Q:I just watched the Chernobyl Diaries and it made me really interested with the actual disaster and the impact of it. I never really knew anything about it up until watching this movie and it just fascinates me. What happened that the nuclear plant exploded? Did people did from it? What is Chernobyl like today? Just some interesting facts about the whole thing would be great!

On April 26, 1986, the operating crew planned to test whether the Reactor No. 4 turbines could produce enough energy to keep the coolant pumps running until the emergency diesel generator was activated in case of an external power loss. During the test, power surged unexpectedly, causing an explosion and driving temperatures in the reactor to more than 2,000 degrees Celsius—melting the fuel rods, igniting the reactor’s graphite covering, and releasing a cloud of radiation into the atmosphere. The precise causes of the accident are still uncertain, but it is generally believed that the series of incidents that led to the explosion, fire and nuclear meltdown at Chernobyl was caused by a combination of reactor design flaws and operator error.

Q:Can bases be sources of electricity? Please explain why and cite your references. Thanks :)

base has many meanings. Air force bases sometimes have a diesel generator. Base hospitals almost always have diesel generators. A chemical base, together the right metals, can act as a electrochemical cell (battery). A base metal, such as zinc and copper, with the proper acid can act as a electrochemical cell (battery). .

Q:I would just like to know if this generator can run no veggable oil. It's the ETQ Portable Diesel Power Generators

A diesel engine can run on any oil,even lube oil.

Q:Diesel generator set how to put?

should not be located in the toilet and bathroom or other places are often the water below and adjacent;

Q:Can u plz help me to solve following problems:1.After an AC generator has been paralleled explain how the following are achieved for the incoming generator(i)Correct kW load sharing(ii)Correct load current when the generator has a different power factor to the other generators2. the cumulative damage that may be caused when the alternators are incorrectly synchronized3.For alternators operating in parallel the consequences of:(i)reduced torque from the prime mover of one machine(ii)reduced excitation on one machine

1. (i). Each engine should carry the SAME LOAD PERCENTAGE-wise, eg. 80%, to minimize the load change burden on the rest. (Smaller engines may run at full load, since their contribution may go unnoticed.) Since the overall kW bus load is constant, each generator will pickup a percentage of it, by controlling the torque on each prime mover. If it is a steam turbine, by throttling steam flow. If it is a diesel engine, by throttling fuel, and so. (ii). Each alternator should be adjusted to carry the SAME POWER FACTOR, by adjusting excitation accordingly, eg, .85, to avoid stability issues. Running alternators at leading power factors may turn the system unstable and force loss of synchronism 2. Considerable mechanical damage will be caused by incorrect synchronization to windings, shaft and keyways. 3. (i) reducing torque on one a prime mover is done when preparing to take it out of service. This has to be done gradually, so that other machines can pickup the load slowly. When close to unloaded, the generator can be taken off the grid. Power should never be reduced to the point of allowing the generator to be motored, i.e., reverse power flow, which can cause unpredictable damage to the turbine and system instability. (ii) reduced excitation is a very dangerous condition which will cause the power factor to turn leading, i.e., capacitive, weakening the synchronizing torque with possible loss of synchronism and forcing the bus voltage up. .

Q:A concert is in the works to raise money to help save the Everglades in Florida. I am looking to get as many people interested in the cause as possible. So what would make you want to go to this concert? Bands, the host, food, activities, location, day/night, etc.

For everyone to be required to bring some kind of rhythm instrument and have the world's largest audience participation with Gloria Estefan or Santana or some other Latin beat. Also, child friendly and family friendly.

Q:I am looking for back up power generator. Any suggestions?

For used medium size portable temporary units about $100 to $150 US per KW. Plus the required transfer switch and permits and inspections if you intend to power your house with it. This is for a manual start gasoline powered unit. As you add options the price goes up and may triple in hurricane season in the path of the storm. The quietest unit I've found are Honda, but they are more expensive. Any unit smaller than 15KW should be considered a short term unit good for maybe 2000 hours of run time. A 15 KW unit should be a permanent installation with a mounting pad and at least a 7 day supply of fuel on site. For this a licensed qualified professional electrical contractor should be consulted. As convenient as they may be, they can get to be expensive to install and operate.

Q:If the electrical grid fails and takes years to re-establish, how will the plants cool down?

Q:I guess the batteries are just extra weight - I'm not looking for an exact math answer, I could do the same thing. Or use a different gen, etc. to increase HP. I'm just interested in this concept of using the generator to move the vehicle along till real power is contributed by a battery bank.

As you increase horsepower, you increase weight. Refer back to your original question, I listed some useful answers that apply here as well. The basic principle you are thining of is exactly the principle of a modern Diesel electric locomotive short of the battery bank. As a concept- it is very workable. 3 Phase power has an advantage to it of space and weight savings for the horsepower versus single phase.

Q:Aside from the fact that they just had a massive natural disaster and there resources are stretched to say the least, what is main reason they cant get the reactor under control?From what I've heard it's not receiving enough power to maintain cooling system so it can maintain controlled fission.In my limited understanding it seems the plant survived relatively unscathed other than there diesel generators being flooded/destroyed. The plant is currently on battery backup's which I assume are relatively large and cant just be switched out to maintain the cooling system. Is it just an issue of supplying enough power for the cooling system? Couldn't they park the the USS Ronald Reagan off shore there and borrow some power until stabilized, considering you could power a sizable city off its reactor?

You could, but that's unnessecary at this point. The batteries supply enough power to the facility for them to shut down the reactor if they have to, so as long as they still have their kill switch there's no need for panic just yet.
