Iran and the West have been in a major tradeoff since the last couple of years with Iran’s enrichment of uranium which can be used to make nuclear weapons. Note the recent tensions were escalated with the EU joining the US in embargoing Iran. This has not gone unnoticed by the Iranian government which has threatened to close the Strait of Hormun which could disrupt a major portion of the global oil supplies.

Note one of the main dangers of nuclear energy is the probability of the fuel getting into the hands of terrorists and rogue nations which can use it to make nuclear weapons. Note the fears of a Taliban like group getting their hands on nuclear arms in Pakistan is all too real.With Iran getting nuclear weapons, this will increase. Nuclear Power is already being phased out in Germany,Japan,Switzerland after the Fukushima nuclear disaster. The dangers of  nuclear energy are too great to make it an option to secure mankind’s energy in the future.Despite the advantages of nuclear power, the risks are too great to be played with.

DISADVANTAGES OF NUCLEAR POWER

1. Nuclear and Radiation Accidents – This is the biggest con for Nuclear Energy and has been repeated 3 times in the last 30 years in Japan,Russia and USA.The fear of a repeat is so great that despite all the safety arrangements touted by the nuclear equipment operators and suppliers,Nuclear Energy faces an uncertain future
2. Nuclear Waste Disposal – Again a massive problem as the spent Nuclear Rods of Nuclear Reactors are prohibitively costly and difficult to dispose of.Spent nuclear fuel is initially very highly radioactive and so must be handled with great care and forethought.There is no foolproof way to dispose nuclear waste fuel after it is used in the Nuclear Reactors.The area around Nuclear Waste Sites can be dangerous to humans for hundreds of year as complex nuclear elements have half lives running into many years.the United States had accumulated more than 50,000 metric tons of spent nuclear fuel from nuclear reactors.Permanent storage underground in U.S. had been proposed at the Yucca but that project has now been effectively cancelled.Presently, waste is mainly stored at individual reactor sites and there are over 430 locations around the world where radioactive material continues to accumulate.
3. Low level of Radioactivity from Normal Operations – The nuclear industry also produces a large volume of low-level radioactive waste in the form of contaminated items like clothing, hand tools, water purifier resins, and (upon decommissioning) the materials of which the reactor itself is built
4. Nuclear proliferation – Many countries have used the ruse of nuclear energy programs to generate fuel for developing nuclear weapons.Currently there is a major international controversy with regards to the Iranian Nuclear Energy Program.Nuclear Reactors are targets for rogue state actors who can steal the fuel for creating radiation weapons
5. High Capital Investment,Cost Overruns and Long Gestation Time – The time to construct a large Nuclear power project can take between 5-10 years which leads to time and cost overruns.The Nuclear Plant being built in Finland has been one of the biggest failures in Project Finance.The reactor has been delayed by many year and has led to a massive cost overrun.Areva the main nuclear equipment supplier has endured huge losses.In fact the safety regulations and the long time of construction has brought the Nuclear Energy in the Developed World to almost a halt.
6. Regulations – The Regulations for Nuclear Energy Power Plants are many and cumbersome due to the massive risks of a failure of a nuclear reactor.This greatly increases the costs of generating nuclear power.It also leads to a long time in the actual start to the completion of a Nuclear Plant .
7. Fuel Danger – Uranium which is the main fuel used in Nuclear Fission Power Plants is limited to a few countries and suppliers.Its use and transport is regulated by international treaties and groups.India which came under sanctions because of testing of nuclear weapons had to shut many of its nuclear plants because of embargoes.

Iran has started enriching uranium to more than 20% which has surprised the West at a plant near the holy city of Qom

The existence of the Fordo plant, built into the side of a mountain near the Muslim holy city of Qom, south of Tehran, was disclosed in September 2009, heightening concern among the U.S. and its allies who say Iran’s activities may be a cover for the development of atomic weapons. The Persian Gulf country has rejected the allegation, saying it needs nuclear technology to secure energy for its growing population.Jan. 8 (Bloomberg) — Iran has started to enrich uranium at its Fordo production facility, the official Kayhan newspaper reported without saying where it got the information.
