First, I'm infinitely skeptical that any kind of fusion will occur with virtual mesons, some of which decay to muons with "mostly" virtual energy. For anything interesting to happen, I'm assuming you will need real mesons and real muons. I understand that mesons can lead to nuclear reactions on their own. But for the sake of thinking things through, we can ask how many muons would be needed for 1 Watt power production (if only muons were catalyzing nuclear reactions). Consider that a typical nickel proton capture reaction will yield ~ 5 MeV. That means 1 Joule * s^-1 = 6.24e12 MeV * s^-1 = 1.25e12 proton captures * s^-1. Using your number, a muon can catalyze 150 reactions. Assuming this is the right order of magnitude not only for d+t muon catalyzed fusion but also for proton capture in nickel, I think over time that would average out to around 1.25e12 captures * s^-1 / (150 captures * muon^-1) = 8.32e9 muons per second which would need to be produced by the magnetic field. The muons will come about as a result of pion decays, for which we will need 8.32e9 negative pions per second. The energy needed to produce a negative pion is ~ 140 MeV. Your challenge, then, would seem to be to work out how strong a magnetic field is needed to generate 8.32e9 pions per second along the Boltzmann tail (assuming a Boltzmann distribution). Even if the energy needed for the pion production is found in the long tail, I'm guessing the average energy of the distribution will still be considerable at this rate of production. I'm also skeptical that human beings have ever even created a magnetic field that is strong enough to simply will negative pions from out of the vasty deep. (If anyone spots a mistake in any of these calculations, please call it out.) Note that a negative muon reacts with a proton to create a neutral pion and a neutron. Note also that a proton capture in nickel is likely to cause short-lived radioisotopes and energetic states in the daughter nuclei which will need to decay somehow. This is likely to happen through beta and beta plus decay, and there's likely to be annihilation photons. So if this is what is going on it would seem to be inconsistent with your assumption early in the article about radioactive byproducts: "The fact that no radioactive isotopes are found in the ash of the cold fusion reaction is unequivocal proof ...".
