A 2019 Norwegian research cruise to the sunken nuclear submarine Komsomolets has confirmed that radioactive releases from the reactor are still occurring. These releases have had little impact on the surrounding marine environment. The research cruise detected specific uranium and plutonium isotopes which suggest that the nuclear fuel assemblies have been damaged and that the nuclear fuel is in direct contact with seawater and deteriorating. Further work should be carried out to understand any corrosion processes and their implications.

Results from the 2019 Norwegian research cruise

The Norwegian government will:
- Work towards reducing radon levels in all types of building and premises to below the stated limits
- Contribute to reducing radon exposure in Norway as low as reasonably achievable.

The severe nuclear accident methodology is briefly described. The determination of radionuclide inventory in a reactor core and its release to the environment because of severe accident has been described for ACCIDENT and ORIGEN codes. The codes were applied to a hypothetical submarine accident and results were compared.

In April 2018, the U.S. Department of Energy (DOE), National Nuclear Security Administration (NNSA) Aerial Measuring System (AMS) and the Norwegian Radiation and Nuclear Safety Authority (DSA), conducted a series of joint surveys at various locations in Southern Nevada including the Nevada National Security Site (NNSS). The goal of this project was to compare the responses of the two agencies’ aerial radiation detection systems and data analysis techniques.
