AS NEW EVIDENCE COMES TO LIGHT ABOUT FAULTY NUCLEAR FACILITY VENTILATION FILTERS…..
MEDIA STATEMENT: 2 April 2009
Is the unabated greed associated with South Africa’s scandalous Pebble Bed Modular Reactor (PBMR) nuclear experiment the real reason for Pretoria’s “disgraceful” decision to withhold a visa from the Dalai Lama, the anti-nuclear Pelindaba Working Group asked in a statement today?
Having failed after 10 years of taxpayer funding – and now 10 times over budget – to produce a safe PBMR to generate electricity in South Africa, the PBMR Company has now teamed up with their Chinese nuclear counterparts to cause great international embarrassment merely to foist its nuclear agenda on this country rather than scrapping the project.
The ink on this nuclear agreement is barely dry yet nuclear authorities are trying to push through amendments to the Record of Decision (RoD) on the new scaled-up PBMR nuclear fuel factory at Pelindaba seeking an “exemption” from an environmental impact study for a radioactive waste incinerator to “reprocess” spent fuel. This, in spite of there being no final design or safety approval for the PBMRs failed technology.
It seems our nuclear industry have no scruples and will stop at nothing.
Lengthy documents submitted to the Environment Minister on the RoD amendment yesterday provided new evidence that High-Efficiency Particulate Air filters, commonly known as HEPA filters, to be used in the fuel plant have inherent vulnerabilities that are potentially catastrophic.
In declarations currently before a U.S. District Court in Northern California, evidence of veteran U.S. nuclear scientist Marian M. Fulk states HEPA filters won’t protect public health or workers.
Fulk says in his declarations authorities have relied “on unduly optimistic assertions about HEPA filters” derived from an internal lab report that has never been made publicly available and is now “missing from the Administrative Record”.
“There is a wealth of peer-reviewed, credible and publicly-available expert data on the efficiencies of and problems associated with HEPA filters. Therefore, the omission of this information and any detailed analysis of HEPA filter deficiencies…is both baffling and inexcusable,” Fulk says in his declaration under oath.
HEPA filters are all that stands between the radioactive materials inside many a nuclear installation and the surroundings outside of these facilities and is the best the world has to offer. Yet the risk inherent in the vulnerabilities of HEPA filters is potentially catastrophic, even under “best operating conditions”, says Fulk.
They are fitted in the ventilation applications of every one of South Africa’s nuclear facilities, existing and proposed – including Koeberg and Pelindaba.
At which point will authorities in this country say we’ve had enough secretive manipulation from the nuclear industry agenda? Or are the vested interests for some worthy of the huge risks involved, including a snub of the Tibetan spiritual leader the Tibetan government in exile blames on “intense pressure” from China?

PLEASE NOTE: Fulk’s declarations can be forwarded to those who are interested. In them, this is how he describes his right to a view on HEPA filters:
“I am a Chemical Physicist, retired from the University of California, Lawrence Livermore National Laboratory in 1984, where I served 18 years as a staff scientist in chemical physics and material sciences. At LLNL most of my work was classified, but it included the study of radioactive rainout and aerosols; their dynamics, initiation and growth. At LLNL, I studied problems associated with aerosolized particles and their capture by High Efficiency Particulate Air filters, commonly called HEPA filters. I also studied various toxic and radioactive materials including uranium and plutonium. I have worked professionally on these issues for the University of California and the Department of Energy (DOE) and its predecessor agencies, including the Atomic Energy Commission, since my work at the University of Chicago where I conducted research on biological systems beginning in 1945.”
SA, China PBMR projects to cooperate By: Keith Campbell
Published: 30 Mar 09 South Africa’s Pebble Bed Modular Reactor (PBMR) company has signed a Memorandum of Understanding (MoU) with its Chinese counterparts, the Institute of Nuclear and New Energy Technology (INET) of Tsinghua University and the Chinergy company. INET and Chinergy are also developing PBMR technology.
The MoU is intended to encourage cooperation in specific areas of common interest, both strategic and technical, concerning both countries’ PBMR projects, to create opportunities regarding the commercialisation of the technology in the future, and to reinforce the supply chains in both countries.
PBMR technology was originaly developed in Germany and subsequently licensed to both South Africa and China, each country further developing the concept, although in somewhat (but not fundamentally) different directions.
The Chinese, unlike the South Africans, actually have an operational PBMR reactor, although it is only a small – 10 MW (thermal) – research unit. Located at INET in Beijing, it is the only operational PBMR in the world, and was started in December 2000, achieving full power in January 2003.
The main difference between the two PBMR projects is that the Chinese will use an indirect cycle, steam turbine system for their commercial-scale demonstration plant, while the South Africans have been developing a direct cycle, gas turbine system.
The Chinese demonstration plant will comprise two 250 MW (thermal) reactor modules and a 210 MW (electric) steam turbine generator set.
However, recently, the South Africans have started developing technology for indirect cycle, steam turbine systems, as a result of increasing interest in process heat and co-generation applications for the PBMR.
This means that the South African programme is now converging with the Chinese, creating more synergies between them. This became very clear at an international high temperature reactor (HTR) conference in Washington, DC, in December.
This was followed, earlier this year, by a visit to South Africa by representatives of INET and Chinergy, who, with their local counterparts, worked out the framework for cooperation.
The PBMR is an HTR design and is so named because its fuel is in the form of spheres. These take the form of enriched uranium oxide coated with silicon carbide and pyrolytic carbon, in turn encased by graphite. The resulting sphere is about the size of a billiard ball.
A fully-loaded PBMR reactor core would contain some 450 000 fuel spheres. Because of its design and and the nature of its fuel, it will be possible to remove spent fuel spheres from the bottom of the PBMR, and feed fresh fuel spheres in at the top, while the reactor is running.
In other designs, the reactor has to be shut down for refuelling to take place.Copyright Creamer Media (Pty) Ltd. All rights reserved.
Dalai Lama’s South Africa conference ban causes uproar
By Chris McGreal in Johannesburg guardian.co.uk, Monday 23 March 2009 18.33 GMT Two of South Africa’s Nobel peace prize winners, Archbishop Desmond Tutu and FW de Klerk, have pulled out of a Johannesburg conference to fight racism after what they branded as Pretoria’s “disgraceful” decision to ban the Dalai Lama from attending following Chinese pressure.The Nobel peace prize committee also said it would boycott this Friday’s conference, which is dedicated to tackling racism ahead of the 2010 World Cup.The row threatens to draw in Nelson Mandela, who, with his fellow South African laureates, invited the Tibetan spiritual leader, and further embarrasses South Africa, which has been accused of squandering its moral authority since ending apartheid by blocking UN security council moves to pressure rogue governments in Burma and Zimbabwe.Tutu, who won the prize for his resistance to white rule, told Johannesburg’s Sunday Independent newspaper he will not attend the conference to discuss how to use the World Cup preparations to combat racism and xenophobia if the Tibetan spiritual leader is not present.“If His Holiness’s visa is refused, then I won’t take part in the coming 2010 World Cup-related peace conference. I will condemn [the] government’s behaviour as disgraceful, in line with our country’s abysmal record at the United Nations security council, a total betrayal of our struggle’s history,” he said.“We are shamelessly succumbing to Chinese pressure. I feel deeply distressed and ashamed.”The FW de Klerk Foundation, established by South Africa’s last white president, said it would also pull out of the conference, albeit reluctantly.“South Africa is a sovereign constitutional democracy and should not allow other countries to dictate to it regarding who it should and should not admit to its territory,” the foundation said in a statement.“Mr De Klerk has been in touch with Archbishop Tutu and identifies himself with the views that he has expressed with regard to the refusal of the South African government to grant a visa to the Dalai Lama.”The Norwegian Nobel peace prize committee also condemned the South African decision.“It is impossible for us to be part of an event where one of the main participants is not able to enter the country,” said Geir Lundestad, the committee’s secretary.The Tibetan government in exile in India today blamed “intense pressure” from China, which has become one of South Africa’s largest trading partners. The claim was apparently confirmed by the Chinese embassy in Pretoria, where the minister counsellor, Dai Bing, was quoted as telling the South African media that his government had warned that allowing the Tibetan spiritual leader to attend the conference would damage bilateral relations.But the South African government denied its decision had anything to do with Beijing. It said the Dalai Lama had been refused a visa because his presence would draw attention away from the World Cup preparations.Thabo Masebe, the spokesman for the president, Kgalema Motlanthe, said the conference organisers had not consulted the government before inviting the Tibetan leader.“We in the South African government have not invited the Dalai Lama to visit South Africa, because it would not be in the interests of South Africa,” he said. “The attention of the world is on South Africa because of it being the host country for the 2010 World Cup, and we wouldn’t want anything to distract from that.”Pretoria has shied away from the Tibetan leader before. Ten years ago, South Africa’s then president, Thabo Mbeki, said he was too busy for a one-to-one meeting with the Dalai Lama.The actors Morgan Freeman, who is to play Mandela in a new film, and Charlize Theron, a South African, are also due to attend the conference.http://www.guardian.co.uk/world/2009/mar/23/dalai-lama-south-africa-world-cup-ban
