The ‘shale gas revolution’ is

dimming revival prospects for

the nuclear power industry in the

United States

Not much notice has been taken of the dampening effect

that the cheaper natural gas made possible by the fracking

method is having on American nuclear power companies. But

industry experts consulted by the

Detroit Free Press

say that

today’s low natural gas prices, together with slower growth in

demand for electricity and recent expansions in renewable

energy generation, make it less appealing to build new

nuclear plants – or even to keep older plants running if they

need expensive repairs.

Free Press

business desk reporter JC Reindl recently

presented a case in point: Fermi 3, Michigan’s first new

nuclear power reactor in more than a quarter of a century,

now close to gaining a combined construction and operating

licence from federal regulators. But according to Mr Reindl

it is an open question whether the plant will ever be built.

(“

Cheaper Natural Gas Prices Could Shelve Plans for Fermi

3

,” 23 February)

Fermi 3 would neighbour DTE Energy’s currently operating

Fermi 2 nuclear plant on Lake Erie about 30 miles south

of Detroit. It also adjoins the former site of Fermi 1, an

old experimental reactor which experienced an emergency

shutdown in 1966. DTE has been seeking permission for

Fermi 3 since September 2008.

Local anti-nuclear groups fervently opposed to Fermi 3 would

like to see the $10 billion estimated cost of the project go

instead toward wind turbines, solar panels and other low-

carbon energy systems. But it is the fading financial allure of

nuclear power that will deliver even short-term victory to the

opposition.

As noted by Mr Reindl, financial reasons were cited in the

shutdown ahead of schedule of four nuclear power plants – in

California, Florida, Vermont and Wisconsin – over the past

two years. He wrote, “Back when DTE proposed its new Fermi

reactor, the energy market had not yet been reshaped by the

shale gas revolution.”

Michiganders, like Americans in general, are using less

electricity, which means less demand for the power sold

by utilities. Energy Information Administration (EIA) data

shows that total power use in the US declined nearly 1 per cent

between 2008 and 2013. In Michigan, over the same period,

electricity sales fell 2.5 per cent as wind turbines, solar panels

and biomass generation sites proliferated across the state.

Michigan has mandated that utilities generate 10 per cent of

their electric sales by 2015 from renewable energy sources.

DTE Energy, the owner of Fermi 3, says it will reach that mark.

Also, later this year the federal Environmental Protection

Agency (EPA) could finalise rules to cut carbon dioxide

emissions from plants by 30 per cent from 2005 levels by

2030. But Jeremiah Johnson, assistant professor at the

University of Michigan’s School of Natural Resources &

Environment, told the

Free Press

that utilities likely will not

need to resort to nuclear to meet that goal.

An irony of the uncertain prospects for nuclear power in the

US is that safety concerns, although not allayed altogether,

would seem to have been addressed. In a section entitled

“Fermi Facts”, Mr Reindl noted that:

• Fermi 2, currently in operation near Detroit, is of similar

design to the Fukushima reactor implicated in the

meltdowns in Japan in 2011. But it has better safety

features, including backup diesel generators within a

concrete bunker situated well above the floodplain.

• Fermi 3 would be an Economic Simplified Boiling-

Water Reactor. Considered a third-generation reactor,

it is designed to be able to cool itself for a week in an

instance of complete power loss. The builder is GE-Hitachi

(Wilmington, North Carolina), a global nuclear alliance

known in Japan as Hitachi-GE Nuclear Energy, Ltd.

Automotive

A hypothesis for a lagging

industry: electric cars are losing

out to a new/old fuel-saving

technology – the turbocharger

“It’s really a mini jet engine in your car.”

Michael Stoller, a spokesman for Honeywell Transportation

Systems, was referring to the turbocharger – which Honeywell

supplies in quantity to automakers around the globe.

The forced-induction device, which reuses hot exhaust

gases to increase engine power in a smaller space,

was once the almost exclusive equipage of expensive

sports and luxury cars. But now it is turning up in vehicles

from budget subcompacts to pickup trucks and plug-in

hybrids.

As explained by Lawrence Ulrich, the chief auto critic of the

New York Times

, in turbocharger technology the hot exhaust

spins a turbine wheel at up to 250,000rpm, which compresses

air and stuffs it into engine cylinders, allowing more fuel to be

burned in a same-size engine.

An automaker is thus able to use six cylinders instead of eight,

or four instead of six, and still achieve the power of a larger

engine.

The downsized engines also best their traditional counterparts

in low-end torque, for easier acceleration. The result, Mr

Ulrich says, is 10 to 30 per cent better fuel economy, often

in conjunction with direct fuel injection, which enhances
