nuclear power plants.

In the nuclear power industry, there are various requirements for NDT laboratories depending on the type of work performed. The article reviews the following types of appraisal: 1) laboratory appraisal at the head materials science organization; 2) appraisal of NDT laboratories during the construction of nuclear power plants; 3) evaluation of the measurement condition in testing laboratories; accreditation of testing laboratories for product conformity assessment. The study concludes that presence of various requirements for NDT laboratories in the nuclear power industry introduces a certain ambiguity in obtaining the needed certificates

This article reviews that for the first time in a generation, utilities are starting the regulatory process to build nuclear reactors. There has been a virtual moratorium on new nuclear power plants in the United States during the past generation, and it has many causes. But one significant factor in the industry's decline was the Nuclear Regulatory Commission’s licensing process. There are now dozens of applications being submitted and approved for 20-year license renewals for established nuclear power plants. But before the nuclear power industry truly can be said to be reborn, new reactors must be constructed. The new rules allow for an early site permit and for a separate combined construction and operating license. Although the commission invited the nuclear power industry to test the two new processes when they were first announced, no company volunteered. One of the thorniest technical issues faced by the early applicants so far involves a new way of calculating, for a specific plant site, the ground motion that would result from a seismic event. When older plants were designed and built, the best available technique for these calculations was deterministic.

Risk-informed approaches (RIA) analysis in relation to nuclear power industry has been presented. Limitations of safety’s probabilistic analysis (SPA) as a main tool for RIA have been demonstrated. In particular, such SPA problems as statistics uncertainty related to equipment reliability and a problem of accidents modelling uncertainty using thermal-hydraulic codes have been analyzed. Recommendations for accounting of these uncertainties have been given. Ways of RIA further development and results of their application for substantiation and implementation of measures to improve the safety and operation efficiency of nuclear power plants have been presented. Results of the RIA application for such measures as equipment change-over to on-condition maintenance, reduction of amount of testing related to hermetic shell, measurement system accuracy evaluation, some systems’ modernisation feasibility study have been illustrated.

This paper briefly introduces the history, development, aims and roles, state of the art of Inspection Qualification in nuclear power industry in developed countries, such as US and UK. Then, the author reviewed the related works in China in past years and the state of art, the challenges and reflections of building China inspection qualification system. Furthermore, based on the actual situation in China, combined with the advantages and disadvantages of European Inspection Qualification system and ASME Performance Demonstration method, the author put forward some suggestions on organization, system and related technical basis to promote the establishment and development of inspection qualification system in China. It was obvious that the inspection qualifications have to be taken before nuclear power plant pre-service inspection or in-service inspection. The inspection qualification system shall be developed as soon as possible and it will improve nuclear power plants safety operation in China.
