Reference excerpt

The Groupement des scientifiques pour l'information sur l'énergie nucléaire GSIEN (Association of Scientists for Information on Nuclear Energy) is a multidisciplinary not-for-profit association of independent scientists who aim to spread information about the nuclear industry in France founded on December 15, 1975. In addition to providing a structure within which independent evaluations can take place, GSIEN aims to ensure that the French nuclear industry, one of the World's largest, provides open and honest information. In 1977 GSIEN was first to provide an explanation of the causes and consequences of the Three Mile Island accident, while the authorities tried to play-down the incident, however GSIEN came to prominence at the time of the 1986 Chernobyl disaster when the press and public found that their independent information helped to compensate for the shortcomings in the official information. They subsequently became widely recognised after many of their members contributed to various overseas projects.

History GSIEN was founded in the wake of the launch in 1974 of the Messmer Plan to switch all of France's electricity generation to nuclear power, which took place without public or parliamentary debate. The announcement of the Messmer Plan caused a split in the scientific community between those physicists (generally older) who favoured the plan, and those (generally younger) who were concerned about the potential risks, leading to l’Appel des 400 (the appeal of the 400), a petition signed initially by over 400 scientists, and ultimately by around 4,000, expressing their concern over a number of issues including 'secrecy' and 'official propaganda'. GSIEN was created following this petition, inspired in part by model of the Union of Concerned Scientists in the United States, with the objective of disseminating information to 'prevent nuclear officials from turning information into propaganda'. In 1998 Monique Sené, nuclear physicist, one of GSIEN's co-founders and its president, was awarded the National Order of the Legion of Honour for her work as anti–nuclear power activist.

Activities

Publications Since its first edition in June 1976, GSIEN has published over 250 editions of its quarterly newsletter, la Gazette Nucléaire (the Nuclear Gazette). GSIEN has also published a number of books including Electro-nucléaire : danger (1977, ISBN 978-2-02-004711-1), Plutonium Sur Rhône (1981, ISBN 978-2-901968-47-4)

Technical expertise GSIEN members have been invited by several Local Information Commissions to participate in a number of 10-yearly nuclear plant inspections, including those at Fessenheim, Golfech Nuclear Power Plant and Blayais Nuclear Power Plant, as well as in a various other assessments.

Worked examples

Example 1 — a first encounter with Groupement des scientifiques pour l'information sur l'énergie nucléaire

Start with the simplest possible case. Write down what Groupement des scientifiques pour l'information sur l'énergie nucléaire claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Groupement des scientifiques pour l'information sur l'énergie nucléaire before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Groupement des scientifiques pour l'information sur l'énergie nucléaire ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Groupement des scientifiques pour l'information sur l'énergie nucléaire

In research: Groupement des scientifiques pour l'information sur l'énergie nucléaire appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Groupement des scientifiques pour l'information sur l'énergie nucléaire in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Groupement des scientifiques pour l'information sur l'énergie nucléaire is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anti-nuclear organizations, Nuclear energy in France, Organizations established in 1975, so understanding it makes those chapters shorter.
In everyday life: Look for Groupement des scientifiques pour l'information sur l'énergie nucléaire outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
