So the challenge is simple: to create a boosted fusion nuke without using tritium as fusion fuel.
I created this challenge because guys in this forum love to use tritium as fuel to boost the performance of their nuke. But irl tritium boosted nuke require regular refuel of tritium as tritium decay over time and thus affect the fireball size in action if not replenish regularly. And it affect long term storage of nuclear weapons. And that why I posted this challenge.
I would also use a formula to measure the effectiveness of your guy's tritium free nuke: yield in equivalent of killoton of TNT divided by the mass of the design in kg. For example if a design have a mass of 100 kg have a yield of 10kt it will get a score of 0.1. A ranking would be used to compare the effectiveness of designs from players.
You do realize that tritium is radioactive with half-life of 12.32 years, right? This means that traveling for years can affect the nuke's yield dramatically, especially for low-tech ships without the ability to breed tritium.
