US NRC: Global nuclear energy revival expected

NRC Commissioner William C. Ostendorff speaks to Energy IQs Bryan Camoens on why international cooperation is valuable when it comes to nuclear energy. Commissioner Ostendorff also touches on the lack of skilled nuclear related workers and why massive growth of nuclear energy is expected.
Bryan Camoens:
What are some of the regulatory challenges and opportunities for expanding and new nuclear power programs?
Commissioner William C. Ostendorff:
The rising interest in new and expanding nuclear power programs presents many challenges and opportunities for the global nuclear community. A nuclear power program is a venture that can have a lifetime of up to 100 years or more. Therefore, a major challenge is the development of an effective and sustainable national infrastructure for nuclear safety and security. By infrastructure, I am referring to government and legal frameworks, organizational competence and technical capability of the operating entities, and associated human resource and development activities.
In this context, a key challenge is the establishment of an effective and independent regulatory body. In my view, regulatory effectiveness involves independence, clarity, reliability, efficiency, and openness in how the regulator conducts its business. With respect to regulatory independence, I believe that the regulator must be independent from the license holder and other entities so that it is free from undue pressure from interested parties.
I think the interest in new and expanding nuclear power programs provides a great opportunity to build upon and enhance international cooperation in the global nuclear community. Collectively, we have over fifty years of combined experience with commercial nuclear power. There are many insights and lessons learned to be shared in nuclear safety and security.
There are ongoing international efforts, bilateral and multilateral, aimed at supporting the safe and secure introduction and expansion of nuclear power. The U.S. Nuclear Regulatory Commission (USNRC) is a key player in many of these efforts. I believe that continued international cooperation is vital to ensure that plans for nuclear program development do not move faster than plans for establishing the necessary safety infrastructure and capacity.
Bryan Camoens:
How valuable is international cooperation when it comes to nuclear energy?
Commissioner William C. Ostendorff:
International cooperation, particularly for nuclear safety and security, is vitally important. The USNRC is an active participant in many international cooperative efforts in this regard. I take note of the significant nuclear reactor plant construction activity currently underway around the world, with about 60 reactors under construction in 15 countries. The rapid expansion of existing nuclear power programs and the wider use of radioactive sources and ionizing radiation throughout the world highlight the need for continued and improved international cooperation to address the associated challenges. The multinational nature of today’s nuclear industry underscores this need.
These activities are not limited to the borders of any one country. A nuclear activity in one country is more than likely to involve governments, non-governmental organizations, industry, and even the public in other countries. This multinational dimension creates complexities in supply chains and operational impacts that require good communication, effective cooperation, and appropriate oversight by regulators, vendors, and operators to ensure high levels of safety. I think it is well understood that a major nuclear power plant accident anywhere in the world would present a major challenge to the continued use of nuclear power throughout the world. We all benefit by international collaboration and sharing of lessons learned.
Bryan Camoens:
What is the rationale for looking towards nuclear as part of the power mix and is it an economically viable option?
Commissioner William C. Ostendorff:
As the regulator of the United States nuclear industry, the USNRC looks at whether a proposed nuclear power plant would meet our safety requirements for an operating license. While we examine whether an applicant has the resources to meet our requirements, a project’s overall economic viability (e.g., whether to proceed with a proposed nuclear plant or a natural gas facility) lies outside our safety requirements and is a decision for the utility licensee. The U.S. Department of Energy provides policy direction for the choice of power sources in the United States.
Bryan Camoens:
How is the global skills shortage going to impact including nuclear in the energy mix?
Commissioner William C. Ostendorff:
I think the need for technically competent and highly skilled nuclear workers is widely recognized, not only in the United States, but also throughout the world. The USNRC shares this need for skilled technical staff. In order to keep the nuclear education system healthy, the USNRC manages a multi-million dollar grant program to assist colleges and universities with nuclear-related education and training programs. We have seen encouraging signs of revival in nuclear engineering programs in the United States. I would expect that the supply of skilled nuclear workers will rise to meet projected demands in the future.
Bryan Camoens:
Chernobyl still haunts the public because of the devastation it caused, how can you overcome anti-nuclear sentiments - social, environment, corporate responsibilities?
Commissioner William C. Ostendorff:
This question pertains to an issue in which I have a keen interest – clear communications and effective outreach. As professionals in a highly technical field, we tend to be more comfortable communicating in our technical lexicon and jargon. However, that is not the best way to get our messages across to the public. I think the regulator and the nuclear industry have different but complementary responsibilities for effective communications and outreach with the public. As a regulator, our communications goal is to promote the understanding of risks associated with this technology and the bases for our regulatory actions. In doing so, the regulator needs to ensure that the public, who may not have a technical background, easily understands the messages in the context of other risks accepted every day.
I believe that it is also important for the public to have confidence in a strong regulator. A recent report from the OECD Nuclear Energy Agency (NEA) compared nuclear accident risks with those from other energy sources. What caught my attention was the impressive safety record of the nuclear industry compared to other energy sectors. A strong and independent regulator is a vitally important factor in laying the foundation for a continued strong safety record. The NEA report also showed a significant correlation between the trust in regulators and the belief that nuclear power plants can be operated safely, as well as a strong correlation between public trust of the nuclear industry and public trust in the regulator. This should be intuitively obvious. The collective focus by the industry and a strong regulator on safety, good communication, and meaningful outreach can help to build and maintain public confidence in the safe operation of nuclear facilities.
Bryan Camoens:
What are the current initiatives and the expected timeframe to integrate nuclear into the energy mix?
Commissioner William C. Ostendorff:
The USNRC has received 18 license applications for 28 new nuclear power plants; of these, 13 applications for 22 units are under active NRC review. We are also reviewing 3 new reactor design certification applications and 2 amendments to already approved design certifications. The USNRC’s current review timelines suggest that we will come to the first final decisions on the safety of new reactor designs and associated license applications in the near term. If the USNRC approves these licenses, some estimated project construction schedules call for approximately four to five years at least before they could begin operation. If all activities proceed to plan, the first of the new plants in the United States could be connected to the grid by the second half of this decade.
Another current initiative is with small modular reactors. While there are a number of technical and policy issues that require resolution, I can foresee small modular reactor designs making a contribution near the end of this decade if the technical and policy issues are adequately resolved and if the concept is environmentally viable.
Bryan Camoens:
What is the government’s role in driving nuclear energy policy forward?
Commissioner William C. Ostendorff:
The USNRC’s role is overseeing the safe and secure operation of existing nuclear power plants and ensuring that new nuclear power plants meet all the licensing requirements for safe and secure operation. This role requires a predictable and stable framework for regulation. The U.S. Department of Energy is responsible for shaping the energy policy and portfolio of the United States and the promotion of various energy sources, including nuclear power.
Bryan Camoens:
In your opinion is Nuclear a feasible option for the future of power generation or are there still safeties, technological and political issues that need to be addressed?
Commissioner William C. Ostendorff:
The USNRC has already certified several new reactor designs as being suitable for licensing in the United States and is currently examining several other new reactor designs. In general, the basic safety issues are addressed in these design certification reviews. The USNRC will continue to review new reactor license applications to ensure that the selected design is appropriate for a given site. It is my belief that continued engagement and education of the public can, in most cases, address any potential concern.
Bryan Camoens:
How will the nuclear sector evolve over the next decade?
Commissioner William C. Ostendorff:
One possibility I believe is that the nuclear energy sector may evolve from one that is based on large, light-water reactor designs to one that has greater variety of reactor sizes and coolant types. Regardless of how the industry evolves, I am confident that the USNRC will ensure that any evolutionary changes are safe and secure. I also believe that the projected demand for nuclear power generating capacity is a function of worldwide economic growth as well as associated policy decisions on matters such as objectives to reduce carbon emissions.
