GodMode: Solar....good...but not effective (You lose 80% of power generated....plus you have to build a large Solar farm to generate light for a town. And it is expensive (1.6million naira to power a one room apartment). Wind...you need a very windy spot...eg mountains, and out into the sea. And it costs money too. Waste....when your governors do not have daily waste collection? Or you want govt to organise waste collection for every city and village in Nigeria? (You get money so?). |

Okijajuju1: We cant secure/properly maintain ordinary oil and gas pipeline, how are we going to secure nuclear sites toxic waste from the oil industry is been dumped callously, ordinary gas flaring we cannot stop, where will the nuclear waste be disposed? Will a correct/truthful EIA be conducted? Is living in darkness not better than what happened in chernobyl? is nuclear power the only other alternative to generating power? 2 Likes 1 Share |

GodMode: I think the Solar power project,(have peeped at the site....http://akonlightingafrica.com/our-activities/overview/) would just provide light for some bulbs, and maybe the television. For powering things like the fridge and other big electrical items.....you may need more than that. And it was 240million for 20000 households. May cost more to do it in Nigeria. |

bushdoc9919: Pls what do you mean human error? Is Nigeria immune a from such? Look at the last flood catastrophe, how did we handle it? The various bombing that has taken place, how was it handled? See corpses being carried in wheelbarrow & ambulance being used to carry more than one patient nuclear plant is good, the question is can we maintain it, in the event of an emergency can we handle it? We both know that the answer is NO Even if we want the Russians to build & operate it forever, you & I know that when there is an emergency, our corrupt leaders will take a bribe & look the other way What was the outcome of the botched immigration recruitment? 4 Likes 2 Shares |

MINISTER2000: Oga, cost of set-up per MW is cheaper with nuclear compared to solar. Solar is very costly and has limitations due to constrain of sun-hours. You must have backup system which is highly inefficient and vastly costly too; be it mechanical storage system or chemical (battery). Those countries you are mentioning (UK & Germany) are the richest in Europe, so stop comparing their choices with Nigeria's. Same with wind farms. They are capital intensive. Do you know how tall is a typical 10MW single unit of wind tower/turbine is? It is between 80 and 120m tall, that's like 40stories building with its base usually of about 40feet across! Germany and UK are installing hundreds of those silent giants on floating platforms anchored to seabeds on their coastlines offshore. That's a multi-billion dollar project , yet only a rich country can at yet afford such "luxury". Nigeria and every other third world country have no business with solar and wind mega projects, its not best use of our lean and scarce resources when we have alternatives of thermal, hydro and nuclear. harveyspec: What happens with T in the BOOT is not my decision. It is a public project which is normally influenced by lot of unmeasurable factors. Your refinery is not on same risk level with a nuclear plant, so what influences decision with one night not be same with other. I expect you to remind me again if Nigeria fell to Ebola virus when it got into the country. Nuclear waste for every nuclear plant in the world is under direct supervision of IAEA. So calm down and tame your ignorance. I'm sure you don't know that oil companies here in Nigeria have been using nuclear materials for their operation since forever, yet I'm yet to hear of any disaster so far. Technicians maintain power plants. I'm sure the nomenclature "technician" is hurting your ego somewhere. Note that what you call a technical is sometimes a PhD holder in quantum physics or engineering. It is simply the role he/she plays in the setup that matters. Plants runs with complement of several professional skills including accountants, tradesmen, technicians, scientists, administrators and lot more. We are building more gas plants, but we can't lay enough gas gathering facilities as required for constraint of fund and time. Also is the risk factor of sabotage of these facilities. But nuclear plant does away with need for such expensive and extensive feed stock facilities. Mind you, nuclear power is green energy. While gas is nonrenewable. |

ApexTitan: Yes sir! South Africa has nuclear plants. Congo DR has an old nuclear plant which I'm not sure of the state. I'm not sure about Egypt, but I will go through my library and confirm to you later. As matter of dact, Nigeria Energy Commission has a research nuclear power plant in Kaduna (?) which has been working for years. |

This is a welcome development for Nigeria though no credits to PMB cause he knows nothing about this project as I have followed for a while now but one fear I have Is the radical nature of or brothers in the north? A short break down on how the facility sets up below: Power is measured in watts or kilowatts (1,000 watts) or megawatts (one million watts. An electric generator is rated in watts. A large nuclear power plant has a power of 1,000 megawatts (or one gigawatt). If a one kilowatt generator runs for an hour, it produces a kilowatt-hour of electric energy. The amount of energy handled by humanity is still small compared to the amount of energy in the sunlight that strikes the earth. It's about one part in 50,000. Energy is conserved. It can be transformed among various forms, (e.g. mechanical, electrical, chemical, heat) but the total remains the same. In each transformation, some of the energy becomes unusable, usually in the form of heat. All matter is composed of elements. The important elements for our discussion of nuclear energy are uranium, plutonium, carbon and hydrogen. Uranium and plutonium are involved in nuclear energy production, and carbon and hydrogen are the main elements in conventional fuels like coal, oil and natural gas. An atom of an element consists of a nucleus surrounded by electrons. What element it is is determined by the number of protons in the nucleus, but the elements come in various isotopes, and the isotope is defined by the number of neutrons in the nucleus. Matter takes part in two kinds of reactions involving atoms of different kinds - chemical reactions and nuclear reactions. Chemical reactions are common and re-arrange how the atoms are combined into molecules but never change what element an atom is - or even what isotope it is. The reactions involved in the production and use of non-nuclear fuels are all chemical reactions. Nuclear reactions can change what element an atom is, occur on earth only under special conditions and involve something like ten million times the energy. Thus enormously more energy can be obtained from suitable nuclear reactions than from chemical reactions. Uranium has 92 protons. Two isotopes are important. U-235 has an atomic mass of 235 and U-238 has an atomic mass of 238. Natural uranium as it comes from mines contains 140 times as much U-238 as U-235. Because the 235 is the total of protons and neutrons U-235 has 235 - 92 = 143 neutrons. Plutonium has 94 protons. Its important isotopes are Pu-239, which is used in power plants and bombs, and Pu-240 which is ok in power plants but which is a nuisance for those making bombs out of plutonium. There is also Pu-238 which is not fissionable but emits alpha particles and thereby generates heat. The amount of heat produced is convenient for powering spacecraft systems. There is very little natural plutonium. When an atom of U-238 absorbs a neutron in a nuclear reactor, it becomes U-239, which decays in a short time to Pu-239. If a Pu-239 atom stays in the reactor long enough, it absorbs another neutron and becomes an atom of Pu-240 if it doesn't fission. When an atom of U-235 or plutonium absorbs a neutron it almost always fissions. Namely, it splits into two atoms of lighter elements and emits neutrons - on the average a bit more than two. The emitted neutrons can cause further fissions in a chain reaction. In a bomb the chain reaction is very fast; in a power reactor it is slow. The two fragments are emitted at high velocity, and when they are absorbed in the fuel rod a lot of heat is produced. This heat is what powers the nuclear power plant. Separating the isotopes of elements is very expensive. There are big plants for separating U-235 from the U-238 in natural uranium. For nuclear reactors, it is economical to use uranium that has been enriched to contain 4 to 5 percent U-235 instead of the 0.7 percent U-235 of natural uranium. Bombs need over 90 percent U-235. Separating Pu from U is not very expensive, and bombs are mostly made of Pu made from U in special reactors in which the Pu-239 is promptly removed. In ordinary power reactors, the Pu-239 gets contaminated with Pu-240. Separating Pu-240 from Pu-239 is very expensive. Here are some facts about nuclear power plants. Present nuclear power plants consume uranium (specifically U-235) as fuel. When the power plant is loaded with fuel, it can run for 18 months or 2 years before it has to be refuelled, a process that takes a month or two. As the power plant operators have become more experienced, they have learned to operate longer between refuellings and take a shorter time for refuelling. When an atom of U-235 absorbs a neutron it fissions, i.e. it breaks up in parts. These parts consist mainly of two atoms of smaller elements and some neutrons. When a reactor is operating, fission of an atom of U-235 generates on the average a bit more than two neutrons. If each of two neutrons produced by a fission was absorbed by an atom of U-235 the number of fissions would double in a fraction of second and then double again and again. If this were allowed to continue, in a few seconds the reactor would be generating enough power to melt. When the reactor is turned on, the multiplication of fissions is allowed to continue until the reactor is generating power at the desired rate. Then control rods that absorb neutrons are inserted until exactly one neutron from each fission causes another fission. Because some of the neutrons caused by a fission are emitted from the fission products only after a delay of a minute or so, it is not difficult to control the power level of the reactor. Nevertheless, there are safety systems that will shut down the reactor if the power level gets too high or if the cooling water stops flowing. The power to produce electricity comes from the fact that the two atoms produced by the fission of a U-235 atom fly off at high speed, but they don't get even an inch before they hit something and are stopped. Stopping converts their energy of motion into heat, and the reactor heats up. If the heat weren't taken away, the reactor would melt. The heat from fission is taken up by water or steam pumped through the reactor. The hot steam goes through turbines connected to electric generators. About 2/3 of the heat energy is lost, and is emitted to the atmosphere or to a body of water, a river or the ocean. This loss is a consequence of the Second Law of Thermodynamics and applies to all power plants, nuclear or coal-burning. If the highest temperature in the steam plant is T1 and the temperature at which heat is exhausted to the environment is T2, the fraction of the heat generated that can be turned into electricity is (T1 - T2)/T1. The fraction of the heat energy transformed into electric energy is called the efficiency of the power plant. For high efficiency T1 should be as high as possible and T2 as low as possible. How high T1 can be is determined by how high a temperature the materials of the reactor can be without softening. How low T2 can be is limited by the environment. Cold seawater gives a good T2. After 18 months or two years, most of the U-235 in the fuel is used up, and the fuel rods consist mainly of the products of fission, which remain radioactive and continue to generate heat. The fuel rods are placed in large pools of water which takes the remaining heat. The fuel rods become less and less radioactive with time. After the rods have cooled off for a while, they should be chemically reprocessed to extract left over uranium and some plutonium that has been produced. The left-over uranium and the plutonium can then be converted to more reactor fuel. The fission products can then be buried in stable rock formations 1 Like |
