according to the IAEAThat is more than any other country by far. Many of those reactors should be viable for some time to come, as nuclear reactors can be licensed to operate for 60 years and in some cases for as long as 80 years, theWorld Nuclear Association...
’s nuclear weapons arsenal hasn’t changed in more than a decade. Whathaschanged, however, is America’s ballistic missile defenses, which are slowly growing to include ships and interceptors based in silos. From China’s perspective, it must now have enough nukes to survive a first strike...

Nuclear power plants use heat generated in the atomic fission to generate steam and produce electrical power. The fuels for reactors are usually radioactive isotopes of uranium and plutonium. When these materials undergo fission, they break down into smaller elements and release energy and subatomic ...

Building large plants isvery costly and time-consuming. In Georgia,Southern Co.built thefirst new nuclear reactors in decades, but the project finished seven years behind schedule at a cost of more than $30 billion. Small modular reactors, with a power capacity of 300 megawatts or less, are...
Less nuclear waste- Fusion reactors will not produce high-level nuclear wastes like their fission counterparts, so disposal will be less of a problem. In addition, the wastes will not be of weapons-grade nuclear materials as is the case in fission reactors. ...
In the 1980s, scientists assessed the possible effects of nuclear warfare (many nuclear bombs exploding in different parts of the world) and proposed the theory that a nuclear winter could occur. In the nuclear-winter scenario, the explosion of many bombs would raise great clouds of dust and ...
