Sometimes other signs and symptoms precede sudden cardiac arrest. These may include fatigue, fainting, blackouts, dizziness, chest pain, shortness of breath, weakness, palpitations or vomiting. But sudden cardiac arrest often occurs with no warning.
In the core of nuclear reactors, the fission of uranium atoms releases energy that heats water to about 520 degrees Farenheit. This hot water is then used to spin turbines that are connected to generators, producing electricity.
This is the principle behind nuclear reactors that produce power and generate electricity. Controlled Nuclear fission is used in nuclear reactors and harnessed for electricity where uncontrolled nuclear fission is used for war and nuclear weapons.his is the principle behind nuclear reactors that produce power and generate electricity.
