If the fuel rods became damaged they would release radioactive material into the remaining coolant.
如果燃料棒损坏，放射性物质会进到剩余的冷却剂中。
2
Once you start damaging the core, you are then releasing radioactive material into the coolant and thereby increasing the chances that something travels outside the reactor.
一旦你开始破坏核心，你就会向冷却剂中释放放射性物质，从而提高了这些物质泄露到反应堆外的危险。

Then using this method, influence of gas wall material, gas wall thickness and flow rate of coolant on regenerative cooling of thrust chamber was investigated. The results were satisfactory.
