WebWatch on. Once a nuclear bomb has been launched, it is extremely difficult to stop it, if not impossible. The moment the bomb is launched, it begins to pick up speed and reach high altitude, making it impossible to intercept or stop. Even if a missile interceptor system or anti-ballistic missile is in place, it might not be able to stop a ... WebIn a typical shutdown, regular levels of coolant are still required, and the fuel remains reasonably hot, as it continues to react. In a cold shutdown, the coolant system is typically lowered to pump water at atmospheric pressure, and the reactor vessel remains below 93 °C (200 °F), and water passing through it will not boil.
