Bill Gates: Stop shutting down nuclear reactors and build new nuclear power
plants to fight climate change

As some nuclear power companies continue to shut down nuclear reactors for
reasons ranging from economic woes to safety concerns, Bill Gates is bullish
on nuclear power as a clean energy solution to climate change.

Gates, who is also an investor in nuclear power, told the Nuclear Energy
Institute’s Nuclear Energy Assembly on Wednesday that the United States
needs to strengthen its commitment to existing nuclear power plants and
invest in new ones.

“Today, nuclear power is at a crossroads. Nearly 20% of America’s
electricity comes from nuclear,” Gates said. “But while America’s current
nuclear capacity serves the country well, there are far more reactors slated
for retirement than there are new reactors under construction.”

In April, the Indian Point Energy Center nuclear power plant north of New
York City retired its last operating nuclear reactor. And the Exelon
Corporation has announced plans to retire two of its Illinois nuclear power
plants in the fall.

If these retirements come to fruition, 2021 could set a record for the most
retirements of nuclear generators in a year, according to the U.S. Energy
Information Administration (EIA). Since 1960, the United States has retired
40 nuclear generators but it has never this many in one year, sasy an EIA
spokesperson.

According to Gates, “if we’re serious about solving climate change, and
quite frankly we have to be, the first thing we should do is keep safe
reactors operating.”

But “even then, just maintaining that status quo is not enough. We need more
nuclear power to zero out emissions in America and to prevent a climate
disaster,” Gates said Wednesday.

(Getting to “net zero” emissions means achieving no new quantity of
emissions in the atmosphere, according to the United Nations, both through
reduced emissions and removal of emmissions from the atmosphere.)

Gates is the founder and chairman of TerraPower, an advanced nuclear
technology company that launched in 2006. On June 2, TerraPower announced it
will build an advanced nuclear power plant at a retiring coal power plant in
Wyoming. The specific location in Wyoming is not yet decided: several
potential locations in Wyoming are under currently under consideration,
according to the company.


Gates said Wednesday that TerraPower will use the coal plant’s existing
infrastructure and its skilled workforce to build and operate the advanced
reactor plant, which is called Natrium. TerraPower developed the Natrium
technology in collaboration with GE Hitachi Nuclear Energy.

“We hope to show that on top of all of its energy benefits, advanced nuclear
can play a key role in the development of good jobs for skilled workers
across the country,” Gates said.

Other companies, like the Rockville, Md.-headquartered X-energy, are also
building advanced nuclear reactors.

In October, the U.S. Department of Energy (DOE) announced it is investing $80
million in TerraPower and X-energy, for a total of $160 million. Rita
Baranwal, then the Assistant Secretary for nuclear energy, said at the time
that the urgent development of nuclear technology is “important not only to
our economy, but to our environment....” (Baranwal is now the chief nuclear
officer at the Electric Power Research Institute, a global research and
development energy organization.)

Though Gates “strongly” believes “nuclear power must play a role in
getting the world to net zero,” and that everyone from technologists to
utility companies must have “a common vision for the role of nuclear in our
electric grid,” other experts disagree.

For instance, in February, academics and other researchers signed a public
declaration calling for fighting climate change by transitioning to 100%
renewable energy from sources including wind, solar, hydropower, geothermal,
tidal and wave energy.

Nuclear energy is not considered renewable, says Stanford University
professor Mark Z. Jacobson, one of the signatories of the declaration.
Nuclear fission, the process currently used to create usable nuclear energy,
requires uranium as a fuel, which is a finite resource, he says.


Jacobson says that, in fact, “investing in new nuclear power is the surest
way to climate disaster.” Climate change is urgent, and new nuclear power
plants are expensive and take a long time to build, he says.

Jacobson, who has published a textbook on renewable energy, also points out
that nuclear power comes with concerns that renewables don’t have, including
weapons proliferation, meltdowns, radioactive waste and uranium mining risks.

“New nuclear is basically an opportunity cost,” he says.
