Nuclear power plants use the heat produced during nuclear fission to heat water. Steam generators are heat exchangers used to convert water into steam from heat produced in a nuclear reactor core. Thermal Insulation for Nuclear Power Plants and Nuclear Safety Issue Tritium is one of the least dangerous radioisotopes because it emits very weak radiation and leaves the body relatively quickly. Nuclear power plants conduct both controlled and uncontrolled releases of radiation. The majority of coal combustion wastes are fly ash. Steam generators are heat exchangers used to convert feedwater into steam from heat produced in a nuclear reactor core. The steam loops are separate; anything that is in contact with nuclear materials stays in the system, is condensed and reused. Yet, despite the media hysteria, not one person at the nuclear plant died because of radiation leaks. Tritiu. The potential for such devastation lies in the radioactive fuel that fires the nuclear power plant. Water also was used to cool spent fuel rods inside a large pool. According to a study of Brazilian Professor Anselmo Salks Paschoa, nuclear power plants have been known to release radioactive elements through their piping systems, seals, steam valves or pressurizers too.
