Study on the Design of Passive Containment Heat Removal System
Journal of Physics: Conference Series, 2020 Abstract The containment is the last barrier to prevent the release of radioactive material into the environment after an accident. If the pressure of the containment vessel exceeds the ultimate carrying capacity of the containment, a large amount of radioactive material leaks into the external environment after the accident.

Outboard heat exchanger passive heat removal system from the reactor plant
Transactions of the Krylov State Research Centre, 2021 After the accident at the Fukushima-1 NPP, the requirements for the safety of reactor facilities became more stringent, which led to the improvement of safety systems due to the transition from active principles of operation to safety systems with passive principles. An example of such a system is a passive heat removal system (hereinafter PHRS), which
