Engineering360: "Video: This microreactor is a MARVEL"

I am very pleased to see this technology emerge....now if I can just get one for my flying car and house...

Fill 'er up!

The article conveniently omitted as to how the waste is to be disposed. Will it be safeguarded by humans for the next 50000 years? 10000 years?

It could be recycled as fuel...

I'd say this is off-topic. Nuclear waste is a different issue that is extensively covered elsewhere. Much of the problem is political, not technological. We could reprocess the waste to get the plutonium-239 produced by neutron absorption, but politics prohibits it. We could separate out the long-life radioactive elements to reduce the volume of long-term waste, but politics won't let it be considered. We could just fuse the whole mess into large pieces of glass and bury it under Yucca Mountain, but again, politics won't permit it. The technology exists, but so does a significant amount of superstition about radioactivity, along with understandable concerns about having a reprocessing facility next door.

But all of that is separate matter from the achievement of a "micro-reactor." We shouldn't demand a solution for the waste issue also as a condition of giving credit for this development.

No. Every project must be evaluated from the time it comes from the earth to the time it returns to the earth. The project must not leave any long lasting harm to the earth. Leaving highly radioactive waste around for 50000 years definitely leaves harm to the earth. How could anybody believe humans could keep this waste safely for 50000 years? With all the recycling of the spent rods, there's always some super radioactive material left that must be guarded for 50000 years.
