NO radioactive waste, detailed calculations

Radioactive waste means material with radioactivity at a level that is dangerous to organisms. Everything contain some radioactivity, even us. But Focus Fusion generators produce no radioactive waste.
Here is a small, rough, calculation about the amount of radioactivity produced in the beryllium electrodes during the month they are in a Focus Fusion generator.

Rate of aneutronic reactions:
7×10^18/s

Secondary neutrons per aneutronic reaction (our calculation—some other estimates are as low as 1/1000)
1/200

Proportion of neutrons absorbed by Be9 electrode to produce Be10 (cross section 0.1 mbarns; average depth of Be 1 cm)
1/75,000

Rate of Production of Be10 nuclei
4.7×10^11/s

Total Be10 nuclei produce in 1 month
1.2×10^18

Rate of decay of this many Be10 nuclei (Be10 half life 1.4My)

2.9×10^4 decay/s

Equals 0.8 micro curies of radioactivity in each used set of electrodes.

Radioactivity of human child –about 0.2 micro curies
Radioactivity of classroom of 25 children—5 micro curies

This is why we won’t need to worry about the radioactivity of the Be electrodes before they are recycled.

Let’s just look at the tritium numbers.

3.5 billion neutrons for each J of fusion produced.

9 million Li6 nuclei from reactions with Be9 in the electrodes. (cross section 20 mbarns)

In a month in a 5MW generator, about 350 of those Li6 nuclei will be hit by neutrons and react to produce tritium nuclei. (cross section 250 mbarns)

So we have 350 tritium nuclei per J of fusion energy with focus fusion vs , for example, 430 billion tritium nuclei per J of fusion energy with a tokamak.

The tritium will mostly end up in the helium exhaust or helium cooling fluid of the Focus Fusion generator. Total tritium production in a month: 44 nanogms or 630 microcuries. The safety limit for tritium in drinking water in the US is 20 nanocuries per liter of water. So just diluting the tritum (and the helium it is with) in 1,000 gallons a day of water would make it safe. That’s the water usage of 3 typical Us families. Less than 1 microcurie will still be left in the Be electrodes. So this is why we don’t worry about tritium.
Bottom line—NO radioactive waste.
