Cleaning Water with Nuclear

It’s a startling fact: In just 10 years, our growing population and rising industrial development will mean that almost a third of the world will not have access to clean water.

Almost all the world’s water—96 percent of it—exists in oceans that contain salt. But humans need fresh water, and “fresh” means water that contains fewer than 1,000 parts per million dissolved salts in one percent of its weight. Ocean water contains almost 35,000ppm.

Desalination removes salt from water using heat – lots of heat. If the heat comes from fossil-fuel sources, then desalination contributes to climate change. That’s because all fossil fuels—oil, gas or coal—release greenhouse gases into the atmosphere.

The need for clean and accessible water cannot be overstated. A recent alarming WHO report found that one in three people are affected by water scarcity. A number that would be higher had it not been for desalination plants. Almost a quarter of a billion people rely on desalination to supply them with clean water. Desalination plants supply Israel with almost half of its water, Japan holds a fleet of 10 desalination facilities which provide electricity and potable water.

Nuclear power plants look interesting to countries with a fresh-water shortage due to environmental benefits. According to Dr. Ibrahim Khamis, a senior nuclear engineer with the IAEA, “A nuclear power plant is like any heat source. The moment you use the reactor, the cost of fuel is much less and it has a lot of energy.”

Nuclear plants produce tremendous heat which drives steam turbines to make electricity. They can use leftover heat to boil ocean water. When steam condenses, it becomes pure, clean water; the salt drops out and can be returned to the ocean.

Dr. Khamis says using nuclear power to desalinate water has both economic and environmental benefits, combining two projects into one. “Instead of having a desalination plant somewhere and a power plant somewhere else and each one has intake, withdrawing the water, you can bring them together to improve the environmental impact and become more green when you use nuclear desalination,” he says.

According to the World Nuclear Association,The feasibility of integrated nuclear desalination plants has been proven with over 150 reactor-years of experience, chiefly in Kazakhstan, India and Japan.”

After decades of research, India launched a hybrid Nuclear Desalination Demonstration Project, the largest of its kind.

Using nuclear technology to provide safe, clean drinking water is nothing new. The U.S. Military has relied on nuclear reactors to provide potable water to submarine and aircraft carrier personnel.

With the global demand for water on the rise, nuclear technology could be a solution to the world’s fresh water supply, providing security and prosperity to countries in need of fresh water. Nuclear technology could prove to be a solution when faced with a dwindling fresh water supply. Providing security, prosperity and growth to countries starved for access to water.

Talking Climate Change at WiN Global

By Heather Kleb
President
WiN Canada

In late August 2015, I had the pleasure of joining more than 400 Women in Nuclear (WiN)–Global members, from over 60 countries, at our annual conference in Vienna, Austria. Hosted by WiN–IAEA at the offices of the United Nations, the conference featured sessions on: medical use of radiation, safeguards and non-proliferation, nuclear security, and energy, environment and climate change.

One of the highlights of the conference was a climate-change panel with representatives from six countries. Among them was the Director General of the World Nuclear Association, Agneta Rising. Ms. Rising reminded participants of how quickly nuclear ramped up in the 70’s and that only one country (Germany) is now phasing out nuclear. This important context needs to be included in any discussion of the future of nuclear, and its role in mitigating climate change.

Climate change was also the focus of discussions during the WiN–Global board and executive meetings, where board members agreed to call for member support of a “Declaration of Nuclear for Climate.” The Declaration, which builds on the May 2015 agreement signed by 39 nuclear associations and 50,000 scientists from 36 countries, supports Nuclear for Climate’s global initiative to recognize the contribution of nuclear as a solution to climate change.

The WiN–Global declaration further reinforced that any discussion of low-carbon solutions that excludes nuclear is incomplete. Members of WiN-Canada were among the signatories to the Declaration, which requested that the “UNFCCC (United Nations Framework Convention on Climate Change) Protocols recognize nuclear energy as a low-carbon energy option, and that it be included in its climate funding mechanisms, as is the case for all low-carbon energy sources.”
