The award-winning blockchain method to improve global security

The Geneva Centre for Security Policy (GCSP) awarded the SLAFKA application third prize in the Innovation in Global Security category. A total of 113 innovations from different countries participated in the competition.

SLAFKA ensures the reliability of nuclear material data

Posiva, which takes care of the spent nuclear fuel final disposal of TVO’s and Fortum’s nuclear power plants, is constructing the world’s first spent nuclear fuel final disposal facility in Finland.

Once the spent nuclear fuel is disposed of by placing it deep inside the bedrock, it can no longer be inspected on-site. However, the information concerning the disposed nuclear material must be reliably retained.

The SLAFKA application, developed by the Radiation and Nuclear Safety Authority together with the Henry L. Stimson Center and the University of New South Wales, is based on the blockchain technology and developed to improve the reliability of the nuclear material records.

“For us, it is important that the data generated during the disposal process can be retained in an unchanged format for thousands of years,” says Elina Martikka, Head of International Cooperation at the Radiation and Nuclear Safety Authority. ”The data generated for the safeguards of nuclear materials provides certainty that Finland is fulfilling its obligations pursuant to the Treaty on the Non-Proliferation of Nuclear Weapons.”

According to Elina Martikka, this award proves that the development of security-related innovations is a current and important issue, even on a global scale.
