On the way to medically usable nuclear batteries Russian researchers have achieved a major technological progress.

It was, a possible source of energy, the radioactive isotope Nickel-63, in a gas centrifuge to more than 69 per cent enrich. The state Russian manufacturer of nuclear fuel, informed materials of JSC “TVEL” in Moscow. The degree of enrichment of the life of the battery depends. Even in 2019, to be achieved in the research plant in Zelenogorsk in Siberia, an enrichment of about 80 percent.

According to TVEL compact nuclear batteries with a lifespan of up to 50 years, currently in Trend in instrument making and radio electronics.

the nuclear-powered micro-batteries are suitable where a tiny energy sources must operate over a long time maintenance-free. As areas of application, the Rosatom subsidiary of the world called space-, military – or industrial plants. But also “heart pacemakers and other biostimulators” could be supplied from these nuclear batteries. For comparison: The manufacturer Medtronic on its website that the batteries of his heart to keep a pacemaker for about five to ten years – depending on how often the device needs to be active.

The power, not nuclear mini batteries, such as in the nuclear power plant as a result of the energy development nuclear fission, but rather from the natural decay of man-made radioisotopes such as Nickel-63 or Tritium. In such batteries, research groups working in several countries, informed the Federal office for radiation protection (BfS) in Salzgitter to dpa request. “This type of direct electricity generation from radioactive decay is known as beta-voltaic.”

the Nickel with the element symbol Ni is a metal. The artificially produced isotope Ni-63 has a half-life of 100 years. It was divided into a “soft Beta radiation without the use of harmful Gamma radiation,” said TVEL. In order for the use of the medicine in question. To Shield this radiation in a simple plastic packaging rich “already,” said a BfS spokesperson.

New to the idea of nuclear-powered pacemaker is not. The mid-1970s, several patients in the US, but in Germany, too, had been planted batteries with the isotope Promethium-147, said the BfS. It did, however, problems of size, lifespan and shielding against radiation.

The US space Agency Nasa has long been used as nuclear batteries – so-called RTGs (Radioiosotope Thermoelectric generator) as a source of energy for plants in space. Most of the time, a very strong alpha emitter Plutonium-238 is used. The Soviet Union provided earlier also lighthouses and other remote systems with RTGs.
