Kwa Tanzania naamini kabisa Tunaweza tukapata Nishati kwa Bei nafuu bila Kuhitahi matumizi ya Nishati ya Hatari kama Nuclear.
Lakini Nuclear Power / Energy ina nguvu sana na ikitumiwa inaweza kusaidia Suala la Nishati kwa Dunia, lakini hatari yake kwa mustakabari wa dunia ni kubwa sana, Sasa swali kama sisi hatutumii na wengine wanatumia ambayo ni hatari kwa wote je wanaotumia watulipe sisi kwa kutuletea hatari au na sisi tutumie ili tuendelee kuwekana kwenye hatari... Ifuatayo ni Extract kutoka BBC kuhusu the maybe comeback ya Nuclear

Is nuclear power gaining new energy?
A decade ago, it seemed as though the global nuclear industry was in an irreversible decline.
Concerns over safety, cost, and what to do with radioactive waste had sapped enthusiasm for a technology once seen as a revolutionary source of abundant cheap energy.
Yet now there is widespread talk of a revival, fuelled by tech giants Microsoft, Google and Amazon all announcing investments in the sector, as well as the growing pressures on wealthy nations to curb their carbon emissions.
But how real is the comeback?
When commercial nuclear power was first developed in the 1950s and 1960s, governments were seduced by its seemingly unlimited potential.
Nuclear reactors could harness and control the same awesome forces released by atomic bombs - to provide electricity for millions of homes. With a single kilogram of uranium yielding some 20,000 times as much energy as a kilogram of coal, it seemed like the future.
But the technology also inspired public fear. And that fear seemed to be justified by the Chernobyl disaster, which spread radioactive contamination across Europe in early 1986.
It fuelled widespread public and political opposition – and slowed the growth of the industry.
Another accident, at the Fukushima Daichi plant in Japan in 2011, re-energised concerns about nuclear safety. Japan itself shut down all of its reactors in the immediate aftermath, and only 12 have since restarted.
Germany decided to phase out nuclear power altogether. Other countries scaled back plans to invest in new power plants, or extend the lives of ageing facilities.
According to the International Atomic Energy Agency, this led to the loss of 48GW of electric power generation globally between 2011 and 2020.
But nuclear development did not stop. In China, for example, there were 13 nuclear reactors in 2011. There are now 55, with another 23 under construction.
For Beijing, scrambling to meet rapidly growing electricity demand, nuclear had, and still has, a vital role to play.
Now interest in the sector seems to be growing elsewhere once again. This is partly because developed countries are hunting for ways to meet energy demand, while striving to meet emissions reduction targets under the Paris Agreement.
With 2024 projected to be the warmest year on record, the pressure to cut carbon emissions is mounting. A renewed focus on energy security, in the wake of Russia’s invasion of Ukraine, has also been a factor.
South Korea, for example, recently scrapped plans to phase out its large fleet of nuclear power stations over the next four decades – and will build more instead.
And France has reversed plans to reduce its own reliance on nuclear energy, which provides 70% of its electricity. Instead, it wants to build up to eight new reactors.
In addition, last week the US government reaffirmed at the United Nations Climate Change Conference, or Cop29, held in Azerbaijan, that it intends to triple nuclear power generation by 2050.
The White House had originally pledged to do this on the side lines of last year's conference, Cop28. A total of 31 countries have now agreed to try to triple their use of nuclear power by 2050, including the UK, France and Japan.
Also at Cop29, which ends on Friday, 22 November, the US and UK announced that they would collaborate to speed up the development of new nuclear power technology.
This follows after it was agreed in the final statement or “stocktake” of last year's Cop28 that nuclear should be one of the zero or low emission technologies to be “accelerated” to help combat climate change.
