More description materials here are forthcoming once data entry volunteers are identified.
Neutrons emanating from a muon catalyzed fusion reactor can be collimated onto a suitably absorbing blanket around the reactor, absorbing energy and spallating further neutrons which similarly can be absorbed by a suitable blanket of waste, effecting a transmutation of the waste. This form of mATW requires the infrastructure of a muon beam generation system which is a particle accelerator which could be engineered on demand today deploying conventional pre-existing technology.
The collimation system is unique to mATW is not possible in tATW though it might be possible for a proton accelerator form of sATW.
Initial contact was invited by the Ukrainian government for a letter of intent they could present to US State Dept officials meeting them in Kiev in October 2017 to discuss Chernobyl nuclear waste management issues. I wrote that letter cc'ing Ukraine and State of Maine government officials. In November 2017 I received responses from 2 Ukrainian agencies and the Kiev Institute of Nuclear Physics (KINP). These are available upon request. US Dept of Energy officials have been contacted as well, who provided the appropriate agency (NETL) through which to apply for funding to establish initial efforts for a new evaluation mATW (since the last evaluation of ATW was 20+ years ago). Ultimately there is a significant potential that contributions are possible internationally: Ukraine, Japan, Canada, UK and USA governments.
