     Tritium has a half-life of twelve and a half years. So, it decays as time passes. Worse yet, its decay product is helium-3 which absorbs neutrons. It is critical that the boosting gas in a nuclear warhead is periodically refreshed. The exact interval for nuclear armed nations to refresh the tritium in their warheads is a closely guarded, classified secret. However, there is broad agreement between nuclear scientist that it is at most every ten years, and unlikely to be less than five years for practical reasons. Whatever the interval required, it is a simple matter of math to calculate that every bomb needs about two tenths of a gram of new tritium per year on average. Tritium costs thirty thousand dollars a gram.
     This means that, with forty-five hundred nuclear warheads, it should cost Russia on the order of thirty million dollars per year to maintain its nuclear arsenal. Even if they don’t keep the reserve warheads topped off with fresh tritium until they are needed, you have to have enough tritium on hand to fill them if they are needed immediately. So, whether or not you put the tritium in the bombs or not, it is a cost just to keep them available for service. Small tactical battlefield nukes are just as expensive to maintain as a full-sized hydrogen bomb that can destroy a whole city.
      Thirty million dollars is not a lot of money for Russia. But it is a lot of money for an individual if you can manage to steal it. For that reason, it is not unlikely that tritium intended for maintenance on nuclear warheads may have been stolen in Russia.
     Assuming a ten-year service interval, Russia needs to service about two bombs per workday to keep its arsenal fresh. The teams that do this maintenance are probably small. It would not require more than two to four people to service something the size of a bowling ball. A lot of teams are not needed. Two or three teams would probably be sufficient. The staff who do the maintenance work are very highly skilled and security cleared for such work.
    Every time one of these maintenance teams walk into a room to service a nuclear warhead, they carry a canister about the size of a fire extinguisher holding about eight grams of tritium. (You need enough to put in the bomb so that that ten years later, when it is next serviced, it will still have enough tritium to successfully ignite the expected explosion.) Each canister is worth about a quarter million dollars.
    Russian army ‘meals ready to eat’ (MREs) with an expiration date of 2015 can still be purchased on the international black market. Russian armored personnel carrier tires are failing in the field because they are cheap knockoffs of good tires and they aren’t being maintained properly. Russian tanks have to be regularly serviced and some of the problems with the Russian invasion have involved tanks that stalled on the road in Ukraine due to poor maintenance. Given this record, it is logical to believe that proper maintenance on nuclear warheads may not have been carried out in Russia.

Part 1 of 3 Parts
     Russia is the number two nuclear power in the world. They have about fifteen hundred warheads deployed on delivery systems and forty-five hundred in standby reserve. For years, Vladimir Putin, the President of Russia, has been brandishing his nuclear sword around the world. Russia has flown nuclear bombers through other countries airspace without warning. Russia has also been sailing nuclear armed ships and submarines through other countries territorial waters without warning. Years ago, he said that if Russia were losing a ground war to NATO troops with conventional weapons, he might use tactical nuclear weapons on the battlefield. However, there is one issue that might cause problems for Putin if he decides to use nuclear weapons. Do the warheads in the Russian arsenal actual work?
     It might seem unlikely that Russians nuclear weapons would not work but it is a possibility. There are two connected reasons that Russia might not actually be a nuclear power.
     First, nuclear weapons have what can be referred to as a “shelf life”. They are not like standard ammunitions that can be wrapped in grease paper and still function fifty years later. Nuclear warheads had critical parts made of radioisotopes which decay over time. They must be serviced regularly to replace those critical parts. There are several different components that must be replaced but one of the most important is tritium gas. Tritium gas is an radioactive isotope of hydrogen in which the nuclei contain one proton and two neutrons.
     The nuclear bomb dropped on Nagasaki, Japan, at the end of World War II. It weighed ten  thousand pounds and was six feet across. The explosion was equivalent to twenty thousand tons of TNT. It obliterated most of Nagasaki but was very impractical from a modern perspective.
      Modern nuclear fission weapons are “boosted” with tritium. They have hollow cores (referred to as ‘levitated’ cores) with a hollow sphere surrounding a smaller solid core which is suspended by wires in the center of the outer sphere. This configuration is more effective at compression. But it is not enough to make an atomic bomb the size of a bowling ball.
      In order to achieve that goal, tritium gas is pumped into the hollow space inside the levitated core. Modern bombs need between three and foud grams of tritium in order to achieve the desired fission reaction. The tritium fuses as it is compressed, which generates billions of neutrons. The initiators of Fat Man only released a few neutrons. The compression in modern warheads speeds up the reaction. This is critical for hydrogen bombs because they depend on the flash of gamma rays from the initial reaction to compress and react the secondary stage before everything is blown apart by the fission’s trigger atomic blast wave.
     This is also critical for tactical battle field nukes which must be lightweight and portable. It is safe to say that there are no un-boosted nuclear weapons in existence except possibly for a few prototypes in the possession of almost nuclear power like South Africa of North Korea.

     First Light Fusion is a laboratory based in Oxford, UK that aims to create clean energy using fusion technology. They have just installed the U.K.’s biggest ‘Two-Stage Hyper-Velocity Gas Gun’ in their effort to develop a simpler, faster, and cheaper route to commercial fusion energy. The laboratory’s new seventy-two feet one and a half million dollar hyper velocity gas gun can fire a projectile at seven and a half miles per second or twenty times the speed of sound. Six and a half pounds of gunpowder are required to fire the gun.
      First light has successfully fired first test shots. Experimental fusion shots are scheduled to start in June. The new gun will complement First Lights electromagnetic propulsion device ‘Machine 3’ to advance its projectile fusion technology.
     The gas gun operates by converting the energy released from an ignited propellant into the compression of a light gas such as hydrogen. This process creates gas pressures about ten thousand times sea level atmospheric pressure which then launches the projectile.
      When the gun is fired, it will launch a projectile into a vacuum chamber with enormous speed which then impacts a fusion target. The target is the centerpiece of First Light’s unique technology. That impact should create the conditions required for fusion.
      These ‘hyper velocity’ devices are typically utilized by astrophysicists to simulate meteorite impacts in space. A similar gun was used to test the panels on the International Space Station to ensure that it could withstand impacts from small object traveling at huge speeds.
     The gun will be used in parallel with First Light’s ‘Machine 3’. This will allow the engineers to explore a different parameter space by launching larger but ‘slower’ projectiles. It will be housed in a specifically constructed four-inch steel clad facility inside First Light’s headquarters in Oxford, referred to as ‘The Citadel’.
     Dr. Nick Hawker is the CEO of First Light Fusion. He said, “This new gun is an important piece of kit for First Light Fusion and will help us accelerate our development timeline. It will complement the work we are doing with our unique electromagnetic launch pulsed power machine, Machine 3.”
“Our fusion technology is driven by the impact of a projectile travelling at significant speed into a fusion target. These targets trade pressure and size, amplifying the pressure from initial impact to final collapse of the fuel capsule, which is a small part of the whole target.”
“This new gun will deliver lower pressure than Machine 3, so we will have to rely on designs that amplify more. The larger size means we can do this and still get good performance.”
“With both facilities together, we can make more than twice as much progress on the most important aspect of our technology, which is the target. Thank you to everyone for their efforts in bringing this project together so quickly, it has been a fantastic team effort once again.”
     The two-stage gas gun project took only ten months from concept design to the delivery of a fully operation test facility. First Light has remarked that this shows the great focus and effectiveness of their team.
