Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

Some nuclear facilities have large tritium loads and subsequent environmental emissions and consequently, the radiological impact assessment is mandatory. In case of the unplanned (potential) accidents there are extremely large uncertainties of the model predictions for crop contamination and dose due to many factors affecting the Organically Bound Tritium (OBT) dynamics in crops. A full mechanistic model is difficult to develop due to the complexity of the processes involved in tritium transfer and the environmental conditions. The preparatory steps for a robust model are discussed in the present study, considering the role of the dry matter and photosynthesis contributing to the OBT dynamics in crops.
