US nuclear-fusion lab enters new era: achieving 'ignition' over and over

So, we may be able to make tetraneutrons:

Is this something we can use for spaceflight?
Let's suppose it's possible to make long term stable tetraneutron matter. Is there some way we could store it in some sort of containment trap?
If so, could it be used for some sort of cheap powerful fission drive? I'm thinking the fuel is cheap uranium 238 or thorium maybe combined with lithium deuteride. The tetraneutrons provide a burst of neutrons to "catalyze" fission ... the charged particles from the reaction are deflected by magnetic field for thrust.
Basically, I'm thinking something similar to anti-matter catalyzed fission, but with tetraneutron matter ... of some sort. Somehow?
Is this an idea that even makes sense?

First of: no fan of cancer.
In both cases: Fission and Fusion the user is dealing with cancer causing nuclear (gamma and neutron) radiation.
The advantage of Fusion over Fission is: no need for colonial style of war efforts in Africa (Mali) to secure uranium deposits.
The dissadvantage of Fusion: it is a mammoth of a project too grant to be tackled by one nation alone (China got close, but is still +50 Million C (122 Million F) short of it’s +170 Million C (338 Million F) goal.
In the face of climate change, France is betting everything on nuclear (France in 2021 has 50x!!! nuclear reactors! only second to USA) and right now, CO2 wise it comes on top of Germany that just switched off another 3 nuclear power plants.
Problem:
- since Fukushima, inssurance costs for nuclear power plants have risen dramatically making it actually not pay off without gov subsidies
- nuclear power was subsidized in Germany from 1950 until 2010 with 304 Billion € (5 Billion € per year)
That is 4,3Cent per 1kWh
China confident that they can do it “in 10 years”, maybe in 20, maybe in 30.
“For example, Chinese state media report that a temperature of at least 70 million degrees Celsius could be maintained in the experimental reactor for 17 minutes. This represents an important breakthrough. Because, obviously, the physical difficulties have been overcome. The duration of the heat formation thus depends only on the question of how much energy you put into it. If you like, the researchers are still about 50 million degrees away from their goal. When this will be achieved, it is again difficult to say. The Chinese media are quite optimistic and name a period of ten years”

According to Robert Seinhaus (LLNL) a relatively $50.000 cheap combination-energy device of “first stage” 3% fission (with uranium) and 97% fusion (no uranium but maybe also expensive materials) was already successfully tested. (molten salt cooling is his favorite way of cooling, which might make it interesting to be operated in the desert? (far away from cities and in no need for rivers to cool it?)
