Koeberg NPP path to demonstrate safe LTO – synergies of SALTO and PSR activities

Koeberg NPP has been preparing to enter LTO once the Regulator approves the LTO license application. The purpose of my presentation is to provide industry operating experience (OPEX) on the use of PSR, SALTO ageing management approach and SALTO peer review to support preparation for LTO. The OPEX will consider the integration of PSR and SALTO, the use of the outcomes of these assessments to develop the safety case for LTO.  The presentation will also share the approach taken in documenting the justification for continued operation and the safety case for LTO. In closure, the presentation will conclude on lessons learnt during the preparation period.

Koeberg NPP considers that the information to be shared will add value to the nuclear industry on the use of the safety and ageing management assessments to support LTO. Koeberg NPP worked with international peers and nuclear agencies to ensure adequate preparation and there are a lot of lessons learnt to be share. 

Ageing management from commissioning to subsequent LTO periods

The presentation addresses some of the aspects related to managing the ageing of structures, systems and components (SSCs) from the initial commissioning phase through subsequent long-term operation (LTO) periods. Effective ageing management of SSCs requires the use of a systematic approach to managing the effects of ageing to ensure that SSCs are able to accomplish their required safety functions throughout the lifetime of the nuclear power plant (NPP).

Subsequent License Renewal – U.S. fleet perspectives, regulatory and industry challenges

The U.S. fleet includes 54 reactors that are operating beyond 40 years of service – the longest at 54 years, and there is high interest by the industry to continue to 80 years. Learning from operating experience and proactively addressing technical challenges is essential to achieving that aim. This presentation will share the U.S. NRC’s early experiences in issuing subsequent renewed licenses (60-80 years), highlighting some of the plant-specific and industry-wide technical issues associated with aging plants. Topics will include both current operating issues, including occurrences of failures of buried fire protection piping, and concerns that will gain greater significance later in plant life, such as maintaining fracture toughness margins for the reactor pressure vessel. To support effective management of such issues, the NRC continues to enhance its technical guidance and regulatory oversight processes. Engagement with the international community in forums like the Nuclear Innovation Conference helps to ensure the NRC’s LTO approach is well-informed of global experiences and best practices.

Digital Twins for Improving Accuracy of Thermal Fatigue and Environmental Qualification Time Limited Aging Analyses

Time-Limited Aging Analyses (TLAAs) is a term directly associated with the Long-Term Operation of Nuclear Power Plants. The revalidation of TLAAs is a necessary task to undertake before the plant enters its extended operational period beyond its original design life. In this regard, the international regulatory framework suggests reducing the conservatism applied in the original design calculations as an accepted method to demonstrate whether components within the scope of TLAAs are capable of performing their Safety Functions during the extended period of operation. The current state of technology provides us with an opportunity to achieve this through the improvement of accuracy compared to the original calculations.

EPRI Technical Support for Nuclear Plant Operation to 60 Years, 80 Years, or More

EPRI’s efforts to study the option of long-term operation (LTO) or operation beyond the original license period have been underway for decades.  EPRI worked with the U.S. nuclear industry in the 1980’s and 1990’s to research the options and challenges for operation beyond 40 years, which was the original license period for U.S. nuclear power plants.  After extensive studies, both technical and economic, EPRI was able to provide needed technical support for the first license renewal applicants in the late 1990’s.  Due in large part to the success of those first license renewal projects, more than 90% of the 93 nuclear plants currently operating in the U.S. have received regulatory approval to operate for up to 60 years [1] and most of the remaining plants have applications under review or have announced plans to submit applications. 

Topical workshop on effectiveness of ageing management programmes (AMPs) and plant level AMP

NRG hosted the first Nuclear Innovation Conference (NIC) in Amsterdam on 8-9 June 2022 with objective to discuss the promises, risks and common challenges of existing and future nuclear energy communities and to facilitate further cross-disciplinary collaborations and experience exchange. This two day event for the nuclear industry and regulatory authorities had a general plenary session on day 1, followed by three parallel sessions on Long Term Operation (LTO), New Build and Advanced Reactors on day 2.

It was a successful event with more than 200 participants from 70 organization and 20 countries. Feedback from participants was very positive, therefore NRG has decided to organize NIC regularly with periodicity of two years. Second edition, NIC2024 will be organized on 5-6 June 2024.

NIC2022 participants discussed and shared their challenges and needs for further development. In the LTO area, covering also ageing management activities, exchange of experience and enhancement of activities to monitor the effectiveness of ageing management programmes (AMPs) and plant level AMP was identified as one of the main outcomes of LTO session. Therefore the NRG has organized a webinar  ‘NIC topical webinar on effectiveness of AMPs and plant level AMP’ on 8 November 2022.

Based on a very positive feedback, NRG has decided to organize a fully in-person ‘NIC topical workshop on effectiveness of AMPs and plant level AMP’ at NRG facilities in Petten, the Netherlands on 18-19 January 2023.

Nuclear Innovation Conference 2024: June 5-6

We've set the date for the second edition of the Nuclear Innovation Conference. We hope to see you at June 5-6 for another energizing conference where we can meet, collaborate and share knowledge on nuclear energy. Pre-registration starts soon!

Nuclear Innovation Conference 2022: final remarks!

The Nuclear Innovation Conference 2022 has ended! We look back at two amazing days.

Vendors, utilities, regulators and other stakeholders were brought together at the NIC. Some important conclusions were shared: there is a large ambition to fill the gap between supply and the projected demand given the energy transition and the delivery from Wind, Solar and Nuclear energy. Technologies are available and new concepts are developing fast but collaboration is needed, characterized by coopertition: collaboration in a competitive environment. The goal of the conference was alignment on accelerating nuclear innovations in Long Term Operation, New Build and Advanced reactor development. 

Formulating key success criteria for acceleration:
• Speedup decision making in LTO programs;
• Think big for New Build in large numbers and series, including repurposing of coal plants;
• Develop a common framework of requirements for standardization at European and Global level;
• Develop customer oriented products; besides electricity, include heat/hydrogen demand for further decarbonization;
• Develop the collaboration environment between owner, supplier and regulator;
• Continue working on waste solutions for public acceptance.

We are looking forward to organizing the second edition in 2024!

LTO enhancements at NPP Krsko

NEK as a Westinghouse designed plant has primarily followed the requirements and guidelines issued by the U.S. NRC. This is especially relevant to the Ageing management component of Long Term Operation. During that development of the Plant Ageing Management Program, general methodologies were prepared, using 10 CFR part 54 and the GALL Report of NUREG-1801 as the most important references. Before entering the LTO period a substantial Safety Upgrade Program has been performed, which includes Dry storage of Spent fuel, new bunkered Emergency control room, a Bunkered building with two 1500 m3 water storage tanks and a third safety train to remove decay heat through the primary or secondary side, PARs and filtered venting which can operate in design extended conditions. Additionally NEK has aligned its processes to the International practices and standards such as those of the IAEA (the International Atomic Energy Agency) and WENRA. With the preparation for LTO certain organizational changes for Ageing management, additional LTO and AM trainings and process updates have been performed, to more effectively support LTO.

Rigid and reliable design, which is better understood through the operational practice and experience of today, and stable and reliable operation that follows national and international practices – is an essential basis for continuing operation of plant beyond the initially established time frame.

LTO of NPP Oskarshamn 3

Oskarshamn unit 3 is the only NPP in Oskarshamn which remains in operation. Unit 1 and 2 is currently being decommissioned. Unit 3 was put into operation in 1985 and is intended to be in operation until 2045 with the option of running all the way to 2065. The LTO project has the mission to update the current ageing management programme to be in line with IAEA Safety Guide SSG-48.

Currently, they are in the middle of updating the scope for ageing management. Alongside the scoping group they have made the commodity group methodology (called Ageing Group Methodology in their case) and AMR methodology with support of workshops and discussions with NRG. Time Limited Ageing Analyses have been updated. Pilot ageing management review reports for systems containing both mechanical and electrical/I&C SSCs are in preparation and will be submitted for review by the IAEA Pre-SALTO mission which will start at the end of August 2022.

The full event-experience at NEMO Science Museum

We are hosting the Nuclear Innovation Conference (NIC) 2022 at the NEMO Science Museum in Amsterdam. The building is a striking, copper-green shape rising high above Amsterdam’s eastern docklands. The impressive futuristic building, designed by the Italian architect Renzo Piano and located in the center of Amsterdam, also offers access to the highest Rooftop Square in the Netherlands.

NEMO’s mission is to bring science and technology closer to the public in an interactive and accessible way, in the museum, at schools, at nationwide events and online. At NEMO, everyone – from young to old – discovers how fascinating science and technology are. On five floors crammed full of exhibitions, experiments, demonstrations and workshops, visitors discover how special everyday things are.

We are thrilled that we host our first NIC at this location. The combination of technology, science, architecture and location is one that will enhance the event-experience.

Evolution of EDF ageing management in the frame of LTO

The EDF ageing management process has been deeply upgraded in the objective to extend the lifetime of the French nuclear fleet. The various documents that synthesize this process have been completed with the aim of integrating lessons learned from the different benchmarkings led by EDF. These benchmarks were performed with international standards and guides, and with other utilities to evaluate the completeness and the conformity of the EDF ageing management process. Particular attention has been paid to the extension of the scope of ageing management, the description of the means of mitigation of ageing mechanisms, the identification of acceptance criteria for each couple SSC/ageing mechanism and of study notes equivalent to Time Limited Ageing Analyses. The LTO program is supported by a large R&D support program based on ageing mechanism knowledge improvement such as material ageing studies in the frame of mechanical components and the expertise of a steam generator withdrawn from service.


Rescheduling of Nuclear Innovation Conference to 8-9June 2022

We are rescheduling the Nuclear Innovation Conference, that was planned for 24-25 March 2022. The main reason is that with the ongoing COVID-19 situation, we cannot ensure a healthy and full experience that we intend to offer during this conference. That's why we've decided to host the NIC at 8-9 June 2022. Same location, the same program and the full experience!

If you haven't registered yet, registration for June is open right now! If you already signed up, your registration is automatically transferred to June. Please send us an e-mail if you have any questions about registration. 

Even though we are disappointed to reschedule the event, we also see opportunities to improve the program and ensure that we can provide you the ultimate nuclear networking event in 2022!

Nuclear Energy part of new Dutch Coalition Agreement

After the elections in March this year and in a record breaking period of 8 months the Dutch government negotiated about a coalition agreement. This week they reached a final agreement and nuclear energy is an important element. Life time extension of Borssele NPP beyond 60 years and the construction of 2 new NPPs will be first steps to help us in tackling the energy transition challenges. A minister of Climate and Energy will be appointed. An energy and climate fund of 35 Billion euros will be set up for the coming 10 years of which 5 Billion is earmarked to pave the way for Nuclear. This is a historical moment for the Nuclear industry in the Netherlands, which was already in revival with the planning and construction of the PALLAS-reactor for medical isotope production and Materials testing in the province of Noord-Holland.

Long-Term Operation of Nuclear Power Plants in the US with Subsequent License Renewal

In the United States, it was recognized in the early 1980s that the topic of extending the operating licenses for nuclear power plants would need to be addressed.  This prompted activities at the NRC to consider a process for renewing licenses, research activities to demonstrate the feasibility of renewing licenses, and codes and standards activities. 

LTO of NPP Borssele

The Borssele Nuclear Power Plant is the only operating NPP in the Netherlands. It started commercial operation in 1973 and is therefore already 48 years in production. Long term operation is currently scheduled until 2034.

Licensing Strategies and Implications for Fuel and Materials

While relatively young in the context of traditional nuclear development, Kairos Power’s iterative approach and strong emphasis on early engagement with the regulator have yielded significant experience and tangible licensing results early in the project lifecycle. Kairos Power’s near-term focus is on U.S. licensing and deployment, but the lessons learned through KP-FHR development, testing, and licensing experience are also valuable under different regulatory regimes.

Terrestrial Energy Case NRG

Licensing at Terrestrial Energy

Terrestrial Energy has been engaged in the Canadian Nuclear Safety Commission’s (CNSC) Vendor Design Review (VDR) process since 2015 which is an optional service provided by the CNSC when requested by a vendor.

Challenges in the licensing process for new nuclear power plants

A key aspect in the planning of new-built of a nuclear power plant is licensing. To allow for clear investment decisions and the prevention of cost overruns, it is of paramount importance that a transparent and harmonized licensing framework is provided. It should be possible to provide all relevant requirements and insights of the risks at the beginning of the project.

Energy market studies more positive towards nuclear energy

Our nuclear innovation conference to be held in March next year will focus on what innovations are needed for nuclear energy progression. The relevance of this topic is once again demonstrated by the recent publication of IPCC and by the publication of a Market Consultation report by KPMG.

Insights from LTO safety cases, interview with Mr. Reed, EDF Energy

Jim Reed is the Chief Graphite Engineer in EDF. In this role he has strategic oversight in a particular part of the nuclear power station, the graphite core. The graphite core is one of the key life-limiting issues for the nuclear reactors in the UK. The work to better understand the lifetime is a combination of science and engineering, trying to understand key behavior at the atomic level and how the graphite core as a 1000+ m3 structure behaves in a seismic event. Continue reading for his point of view when it comes to UK lifetime extension activities and energy providers’ business strategies.
