Why nuclear power will never supply the world's energy needs May 11, by Lisa Zyga, Phys. As Abbott notes in his study, global power consumption today is about 15 terawatts TW. Currently, the global nuclear power supply capacity is only gigawatts GW. In order to examine the large-scale limits of nuclear power, Abbott estimates that to supply 15 TW with nuclear only, we would need about 15, nuclear reactors.

In his analysis, Abbott explores the consequences of building, operating, and decommissioning 15, reactors on the Earth, looking at factors such as the amount of land required, radioactive waste, accident rate, risk of proliferation into weapons, uranium abundance and extraction, and the exotic metals used to build the reactors themselves.

Even a supply of as little as 1 TW stretches resources considerably. One nuclear reactor plant requires about Secondly, nuclear reactors need to be located near a massive body of coolant water, but away from dense population zones and natural disaster zones.

Simply finding 15, locations on Earth that fulfill these requirements is extremely challenging. Every nuclear power station needs to be decommissioned after years of operation due to neutron embrittlement - cracks that develop on the metal surfaces due to radiation.

If nuclear stations need to be replaced every 50 years on average, then with 15, nuclear power stations, one station would need to be built and another decommissioned somewhere in the world every day.

Currently, it takes years to build a nuclear station, and up to 20 years to decommission one, making this rate of replacement unrealistic. Although nuclear technology has been around for 60 years, there is still no universally agreed mode of disposal. To date, there have been 11 nuclear accidents at the level of a full or partial core-melt.

These accidents are not the minor accidents that can be avoided with improved safety technology; they are rare events that are not even possible to model in a system as complex as a nuclear station, and arise from unforeseen pathways and unpredictable circumstances such as the Fukushima accident.

Considering that these 11 accidents occurred during a cumulated total of 14, reactor-years of nuclear operations, scaling up to 15, reactors would mean we would have a major accident somewhere in the world every month. The more nuclear power stations, the greater the likelihood that materials and expertise for making nuclear weapons may proliferate.

Although reactors have proliferation resistance measures, maintaining accountability for 15, reactor sites worldwide would be nearly impossible.

At the current rate of uranium consumption with conventional reactors, the world supply of viable uranium, which is the most common nuclear fuel, will last for 80 years. Scaling consumption up to 15 TW, the viable uranium supply will last for less than 5 years.

Viable uranium is the uranium that exists in a high enough ore concentration so that extracting the ore is economically justified. Uranium extraction from seawater: Theoretically, that amount would last for 5, years using conventional reactors to supply 15 TW of power.Aug 16,  · Don’t be brainwashed in believing that nuclear energy is clean and the only way forward.

By accepting it you also accepting that war and nuclear Status: Resolved. Current Press News November 08, — Nuclear host communities weigh in on waste characterization — Representatives from multiple communities that host nuclear activities publicly supported a proposal by the U.S.

Department of Energy to change its definition of high-level nuclear waste (HLW), potentially downgrading some HLW to either low-level or transuranic (TRU) waste — .

Introduction to nuclear energy. Everything around you is made up of atoms. In the late s, it was discovered that some particularly large atoms can split in two (or fission), releasing a shockingly large amount of these atoms were arranged properly in a machine, one splitting atom can cause nearby ones to split, creating a chain reaction.
