Implementing Agreements: legal contracts

Ensuring energy security and addressing climate change issues in a cost-effective way are the main challenges of energy policies and in the longer term will be solved only through technology cooperation.

To encourage collaborative efforts to meet these energy challenges, the IEA created a legal contract – Implementing Agreement – and a system of standard rules and regulations.

This allows interested member and non-member governments or other organisations to pool resources and to foster the research, development and deployment of particular technologies

Recent renewal of the Implementing Agreement

In the past twenty years the Implementing Agreement has played a key role in boosting RFP research though the coordination of international research and the promotion of cooperation in RFP experiments and theory.

The IA terms is 5 years, and the previous one expired in April 2010.

The IA Executive Committee decided to ask for a 5 years renewal (2010-2015).

The case was made and defended in front of the two relevant bodies:

– IEA Fusion Power Coordinating Committee (FPCC), Paris, February 23-24, 2010

– IEA Committee on Energy Research and Technology (CERT), Paris, March 4, 2010

Improved confinement is comparable to that expected for a tokamak of the same size and current.

• Use same Ip, n, Pheat, size, shape to define a tokamak reference.

• is 10 times smaller in the RFP compared this way.

A growing and productive community

The RFP community has obtained in the last decade a large number of achievements in terms of:

– Scientific excellence;

– Performance of its devices;

– Understanding and advancing the RFP as a fusion player;

– Education and training;

– Ability of interacting with the broader fusion community, talking the same language and contributing to the investigation of key issues for tokamak and stellarator, and for ITER and attracting fusion scientists to work on the RFP;

– Ability of sharing resources with the broader plasma community;

– Communication and recognition;

– Growth of the groups

Page 34: A volcano can be fun….if its quite jumping down from Etna top

Advancing RFP, with full integration in the international fusion effort

Impressive improvement in confinement (and in its understanding), with (among others):

– discovery of the new helical state and

– proof of principle experiments like PPCD indicating the possibility of healing magnetic turbulence driven transport;

MHD stability feedback control:

– leading-edge contribution to the tokamak, joint experiments with AUG, DIII-D, JT-60SA, ITER relevant projects;

Magnetic self-organization:

– leading role in the US NSF Centre for Magnetic Self Organization, collaboration with astrophysics;

Three-dimensional physics, starting a positive interaction with the stellarator community to bridge gaps and build a common knowledge basis

– (KIT experiments on LHD, stellarator scientists @this workshop, RFP scientists at IEA stellarator workshop)

The challenge

Page 40: A volcano can be fun….if its quite jumping down from Etna top

The Great Green Wall Projects

Two major projects on human forestation to help preserve our environment:

– In 1978, China launched the Great Green Wall initiative, scheduled for completion in 2050. The goal is tree coverage of about 42 percent of China's landmass, with a “wall” of trees 4500 km long, mainly to hold back the Gobi desert

– A wall of trees is under “construction” which will stretch from Senegal to Djibouti as part of a plan to thwart the southward spread of the Sahara desert (7000 km long).

In 2005 the Food and Agriculture Organization (FAO) of the United Nations, which monitors the state of the world's forests every few years, reported that 13 million hectares of global forests are lost annually, including 6 million hectares of what are described as primary forests-some of the most biologically diverse ecological systems in the world.

Bio-diversity is a value

Human planted trees can not substitute human made de-forestation

Human forestation is extremely important, but it is not enough. Mankind can never replace the diversity provided by nature

Alternatives to help achieving fusion faster

Fusion is close, but there are still complex problems to be solved. We need a joint international focused effort to make fusion a successful story.

Massive efforts are crucial and extremely important, but we should not forget the lesson from nature: diversity is a big value.

The fusion community has a main line, the tokamak, where most of the resources need to be concentrated, but alternatives like stellarator and RFP are crucial to provide diverse approaches and explore different regions of the parameter space, and to make the achievement of fusion faster.

Our challenge is to be dynamic and fruitful players in this diverse fusion world.
