There is no doubt that the first reactors in France, those in the UNGG industry, shut down towards the end of the 70 years, which had to represent in total 2000MW installed, were built to satisfy military needs in addition to their generating function.

But the following approximately 60000MW (PWR sector) are to my knowledge quite incapable of producing "military grade" plutonium.

The prostitute's redeeming a virginity seems to me to be a very old story.

Switzerland: The dismantling of nuclear power plants will cost more than expected

December 21, 2017

The costs of decommissioning nuclear power plants and managing radioactive waste have been underestimated in Switzerland, according to a study. They would be higher than 700 million.

Independent experts examined the 2016 cost study and concluded that 23,5 billion should be used instead of 22,8 billion. Published about a year ago, the initial study was conducted by swissnuclear on behalf of the Commission for the Decommissioning Fund and the Waste Management Fund (STENFO).

Dismantling studied abroad
Nuclear waste management is based on the polluter pays principle. Plant operators must therefore supply two funds to cover the management of radioactive waste and the future dismantling of the plants.

In their review carried out over the past few months, independent experts compared the results of the study to the costs of decommissioning and waste management from foreign nuclear power plants, STENFO details Thursday. They concluded that while swissnuclear's cost calculation is "sound and correct", some points need to be adjusted.

I never said that nuclear power was inflexible, but that it posed problems of operations and additional costs. There are only artists like you not to admit it or laugh at it. And you poor argumentator, you call me a "conspiracy"?

@janic

I would like to be young enough not to have known the beginnings of nuclear power in France; that is not the case ... That said, yes, nuclear was immediately recovered by the military and developed as a killing machine; there are even some who have had the ferocity to experiment on a civilian population without any military justification, with 200 000 dead. But do you know, in the history of mankind, a technical progress that did not first serve wars? Me, I do not know, since the discovery of bronze (and even before); that's enough to disqualify wars and military, but not science or technology.
And it is true that the Graphite-Gaz sector was chosen, despite the known intrinsic dangers, because it allowed an easy production of plutonium for military purposes; in France as in the USSR, with the results that we know, including two fusions of heart in France and Chernobyl in the USSR. Other channels were, and are always possible, much safer and more interesting.

On the WHO Chernobyl study
You obviously do not know the methods used in epidemiology and public health studies. No one is restricted to the personal situations of individuals, but the principle is to compare the prevalence and incidence of a population at risk with that of an identical population not subject to this risk; Cohort studies are used to specify these data. The study at Chernobyl was remarkably dense and long, by a multi-disciplinary multinational team of high expertise, and the results are precise and detailed, with discoveries of paradoxical phenomena astonishing, and carrying lessons on the conduct to be held. But all this is much better explained in the full text of the study (unfortunately published in English), that I invite you to read (even if you do not agree, you will learn a lot).
Reassure yourself, the experts involved did not belong to the WHO majority (but these stories of global conspiracy tend to make me smile, even if some conflicts of interest are often very real).

OK for the smic

There remains the question of the "virtue" of nuclear power, or coal ... so let's leave the virtue aside, I lost mine some time ago (and I derive more pleasure than dismay) , and I see that it is the same for a lot of people ...

The question today is not stated in terms of virtue, but of efficiency, it is more down-to-earth. And it's subject to constraints that, it seems to me, are a little too neglected by various stakeholders in this forum. Concretely, our country is, like all the others, in the obligation to leave carbon energies; for us, on the 1500 TeraWh consumed annually, convert about 1 000 TeraWh, twice the electricity consumption ... It's huge, not easy, very expensive, painful; for some activities, you do not even know how to do it. And some cling to the 24 TeraWh provided by the new EnR, and propose to remove more 500 TeraWh produced by the nuclear.
But, with similar reasoning, are we not a little crazy? Have we taken the measure, even approximate, of the task at hand? For me, the priorities are obvious: let us fool the peace with the nuclear power, which is not dangerous, not very expensive, and has the merit to exist and to provide us with the essence of the electricity ... Let's treat him the peace Even Fessenheim ... Anyway, even with everything, it will not be enough ...
And let's hurry to invest in what will be the most effective way to get out of oil, gas and coal, without wasting anything and making the best choices; which means:
- a global, intense, determined energy saving and sobriety (and it is not bikes or led bulbs ...)
- optimization of all that is carbon-free energy production (in this context, there is room for renewable energy)
- unbridled development of new technologies producing or saving energy.

Inside, virtue, aesthetics, emotional or ideological dogmas have little place ... They are for the rich, the rich, and we are not ... By cons, a maximum of social justice and strong solidarity with the less well endowed countries are a prerequisite ...

Bardal, finally here I join you and what you evoke and largely within our reach but it is necessary to want it and to look forward ... for a guy "to mow" it is even more difficult ... we continue to heat the street with an oil stove that needs to be filled with fuel every day to bring only a little warmth alongside its presence ...

@janic
. But do you know, in the history of mankind, a technical progress that did not first serve wars? Me, I do not know, since the discovery of bronze (and even before); that's enough to disqualify wars and military, but not science or technology.
Unfortunately you say true, but it ended up becoming the justification for a regrettable situation considering that it is the only solution to remember.
On the WHO Chernobyl study
You obviously do not know the methods used in epidemiology and public health studies. No one is restricted to the personal situations of individuals, but the principle is to compare the prevalence and incidence of a population at risk with that of an identical population not subject to this risk; Cohort studies are used to specify these data.
I humbly admit that nuclear is not my priority in my favorite subjects. This is also why when one invokes studies of cohorts, multidisciplinary teams and touti qant, I am wary knowing, by experience, that this often hides a one-way speech. Read the topic on vaccinations where the same principles are mentioned with its own difficulties of interpretation and also to want to defend this or that system.
But epidemiological studies can be piped like any other topic when only one point of view, majority, is imposed on the populations, naive and too gullible, by an official speech which they have little the possibility to analyze and possibly to contest.
The study at Chernobyl was remarkably dense and long, by a multi-disciplinary multinational team of high expertise, and the results are precise and detailed, with discoveries of paradoxical phenomena astonishing, and carrying lessons on the conduct to be held. But all this is much better explained in the full text of the study (unfortunately published in English), that I invite you to read (even if you do not agree, you will learn a lot).
I would already have to read English which is not the case. Others probably did and analyzed. What interests me is what other "experts" say, for comparison.
Reassure yourself, the experts involved did not belong to the WHO majority (but these stories of global conspiracy tend to make me smile, even if some conflicts of interest are often very real).
We must stop with these stories of plot at all ends of fields. It's like invoking the fact that associations that analyze consumer products are making a plot because they point out the defects that manufacturers are careful not to point out (for example planned obsolescence). The reality is unfortunately much simpler (not simplistic). ) it is simply human where everyone defends his or her choice of interests and their convictions or interests, which are not indicators of truth for all that, and it is valid for all convictions and opinions.
The question today is not stated in terms of virtue, but of efficiency, it is more down-to-earth.
Efficiency as an argument! An atomic bomb is much more effective than a field war, does this justify a recommendation of effectiveness?
See, for example (the subject is evoked by the TV behind me) the effectiveness of crop treatment products and boomerang effect, the catastrophic mortality of bees and generally on all pollinating insects.
And it's subject to constraints that, it seems to me, are a little too neglected by various stakeholders in this forum.
Of course, but constraints that are "self-centered" preoccupied by the direct impact of the sector on its environment without taking into account all possible indirect aspects. Another comparison: if fishing was not constrained by decrees, there would be little fish to sin and limit or prohibit this or that action, also serves to protect the populations concerned. However, the nuclear power had no restrictive constraint which blocked the early use of alternative solutions, of course.
Concretely, our country is, like all the others, in the obligation to leave carbon energies; for us, on the 1500 TeraWh consumed annually, convert about 1 000 TeraWh, twice the electricity consumption ... It's huge, not easy, very expensive, painful; for some activities, you do not even know how to do it. And some cling to the 24 TeraWh provided by the new EnR, and propose to remove more 500 TeraWh produced by the nuclear.

From his memory, he has never been able to interrupt the nuclear industry in spite of its dangers, but to replace this technology progressively and as quickly as possible.
But, with similar reasoning, are we not a little crazy? Have we taken the measure, even approximate, of the task at hand? For me, the priorities are obvious: let us fool the peace with the nuclear power, which is not dangerous, not very expensive, and has the merit to exist and to provide us with the essence of the electricity ... Let's treat him the peace Even Fessenheim ... Anyway, even with everything, it will not be enough ...
Bad reasoning! Filling the peace with the nuclear power is like invoking to make peace with the drug (not dangerous to the population) to tobacco or alcohol or to the terrorists who make only very few victims globally, whereas besides immense efforts are being made to prevent the death of a single individual every year by an absurd sanitary policy.
And let's hurry to invest in what will be the most effective way to get out of oil, gas and coal, without wasting anything and making the best choices; which means:
- a global, intense, determined energy saving and sobriety (and it is not bikes or led bulbs ...)
- optimization of all that is carbon-free energy production (in this context, there is room for renewable energy)
- unbridled development of new technologies producing or saving energy.

Here we meet (I mean at the level of ecologists obviously!) But if it was so simple it would be long since! and the last point is only wishful thinking especially for its frantic side obviously! on the other hand you do not evoke anything to get out of the nuclear!
Inside, virtue, aesthetics, emotional or ideological dogmas have little place ... They are for the rich, the rich, and we are not ...
except that virtue, aesthetic, emotional are powerful engines of societies, especially human, and we can not reasonably do without!
On the other hand, a maximum of social justice and a strong solidarity with the less well endowed countries are a prerequisite ...
It's oh how true! I argue (at my small level) so that conscience is taken on the impact of agriculture, and especially livestock, on pollution, the global waste (at the expense of less favored populations elsewhere) much more serious than certain pollution industrial. A frantic development of these food industries would hardly be offset by another frantic development of technologies, even though it is often the technology that fucks us.

Nuclear: EDF and Veolia join forces in dismantling and waste

Posted on 26 / 06 / 2018 VILLEPINTE (Seine-Saint-Denis) (Reuters)

EDF and Veolia signed Tuesday a partnership in the nuclear field to jointly develop solutions for reactor dismantling and radioactive waste treatment, in France and abroad.

This agreement relates more specifically to the natural gas graphite gas (UNGG) reactor sector, of which EDF is currently dismantling six units at Bugey (Ain), Chinon (Indre-et-Loire) and Saint-Laurent-des-Eaux ( Loir-et-Cher), said the two groups in a statement.

Veolia will provide the public electrician with its expertise in remote intervention technologies (robotics) to design and produce solutions that will allow access to the heart of UNGG reactors, cut and extract components "in optimal safety and security conditions ".

The partnership between the two groups, signed at the occasion of an international nuclear exhibition near Paris, also provides for the development of an industrial solution for vitrification of low and intermediate-level waste using Veolia technology.

The 1 world number of the treatment of water and waste had already concluded in 2013 a strategic agreement with the Commissariat for the atomic energy (CEA) in the cleansing and the dismantling of the nuclear installations.

In addition, 2017 grouped all of its activities into a single entity - Veolia Nuclear Solutions - dedicated to the remediation, decommissioning and treatment of nuclear waste, which employed 900 people in 2017 against less than 100 in 2015.

Veolia, now active in the nuclear sector in the United States, France, the United Kingdom, Canada and Japan, is also the only international operator to work in Fukushima on behalf of TEPCO.

Launch of tenders for the dismantling of the Dounreay nuclear site in Scotland.

Dounreay decommissioning framework contracts awarded

24 April 2019

Dounreay Site Restoration Limited (DSRL) has awarded six framework contracts - potentially worth up to a combined GBP400 million (USD 518 million) - for decommissioning services at the Dounreay site in Scotland. Among the major projects expected to be delivered are the construction of a shaft reduction, shaft and silo decommissioning and the demolition of historic active laboratories.

The 524 MWe nuclear reactor of Onagawa 1 (Japan) will be dismantled.

Tohoku submits decommissioning plan for Onagawa 1

02 August 2019

Tohoku Electric Power Company has applied to Japan's Nuclear Regulatory Authority (NRA) for approval of its decommissioning plan for 1 unit of the Onagawa nuclear power plant in Miyagi Prefecture. The company announced in October 2018 its decision to scrap the unit as it said it would be too expensive and time-consuming.

Unit 1 of the 524 MWe Boiling Water Reactor (BWR) that began operations in 1984 is a different design (825 MWe) BWR units there, which began operating in 1995 and 2002, respectively. Tohoku also operates a single 1100 MWe BWR at its Higashidori plant in Aomori Prefecture, which started operation in late 2005. Tohoku plans to restart 2 and 3 units at the Onagawa plant, as well as its Higashidori plant.

Last October, Tohoku said to be unique on Onagawa 1 is the subject of such restrictions in the field of equipment, such as fire extinguishing equipment, power supply equipment and alternative water injection pumps. It was decided to decommission the unit after its inception and it would be restarted. Onagawa 1 became the tenth operable Japanese reactor to be declared for decommissioning since the March 2011 Fukushima Daiichi accident.

Its decommissioning plan for the unit, which it submitted to the NRA on July 29, outlines the facilities and equipment to be dismantled and a timetable for completing the work. Decommissioning will take over 34 and will be carried out in four stages.
