Medtronic and Alcatel developed a plutonium-powered pacemaker, the Numec NU-5, powered by a 2.5 Ci slug of plutonium 238, first implanted in a human patient in 1970. The 139 Numec NU-5 nuclear pacemakers implanted in the 1970s are expected to never need replacing, an advantage over non-nuclear pacemakers, which require surgical replacement of ...
The battery is a betavoltaic cell using carbon-14 (14 C) in the form of diamond-like carbon (DLC) as the beta radiation source, and additional normal-carbon DLC to make the necessary semiconductor junction and encapsulate the carbon-14.
By 1986, the estimated cost had blown out to $3.8 billion (equivalent to $9 billion in 2023) and the reactor was still unfinished. Meanwhile, the estimated total cost of the entire project had increased from $4.1 billion in 1973 (equivalent to $10 billion in 2023) to $24 billion in 1986 (equivalent to $57 billion in 2023).
Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
More than a year after California endorsed a proposal to extend the lifespan of its last nuclear power plant, disputes continue to swirl about the safety of its decades-old reactors, whether more ...
In 2017, the Congressional Budget Office produced a report analysing the planned expenditure and its estimate of the total cost over 30 years was $1.2 trillion. This was before any additional capacity which might result from the Nuclear Posture Review of the Trump administration, which was expected to be completed in early 2018.
Doubling the price of uranium would add about 10% to the cost of electricity produced in existing nuclear plants, and about half that much to the cost of electricity in future power plants. [53] The cost of raw uranium contributes about $0.0015/kWh to the cost of nuclear electricity, while in breeder reactors the uranium cost falls to $0.000015 ...
The MC3656 Main Battery is identical to the battery used on the B61-7 and is thermally operated, providing 120 seconds of power for the weapon, [36] but initial power is supplied by the MC2238 Pulse Batteries which are activated by the weapon's pullout switches during separation from the aircraft.
