ITER Nature BigotITER director-general Bernard Bigot explains how he will strengthen leadership and management to refocus the project's aim of harnessing nuclear fusion. Ten years ago this month, China, the European Union, Japan, South Korea, Russia and the United States agreed on the location for the world's largest nuclear-fusion experiment: ITER, the International Thermonuclear Experimental Reactor, which they had decided to build jointly. India joined six months later. The project's aim is to fuse two isotopes of hydrogen — tritium and deuterium — to deliver a powerful, clean source of electricity. This requires the containment of plasma at temperatures ten times higher than the Sun's core.

Roughly €4-billion (US$4.4-billion) worth of construction contracts and €3 billion in manufacturing contracts worldwide are under way. The first large components are being delivered to the site at St-Paul-lez-Durance in southern France for assembly.

The project has been plagued by delays and difficulties. The seven ITER members are designing and manufacturing key components. When deadlines or standards are not met, the knock-on effects across the whole project can be dire. Late contracts for tools have kept one of the largest buildings — in which ring-shaped magnets up to 24 metres in diameter will be manufactured — inactive since its completion in December 2011. When problems arise, bickering ensues as to who should foot the bill.

I have been a privileged observer from the start, as the high representative for ITER in the host country, France. Because France itself is not a formal member of ITER — it contributes to the European Union budget for the project and to some basic site infrastructures — I, like many others, could only witness with frustration the slipping of the schedule despite the best efforts of the more than 2,000 dedicated people working on ITER.

Since becoming director-general of the ITER Organization, which manages the project, in March, I have realized that ITER's main problem has been the lack of a clearly defined authority to oversee the entire project. Having someone firmly in the driving seat, with the power to take decisions, is the key to success in any project. I have learned this over the course of my career — through building an innovative higher-education institute from scratch (École Normale Supérieure de Lyon) and as head of the French Alternative Energies and Atomic Energy Commission for 12 years.

Here, I set out my vision for ITER. The project must overcome its organizational problems so that it can deliver on its promise of taking a firm step towards harnessing an unlimited, continuous, safe and clean source of energy. These lessons apply to any major international collaboration.

A rocky transition

Since construction began on ITER five years ago, it has become increasingly apparent that the project's management structure is poorly adapted to the challenge of building a large, complex research facility.

Take the 8,000-tonne ITER vacuum vessel, the doughnut-shaped central component of the 'tokamak' reactor that houses the fusion reactions. Seven of its nine sectors are to be manufactured in Europe and two in South Korea, with each region or country taking responsibility for how they are sourced. Having two contractors is a risk, because each has its own manufacturing techniques; duplicating the processes that validate the quality and function of components, such as fabricating mock-ups, adds to the cost; and the tolerance margins that each contractor has adopted differ. Yet the ITER Organization is responsible for assembling the final vessel.

Any modification has a cascading impact on other components. This has generated an almost endless to-and-fro between the ITER Organization, procuring member countries and suppliers. This situation has already cost ITER tens of millions of euros.

People know there is a problem. A 2013 management-assessment report described the decision-making process at the ITER Organization as “ill-defined and poorly implemented”. The management structure has proved incapable of solving issues and responding to the project's needs, so accumulating technical difficulties have led to stalemates, misunderstandings and tension between staff around the world. These problems stem from how the organization was set up through an international treaty in 2007.

First, deputy director-generals from each member country or region were given responsibility for one large technical or administrative department of the ITER Organization. These managers also acted as official representatives for their nation or nations.

Second, the procurement of components, systems and buildings is split among the member states so that each could gain experience. The work is assigned according to the industrial capacities of members and a cost-sharing scheme that allocates 45.5% to the European Union (as the host) and just over 9% to each of the others. Each member has a procurement centre, called a domestic agency, that is legally and administratively independent from the central ITER Organization.

The organization is responsible for validating the design of the facility; compliance with safety regulations; coordination of manufacturing and quality control of the numerous components; their on-site assembly; and later, the operation of the facility.

Paperwork abounds. For each work package, the organization signs a procurement arrangement with the relevant domestic agency that details all technical specifications and management requirements. The domestic agency then launches a call for tender to select a company or consortium to do the work.

Such a system has benefits: procurements are shared widely, industries in member states develop, spin-offs are generated, jobs are created and specialists trained. Intellectual property generated by the project is shared. But it has become ever more obvious — as successive reports have pointed out — that the costs outweigh the benefits.

Team building

I accepted the job of director-general on the condition that the position was newly invested with full authority over the whole project. Authority and a radical redefinition of how the organization interacts with the domestic agencies are at the core of the action plan that I submitted to the ITER Council in January, before my formal appointment.

The domestic agencies will retain their distinct legal identity. But they will be integrated functionally and put on an equal footing with the departments in what we now call the ITER Organization Central Team, based in St-Paul-lez-Durance.

A new executive project board brings together the managers of the central team and the domestic agencies at least once a month, in person or by video conference. Disputes can be settled and decisions taken swiftly.

Technical issues — from construction to radioprotection and cryogenics — are handled by project teams of 20 to 50 people, depending on the scope. They comprise staff from the central team and domestic agencies on the basis of technical need, professional skills and experience. When necessary, representatives of contracting industries participate.

It is too late and costly to reverse decisions that have already been made — such as how the tokamak vacuum vessel is fabricated. Problems must be solved downstream; in April, the executive project board formed a joint ITER Organization and domestic agency project team to anticipate and overcome integration and assembly issues. Had this decision been taken earlier it would have saved time, money and frustration.

The ITER Organization and domestic agencies together employ 2,000 people. Changing how ITER is managed will alter its culture. I aim to foster an atmosphere in which each party or individual feels personally responsible for the whole project, not just their area of competence. One of my first actions after becoming director was to address the staff of each domestic agency. The most striking moment was in a video session with all four Asian agencies. For the first time, colleagues in Japan, India, South Korea and China saw the faces of their counterparts, changing the dynamic towards a shared global ambition.

I am also implementing a new type of mobility throughout the project. This will enable appropriate domestic-agency staff to be temporarily seconded to the ITER site, or central-team staff to be assigned to domestic agencies.

The ITER Council has agreed to this new organization. I am grateful for their strong support and the progress already made in solving technical issues and improving communication.

Discretionary fund

There is still much more to do. Authority requires the financial means to exercise it. I have asked for the creation of a reserve fund, to be put at my disposal. Each domestic agency will contribute, allowing me to take quick and efficient decisions to address issues as they arise. Terms of reference will be presented to the council in June for approval. The money will be drawn from the contributions of the ITER members in proportion to the amount they pay in.

In my experience of industrial projects, a reserve fund must comprise about 20% of fabrication costs over the duration of construction. In my view, it was naive not to establish such a fund much earlier in ITER's history.

Before the end of this year, I am expected to submit, along with all stakeholders, an updated, robust and reliable schedule to the ITER Council, and a cost and risk analysis. With renewed management and a streamlined organization, we are now ready to prepare for the assembly and commissioning phase, the step before fusion switches on.

Further delays and costs are inevitable. ITER will meet these challenges if it has the unanimous political support of the seven members, on the basis of the long-term value of fusion technology.

All of us at ITER have a huge, historic responsibility. The project may be the last chance we have this century to demonstrate that fusion is manageable.
