Title: A URANIUM REFINERY FOR SASKATCHEWAN


1
A URANIUM REFINERY FOR SASKATCHEWAN?

2
Our Predicament
  • Premier Calvert and Hon. Eric Cline have
    succumbed to the idea of value added for our
    uranium. They are thinking of the value-added
    jobs, wages, business, industry, money, and
    royalties.
  • They do not care about the value-added
    radiation for the workers and the people, for the
    chemicals which damage the health of people and
    despoil the environment.

3
Whats Wrong With Going Nuclear?
  • The problems have not gone away which caused the
    citizens of Warman and district to reject a
    refinery back in the 1970s.

4
Developments
  • Cameco proposed an extension of its refinery in
    Port Hope. The citizens raised so many questions
    that the proposed plans were withdrawn.

Port Hope Conversion Facility
  • Only uranium conversion facility in Canada and
    one of four in the western world
  • Only producer of uranium dioxide (UO2) for
    Canadian-made Candu reactors 2,800 tonnes per
    year of UO2
  • Produces uranium hexafluoride (UF6) shipped to
    USA for enrichment 12,500 tonnes per year
  • The only uranium conversion facility which uses a
    wet process to make uranium tetrafluoride (UF4)
    from UO2thereby reducing hydrogen fluoride (HF)
    consumption.
  • UF4 is used to manufacture depleted uranium metal
    which is used in radioactive ammunition

7
Learning from the Past
  • We need to learn from the experiences and
    discoveries of the citizens of Port Hope about
    the realities of a uranium refinery or conversion
    facility.

8
Port Hope Conversion Facility
  • A conversion facility is a huge operation to be
    placed in any of our communities.

9
A Mammoth Structure
10
Gargantuan Water Requirement
  • A refinery uses tremendous amounts of water.
    Cameco is installing a new water system for its
    Port Hope conversion facility, consisting of an
    intake pipe one metre in diameter, extending 880
    metres out into Lake Ontario, with a capacity for
    pumping 33,000 cubic metres per day! Is this one
    of the reasons for a proposal for a dam at North
    Battleford on the North Saskatchewan River?

11
  • Some 3.5 million cubic metres of low level
    radioactive waste have been deposited in the soil
    around Port Hope over many years, for which the
    authorities are now considering potential ways to
    dispose of it.

One more ounce of additional contamination added
to the 3.5 million cubic metres of contaminated
soil surrounding us would be an ounce too
much. - Farley Mowat, Member of FARE (Families
Against Radiation Exposure)
12
Yellowcake and Fuel Pellets
Yellowcake
Is in turn produced into Fuel Pellets
13
  • Large amounts of chemicals are used in the
    processing of uranium yellowcake to produce
    enriched uranium. These heavy acids used are a
    danger to the underground waters of the region
    around a refinery.

14
Dangerous Byproducts
  • The citizens of Port Hope discovered these
    byproducts of refining in their area
  • 60 kilograms a year of fine uranium dust
    dispersed in the air
  • 9.3 tonnes of ammonia used in the process
  • 113 tonnes of nitrous oxide released
  • 507 kilograms of fluoride released into the air,
    causing negative health conditions

15
A Citizens Report
  • 1. We are told it is safe to live here.
  • 2. We are told the 60 kilograms of Uranium
    emissions in 2003 were absorbed.
  • 3. We are told the 1 kilogram of Uranium in water
    emissions is very small.
  • 4. We are told the Ammonia in air released in the
    centre of our historic town and waterfront, all
    9.3 tonnes is not very harmful.
  • 5.We are told the Nitrous Oxide released into the
    air, 113 tonnes, is within MOE standards.
  • 6. We are told the Fluoride released into the air
    totals 507 kilograms.

    Port Hope, Ontario,September 28, 2004

16
Hazards of the Acids
  • In the production of hexafluoride (UF6), large
    quantities of hydrochloric acid are used which
    can cause health problems such as asthma.
  • Plus, the chlorofluorocarbon emissions (CFCs)
    destroy the ozone layer at several thousand times
    that of carbon dioxide.

17
Byproduct of the Conversion Process
  • Cameco's license permits them to produce up to
    2,000 tonnes of depleted uranium a year in the
    metals facility. Cameco will not reveal who are
    their customers. F.A.R.E

18
Malvesi, France
  • In Malvesi, France, a heavy downpour of rain
    caused some containment ponds holding large
    amounts of acid to rupture and to flow across the
    countryside, spreading thorium-234, nuclide
    americum-241 and large amounts of liquid nitrates.

Before the Storm
20
The Aftermath
21
SGI or Mobile Home Policy
  • It states that it does not cover damage caused
    by a nuclear incident as defined in the Nuclear
    Liability Act. Nor do we cover nuclear explosion
    or contamination by radioactive material.
  • SGI CANADA Policy Booklet,
  • 1168 HM -16 01/2006, Part 1, (m), p.16

22
Radiation Damage
  • Uranium mines and mill workers are still being
    exposed to radiation by alpha particles.
  • If one of the highly charged particles hits the
    delicate interior lung tissue of a worker it can
    damage the chromosomes in the cells.
  • Some 15-20 years later this damage may turn
    cancerous.
  • If a spontaneous, random particle hits the
    chromosomes, the damage is done.
  • It is not a matter of averaging the radiation
    doses to which the miners/workers are exposed.

23
New Study Regarding Radiation
  • In living lung tissue, if one of the cells
    adjacent to the particle is damaged in a certain
    way, it can become a cancer cell later on,
    spreading rapidly through the lung, causing
    almost certain death.

24
Alpha Rays From a Radioactive Particle in a Lung
Tissue
  • The black star shows the tracks made over a 48
    hour period by alpha rays emitted from a
    radioactive particle of plutonium lodged in the
    lung tissue of an ape (the particle itself is
    invisible).
  • photo by Robert Del Tredici from his book
    entitled At Work In The Fields Of The Bomb
    (Harper and Row, 1987)

25
Inadequacy of Dosimeters
  • The dosimeters, with their sensitive film, used
    to detect radiation of workers, measure the
    external bombardment of the skin.
  • However, they do not measure the number of alpha
    particles that penetrate the internal tissues of
    the lungs.

26
  • We can ignore the dangers of radiation but the
    dangers of radiation will not ignore us.

27
Radiation Risk
  • Recent findings of the 40 scientists who prepared
    the Report of the European Commission on
    Radiation Risk (2003), found that the present
    standards for radiation risk are deficient and
    dated, because they were formulated before DNA
    was discovered.
  • This Report discovered that low-dose alpha
    radiation is more dangerous than high doses (the
    Petkau Response).
  • The BEIR VII Report (Biological Effects of
    Internal Radiation) declared in 2005, that there
    are no safe levels of radiation.

28
The Present Situation
  • Mr. Donald Ching, current President of Areva
    (Cogema), has said at public meetings around the
    province that Areva would not build a conversion
    facility in any jurisdiction where it was not
    wanted.
  • We need to give him and the Premier a clear
    message now.

  • know about your concerns for
  • this project.
  • Government does not change
