Description

About 13% of our nationäó»s electricity is produced by pressurized water reactors that rely on lithium-7, an isotope of lithium produced and exported solely by China and Russia, for their safe operation. Lithium-7 is added to the water that cools the reactor core to prevent the cooling water from becoming acidic. Without it, the cooling wateräó»s acidity would increase the rate of corrosion of pipes and other infrastructure -- possibly causing them to fail. Utilities that operate the pressurized water reactors have experienced little difficulty obtaining lithium-7, but there are risks of relying on two producers. This report reviewed the supply and domestic demand for lithium-7 and how risks are being managed. It examines (1) what is known about the supply and demand of lithium-7; (2) what federal agencies are responsible for managing supply risks; and (3) alternative options to mitigate a potential shortage. Figure. This is a print on demand report.
