Your report (December 30) on the closure of Wales’ last nuclear power plant, at Wylfa on Anglesey, marks an important moment in Welsh industrial history. (“Wylfa nuclear power station marks its final day after more than 40 years in service” (http://www.walesonline.co.uk/news/wales-news/wylfa-nuclear-power-station-marks-10665028
Wylfa Site Director, Stuart Law, is reported in Heledd Pritchard’s article
as saying the closure marks a “safe and dignified end to the generation of
electricity at Wylfa” and that the main focus for the coming months is to
prepare staff and the site for defuelling the Magnox reactors, originally
ordered by the now defunct nationalised power generator, the Central
Electricity Generating Board (CEGB) in the late 1960s.
But the account of the 44 years’ operating life of the reactor omits one
very important aspect: the production of plutonium for use in nuclear warheads,
both in Britain and the US.
This was first revealed in an exclusive front page Western Mail story by your then political editor, Sarah Neville, on
8 October 1984. It was followed in more detail by former Labour MP for Blaenau
Gwent, Llew Smith - for whom I used to do research - on in a feature article in
the Western Mail on 3 March 1986,
followed up by a letter in the paper from Mr Smith (“Safety problems at Wylfa Nuclear plant, “11
December 1995).
Mr Smith cited an interview I conducted on 19 January 1983 with the late
Lord Hinton, the first chairman of the CEGB, (barely five months before his
death, at which point he was still advising the electricity industry) in which
he said to me “Wylfa is a long and sad story. It ought not have been built at
all, but when I suggested this to the Permanent Secretary [at what is now the
Department of Energy and Climate
Change] he said you have got to build it
in order to meet the government programme.”
The programme to which Lord Hinton referred was not electricity generation
but plutonium production, as became clear in the Sizewell B nuclear plant
public inquiry which had just begun when
I interviewed Lord Hinton, and ran for 333 days.
During that inquiry, Professor Keith Barnham , who with myself gave expert evidence for the CND Sizewell
Working Group, produced technical evidence demonstrating around 630 kilogrammes (+ or – 80 kgs) of plutonium
produced in UK magnox reactors had been exported to the US for military use ( a
nuclear warhead c typically uses 5-10 kilos). This research was published in
detail in the prestigious international science weekly journal, Nature,
on 19 September 1985.
A decade later, in October 1995, former Labour peer,
the late Lord Hugh Jenkins of Putney, a life-long CND supporter, asked the
Government in a written Parliamentary question (headed, Wylfa Power Station: Plutonium Creation109WA ) ‘how much plutonium Wylfa nuclear
power station has created since it began operation in 1971, where it has gone
and where it is now, and what relationship there is at the plant between
plutonium production and the generation of electricity.
Lord
Fraser of Carmyllie, answering for the Conservative Government
said: “Since 1986/87, estimates of the plutonium contained in the reactor
discharges at Wylfa power station have been published as part of the annual
plutonium figures. I cannot answer for previous Administrations. Amounts
arising from Wylfa continue to contribute to the United Kingdom's civil
holdings under international safeguards…Irradiated fuel from Britain's various
civil Magnox reactors is reprocessed together and therefore the plutonium
arising, whether in store or exported, is not linked to the specific power
station in which it was created.” [House of Lords 23 October 1995, column 109WA
109WA]
The
give-away is the minister’s admission that nuclear fuel from all Magnox
reactors was “processed together” (at Sellafield) and hence the recovered plutonium loses
it identity.
The
export of UK plutonium to the US took place under a controversial 1958 bilateral
UK-US deal, called the Mutual Defense Agreement on Atomic energy matters
( as amended in 1959) The word defence is spelled with an ‘s’ even in the
British edition, giving away the origin of its drafters in the US!)
When
this draft agreement was discussed in the US Congress on 4 February 1958 (it was never debate in
the British Parliament at all before coming into force) Lewis Stauss, chairman of the US Atomic Energy Commission, let slip the following nuclear nugget of
information on the aim of the deal with the UK “This is primarily to supply
plutonium to us for our unrestricted use, which is to say , at present,
our military use.”
This UK-US MDA was most recently renewed in October 2014,( http://www.acronym.org.uk/articles-and-analyses/government-release-amendment-agreement-2014-mutual-defence-agreement
) and despite being challenged by the then Labour back bench MP Jeremy
Corbyn, in a Parliamentary debate on 6 November 2014 (www.publications.parliament.uk/pa/cm201415/cmhansrd/cm141106/halltext/141106h0001.htm)
, remains in force.
So when Wylfa’s final discharge of spent nuclear fuel is finally
reprocessed at Sellafield, the plutonium could still end up in US nuclear
warheads
We should not be complacent about this .
