Key to the DOE's nuclear project are the federal laboratories where nuclear weapons are designed, built, and tested. They include Sandia National Laboratory in Albuquerque, New Mexico, Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico, and Lawrence Livermore National Laboratories in Livermore, California.

 When a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons and some binding energy. Two neutrons do not continue the reaction because they are lost or absorbed by a uranium-238 atom. ... This causes a nuclear chain reaction.


The RDS-220 hydrogen bomb, also known as the "Tsar Bomba", is the biggest and most powerful thermo nuclear bomb ever detonated. It was exploded by the Soviet Union on 30 October 1961 over Novaya Zemlya Island in the Russian Arctic Sea. The hydrogen bomb was air dropped by a Tu-95 bomber.



f a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. Second, thermal radiation, as usually defined, also disappears.

How to make a nuclear bomb.

Then eight or nine months to extract the Plutonium, design and build the bomb. That's pretty fast too. Today, we might be able to do that a little faster too but not much. So, it took the Manhattan Project scientists about 2.5 years, so we might be able to do is in 2 to 2.5 years.

The basic mechanism of an atomic bomb. Once you've made enough uranium-235, though, creating critical mass is relatively easy. You start out with two smaller lumps of uranium and, when it's time to set the bomb off, bang them together at high speed. 

Fusion weapons are more complex.Oppenheimer was the wartime head of the Los Alamo Laboratory and is among those who are credited with being the "father of the atomic bomb" for their role in the Manhattan Project, the World War II undertaking that developed the first nuclear weapons.

inhaling large concentrations of uranium can cause lung cancer from the exposure to alpha particles. Uranium is also a toxic chemical, meaning that ingestion of uranium can cause kidney damage from its chemical properties much sooner than its radioactive properties would cause cancers of the bone or liver.

Hurumanu: Climate Change and the future

Hurumanu: Climate Change and the future

Aim; To look at the different ways we can prevent climate change in the future.

How is sea level rise going to effect us in NZ

What else do we need to think about? 

Places near rivers and homes near homes. 

What other places around NZ will be affected?

What places will be effected? Pacifist Island NZ different Places.

What does this do to our drinking water?

We don't have much good water left and it will turn bad

What are the main concerns?

Climate change can also result from external forcing, when events outside of the climate system's components nonetheless produce changes within the system. Examples include changes in solar output and volcanic. Human activities can also change 
climate, and are presently driving climate change through global warming.

What can we do to prevent climate change?

What can we do?

1. Speak up! 
2. Power your home with renewable energy. 
3. Weatherise, 
4. Invest in energy-efficient appliances. 
5. Reduce water waste. 
6. Actually eat the food you buy—and make less of it meat. 
7. Buy better bulbs. 
8. Pull the plug's 

    

Curbing climate change

What is the one, silver bullet solution?

What is the mix of things we need to start doing?

1.   stark waling 
2.   use less power 
3.    stop littering  

What are 3 others you can think of?

• Change a light. 
• Drive less. 
• Recycle more. 
• Check your tires. 
• Use less hot water. 
• Avoid products with a lot of packaging. 
• Adjust your thermostat. 
• Plant a tree.
