Radioisotope thermo electric generators RTGs exploited the extraordinary potential of radioactive materials for generating electricity. Ppt for Nuclear Power Plant Documents. So the scientists had to find some other ways of converting nuclear energy into electric energy.
All these difficulties can be overcome up to a large extend by the use of nuclear micro batteries. To gain social acceptance. Browns first prototype power cell producedtimes as much energy per gram of strontium dynamps energy source than the most powerful thermal battery yet in existence. Any radioisotope in the form of a solid that gives off alpha or beta particles can be utilized in the nuclear battery.
The operations of both are explained below one by one.
PPT on Nuclear Microbatteries
As the charge is collected, the deflection of a cantilever beam increases until it contacts a grounded element, thus discharging the beam and causing it to return to its original position. A radio isotope electric power system was developed by inventor Paul Brown which was a scientific break through in nuclear power.
The word ‘dainty’ means pretty. Nuclear powered laptop battery Xcell-N has times more life than normal laptop batteries. This has been tested experimentally. Gamma – These are photons, just like light, except of much higher energy.
Since it is not easy to micro fabricate solid radioactive materials, a liquid source is used instead for the micro machined p-n junction battery. The mechanical stresses of the bend unbalances the charge distribution inside the piezoelectric crystal structure, producing a voltage in electrodes attached to the top and bottom of the crystal. Need for compact, reliable, light weight and long life power supplies.
Uses energy from beta particles. Published on Apr View Download 7. Batteries of the near future.

The concerned p-n junction has 13 micro machine channels and the total junction area is At that moment, electrons flow back to the source, and the electrostatic attractive force vanishes. So the self-reciprocating cantilever type nuclear batteries are also called as radioactive piezoelectric generator. One is junction type battery and the other is self-reciprocating dainyiest. Batteries should have reliability and longevity to avoid frequent replacements.

Depending on the application, these devices often require an on board power source for remote operation, especially in cases requiring for an extended period of time. The kind of nuclear batteries directly converts the high-energy particles emitted by a radioactive source into an electric current. Daintiest dynamos [nuclear microbatteries Documents. Its free end is able to move up and down. They have high energy, typically in the MeV range.
Also above this cantilever there is a piezoelectric plate. This is very important since the current generated by the powered p-n junction microbatreries proportional to the junction area. A ppt on natural disaster and safty risks at nuclear power plant Environment. NASA is trying to harness this technology in space applications.
Nuclear batteries have lifespan up to decades. Avoidance of gamma in the decay chain Half life Should be more Cost should be less. Automobiles No need for frequent recharging as in case of miceobatteries electric vehicles. The diagram of a micro machined p-n junction is shown below.
