Welcome to the “Nuclear Renaissance”... The global nuclear renaissance and concerns over climate change were addressed by the keynote speakers at the 20th anniversary of POWER-GEN International, December 2, 2008. J.M. Bernhardt, Jr., chairman, president and CEO of Shaw Group, opened his presentation by acknowledging that the nuclear renaissance is not something that might happen; it is happening now. He stated that “When greenhouse gasses are in the mix, he believed nuclear is where we need to go.” Additionally, Jacques Besnainou, president and CEO of Areva, Inc supported Bernhardt with the call for more investment in nuclear power. He stated that “nuclear power is not THE solution, but there is no solution without nuclear power. What Will it Take to Make the Global Nuclear Renaissance a Success?Must have the need... The Department of Energy (DOE) indicates U.S. energy consumption is expected to grow 1.5 percent a year over the next two decades, and should reach an increased 45% baseload need by 2030. Additionally, the gap between total worldwide energy production and demand will double over the next 15–20 years. Must have the will... Nuclear Energy Institute (NEI), and World Nuclear Association indicate that globally, 36 plants are currently under construction, 93 plants are on order or planned in 18 countries (30 in U.S.), and 219 projects are under consideration in 27 countries. Additionally, they indicate that the combination of low production costs, high reliability, safe operation and clean air benefits positions nuclear energy favorably to meet our baseload electricity needs today and for future expansion. Must have the commitment... Each of us who are members of the global nuclear community must have our core values embedded in a solid quality foundation. We exercise our commitment to quality daily by the application of our signature on documents, instructions, and drawings.

Human Beings

Nuclear energy is bound to have a negative impact on the survival of human beings. Although scientists hoped to end all wars, the nuclear arms race resulted in huge amounts of warhead reserves throughout the globe. When we consider the effects of radiation exposure, a hostile attitude is common worldwide, mostly because there is no threshold in radiation exposure, and even a small degree of exposure would cause diseases. This attitude also resulted from the explosion of the atomic bomb, killing many people. The general public became worried about radiation exposure, which led to many lawsuits worldwide. In the United States of America, the Atomic Energy Commission (AEC) at that time, reorganized as the Department of Energy (DOE) later, encountered a problem when a military plane carrying hydrogen bombs met an accident and crashed in Spain, resulting in contamination of the immediate area. The AEC had a policy in principle that countermeasures against radiation exposure should be as limited as possible. The management of man-made radiation varies from one country to another. Countries like the USA try to find rational and universal applications for human activities, while countries like Japan try to keep utilitarianism even after the Fukushima accident. In this paper, the history of the atomic bomb deployment will be reviewed again in light of its influence on the general public, especially in the context of radiation exposure. The world is gradually shifting in accepting nuclear energy as a part of Sustainable Development Goals' (SDGs) climate change solutions. However, radioactive waste is still a significant hurdle in transitioning from fossil fuel to nuclear energy. This study will analyze past events and determine how to proceed with the radiactive waste argument to obtain the general public's reasonable understanding and acceptance.

Uranium From Seawater

There has been historical interest in harvesting uranium from seawater for nuclear energy over the past few decades, with the goal of lower extraction cost to become competitive with land-based uranium. This review provides a brief background on the extraction of uranium from seawater and on recent work from groups supported by the United States Department of Energy on this project.

Performance Demonstration

This paper evaluates non-destructive examination (NDE) detection capabilities for fatigue cracks in piping. Industry performance demonstration initiative (PDI) data for fatigue crack detection were used to develop a matrix of statistically based probability of detection (POD) curves that consider various NDE performance factors. Seven primary performance factors were identified — Material, Crack Geometry/Type, NDE Examination Access, NDE Procedure, Examiner Qualification, Pipe Diameter, and Pipe Wall Thickness. A database of 16,181 NDE performance observations, with 18 fields associated with each observation, was created and used to develop statistically based POD curves for 42 stainless steel and 14 carbon steel performance cases. Subsequent comparisons of the POD fits for each of the cases showed that excellent NDE performance for fatigue cracks can be expected for ferritic materials. Very little difference was observed between the POD curves for the 14 carbon steel performance cases considered in this study and NDE performance could therefore be represented by a single POD curve. For stainless steel, very good performance can also be expected for circumferential cracks located on the same side of the weld from which the NDE examination is made. POD depended primarily on component thickness. Three POD curves for stainless steel were prepared. Best estimate and the associated 95% confidence bounds for POD versus through-wall depth logistic regression digital data are provided. Probabilistic fracture mechanics (PFM) calculations were performed to compare best estimate leak probabilities obtained from both the new performance-based POD curves and previous PFM models. This work was performed under joint funding by EPRI and the U.S. Department of Energy (DOE), Office of Nuclear Energy Science and Technology’s Nuclear Energy Plant Optimization (NEPO) program.
