France News7 (FN7) October 7, 2026 – Executive Summary: Sellafield Ltd has shared its approach to continuous improvement with more than 400 nuclear-sector leaders representing 38 countries at a World Association of Nuclear Operators General Meeting in Tokyo. Chief Operating Officer Roddy Miller outlined how the UK nuclear organisation encourages employees to identify better ways of working, learn from experience and solve problems collectively. The meeting also marked the launch of WANO’s Culture of Continuous Improvement Framework, designed to help nuclear organisations make learning and improvement part of everyday operations.

Sellafield Ltd used the international nuclear industry gathering in Tokyo to explain how it approaches continuous improvement and how the practice can be incorporated into normal working processes.

Chief Operating Officer Roddy Miller addressed the World Association of Nuclear Operators (WANO) General Meeting, which brought together more than 400 leaders from 38 countries. The meeting provided an international forum for nuclear organisations to discuss safety, skills development, risk management and technological developments.

The event also featured the launch of WANO’s new Culture of Continuous Improvement Framework, which is intended to support nuclear organisations as they seek to develop a working culture based on regular learning and improvement.

Sellafield’s contribution centred on the principle that improvement should not be treated as an isolated corporate initiative. Instead, the organisation said it should form part of everyday activities, including leadership, learning, problem-solving and the process of identifying and correcting weaknesses.

What did Sellafield tell international nuclear leaders about continuous improvement?

Sellafield said its experience demonstrates the importance of making continuous improvement part of ordinary working practices.

Miller explained that employees should routinely look for ways to improve how work is carried out, learn from previous experience and work with colleagues to resolve problems.

In remarks supplied by Sellafield, Miller said: “Continuous improvement cannot become another initiative, programme or campaign. It has to be part of normal work: how we lead, learn, challenge, solve problems and self-correct every day.”

The statement places continuous improvement within the wider responsibilities of an organisation rather than treating it as a temporary project.

For a nuclear operator, that approach is particularly connected with the need to maintain high standards of safety and performance. The Sellafield contribution focused on the processes through which people and organisations can continue learning from experience and identifying opportunities to improve.

The emphasis was therefore on behaviours and working practices rather than the introduction of a single improvement campaign.

What was discussed at the WANO General Meeting in Tokyo?

The WANO General Meeting brought together leaders from nuclear organisations across the world.

According to the information provided by Sellafield Ltd, participants discussed several areas relevant to the operation and management of nuclear organisations. These included safety, developing skills, managing risks and using new technology.

The international nature of the meeting was significant, with more than 400 leaders from 38 countries taking part.

WANO provides a mechanism through which nuclear organisations can exchange experience and learn from one another. Its activities are centred on sharing good practice and supporting improvements in nuclear safety and performance.

The meeting therefore provided an opportunity for organisations from different national and operational environments to consider common challenges and approaches.

Sellafield’s participation formed part of its longstanding relationship with WANO and its wider engagement with international nuclear organisations.

What is WANO’s Culture of Continuous Improvement Framework?

WANO launched its new Culture of Continuous Improvement Framework at the General Meeting in Tokyo.

The framework is intended to help organisations establish an environment in which learning and improvement become part of their ongoing activities.

Rather than viewing improvement as an occasional response to a particular problem, the framework focuses on developing a culture in which organisations regularly examine how they work and identify areas where performance can be strengthened.

The launch also complemented the message delivered by Miller, who argued that continuous improvement needs to be integrated into normal work.

The framework comes within WANO’s broader role of helping nuclear organisations learn from one another and apply good practice.

Its introduction provides a common point of reference for organisations seeking to strengthen their approaches to continuous improvement while continuing to operate within their own national and organisational environments.

How does Sellafield encourage its teams to improve their work?

Sellafield said its approach encourages teams to focus on three principal activities: finding ways to do things better, learning from experience and solving problems together.

These activities place employees at the centre of continuous improvement.

Looking for ways to do things better involves identifying opportunities to improve existing practices rather than assuming that established methods cannot be changed.

Learning from experience provides a second element. It means using what has happened previously to inform future decisions and working practices.

The third element is collaborative problem-solving. Sellafield’s description indicates that challenges should be addressed collectively rather than relying solely on individual responses.

Together, these practices form part of the organisation’s wider approach to continuous improvement.

Miller’s comments also connected improvement with leadership and the ability of teams to challenge existing practices. His statement referred to how organisations lead, learn, challenge, solve problems and self-correct as part of normal work.

Why is international cooperation important to the nuclear sector?

Nuclear organisations operate in different countries and regulatory environments, but they face a number of common challenges involving safety, performance, skills, risk and technology.

WANO provides an international mechanism for organisations to exchange knowledge and experience.

Sellafield has worked with WANO for more than 25 years. During that period, the relationship has enabled the organisation to learn from nuclear organisations in other parts of the world while also sharing its own experience.

The long-term relationship reflects the importance of international learning within the nuclear sector.

For organisations operating complex nuclear facilities, experience gained elsewhere can provide information about approaches to safety, management and performance. Equally, sharing lessons from their own operations allows organisations to contribute to wider industry learning.

Sellafield’s participation in the Tokyo meeting therefore represented both sides of that relationship: learning from international peers and sharing its own approach.

What did Roddy Miller say about embedding improvement into everyday work?

Roddy Miller’s central message was that continuous improvement should not be treated as another standalone initiative.

According to Sellafield’s account of the event, Miller said improvement must instead become part of normal work.

His statement specifically referred to leadership, learning, challenging existing approaches, solving problems and self-correction.

The distinction is important because a temporary programme can have a defined start and end, whereas a continuous-improvement culture is intended to operate on an ongoing basis.

Miller’s comments presented continuous improvement as a routine responsibility across an organisation rather than a separate activity assigned to a particular team.

The approach also connects improvement with organisational learning. When employees and leaders examine previous experience, identify problems and consider alternative approaches, lessons can potentially be incorporated into future work.

How does Sellafield’s approach relate to nuclear safety and performance?

The development is relevant to nuclear safety because continuous learning and performance improvement are closely associated with the way nuclear organisations manage complex operations.

Sellafield said that working together allows nuclear organisations to continue improving safety, performance and the way they support their people.

The company’s contribution did not present continuous improvement as a substitute for existing safety arrangements. Instead, it described improvement as part of the way organisations operate and learn.

WANO’s role is also based on international cooperation and the sharing of good practice. The Culture of Continuous Improvement Framework adds another mechanism through which participating organisations can consider how learning and improvement are embedded in their working cultures.

The focus on people is also significant. Sellafield’s approach involves encouraging teams to identify improvements, learn from experience and solve problems collectively.

How long has Sellafield worked with WANO?

Sellafield has worked with WANO for more than 25 years.

The relationship has provided opportunities for the organisation to learn from nuclear organisations around the world and share its own experience with international counterparts.

That long-standing engagement provides context for Sellafield’s participation in the Tokyo meeting.

The relationship is not limited to the latest meeting. Instead, the company’s contribution forms part of a longer period of international cooperation within the nuclear sector.

Sellafield’s involvement also illustrates how nuclear organisations can use international networks to exchange experience and contribute to industry-wide learning.

What does the new framework mean for nuclear organisations?

WANO’s Culture of Continuous Improvement Framework provides a structured approach to an issue that was central to the discussions at the Tokyo meeting.

For participating nuclear organisations, the framework can serve as a reference for considering how continuous improvement is supported within their own workplaces.

The information released by Sellafield does not state that the framework imposes a single operational model on every organisation. Instead, it describes the framework as an approach intended to help organisations learn and improve every day.

This corresponds with Miller’s argument that continuous improvement needs to be incorporated into normal work.

The wider significance of the framework therefore lies in encouraging organisations to consider culture, leadership, learning and problem-solving alongside technical and operational performance.

Why does the development matter for the international nuclear industry?

The Tokyo meeting brought together representatives from 38 countries, giving the discussion an international scope.

The participation of more than 400 leaders also demonstrates the scale of the WANO network and the number of organisations involved in discussions around nuclear safety and performance.

The launch of the new framework adds to those discussions by placing continuous improvement at the centre of organisational learning.

Sellafield’s experience provides one example of how the principle can be applied in practice. Its emphasis on everyday behaviours means that improvement is connected with the actions of teams and leaders rather than being limited to formal improvement projects.

The exchange of such approaches is one of the functions of international nuclear cooperation.

What is the background to Sellafield’s international cooperation with WANO?

Sellafield is a major UK nuclear organisation and has maintained a relationship with WANO for more than 25 years.

WANO was established to support cooperation among nuclear operators and facilitate the sharing of experience and good practice.

The organisation’s international network allows nuclear organisations to learn from operational experience elsewhere and consider how lessons can contribute to improvements in their own activities.

Against that background, Sellafield’s presentation in Tokyo was part of a broader process of international knowledge-sharing.

The meeting’s focus on safety, skills, risk management and technology also reflects the range of issues facing nuclear organisations as they seek to maintain performance and develop their workforce.

The introduction of the Culture of Continuous Improvement Framework represents a further step in WANO’s efforts to support organisational learning and improvement.

What could this development mean for nuclear organisations and their workforce?

The immediate effect is likely to be continued attention to how nuclear organisations embed improvement into everyday working practices.

For nuclear-sector leaders, the framework provides a common basis for considering how organisational culture supports learning, challenge and problem-solving.

For employees, the approach described by Sellafield places emphasis on identifying opportunities for improvement and learning from experience.

For the wider nuclear industry, greater sharing of experience can help organisations compare practices and learn from approaches used in other countries.

The development does not establish a prediction about specific operational outcomes. However, based on the information provided by Sellafield, the stated objective is clear: international cooperation and continuous improvement are intended to support better safety, performance and support for people working in the nuclear sector.
