Ryan Hunt (HUG, MFMP) did a post-mortem on the reactor tube from the first experiment with the dogbone and fuel as described by Parkhomov. He found a gross failure of the seal of the plug in the tube. Also, because he didn't shake it to distribute the powder, the powder ended up in the opposite end from the plug in a bunch. The next focus will be on the seal.
