NUCLEAR: THE SLOW DEATH OF FAST REACTORS
Nuclear: The slow death of fast reactors
Fast neutron reactors are “poised to become mainstream” according
to the World Nuclear Association. The Association lists eight “current”
fast reactors although three of them are not operating. That leaves
just five fast reactors ‒ three of them experimental.
Fast reactors aren’t becoming mainstream. One after another country
has abandoned the technology. Nuclear physicist Thomas Cochran summarises
the history: “Fast reactor development programs failed in the: 1)
United States; 2) France; 3) United Kingdom; 4) Germany; 5) Japan; 6)
Italy; 7) Soviet Union/Russia 8) U.S. Navy and 9) the Soviet Navy. The
program in India is showing no signs of success and the program in China
is only at a very early stage of development.”
The latest setback was the decision
of the Japanese government at an extraordinary Cabinet meeting on
September 21 to abandon plans to restart the Monju fast breeder reactor.
Monju reached criticality in 1994 but was shut down in December 1995
after a sodium coolant leak and fire. The reactor didn’t restart until
May 2010, and it was shut down again three months later after a fuel
handling machine was accidentally dropped in the reactor during a
refuelling outage. In November 2012, it was revealed that Japan Atomic
Energy Agency had failed to conduct regular inspections of almost 10,000
out of a total 39,000 pieces of equipment at Monju, including
safety-critical equipment.
In November 2015, the Nuclear Regulation Authority declared that the
Japan Atomic Energy Agency was “not qualified as an entity to safely
operate” Monju. Education minister Hirokazu Matsuno said on 21 September 2016 that attempts to find an alternative operator have been unsuccessful.
The government has already spent 1.2 trillion yen (US$12bn) on Monju. The government calculated that it would cost another 600 billion yen (US$6bn) to restart Monju and keep it operating for another 10 years.
Decommissioning also has a hefty price-tag ‒ far more than for conventional light-water reactors. According to a 2012 estimate by the Japan Atomic Energy Agency, decommissioning Monju will cost an estimated 300 billion yen (US$3bn).

КРАСНЫЕ МАКИ
на мотив песни «Маки»
На Чернобыльских местах пустота.
Над городом Припять тишь.
Словно не было АЭС, но АЭС
Похоронена на дне тишины.
И, казалось бы, всему вышел срок.
25 лет менялась в море вода,
А как выйдешь, как шагнешь за порог
И от маков не уйти никуда.
Маки, маки, красные маки,
Горькая память земли.
Неужели вам снятся пожары,
Неужели вам снятся пожары
И те, кто там навек полегли.
PAPAVERI ROSSI
sul motivo della canzone «Papaveri»
Nei luoghi di Cernobyl c’è il vuoto.
Sopra la città di Pripjat’ tutto tace.
Come se non ci fosse una Centrale,
Ma essa è seppellita sul fondo del silenzio.
E pare come se tutto avesse fatto il suo tempo.
Per 25 anni l’acqua si è cambiata nel mare,
Ma come entri, come oltrepassi la soglia,
Non potrai mai più evitare i papaveri.
Papaveri, papaveri, papaveri rossi,
L’amara memoria della terra.
Davvero vi appaiono in sogno gli incendi?
Davvero vi appaiono in sogno gli incendi
E coloro che giacciono là in eterno?06/06/16
I QUATTRO REATTORI - ЧЕТЫРЕ РЕАКТОРА

Il
collegamento tra l’uomo e dio è la creazione. In maniera biunivoca.
Dall’alto dio crea e manda giù, dal basso l’uomo crea cercando di
spedire su. Quattro ganci pendono dall’alto. Pare sì, che questo dio
l’unico aiuto che abbia potuto inviarci, dal suo alto, più che il suo
dito che incrocia il nostro nella luce della cappella sistina, è il
gancio di salvezza che cala nel bianco dell’esplosione del reattore
lenin. Perché in questo caso, in questa sofferenza, se dio lo avesse, un
volto, non lo vedremmo, solo nube, cielo grigio cupo di vergogna; e se
le avesse le braccia sarebbero ganci come mani di scheletri che pendono
dal cielo.
Giorgio Anastasio, documentarista
Украина, в нескольких метрах от входа Чернобыльской АЭС
Связь
между человеком и богом – сотворение. Взаимно однозначное соответствие.
Свыше – бог сотворяет и отправляет вниз, снизу – человек сотворяет,
пытаясь отправлять вверх. Кажется, да, что этот бог единственную помощь,
которую он смог отправить нам, с его высоты, это не столько его палец,
скрещивающий с нашим при свете Систинской капеллы, а спасательный крюк,
опускающийся в белизну взрыва реактора Ленин. Потому что в этом случае, в
этом страдании, если бы бог имел лицо, мы не видели бы его, только
туча, серое небо, мрачное от позора; и если бы имел руки, они были бы
крюки, будто руки скелетов, висящих на небе.

CHERNOBYL: LE TOPPE AL DISASTRO 29 ANNI DOPO
Chernobyl:le toppe al disastro 29 anni dopo
Il New Safe Confinement è l’enorme
costruzione che 29 anni dopo sorge a circa 180 metri dal reattore numero
4; si tratta di due blocchi che una volta completati saranno “montati”
al di sopra della primitiva struttura tramite l’uso di binari appositi.
La struttura arriverà a misurare in altezza 110 metri, con una larghezza
di 165 e 260 metri in totale. Il costo stimato è di 1,5 miliardi di
euro ed è stato coperto dai finanziamenti gestiti dalla Banca europea
per la ricostruzione e lo sviluppo.
I lavori sono iniziati nel marzo 2012,
dopo che Novarka, un consorzio di imprese francesi è risultato vincitore
delle gare d’appalto. Il progetto ha visto la collaborazione
cosmopolita di circa mille menti di nazionalità diversa, tra le quali
operai e ingegneri italiani. Tra i protagonisti connazionali la Cimolai,
azienda friulana specializzata in costruzioni metalliche, si è occupata
delle parti in acciaio, realizzando 25 mila tonnellate di tubi, corpo
dell’intelaiatura che andrà ricoperta con pannelli in resina al fine di
bloccare l’agglomerarsi delle particelle radioattive.

ROSATOM'S NEW "ROADMAP" SLASHES NUMBER OF NEW REACTORS, BUT LEAVES LOOSE ENDS ON SHUT DOWNS
Rosatom’s new ‘roadmap’ slashes number of new reactors, but leaves loose ends on shut downs
Russia’s state nuclear corporation Rosatom announced at a major international conference that it would be slashing its ambitious plans to construct nearly three dozen nuclear reactors by 2020 in half, cutting the number to a more humble 12.
The AtomEco conference
late last month highlighted a number of issues facing the Russian
nuclear industry, from nuclear waste and spent nuclear fuel handling,
which was discussed at length by Bellona’s Alexander Nikitin, to citing
permanent repositories for spent nuclear fuel.
Nikitin said the AtomEco conference was a sign that relations between
Rosatom and environmental organizations were undergoing a change for
the better, thanks to management system “that is enacting a policy of
contact with the public on many levels.”
“Now, we have a rather advanced dialogue with Rosatom structures,” Nikitin said.
Drastic reduction in planned nuclear power plants
Among the more surprising developments was Rosatom head Sergei
Kiriyeko’s announcement to the some 1,000 participants gathered from 18
different nations at the international conference that the state nuclear
corporation would be abandoning its zealous 2008 “roadmap” to construct
some 35 new nuclear power reactors.
Instead, Kiriyenko told the delegates that a new roadmap had been
developed for 2013 to 2024 that involved building only 18 new nuclear
reactors, none of them floating.
