Wynn,
You are right, it is a part of the containment techniques, so it does not leak at final disposal sites. It is not the things that you want to continue to use. Maybe it can be done in the future, we do not know. At the moment, you do not want those balls. Sweden did however develop neighborhood reactors, 30 years ago, very safe and with low grade fuel and low temperatures, mainly central hot water production for heating applications. It was abandoned as a result of the Swedish referendum against nuclear power stations. The Japanese are now reintroducing the idea and are looking for the first test production sites in Canada.
