This paper presents intermediate results in the development of a new NaK release model. A new size distribution function is introduced. The cause of the release is assigned to the procedure of the reactor core ejection. The generation of the NaK droplets is modeled as several individual events and not as a continuous leakage. In this work, an improved estimate of the mass is performed. The size distribution function is adjusted to the corrected estimate. The release events are simulated. The distribution of the droplets on orbits is evaluated. The long-term decay behavior is studied. Furthermore, the contribution of the NaK droplets to the entire space debris population is determined. The development of the model is not yet complete. It is therefore possible that the model actually implemented in MASTER-2009 may differ from this work.
