FLYING IN FORMATION: PRICE -
ANDERSON AND THE COMMERCIAL NUCLEAR POWER
INDUSTRY
The
insurance industry makes fortunes by “thinking the unthinkable:” calculating a
price for betting that catastrophic events will not happen, but just in case
providing means for financial recovery. Realizing that the potential risks and
damages from a nuclear power accident were beyond the ability of the private
insurance industry to cover, Congress in 1957 created the Price-Anderson Act as
an amendment to the Atomic Energy Act, to provide liability coverage. Amended
several times, most recently in 1988, the statue covers both military
contractors and civilian nuclear power and provides the basis for exclusionary
clauses in other US property and liability policies, which preclude recovery for
damages from nuclear releases, accidents, and nuclear war.
The
provisions that create liability coverage for nuclear power are interesting:
essentially the industry is yoked at the neck--all will pay if any one has a
major accident.
First, reactor owners pay
into a self-insurance pool of $200 million, designed to cover events that fall
short of a Chernobyl-style disaster. A second pool of about $8 billion would be
composed of fees levied to every operating reactor in the US, to be triggered by
an accident that exceeds the first pool. Each reactor–there are 103 operating
today–would pay a share prorated from the total, up to $79 million each ($75
million plus a 5% insurance surcharge), paid over a 7-year period--or $10+
million per reactor, per year. The liability of the nuclear industry for that
accident is then capped.
Thus ~ $8 billion is the
maximum financial “contribution” the commercial nuclear industry would make in the event of
nuclear catastrophe. Beyond the cap, taxpayers would pick up the tab in the form
of disaster relief funds, and /or affected individuals–victims– would absorb the
real costs.
Eight billion dollars is a
“fine chunk of change,” however some estimates have placed the costs of
Chernobyl above $350 billion to date. Sandia National Lab in 1982[2]
projected that a major accident at the Indian Point reactors on the Hudson River
near Manhattan would exceed $300 billion (1982 dollars). Taxpayer exposure to
nuclear liability under Price Anderson is significant, and shows $8 billion to
be what it is: a small contribution.
BREAKING
FORMATION: DUKE POWER AND WEAPONS-PLUTONIUM
Since Price-Anderson links
all U.S. nuclear power reactors to take (limited) liability for an accident at
any one site, the assumption is that the operation of each of these reactors
contributes a comparable level of risk to the overall chances of an accident
occurring. In 2000, one utility, Duke Power crossed over a line that breaks
these assumptions: the decision to use experimental fuel made from nuclear
weapons derived plutonium, called MOX.
EXPERIMENTAL
FUEL INCREASES NUCLEAR LIABILITY
MOX--Mixed oxide (plutonium
and uranium) fuel is known, by its limited use in Europe, to challenge nuclear reactor
operation, and is therefore more costly to produce and use than uranium fuel.[3]
European MOX fuel is made from plutonium from commercial reactor waste. Nowhere
in the world has weapons-grade plutonium been used to power a commercial
reactor, let alone plutonium extracted from a nuclear warhead. The key here is
not only the higher concentration of plutonium-239 which is good for bombs, and
never tested in reactors, but also the fact that many other ingredients were
added to the plutonium to make warhead “pits” that were never intended to go
inside a nuclear reactor.
Duke is slated to begin use
of weapons-grade plutonium MOX fuel in four nuclear reactors in the Carolinas
under a contract with the US Department of Energy, part of a US–Russia agreement
on surplus plutonium. For many reasons, a large alliance of public interest
groups oppose the use of weapons-plutonium as MOX fuel, not the least of which
is reactor safety concerns.
Two
key physical characteristics of uranium[4]
give reactor operators some natural advantage in control of the fission process.
1) The presence of “delayed neutrons” allows operators to use control rods to
slow and stop the reaction. Weapons-grade plutonium has only 1/3 as many
“delayed neutrons,” reducing the effectiveness of control rods. 2) Uranium is
more difficult to split as the temperature goes up, whereas heat makes it easier
to split plutonium. These factors further reduce the margin of safety on aging
reactor operations.
Plutonium also delivers more
hard, fast neutrons, which age and fatigue reactor components more than
conventional fuels. Additionally, one of the elements added to plutonium to make
bombs, gallium, attacks the metals used to make fuel rods. These concerns
contribute to an increased risk of reactor accidents with MOX
use.
The Department of Energy has
validated findings by Dr. Edwin Lyman of Nuclear Control Institute[5],
that if there is a major reactor accident with MOX fuel in use, the health
consequences will be far greater than from a similar accident in a
conventionally-fueled reactor. Dr. Lyman’s findings show that if 100% MOX fuel
is in use, the number of cancers and cancer deaths would double compared to the damage uranium
fuel would cause. The function is linear, so initial plans to use 1/3 MOX fuel
would result in about 30% more deaths. NRC approval of this program is pending.
It is not clear why any federal agency would approve or proceed with a plan that
so drastically increases health risks, nor is it clear that Price-Anderson
should cover Duke’s increased liability.
DUKE: AN EXCEPTIONAL RISK ANYWAY
Of
103 reactors in the US, Duke’s McGuire-1 & -2 and Catawba-1 & -2 have
the lowest level of protective containment in the US. A recent NRC report shows
the potential for a major reactor accident combined with loss of containment at
these sites. Duke and DOE have made an extremely risky decision to use
experimental fuel.
PRICE-ANDERSON DUMPS PLUTONIUM LIABILITY ON TAXPAYERS
Price–Anderson, as written
today, caps the nuclear industry’s liability for a major accident with uranium
fuel, at a fraction of projected costs. It is a case of pouring water on a full
cup: all additional accident costs due to MOX fuel would fall on the public--Mary Olson[6],
