Abstract |
A radioisotope thermoelectric generator (RTG, RITEG) is an electrical generator that uses an array of thermo couples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect. RTGs have been used as a power sources in satellites and space probes. RTGs are usually the most desirable power source for unmaintained situations that need a few hundred watts (or less) of power for durations too long for fuel cells, batteries, or generators to provide economically and in places where solar cells are not practical. Safe use of RTGs have no moving parts and are very simple: fundamentally, they consist of a fuel cell, thermocouples and shielding. These compact, reliable systems provide basic mission fuel and keep critical spacecraft components warm enough to function in the cold, dark reaches of deep space. ISRO is about to use Nuclear Technology/Radioisotope thermoelectric generators(RTGs) to power Chandrayaan-2. The mission was planned to fly on a geosynchronous satellite launch vehicle MK-II (GSLV) with an approximate lift-off mass of 2650kg from Satish Dhawan center on Sriharikota Island. India might have been the first country to reach moon but our tricolor was the 4th national flag to be planted on the moon’s surface. Radio isotope power systems are a nuclear powered system to generate electric power to feed communication and scientific systems on a space craft. The first RTG system developed for space situation was the system for Nuclear Auxiliary power (SNAP) Keywords- Radioisotope thermoelectricgenerator (RTGs), fuel cells, thermocouples, satellites. | |||||||||
